Aims. Multiple secondary surgical procedures of the shoulder, such as soft-tissue releases, tendon transfers, and osteotomies, are described in brachial plexus birth palsy (BPBP) patients. The long-term functional outcomes of these procedures described in the literature are inconclusive. We aimed to analyze the literature looking for a consensus on treatment options. Methods. A systematic literature search in healthcare databases (PubMed, Embase, the Cochrane library, CINAHL, and Web of Science) was performed from January 2000 to July 2020, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. The quality of the included studies was assessed with the Cochrane ROBINS-I risk of bias tool. Relevant trials studying BPBP with at least five years of follow-up and describing functional outcome were included. Results. Of 5,941 studies, 19 were included after full-text screening. A total of 15 surgical techniques were described. All studies described an improvement in active external rotation (range 12° to 128°). A decrease in range of motion and Mallet score after long-term (five to 30 years) follow-up compared to short-term follow-up was seen in most studies. Conclusion. The literature reveals that functional outcome increases after different secondary procedures, even in the long term. Due to the poor methodological quality of the included studies and the variations in indication for surgery and surgical techniques described, a consensus on the long-term functional outcome after secondary surgical procedures in BPBP patients cannot be made.

Aims. The aim of this study was to determine the effectiveness of home-based prehabilitation on pre- and postoperative outcomes in participants awaiting total knee (TKA) and hip arthroplasty (THA). Methods. A systematic review with meta-analysis of randomized controlled trials (RCTs) of prehabilitation interventions for TKA and THA. MEDLINE, CINAHL, ProQuest, PubMed, Cochrane Library, and Google Scholar databases were searched from inception to October 2022. Evidence was assessed by the PEDro scale and the Cochrane risk-of-bias (ROB2) tool. Results. A total of 22 RCTs (1,601 patients) were identified with good overall quality and low risk of bias. Prehabilitation significantly improved pain prior to TKA (mean difference (MD) -1.02: p = 0.001), with non-significant improvements for function before (MD -0.48; p = 0.06) and after TKA (MD -0.69; p = 0.25). Small preoperative improvements were observed for pain (MD -0.02; p = 0.87) and function (MD -0.18; p = 0.16) prior to THA, but no post THA effect was found for pain (MD 0.19; p = 0.44) and function (MD 0.14; p = 0.68). A trend favouring usual care for improving quality of life (QoL) prior to TKA (MD 0.61; p = 0.34), but no effect on QoL prior (MD 0.03; p = 0.87) or post THA (MD -0.05; p = 0.83) was found. Prehabilitation significantly reduced hospital length of stay (LOS) for TKA (MD -0.43 days; p < 0.001) but not for THA (MD, -0.24; p = 0.12). Compliance was only reported in 11 studies and was excellent with a mean value of 90.5% (SD 6.82). Conclusion. Prehabilitation interventions improve pain and function prior to TKA and THA and reduce hospital LOS, though it is unclear if these effects enhance outcomes postoperatively.

Aims. Avulsion of the proximal hamstring tendon origin can result in significant functional impairment, with surgical re-attachment of the tendons becoming an increasingly recognized treatment. The aim of this study was to assess the outcomes of surgical management of proximal hamstring tendon avulsions, and to compare the results between acute and chronic repairs, as well as between partial and complete injuries. Methods. PubMed, CINAHL, SPORTdiscuss, Cochrane Library, EMBASE, and Web of Science were searched. Studies were screened and quality assessed. Results. In all, 35 studies (1,530 surgically-repaired hamstrings) were included. Mean age at time of repair was 44.7 years (12 to 78). A total of 846 tears were acute, and 684 were chronic, with 520 tears being defined as partial, and 916 as complete. Overall, 92.6% of patients were satisfied with the outcome of their surgery. Mean Lower Extremity Functional Score was 74.7, and was significantly higher in the partial injury group. Mean postoperative hamstring strength was 87.0% of the uninjured limb, and was higher in the partial group. The return to sport (RTS) rate was 84.5%, averaging at a return of 6.5 months. RTS was quicker in the acute group. Re-rupture rate was 1.2% overall, and was lower in the acute group. Sciatic nerve dysfunction rate was 3.5% overall, and lower in the acute group (p < 0.05 in all cases). Conclusion. Surgical treatment results in high satisfaction rates, with good functional outcomes, restoration of muscle strength, and RTS. Partial injuries could expect a higher functional outcome and muscle strength return. Acute repairs result in a quicker RTS with a reduced rate of re-rupture and sciatic nerve dysfunction.

Aims. Loosening of components after total knee arthroplasty (TKA) can be associated with the development of radiolucent lines (RLLs). The aim of this study was to assess the rate of formation of RLLs in the cemented original design of the ATTUNE TKA and their relationship to loosening. Methods. A systematic search was undertaken using the Cochrane methodology in three online databases: MEDLINE, Embase, and CINAHL. Studies were screened against predetermined criteria, and data were extracted. Available National Joint Registries in the Network of Orthopaedic Registries of Europe were also screened. A random effects model meta-analysis was undertaken. Results. Of 263 studies, 12 were included with a total of 3,861 TKAs. Meta-analysis of ten studies showed high rates of overall tibial or femoral RLLs for the cemented original design of the ATTUNE TKA. The overall rate was 21.4% (95% confidence interval (CI) 12.7% to 33.7%) for all types of design but was higher for certain subgroups: 27.4% (95% CI 13.4% to 47.9%) for the cruciate-retaining type, and 29.9% (95% CI 15.6% to 49.6%) for the fixed-bearing type. Meta-analysis of five studies comparing the ATTUNE TKA with other implants showed a significantly higher risk of overall tibial or femoral RLLs (odds ratio (OR) 2.841 (95% CI 1.219 to 6.623); p = 0.016) for the ATTUNE. The rates of loosening or revision for loosening were lower, at 1.2% and 0.9% respectively, but the rates varied from 0% to 16.3%. The registry data did not report specifically on the original ATTUNE TKA or on revision due to loosening, but ‘all-cause’ five-year revision rates for the cemented ATTUNE varied from 2.6% to 5.9%. Conclusion. The original cemented ATTUNE TKA has high rates of RLLs, but their clinical significance is uncertain given the overall low associated rates of loosening and revision. However, in view of the high rates of RLLs and the variation in the rates of loosening and revision between studies and registries, close surveillance of patients who have undergone TKA with the original ATTUNE system is recommended.

Aims. This systematic review and meta-analysis was conducted to compare open reduction and internal fixation (ORIF) with primary arthrodesis (PA) in the treatment of Lisfranc injuries, regarding patient-reported outcome measures (PROMs), and risk of secondary surgery. The aim was to conclusively determine the best available treatment based on the most complete and recent evidence available. Methods. A systematic search was conducted in PubMed, Cochrane Controlled Register of Trials (CENTRAL), EMBASE, CINAHL, PEDro, and SPORTDiscus. Additionally, ongoing trial registers and reference lists of included articles were screened. Risk of bias (RoB) and level of evidence were assessed using the Cochrane risk of bias tools and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) tool. The random and fixed-effect models were used for the statistical analysis. Results. A total of 20 studies were selected for this review, of which 12 were comparative studies fit for meta-analysis, including three randomized controlled trials (RCTs). This resulted in a total analyzed population of 392 patients treated with ORIF and 249 patients treated with PA. The mean differences between the two groups in American Orthopedic Foot and Ankle Society (AOFAS), VAS, and SF-36 scores were -7.41 (95% confidence interval (CI) -13.31 to -1.51), 0.77 (95% CI -0.85 to 2.39), and -1.20 (95% CI -3.86 to 1.46), respectively. Conclusion. This is the first study to find a statistically significant difference in PROMs, as measured by the AOFAS score, in favour of PA for the treatment of Lisfranc injuries. However, this difference may not be clinically relevant, and therefore drawing a definitive conclusion requires confirmation by a large prospective high-quality RCT. Such a study should also assess cost-effectiveness, as cost considerations might be decisive in decision-making. Level of Evidence: I. Cite this article: Bone Jt Open 2021;2(10):842–849

Aims. With up to 40% of patients having patellofemoral joint osteoarthritis (PFJ OA), the two arthroplasty options are to replace solely the patellofemoral joint via patellofemoral arthroplasty (PFA), or the entire knee via total knee arthroplasty (TKA). The aim of this study was to assess postoperative success of second-generation PFAs compared to TKAs for patients treated for PFJ OA using patient-reported outcome measures (PROMs) and domains deemed important by patients following a patient and public involvement meeting. Methods. MEDLINE, EMBASE via OVID, CINAHL, and EBSCO were searched from inception to January 2022. Any study addressing surgical treatment of primary patellofemoral joint OA using second generation PFA and TKA in patients aged above 18 years with follow-up data of 30 days were included. Studies relating to OA secondary to trauma were excluded. ROB-2 and ROBINS-I bias tools were used. Results. A total of nine studies were included, made up of four randomized controlled trials (domain 1) and five cohort studies (domain 2). PROMs and knee function specific scores developed for reporting TKA were unable to detect any difference between PFA and TKA. There was no significant difference in complications between PFA and TKA. PFAs were found to have a better postoperative range of motion. Conclusion. TKA and PFA are both viable options for patients with primary PFJ OA. Over time, we have seen an emphasis on patient satisfaction and better quality of life. Recommending sacrificing healthy medial and lateral compartments to treat patellofemoral joint arthritis should be given further thought. Cite this article: Bone Jt Open 2023;4(12):948–956

Aims. Revision rates for ankle arthroplasties are higher than hip or knee arthroplasties. When a total ankle arthroplasty (TAA) fails, it can either undergo revision to another ankle replacement, revision of the TAA to ankle arthrodesis (fusion), or amputation. Currently there is a paucity of literature on the outcomes of these revisions. The aim of this meta-analysis is to assess the outcomes of revision TAA with respect to surgery type, functional outcomes, and reoperations. Methods. A systematic review was conducted using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed, Medline, Embase, Cinahl, and Cochrane reviews were searched for relevant papers. Papers analyzing surgical treatment for failed ankle arthroplasties were included. All papers were reviewed by two authors. Overall, 34 papers met the inclusion criteria. A meta-analysis of proportions was performed. Results. Six papers analyzed all-cause reoperations of revision ankle arthroplasties, and 14 papers analyzed failures of conversion of a TAA to fusion. It was found that 26.9% (95% confidence interval (CI) 15.4% to 40.1%) of revision ankle arthroplasties required further surgical intervention and 13.0% (95% CI 4.9% to 23.4%) of conversion to fusions; 14.4% (95% CI 8.4% to 21.4%) of revision ankle arthroplasties failed and 8% (95% CI 4% to 13%) of conversion to fusions failed. Conclusion. Revision of primary TAA can be an effective procedure with improved functional outcomes, but has considerable risks of failure and reoperation, especially in those with periprosthetic joint infection. In those who undergo conversion of TAA to fusion, there are high rates of nonunion. Further comparative studies are required to compare both operative techniques.

Aims. Clinical management of open fractures is challenging and frequently requires complex reconstruction procedures. The Gustilo-Anderson classification lacks uniform interpretation, has poor interobserver reliability, and fails to account for injuries to musculotendinous units and bone. The Ganga Hospital Open Injury Severity Score (GHOISS) was designed to address these concerns. The major aim of this review was to ascertain the evidence available on accuracy of the GHOISS in predicting successful limb salvage in patients with mangled limbs. Methods. We searched electronic data bases including PubMed, CENTRAL, EMBASE, CINAHL, Scopus, and Web of Science to identify studies that employed the GHOISS risk tool in managing complex limb injuries published from April 2006, when the score was introduced, until April 2021. Primary outcome was the measured sensitivity and specificity of the GHOISS risk tool for predicting amputation at a specified threshold score. Secondary outcomes included length of stay, need for plastic surgery, deep infection rate, time to fracture union, and functional outcome measures. Diagnostic test accuracy meta-analysis was performed using a random effects bivariate binomial model. Results. We identified 1,304 records, of which six prospective cohort studies and two retrospective cohort studies evaluating a total of 788 patients were deemed eligible for inclusion. A diagnostic test meta-analysis conducted on five cohort studies, with 474 participants, showed that GHOISS at a threshold score of 14 has a pooled sensitivity of 93.4% (95% confidence interval (CI) 78.4 to 98.2) and a specificity of 95% (95% CI 88.7 to 97.9) for predicting primary or secondary amputations in people with complex lower limb injuries. Conclusion. GHOISS is highly accurate in predicting success of limb salvage, and can inform management and predict secondary outcomes. However, there is a need for high-quality multicentre trials to confirm these findings and investigate the effectiveness of the score in children, and in predicting secondary amputations.

Aims. To systematically review the efficacy of split tendon transfer surgery on gait-related outcomes for children and adolescents with cerebral palsy (CP) and spastic equinovarus foot deformity. Methods. Five databases (CENTRAL, CINAHL, PubMed, Embase, Web of Science) were systematically screened for studies investigating split tibialis anterior or split tibialis posterior tendon transfer for spastic equinovarus foot deformity, with gait-related outcomes (published pre-September 2022). Study quality and evidence were assessed using the Methodological Index for Non-Randomized Studies, the Risk of Bias In Non-Randomized Studies of Interventions, and the Grading of Recommendations Assessment, Development and Evaluation. Results. Overall, 17 studies (566 feet) were included: 13 studies used clinical grading criteria to report a postoperative ‘success’ of 87% (75% to 100%), 14 reported on orthotic use with 88% reduced postoperative use, and one study reported on ankle kinematics improvements. Ten studies reported post-surgical complications at a rate of 11/390 feet (2.8%), but 84 feet (14.8%) had recurrent varus (68 feet, 12%) or occurrence of valgus (16 feet, 2.8%). Only one study included a patient-reported outcome measure (pain). Conclusion. Split tendon transfers are an effective treatment for children and youth with CP and spastic equinovarus foot deformities. Clinical data presented can be used for future study designs; a more standardized functional and patient-focused approach to evaluating outcomes of surgical intervention of gait may be warranted.

Emerging evidence suggests preoperative opioid use may increase the risk of negative outcomes following orthopedic procedures. This systematic review evaluated the impact of preoperative opioid use in patients undergoing shoulder surgery with respect to preoperative clinical outcomes, postoperative complications, and postoperative dependence on opioids. EMBASE, MEDLINE, CENTRAL, and CINAHL were searched from inception to April, 2021 for studies reporting preoperative opioid use and its effect on postoperative outcomes or opioid use. The search, data extraction and methodologic assessment were performed in duplicate for all included studies. Twenty-one studies with a total of 257,301 patients were included in the final synthesis. Of which, 17 were level III evidence. Of those, 51.5% of the patients reported pre-operative opioid use. Fourteen studies (66.7%) reported a higher likelihood of opioid use at follow-up among those used opioids preoperatively compared to preoperative opioid-naïve patients. Eight studies (38.1%) showed lower functional measurements and range of motion in opioid group compared to the non-opioid group post-operatively. Preoperative opioid use in patients undergoing shoulder surgeries is associated with lower functional scores and post-operative range of motion. Most concerning is preoperative opioid use may predict increased post-operative opioid requirements and potential for misuse in patients

Abstract. Purpose. Recently several authors have suggested a correlation between posterior tibial slope (PTS) and sagittal stability of the knee. However, there is a lack of consensus in the literature relating to measurement, normal values and important values to guide treatment. We performed a systematic literature review looking at PTS and cruciate ligament surgery. Our aim was to define a gold standard measurement technique, determine normal ranges and important values for consideration during cruciate ligament surgery. Methods. Electronic searches of MEDLINE (PubMed), CINAHL, Cochrane, Embase, ScienceDirect, and NICE in June 2020 were completed. Inclusion criteria were original studies in peer-reviewed English language journals. A quality assessment of included studies was completed using the Methodological Index for Non-Randomized Studies (MINORS) Criteria. Results. Two-hundred and twenty-one papers were identified; following exclusions 34 papers were included for data collection. The mean MINORS score for non-comparative studies was 13.8 and for comparative studies 20.4, both indicating fair to good quality studies. A large variation in PTS measurement technique was identified, resulting in a wide range of values reported. In addition, there appears to be significant variation between different races, ages and genders. Conclusion. We demonstrated a lack of consensus in the literature relating to various facets of PTS. Cautiously, we suggest normal ranges of 6–12º using the proximal tibia axis at 5 and 15cms below the joint. Potentially 12º is an important cute-off for slope reducing osteotomy as an adjunct to revision ACL reconstruction

There is an evolving body of evidence that demonstrates the role of epigenetic mechanisms, such as DNA-methylation in the pathogenesis of OA. This systematic review aims to summarize the current evidence of DNA methylation and its influence on the pathogenesis of OA. A pre-defined protocol in alignment with the PRISMA guidelines was employed to systematically review eight bibliographic databases, to identify associations between DNA-methylation of articular chondrocytes and osteoarthritis. A search of Medline (Ovid), Embase, Web-of-Science, Scopus, PubMed, Cinahl (EBSCOhost), Cochrane Central and Google Scholar was performed between 1st January 2015 to 31st January 2021. Data extraction was performed by two independent reviewers. During the observation period, we identified 15 gene specific studies and 24 genome wide methylation analyses. The gene specific studies mostly focused on the expression of pro-inflammatory markers, such as IL8 and MMP13 which are overexpressed in OA chondrocytes. DNA hypomethylation in the promoter region resulted in overexpression, whereas hypermethylation was seen in non-OA chondrocytes. Others reported on the association between OA risk genes and the DNA methylation pattern close to RUNX2, which is an important OA signal. The genome wide methylation studies reported mostly on differentially methylated regions comparing OA chondrocytes and non-OA chondrocytes. Clustering of the regions identified genes that are involved in skeletal morphogenesis and development. Differentially methylated regions were seen in hip OA and knee OA chondrocytes, and even within different regions of an OA affected knee joint, differentially methylated regions were identified depending on the disease stage. This systematic review demonstrates the growing evidence of epigenetic mechanisms, such as DNA methylation, in the pathogenesis of OA. In recent years, there has been a focus on the interplay between OA risk genes and DNA methylation changes which revealed a reactivation of genes responsible for endochondral ossification during development. These are important findings and may help to identify eventual future therapeutic targets. However, the current body of literature is mostly showing the differences in DNA methylation of OA chondrocytes and non-OA chondrocytes, but a true longitudinal analysis demonstrating the DNA methylation changes actually happening is still not available

Acetabular retroversion (ARV) is a cause of femoroacetabular impingement leading to hip pain and reduced range of motion. We aimed to describe the radiological criteria used for diagnosing ARV in the literature and report on the outcomes of periacetabular osteotomy (PAO) and hip arthroscopy (HA) in its management. A systematic review using PRISMA guidelines was conducted on the MEDLINE, CINAHL, EMBASE, COCHRANE database in December 2022. English-language studies reporting outcomes of PAO, or open or arthroscopic interventions for ARV were included. From an initial 4203 studies, 21 non-randomised studies met the inclusion criteria. Eleven studies evaluated HA for ARV, with average follow-up ranging from 1 to 5 years, for a cumulative number of 996 patients. Only 3/11 studies identified ARV using AP standardized pelvic radiographs. The most frequent signs describing ARV identified were: Ischial Spine Sign (98% of patients), Posterior Wall Sign (PWS, 94%) and Crossover Sign (COS, 64%); with mean Acetabular Retroversion Index (ARI) ranging from 33% to 35%. 39% of HA patients had all three radiographic signs. Clinically significant outcomes were reached by 33–78% of patients. Eight studies evaluated PAO for ARV, with a follow-up ranging from 2 to 10 years, for a cumulative number of 379 patients. Five of the eight studies identified ARV using standardized radiographs. ISS, COS and PWS were positive in 54%, 97% and 81% of patients, respectively with 52% of PAO patients having all three radiographic signs. Mean ARI ranged from 36–41%. Clinically significant results were reported in 71%–78% of patients. The diagnostic criteria for ARV is poorly defined in the literature, and the quality of evidence is low. Studies on HA are more likely to have used lenient diagnostic criteria. It remains difficult to recommend which cases maybe more suitable for treatment by HA rather than PAO

Purpose and background. Work-related musculoskeletal disorders, particularly back pain, are a significant issue for healthcare workers, with patient handling being the most frequently reported risk factor. Patient handling is often performed without assistive devices or equipment, which can cause healthcare staff to maintain awkward postures or experience high loads. This review aimed to comprehensively map the literature surrounding manual patient handling (without assistive devices) by healthcare practitioners to identify the current evidence-base on moving and handling of patients and explore what primary research had been conducted. Methods and results. JBI methodology for scoping reviews and an a priori registered protocol (DOI 10.17605/OSF.IO/8PR7A) was followed and AMED, CINAHL, MEDLINE, SPORTDiscus and EMBASE databases were searched. Literature published in English between 2002 and 2021 was included. Forty-nine records were included: 36 primary research studies, 1 systematic review and 12 ‘other’ including narrative and government reports. Primary research predominantly used observational cross-sectional designs (n = 21 studies). Most studies took place in hospitals (n = 13) and laboratories (n = 12). Nurses formed the largest population group (n = 13), with very little research on physiotherapists and other allied health professionals. Conclusion. This scoping review comprehensively reviewed the available literature in the area. Most of the included primary research was observational. Nurses were often investigated in hospitals and laboratories. Qualitative research investigating moving and handling and further biomechanical investigation into therapeutic handling by healthcare staff were identified as areas for further research. Conflicts of interest. None. Sources of funding. None. This work has been published in Physiotherapy: Johnson, K., Swinton, P., Pavlova, A. and Cooper, K., 2023.

Background. Clinical guidelines recommend epidural steroid injection (ESI) as a treatment option for severe disc-related sciatica, but there is considerable uncertainty about its effectiveness. Currently, we know very little about factors that might be associated with good or poor outcomes from ESI. The aim of this systematic review was to synthesize and appraise the evidence investigating prognostic factors associated with outcomes following ESI for patients with imaging confirmed disc-related sciatica. Methods. The search strategy involved the electronic databases Medline, Embase, CINAHL Plus, PsycINFO and reference lists of eligible studies. Selected papers were quality appraised independently by two reviewers using the Quality in Prognosis Studies (QUIPS) tool. Between study heterogeneity precluded statistical pooling of results. Results. 2726 citations were identified; 11 studies were eligible. Overall study quality was low with all judged to have moderate or high risk of bias. Forty-five prognostic factors were identified but were measured inconsistently. The most commonly assessed prognostic factors were related to pain and function (n=7 studies), imaging features (n=6 studies), health and lifestyle (n=5 studies), patient demographics (n=4 studies) and clinical assessment findings (n=4 studies). No prognostic factor was found to be consistently associated with outcomes following ESI. Most studies found no association or results that conflicted with other studies. Conclusions. There is little, and low quality, evidence to guide practice in terms of factors that predict outcomes in patients following ESI for disc-related sciatica. The results can help inform some of the decisions about potential prognostic factors that should be assessed in future well-designed prospective cohort studies. Conflicts of interest: No conflicts of interest.

Though retear rates following rotator cuff repair are well established, we set out to review current literature to determine when early retears occurred (defined as <12m following surgery), and examine which pre- and post-operative variables might affect outcome. Pubmed, Medline, and CINAHL were searched for literature published from 2011 to 2021 using specific search terms. The inclusion criteria were studies reporting retear rates within 12 months of initial surgical repair. Exclusionary criteria were studies that included partial thickness tears, and studies that did not use imaging modalities within 12 months to assess for retears. PRISMA guidelines were followed, identifying a total of 10 papers. A combined total of 3372 shoulders included (Mean age 56 −67 years). The most common modality used to identify early retears were ultrasound scan and MRI. 6 of the 10 studies completed imaging at 0-3 months, 6 studies imaged at 3-6 months and 6 studies imaged at 6-12 months. Across all studies, there was a 17% early retear rate (574 patients). Of these, 13% occurred by 3 months, whilst the peak for retears occurred at 3-6 months (82%) and 5% occurred at 6-12 months. The risk of retear was higher in larger tears and extensive tendon degeneration. All studies apart from one documented a return to work/sport at 6 months post-operatively. Postoperative rehabilitation does not appear to alter retear rate, although data is limited with only 1 of 10 studies allowing active range of movement before 6 weeks. Retorn tendons had poorer functional outcomes compared to intact tendons at 12m following initial repair. The majority of early retears occur at 3-6 months and this time period should be prioritised both in rehabilitation protocols and future research. Age, tear size, and tendon degeneration were found to influence likelihood of early retears

An international Consensus Group has by a Delphi approach identified the topic of host factors affecting pin site infection to be one of the top 10 priorities in external fixator management. The aim of this study was to report the frequency of studies reporting on specific host factors as a significant association with pin site infection. Host factors to be assessed was: age, smoking, BMI and any comorbidity, diabetes, in particular. The intention was an ethological review, data was extracted if feasible, however no meta-analysis was performed. A systematic literature search was performed according to the PRISMA-guidelines. The protocol was registered before data extraction in PROSPERO. The search string was based on the PICO criterias. A logic grid with key concept and index terms was made. A search string was built assisted by a librarian. The literature search was executed in three electronic bibliographic databases, including Embase MEDLINE (1111 hits) and CINAHL (2066 hits) via Ovid and Cochrane Library CENTRAL (387 hits). Inclusion criteria: external fixation, >1 pin site infection, host factor of interest, peer-reviewed journal. Exclusion criteria: Not written in English, German, Danish, Swedish, or Norwegian, animal or cadaveric studies, location on head, neck, spine, cranium or thorax, editorials or conference abstract. The screening process was done using Covidence. A total of 3564 titles found. 3162 excluded by title and abstract screening. 140 assessed for full text eligibility. 11 studies included for data extraction. The included studies all had a retrospective design. Three identified as case-control studies. Generally the included studies was assessed to have a high risk of bias. A significant associations between pin site infection for following host factors: a) increased HbA1C level in diabetic patients; b) congestive heart failure in diabetic patients; c) less co-morbidity; d) preoperative osteomyelitis was found individually. This systematic literature search identified a surprisingly low number of studies examining for risk of pin site infection and host factors. Thus, this review most of all serves to demonstrate a gap of evidence about correlation between host factors and risk of pin site infection, and further studies are warranted

Abstract. Objective. A common orthopaedic pain found in a wide spectrum of individuals, from young and active to the elderly is anterior knee pain (AKP). It is a multifactorial disorder which is thought to occur through muscular imbalance, overuse, trauma, and structural malalignment. Over time, this can result in cartilage damage and subsequent chondral lesions. Whilst the current gold standard for chondral lesion detection is MRI, it is not a highly sensitive tool, with around 20% of lesions thought to be mis-diagnosed by MRI. Single-photon emission computerised tomography with conventional computer tomography (SPECT/CT) is an emerging technology, which may hold clinical value for the detection of chondral lesions. SPECT/CT may provide valuable diagnostic information for AKP patients who demonstrate absence of structural change on other imaging modalities. This review systematically assessed the value of SPECT/CT as an imaging modality for knee pain, and its ability to diagnose chondral lesions for patients who present with knee pain. Methods. Using PRISMA guidelines, a systematic search was carried out in PubMed, Science Direct, and Web of Knowledge, CINAHL, AMED, Ovid Emcare and Embase. Inclusion criteria consisted of any English language article focusing on the diagnostic value of SPECT/CT for knee chondral lesions and knee pain. Furthermore, animal or cadaver studies, comparator technique other than SPECT/CT or patients with a pathology other than knee chondral lesions were excluded from the study. Relevant articles underwent QUADAS-2 bias assessment. Results. 11,982 manuscripts were identified, and the titles were screened for relevance. Seven studies were selected as being appropriate and were subjected to QUADAS-2 assessment. All 7 articles scored low for bias. Two papers deemed that the ICRS score of chondral lesions at intraoperative assessment correlated with SPECT/CT tracer uptake. Two studies concluded that MRI significantly correlated with SPECT/CT tracer uptake, with some instances whereby SPECT/CT identified more chondral lesions than MRI. Two papers compared bone scintigraphy (BS) to SPECT/CT and concluded that SPECT/CT was not only able to identify more chondral lesions than BS, but also localise and characterise the lesions. Conclusion. Evidence implies that SPECT/CT may be a useful imaging modality for the detection and localisation of cartilage lesions, particularly in discrepant cases whereby there is an absence of lesions on other imaging modalities, or a lack of correspondence with patients’ symptoms. More studies would be of value to confirm the conclusions of this review. Declaration of Interest.

Introduction. External fixators are common surgical orthopaedic treatments for the management of complex fractures and in particular, the use of circular frame fixation within patients requiring limb reconstruction. It is well known that common complications relating to muscle length and patient function without rehabilitation can occur. Despite this there remains a lack of high-quality clinical trials in this area investigating the role of physiotherapy or rehabilitation in the management of these patients. We aim to complete a systematic review of rehabilitation techniques for patients undergoing external fixator treatment for Limb Reconstruction of the lower limb. Materials & Methods. A comprehensive search of AMED, CINAHL, MEDLINE and COCHRANE databases was conducted to identify relevant articles for inclusion, using a search strategy developed in collaboration with a research librarian. Inclusion criteria consisted of adults aged 18 years and over who have experienced leg trauma (open fracture, soft tissue damage), elective leg deformity corrective surgery, bone infection or fracture non-union who have been treated with the use of an external fixator for fixation. Specific exclusion criteria were patients below the age of 18 years old, patients with cancer, treatment of the injury with internal nail, patients who underwent amputation, the use of external fixators for soft tissue contracture management, editorials, comment papers, review papers, conference proceedings and non-English papers. Titles, abstracts, and full texts were screened for suitability by pairs of reviewers according to the inclusion and exclusion criteria using Rayyan QCRI online software. Any conflicts were resolved through discussion with three independent specialist senior reviewers. Following full text screening, references lists of included articles were manually searched to ensure that all relevant studies were identified. Due to lack of evidence, forward searching was also completed for studies included in the review. Data quality was assessed using the mixed methods appraisal tool and the CERT assessment tool was utilised to look at completeness of reporting of exercise interventions. Results. A total number of 832 articles were initially retrieved from our search once duplicate articles removed. After title and abstract screening, 45 articles remained for full text screening. Of these, 11 articles met our inclusion criteria and included for data extraction. Conclusions. We expect high variability of results due to our inclusion criteria and therefore plan to conduct a narrative synthesis to summarise the findings whilst measing against the mixed methods appraisal tool and CERT assessment scores to assess the data quality. We anticipate lower assessment scores within the fewer articles found and therefore poorer-quality data. We currently are in the process of finalising this data extraction. This will be completed ready for submission and potential presentation at the BLRS conference in March 2023

Introduction. Snapping hip syndrome is a common condition affecting 10% of the population. It is due to the advance of the iliotibial band (ITB) over the greater trochanter during lower limb movements and often associated with hip overuse, such as in athletic activities. Management is commonly conservative with physiotherapy or can be surgical to release the ITB. Here we carry out a systematic review into published surgical management and present a case report on an overlooked cause of paediatric snapping hip syndrome. Materials & Methods. A systematic review looking at published surgical management of snapping hip was performed according to PRISMA guidelines. PubMed, MEDLINE, EMBASE, CINAHL and the Cochrane Library databases were searched for “((Snapping hip OR Iliotibial band syndrome OR ITB syndrome) AND (Management OR treatment))”. Adult and paediatric published studies were included as few results were found on paediatric snapping hip alone. Results. 1548 studies were screened by 2 independent reviewers. 8 studies were included with a total of 134 cases, with an age range of 14–71 years. Surgical management ranged from arthroscopic, open or ultrasound guided release of the ITB, as well as gluteal muscle releases. Common outcome measures showed statistically significant improvement pre- and post-operatively in visual analogue pain score (VAPS) and the Harris Hip Score (HHS). VAPS improved from an average of 6.77 to 0.3 (t-test p value <0.0001) and the HHS improved from an average of 62.6 to 89.4 (t-test p value <0.0001). Conclusions. Although good surgical outcomes have been reported, no study has reported on the effect of rotational profile of the lower limbs and snapping hip syndrome. We present the case of a 13-year-old female with snapping hip syndrome and trochanteric pain. Ultrasound confirmed external snapping hip with normal soft tissue morphology and radiographs confirmed no structural abnormalities. Following extensive physiotherapy and little improvement, she presented again aged 17 with concurrent anterior knee pain, patella mal-tracking and an asymmetrical out-toeing gait. CT rotational profile showed 2° of femoral neck retroversion and excessive external tibial torsion of 52°. Consequently, during her gait cycle, in order to correct her increased foot progression angle, the hip has to internally rotate approximately 35–40°, putting the greater trochanter in an anterolateral position in stance phase. This causes the ITB to snap over her abnormally positioned greater trochanter. Therefore, to correct rotational limb alignment, a proximal tibial de-rotation osteotomy was performed with 25° internal rotation correction. Post-operatively the patient recovered well, HHS score improved from 52.5 to 93.75 and her snapping hip has resolved. This study highlights the importance of relevant assessment and investigation of lower limb rotational profile when exploring causes of external snapping hip, especially where ultrasound and radiographs show no significant pathology

Abstract. Objective. There is no specific framework for the clinical management of sports related brachial plexus injuries. Necessarily, rehabilitation is based on injury presentation and clinical diagnostics but it is unclear what the underlying evidence base to inform rehabilitative management. Methods. A systematic review of the literature was undertaken in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We applied the PEO criteria to inform our search strategy to find articles that reported the rehabilitative management of brachial plexus injuries sustained while playing contact sports. An electronic search of Medline, CINAHL, SPORTDiscus and Web of Science from inception to 3rd November 2022 was conducted. MESH terms and Boolean operators were employed. We applied an English language restriction but no other filters. Manual searches of Google Scholar and citation searching of included manuscripts were also completed. All study types were considered for inclusion provided they were published as peer-reviewed primary research articles and contained relevant information. Two investigators independently carried out the searches, screened by title, abstract and full text. Two researchers independently extracted the data from included articles. Data was cross-checked by a third researcher to ensure consistency. To assess internal validity and risk of bias, the Joanna Briggs Institute (JBI) critical appraisal tools were utilised. Results. The search generated 88 articles. Following removal of duplicates, 43 papers were evaluated against the eligibility criteria. Nine were eligible for full text review, with the majority of exclusions being expert opinion articles. Eight case reports were included. One article reported three individuals, resulting in data for ten athletes. The mean age was 19.8 years (±4.09). Injuries occurred in five American football players, two wrestlers, two rugby players, and a basketball player. No two studies applied the same diagnostic terminology and the severity of injury varied widely. Burning pain and altered sensation was the most commonly reported symptom, alongside motor weakness in the upper limb. Clinical presentation and management differed by injury pattern. Traction injuries caused biceps motor weakness and atrophy of the deltoid region, whereas compression injuries led to rotator cuff weakness. In all cases treatment was separated into acute and rehabilitative management phases, however the time frames related to these differed. Acute interventions varied but essentially entailed soft tissue inflammation management. Rehabilitation approaches variously included strengthening of shoulder complex and cervical musculature. Return-to-play criteria was opaque. The methodological quality of the case reports was acceptable. Four met all nine of the JBI evaluation criteria, and a further three met at least 75% of items. Conclusion(s). There is a distinct lack of evidence supporting rehabilitation management of sports related brachial plexus injury. Through systematic review we found only eight reports, representing ten individual case studies. No trials, cohort studies, or even retrospective registry-based studies are available to inform clinical management, which, necessarily, is driven by expert opinion and application of basic rehabilitation principles.

Abstract. Non-operative management of AIS can present practical and psychological challenges, as effective bracing requires a considerable investment of time in adolescence which is a formative point of physical and emotional development. The management team lacks input from the psychological team and thus, it would be prudent for the spinal teams to appreciate and deal with the psychosocial effects associated with bracing. We sought to investigate how bracing as a part of non-operative management of idiopathic scoliosis, is perceived among adolescents. We performed a search of CINAHL, Medline, AMED, PsychARTICLES, Psychology and Behavioral Sciences Collection and PsychINFO databases to identify qualitative research investigating the thoughts, feelings and experiences and attitudes of those undergoing bracing for AIS. Keywords used were (((“adoles∗” OR “young pe∗”) AND “idiopathic scoliosis”) AND “brac∗”) AND (“perce∗” OR “experience∗” OR “perspective∗” OR “attitude∗”). Ten research articles were identified using our search strategy. Only one article addressed our research question specifically. This reported that almost all adolescent patients experienced psychological difficulties during treatment and received most of their support from family and friends rather than health professionals. Our interpretation of the literature on this subject has yielded three recommendations for service providers. First, the policy ought to change to ensure that psycholological support is engrained within the treatment process; second, more information and advice must be given to patients and their families; and third, health professionals should appreciate and directly address in their consultations the psychological difficulties involved in brace wearing and the need for adequate support

Aims. We conducted a systematic review and meta-analysis to compare the mortality, morbidity, and functional outcomes of cemented versus uncemented hemiarthroplasty in the treatment of intracapsular hip fractures, analyzing contemporary and non-contemporary implants separately. Methods. PubMed, Medline, EMBASE, CINAHL, and Cochrane Library were searched to 2 February 2020 for randomized controlled trials (RCTs) comparing the primary outcome, mortality, and secondary outcomes of function, quality of life, reoperation, postoperative complications, perioperative outcomes, pain, and length of hospital stay. Relative risks (RRs) and mean differences (with 95% confidence intervals (CIs)) were used as summary association measures. Results. A total of 18 studies corresponding to 16 non-overlapping RCTs with a total of 2,819 intracapsular hip fractures were included. Comparing contemporary cemented versus uncemented hemiarthroplasty, RRs (95% CIs) for mortality were 1.32 (0.44 to 3.99) perioperatively, 1.01 (0.48 to 2.10) at 30 days, and 0.90 (0.71 to 1.15) at one year. The use of contemporary cemented hemiarthroplasty reduced the risk of intra- and postoperative periprosthetic fracture. There were no significant differences in the risk of other complications, function, pain, and quality of life. There were no significant differences in perioperative outcomes except for increases in operating time and overall anaesthesia for contemporary cemented hemiarthroplasty with mean differences (95% CIs) of 6.67 (2.65 to 10.68) and 4.90 (2.02 to 7.78) minutes, respectively. The morbidity and mortality outcomes were not significantly different between non-contemporary cemented and uncemented hemiarthroplasty. Conclusion. There are no differences in the risk of mortality when comparing the use of contemporary cemented with uncemented hemiarthroplasty in the management of intracapsular hip fractures. Contemporary cemented hemiarthroplasty is associated with a substantially lower risk of intraoperative and periprosthetic fractures. Cite this article: Bone Joint J 2020;102-B(9):1113–1121

Aims. Gender bias and sexual discrimination (GBSD) have been widely recognized across a range of fields and are now part of the wider social consciousness. Such conduct can occur in the medical workplace, with detrimental effects on recipients. The aim of this review was to identify the prevalence and impact of GBSD in orthopaedic surgery, and to investigate interventions countering such behaviours. Methods. A systematic review was conducted by searching Medline, EMCARE, CINAHL, PsycINFO, and the Cochrane Library Database in April 2020, and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to which we adhered. Original research papers pertaining to the prevalence and impact of GBSD, or mitigating strategies, within orthopaedics were included for review. Results. Of 570 papers, 27 were eligible for inclusion. These were published between 1998 and 2020. A narrative review was performed in light of the significant heterogeneity displayed by the eligible studies. A total of 13 papers discussed the prevalence of GBSD, while 13 related to the impact of these behaviours, and six discussed mitigating strategies. GBSD was found to be common in the orthopaedic workplace, with all sources showing women to be the subjects. The impact of this includes poor workforce representation, lower salaries, and less career success, including in academia, for women in orthopaedics. Mitigating strategies in the literature are focused on providing female role models, mentors, and educational interventions. Conclusion. GBSD is common in orthopaedic surgery, with a substantial impact on sufferers. A small number of mitigating strategies have been tested but these are limited in their scope. As such, the orthopaedic community is obliged to participate in more thoughtful and proactive strategies that mitigate against GBSD, by improving female recruitment and retention within the specialty.

Abstract. BACKGROUND. The effectiveness of anti-embolic graduated compression stockings (GCSs) has recently been questioned. The aim of this study is to systematically review all the relevant randomised controlled trials published to date. PATIENTS AND METHODS. We systematically reviewed all the randomised controlled trials comparing anti-embolism stockings with no stockings. We searched the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE and CINAHL, Cochrane Musculoskeletal Injuries Group specialized register and the reference lists of articles as well as hand search results. Trials were independently assessed and data for the main outcome measures; deep vein thrombosis (DVT), pulmonary embolism and skin ulceration, were extracted by two reviewers. RESULTS. A total of 26 relevant RCTs involving 8279 participants were systematically reviewed. Theoccurrence of deep vein thrombosis was 306/4159(7.3%) with the stocking to 492/4120(11.9%) without the stockings (RR 0.49, 95% CI 0.39–0.62). The occurrence of pulmonary embolism was also reduced from 1.2% go 0.7% (95% 0.33–0.92). This initial finding was unsound due to the potential underreporting of negative studies and the subsequent changes to clinical practice. For the three large contemporary studies involving 5171 participants, these failed to show any statistically significant reduction in thrombosis, with DVT confirmed in 158(6.1%) participants in those allocated to stocking, as opposed to 171(6.6%) in the control group. CONCLUSION. The current recommendations regarding the use of GCSs need to be reconsidered, as their effectiveness at reducing the occurrence of post-operative DVT is minimal at best, based on the current evidence and clinical practices

Aims. The purpose of this study was to: review the efficacy of the induced membrane technique (IMT), also known as the Masquelet technique; and investigate the relationship between patient factors and technique variations on the outcomes of the IMT. Methods. A systematic search was performed in CINAHL, The Cochrane Library, Embase, Ovid MEDLINE, and PubMed. We included articles from 1 January 1980 to 30 September 2019. Studies with a minimum sample size of five cases, where the IMT was performed primarily in adult patients (≥ 18 years old), in a long bone were included. Multivariate regression models were performed on patient-level data to determine variables associated with nonunion, postoperative infection, and the need for additional procedures. Results. A total of 48 studies were included, with 1,386 cases treated with the IMT. Patients had a mean age of 40.7 years (4 to 88), and the mean defect size was 5.9 cm (0.5 to 26). In total, 82.3% of cases achieved union after the index second stage procedure. The mean time to union was 6.6 months (1.4 to 58.7) after the second stage. Our multivariate analysis of 450 individual patients showed that the odds of developing a nonunion were significantly increased in those with preoperative infection. Patients with tibial defects, and those with larger defects, were at significantly higher odds of developing a postoperative infection. Our analysis also demonstrated a trend towards the inclusion of antibiotics in the cement spacer having a protective effect against the need for additional procedures. Conclusion. The IMT is an effective management strategy for complex segmental bone defects. Standardized reporting of individual patient data or larger prospective trials is required to determine the optimal implementation of this technique. This is the most comprehensive review of the IMT, and the first to compile individual patient data and use regression models to determine predictors of outcomes.

Abstract. Objectives. Achilles tendon ruptures are common in the UK, with data demonstrating a significant rise in incidence over the past years. Chronic Achilles ruptures have been less well defined in literature, and repair techniques vary significantly. A surge in publications reporting various management options for chronic Achilles ruptures has necessitated a review that systematically maps and summarises current evidence regarding treatments and identifies areas for future research. This scoping review aims to improve knowledge of various treatment strategies and their associated outcomes, thereby aiding clinicians in optimising treatment protocols. Methods. The Arksey and O'Malley, Levac and Peters frameworks were used. A computer-based search in PubMed, Embase, Emcare, Cinahl, ISI Web of Science and Scopus was performed for articles reporting the treatment of chronic Achilles ruptures. Two reviewers independently performed title/abstract and full text screening according to a pre-defined selection criteria. Results. A total of 747 articles were identified, of which 73 were finally included. Various management strategies were described with flexor hallucis longus tendon transfer being the most common. The American Orthopaedic Foot and Ankle Society (AOFAS) score was the most commonly reported outcome, but 16 other measures were described within the literatures. All studies comparing pre- and post-operative outcomes reported a significant improvement. 50 studies reported complications, with an overall pooled complication rate of 168/1065 (15.8%). Conclusions. Beneficial results were reported following various techniques, but comparison between these was challenging due to the low-level study designs used and confounding factors including treatment delay and tendon gap size. Further research exploring the efficacy of different techniques is required to facilitate the development of evidenced-based treatment protocols. Such a work would allow for clinicians to better understand the suitability of specific techniques, thereby selecting the optimal management strategy for each individual patient

Introduction and Objective. Several studies have described double and triple femoral neck lengthening osteotomies to correct coxa brevis deformity, however, no overview exists in literature. Our aim was to perform the first systematic review of the outcomes of double and triple femoral neck lengthening. Materials and Methods. After an extensive search in Pubmed, CINAHL and Embase libraries for published articles using the following search strategy: ‘(((proximal femoral deformity) OR hip dysplasia) OR coxa brevis) AND (((femoral neck lengthening) OR double proximal femoral osteotomy) OR triple proximal femoral osteotomy)’, we included studies reporting the results of double and triple femoral neck osteotomies. Clinical and radiological outcomes, and reported complications were extracted. The review process was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Results. After evaluating 456 articles, we included 11 articles reporting 149 osteotomies in 143 patients (31% male, 64% female, 5% unspecified). Mean age of the patients was 20 years (range 7 years to 52 years). Indications were developmental hip dysplasia (51%), Perthes disease (27%), infection (6%), post-trauma (4%), congenital disorders (2%), slipped capital femoral epiphysis (1%), idiopathic (3%) and unknown (6%). The mean limb length discrepancy reduced by 12 mm (0 mm to 40 mm). In total, 65% of 101 positive Trendelenburg sign hips experienced improvement of abductor muscle strength. An 18% (9% to 36%) increase could be found in functional hip scores. Mean increase in articulo-trochanteric distance was 24 mm (10 mm to 34 mm). Five patients older than 30 years at the time of osteotomy and two younger patients with prior hip incongruency had disappointing results and required arthroplasty. In all, 12 complications occurred in 128 osteotomies, in which complications were reported. Conclusions. This first systematic review of double and triple femoral neck lengthening osteotomies shows that favorable outcomes and few complications can be expected in coxa brevis, however, excessive caution is required in older patients with incongruent hips

Aim. Chronic osteomyelitis reflects a progressive inflammatory process of destruction and necrosis affecting bone architecture. It presents a challenge to manage, requiring multi-stage multidisciplinary interventions, and the literature reports a wide variety of treatment strategies. This systematic scoping review aims to map and summarise existing literature on treatment of chronic osteomyelitis of the femur and tibia and investigates the full range of treatments reported in order to enhance the reader's understanding of how to manage this complex condition. Method. A comprehensive computer-based search was conducted in PubMed, EMBASE, MEDLINE, Emcare and CINAHL for articles reporting treatment of chronic tibial/femoral osteomyelitis. Two reviewers independently performed a two-stage title/abstract and full-text screening, followed by data collection. Studies were included if they described any treatment strategy including at least one surgical intervention. Key information extracted included causative pathogens, treatment protocol and outcome i.e. both success rate, defined as remission achieved following initial treatment with no recurrence during followup, and recurrence rate. Results. A total of 1230 articles were identified, and 40 articles (2529 patients) ultimately included. Although a wide variety of treatment protocols are reported, all revolve around three key principles: removal of infected tissue, dead space management and antibiotic therapy. Variations are evident when considering use of extensive versus more conservative debridement techniques, and delivery and regime of antibiotic therapy, e.g. whether to use one of, or both systemic and local delivery. The majority (84.5%) of patients presented with stage III or IV disease according to the Cierny-Mader classification and staphylococcus aureus was the most commonly isolated organism. Although there is heterogeneity across studies in reporting outcomes, with only 29 studies reporting success rate as defined in this review, 25 (86.2%) of these reported a success rate of at least 80%. Conclusions. It is difficult to identify the optimal treatment strategy when reporting of outcomes is not standardised across studies, even in the context of similar techniques being used. Success rates across studies may also vary depending on patient demographics, comorbidities, severity, type and number of causative pathogens and follow-up length. It is now essential to identify specific patient and treatment related factors that may affect clinical outcomes. Given the current dominance of case series in the literature, there is a need for randomised controlled trials to yield further information that could aid future efficient management

Introduction. Patient reported outcome measures (PROMs) are used to understand the impact of lower limb reconstruction on patient's quality of life (QOL). Existing measures have not been developed to specifically capture patient experiences amongst adults with lower limb conditions that require reconstruction surgery. This systematic review of qualitative studies (qualitative evidence synthesis) aimed to identify what is important to these patients. Materials and Methods. MEDLINE, Embase, PsychINFO and Cinahl were searched from inception until November 2020. Studies were included if they employed qualitative research methods, involved patients requiring, undergoing or following lower limb reconstruction and explored patients' experiences of care, treatment, recovery and QOL. Mixed methods/population studies that did not separate the findings from each group and studies not in English were excluded. Included studies were analysed using thematic synthesis. The review followed the methodological framework published by the Cochrane Qualitative and Implementation Methods Group for qualitative evidence syntheses. Results. Nine studies met the inclusion criteria. Thematic synthesis identified two overarching themes:(1) areas of living key to QOL for lower limb reconstruction patients, with sub-themes: pain, daily functioning and lifestyle, identity, income and emotional wellbeing and (2) moving towards a new normal, with sub-themes: support, the ability to adapt and adjust and the ability to move forwards. The impact of lower limb reconstruction on QOL and recovery is complex and is influenced by a range of inter-related factors, which will affect patients to varying degrees depending on individual circumstances. Conclusions. The impact of lower limb reconstruction on patients' QOL is complex, may change over time and is strongly linked to their recovery. This review was conducted as part of the wider ‘PROLLIT' study, which will develop a conceptual framework to identify what outcomes are important to patients and should be included in a PROM. We will then map our conceptual framework onto existing PROMS to establish whether our identified factors are captured by current PROMS. Depending on the outcome of this work, a new PROM for patients following lower limb reconstruction may be developed

Abstract. Objectives. Modular dual-mobility (MDM) constructs are used to reduce dislocation rates after total hip replacement (THR). They combine the advantages of dual mobility with the option of supplementary acetabular screw fixation in complex revision surgery. However, there are concerns about adverse reaction to metal debris (ARMD) as a result of fretting corrosion between the metal liner and shell. Methods. The aim of this systematic review was to find and review all relevant studies to establish the outcomes and risks associated with MDM hip replacement. All articles on MDM THRs in the Medline, EMBASE, CINAHL, Cochrane Library, and Prospero databases were searched. A total of 14 articles were included. A random intercept logistic regression model was used for meta-analysis, giving estimated mean values. Results. There were 6 cases of ARMD out of 1312 total. Estimated median incidence of ARMD from meta-analysis was 0.3% (95% CI 0.1 – 1.4%). Mean postoperative serum Cobalt was 0.81 μg/L (95% CI 0.33 – 1.29 μg/L), and Chromium was 0.77 μg/L (95% 0.35 – 1.19 μg/L), from 279 cases in 7 studies. Estimated median incidence of a serum cobalt or chromium ion measurement ≥1 μg/L was 7.9% (95% CI 3.5 – 16.8%), and ≥7 μg/L was 1.8% (95% CI 0.7 – 4.2%). Conclusions. ARMD is a rare but significant complication following total hip replacement using a MDM construct. Its incidence appears higher than that reported in non-metal-on-metal (MoM) hip replacements but lower than that of MoM hip replacements. MDM hip replacements are associated with raised serum metal ion levels postoperatively, but there was no correlation with worse clinical hip function within studies. Studies were poor quality and at high risk of confounding. Pending further work, MDM constructs should be used with caution, reserved for select cases at particularly high risk of dislocation.

Intro. Calcium sulphate (CS) is a recent alternative for antibiotic elution in infected bones and joints. The purpose of this study is to evaluate the use of antibiotic impregnated calcium sulphate (AICS) beads in the management of infected tibia and femur, with regards to patient outcomes and complication rates (including reinfection rate, remission rate and union rate). Methods. Searches of AMED, CINAHL, EMBASE, EMCARE, Medline, PubMed and Google Scholar were conducted in June 2020, with the mesh terms: “Calcium sulphate beads” or “Calcium sulfate beads” or “antibiotic beads” or “Stimulan” AND “Bone infection” or “Osteomyelitis” or “Debridement” AND “Tibia” or “Femur”. Risk of bias was assessed using the Risk of Bias in Non-randomised Studies of interventions (ROBINS-i) tool, and quality assessed via the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) criteria. Results. Out of 105 relevant papers, 11 met the inclusion criteria for data extraction. Total infection recurrence rate was 6.8% (range 3.2 – 11.9%, n = 295), which was significantly lower (p < 0.001) than that of polymethylmethacrylate (PMMA; 19.6%, n = 163). Complication rates varied. The main issue regarding AICS use was wound drainage (7.9 – 33.3%), which was considerably higher in studies involving treatment of the tibia only. Studies using PMMA did not experience this issue, but there were a few incidences of superficial pin tract infection following surgery. Conclusions. AICS was consistently effective at infection eradication, despite variation in causative organism and location of bead placement. Additionally, PMMA has many inconvenient properties. AICS is therefore an attractive alternative as an adjunct in treatment of infected tibia and femur. Wound drainage rate varied and was higher in studies regarding tibial cases alone

Persistent post-surgical pain affects 10%-80% of individuals after common operations, and is more common among patients with psychological factors such as depression, anxiety, or catastrophising. We conducted a systematic review and meta-analysis of randomised, controlled trials to evaluate the efficacy of perioperative psychotherapy for persistent postsurgical pain and physical impairment. We searched Medline, PsycINFO, CINAHL, and the Cochrane Central Registry of Controlled Trials to identify relevant RCTs, in any language, from inception of each database to September 1, 2016. Paired independent reviewers identified studies, extracted data, and assessed risk of bias. We pooled treatment effects of perioperative psychotherapy on similar outcomes across eligible trials, focusing on intention-to-treat analysis. We used random effects models to perform all meta-analyses. The Grading of Recommendations, Assessment, Development and Evaluation system was used to assess the quality of evidence. Our search found 15 trials (2220 patients) that were eligible for review. For both persistent post-surgical pain and physical impairment, perioperative education was ineffective, while active psychotherapy suggested a benefit (test of interaction P=0.01 for both outcomes). Moderate quality evidence showed that active perioperative psychotherapy (cognitive-behaviour therapy, relaxation therapy, or both) significantly reduced persistent post-surgical pain [weighted mean difference (WMD) −1.06 cm on a 10 cm visual analogue scale for pain, 95% confidence interval (CI) −1.56 to −0.55 cm, risk difference (RD) for achieving no more than mild pain (3 cm or less) 14%, 95% CI 8–21%] and physical impairment [WMD −9.87% on the 0–100% Oswestry Disability Index, 95% CI −13.42 to −6.32%, RD for achieving no more than mild disability (20% or less) 21%, 95% CI 13–29%]. Perioperative cognitive behavioural therapy and relaxation therapy are effective for reducing persistent pain and physical impairment after surgery. High quality evidence shows no significant effects of perioperative education or psychological support on persistent post-surgical pain or physical impairment compared with usual care. Future studies should explore targeted psychotherapy for surgical patients at higher risk for poor outcome

Rotator cuff injuries represent a significant burden to the health care system, affecting more than 30% of the population over the age of sixty. Despite the advanced surgical techniques that are available, poor results are sometimes seen in a subset of patients receiving surgical treatment for their rotator cuff disease. The reasons for this failure of treatment remain unclear, particularly if the surgery was ‘technically’ successful. An increasing body of evidence has demonstrated a strong correlation between pre-operative psychological factors and functional outcome following several orthopaedic procedures. This association, however, has not been fully demonstrated or effectively investigated in the context of rotator cuff treatment. The main objective for this study was to conduct a systematic review to determine the impact of psychosocial factors on the outcome of treatment in patients with rotator cuff disease. A systematic search was conducted of Medline, CINAHL, and PsychInfo databases for articles published from database inception until September 2018. The titles and abstracts were screened for all of the studies obtained from the initial search. Inclusion and exclusion criteria were applied, and a full text review was conducted on those studies meeting the eligibility criteria. A total of 1252 studies were identified. Following removal of duplicates and application of the inclusion and exclusion criteria, 46 studies underwent a full-text review. Ten studies were included in the final analysis. A total of 1,206 patients, with a mean follow-up of 13 months, were included. Three studies examined patient expectations prior to treatment. All three found that higher expectations prior to treatment led to a significantly improved outcome following both operative and non-operative treatment. Three studies assessed the association between pre-operative general psychological measures and post-operative pain and function. All three studies found patients with worse pre-operative general psychological scores demonstrated increased post-operative pain. Two of the studies also found a negative association with post-operative function, while one of the studies found no association with post-operative function. Three studies assessed the impact of pre-operative anxiety and depression on outcomes following surgical treatment of rotator cuff disease. Only one of the studies found a negative association with post-operative pain and function. The remaining two studies found no association between anxiety or depression and any outcomes following surgery. Finally, one study examined the impact of general distress on outcomes following the surgical treatment of rotator cuff disease and found no association with post-operative levels of pain or function. The results of this systematic review indicate that there is somewhat conflicting and contradictory evidence within the literature. Overall, however, there does appear to be an association between pre-operative psychological factors and post-operative function and pain, in that higher levels of pre-operative psychological dysfunction are predictive of poorer function and increased pain following the treatment of rotator cuff disease

Aims. The aim of this study was to assess the current available evidence about when patients might resume driving after elective, primary total hip (THA) or total knee arthroplasty (TKA) undertaken for osteoarthritis (OA). Materials and Methods. In February 2016, EMBASE, MEDLINE, Web of Science, Scopus, Cochrane, PubMed Publisher, CINAHL, EBSCO and Google Scholar were searched for clinical studies reporting on ‘THA’, ‘TKA’, ‘car driving’, ‘reaction time’ and ‘brake response time’. Two researchers (CAV and JJT) independently screened the titles and abstracts for eligibility and assessed the risk of bias. Both fixed and random effects were used to pool data and calculate mean differences (MD) and 95% confidence intervals (CI) between pre- and post-operative total brake response time (TBRT). Results. A total of 19 studies were included. The assessment of the risk of bias showed that one study was at high risk, six studies at moderate risk and 12 studies at low risk. Meta-analysis of TBRT showed a MD decrease of 25.54 ms (95% CI -32.02 to 83.09) two weeks after right-sided THA, and of 18.19 ms (95% CI -6.13 to 42.50) four weeks after a right-sided TKA, when compared with the pre-operative value. Conclusion. The TBRT returned to baseline two weeks after a right-sided THA and four weeks after a right-sided TKA. These results may serve as guidelines for orthopaedic surgeons when advising patients when to resume driving. However, the advice should be individualised.

Objectives. The objective of this study was to assess all evidence comparing the Thompson monoblock hemiarthroplasty with modular unipolar implants for patients requiring hemiarthroplasty of the hip with respect to mortality and complications. Methods. A literature search was performed to identify all relevant literature. The population consisted of patients undergoing hemiarthroplasty of the hip for fracture. The intervention was hemiarthroplasty of the hip with a comparison between Thompson and modular unipolar prostheses. Pubmed, Embase, CINAHL, Web of Science, PROSPERO and the Cochrane Central Register of Controlled Trials. The study designs included were randomised controlled trials (RCTs), well designed case control studies and retrospective or prospective cohort studies. Studies available in any language, published at any time until September 2015 were considered. Studies were included if they contained mortality or complications. Results. The initial literature search identified 4757 items for examination. Four papers were included in the final review. The pooled odds ratio for mortality was 1.3 (95% confidence Interval 0.78 to 2.46) favouring modular designs. The pooled odds ratio for post-operative complications was 1.1 (95% CI 0.79 to 1.55) favouring modular designs. Outcomes were reported at 12 or six months. These papers all contained potential sources of bias and significant clinical heterogeneity. Conclusion. The current evidence comparing monoblock versus modular implants in patients undergoing hemiarthroplasty is weak. Confidence intervals around the pooled odds ratios are broad and incorporate a value of one. Direct comparison of outcomes from these papers is fraught with difficulty and, as such, may well be misleading. A well designed randomised controlled trial would be helpful to inform evidence-based implant selection. Cite this article: A. L. Sims, A. J. Farrier, M. R. Reed, T. A. Sheldon.

Background and Purpose. Non-specific chronic low back pain (NSCLBP) poses a significant disability and economic burden worldwide. Fear avoidance is suggested to contribute to its chronicity and reduced treatment effect. National guidelines recommend exercise as a component of multidisciplinary rehabilitation but its interaction with fear avoidance is ambiguous. This systematic review examined the effect of exercise-based interventions (EBIs) on fear avoidance NSCLBP. Methods and Results. RCTs comparing EBIs to usual care in adults with NSCLBP were included. A systematic search of CINAHL, Medline, EMBASE, Web of Science, Scopus and Cochrane Library (up to January 2019) revealed 10 eligible trials. Following risk of bias assessment, 6 studies were included for data extraction and narrative synthesis. EBIs were not found superior to usual care in reducing fear avoidance at any follow-up. There was evidence that reducing fear avoidance is probably not the mechanism through which EBIs affect pain and disability. In adherent patients, EBIs did not result in greater clinically relevant improvements in pain or disability than usual care, in the short- or intermediate-term. Conclusion. Addition of EBIs as part of multidisciplinary rehabilitation is not more beneficial than that of usual care in reducing fear avoidance in NSCLBP patients. However, the findings of this review are based on heterogenous studies presenting with methodological limitations. Further high-quality research is required to examine the review's findings and investigate current physiotherapy management of fear avoidance in NSCLBP. No conflicts of interest. No funding obtained

Background. About 85% of the patients with low back pain seeking medical care have nonspecific low back pain (NsLBP), implying that no definitive cause can be identified. Many pain conditions are linked with elevated serum levels of (pro-)inflammatory biomarkers. Purpose. To unravel the etiology and get better insight in the prognosis of NsLBP, the aim of this study was to assess the association between (pro-)inflammatory biomarkers and the presence and severity of NsLBP. Methods. A systematic literature search was made in Embase, Medline, Cinahl, Web-of-science, and Google scholar up to January 19th 2017. Included were studies reporting on patients >18 years with NsLBP, in which one or more pro-inflammatory biomarkers were measured in blood plasma. The methodological quality of the included studies was assessed using the Newcastle Ottawa Scale (NOS). A best-evidence synthesis was used to summarize the results from the individual studies. Results. Included were 10 studies which assessed 4 different (pro-)inflammatory biomarkers. For the association between the presence of NsLBP and C-reactive protein (CRP), interleukin 6 (IL-6) and tumor necrosis factor (TNF)-α limited, conflicting and moderate evidence, respectively, was found. For the association between the severity of NsLBP and CRP and IL-6, moderate evidence was found. For the association between the severity of NsLBP and TNF-α and RANTES conflicting and limited evidence, respectively, was found. Conclusions. This study found moderate evidence for i) a positive association between the (pro-)inflammatory biomarkers CRP and IL-6 and the severity of NsLBP, and ii) a positive association between TNF-α and the presence of NsLBP. No conflicts of interest. No funding obtained

Acute metatarsal fractures are a common extremity injury. While surgery may be recommended to reduce the risk of nonunion or symptomatic malunion, most fractures are treated with nonoperative management. However, there is significant variability between practitioners with no consensus among clinicians on the most effective nonoperative protocol, despite how common the form of treatment. This systematic review identified published conservative treatment modalities for acute metatarsal fractures and compares their non-union rate, chronic pain, and length of recovery, with the objective of identifying a best-practices algorithm. Searches of CINAHL, EMBASE, MEDLINE, and CENTRAL identified clinical studies, level IV or greater in LOE, addressing non-operative management strategies for metatarsal fractures. Two reviewers independently screened the titles, abstracts, and full texts, extracting data from eligible studies. Reported outcome measures and complications were descriptively analyzed. Studies were excluded if a rehabilitation program outlining length of immobilization, weight-bearing and/or strengthening approaches was not reported. A total of 12 studies (8 RCTs and 4 PCs), from the 2411 studies that were eligible for title screening, satisfied inclusion criteria. They comprised a total of 610 patients with acute metatarsal fractures, with a mean age of 40.2 years (range, 15 – 82). There were 6 studies that investigated avulsion fractures, 2 studies on true Jones fractures, and 4 studies with mixed fracture types. Studies assessed a variety of treatment modalities including: WB and NWB casts, elasticated support bandages, hard-sole shoes, plaster slippers, metatarsal shoe casts, and air cast boots. Most studies investigated the outcomes of NWB casts and elasticated support bandages. The NWB short leg cast had no reported non-unions, delayed-unions, or refractures for avulsion fractures. In true Jones fractures, there was an average non-union rate of 23.6% (range, 5.6 – 27.8%), delayed-union rate of 11.8% (range, 5.6 – 18.8%), and refracture rate of 3% (range, 0 – 5.6%). Overall, the average AOFAS score was 87.2 (range, 84 – 91.7) and the average VAS score was 83.7 (range, 75 – 93). The elasticated support bandage had an average non-union rate of 3.4% (range, 0 – 12%), and delayed-union rate of 3.8% for acute avulsion fractures, with no reported refractures. No included study arm investigated outcomes of elasticated support bandages for the true Jones fracture. The average AOFAS score for elasticated support bandages was 93.5 (range, 90 – 100). The average VAS score was 88.9 (range, 90 – 100). Most acute metatarsal fractures heal well, with good-to-excellent functional outcomes and moderate-to-high patient satisfaction. Conservative strategies for avulsion fractures are highly successful and based on this data the authors recommend patients undergo a schedule that involves 3 – 4 weeks in an elasticated support bandage, short leg cast, or equivalent, and WB thereafter as tolerated, with return-to-activity after clinical union. Despite poorer conservative outcomes for true Jones fractures, patients should undergo 8 weeks in a NWB short leg cast, followed by a walking cast or hard-sole shoe for an additional 4 – 6 weeks, or until clinical union. However, surgical consultation is recommended

Objectives. Patient-reported outcome measures (PROMs) are often used to evaluate the outcome of treatment in patients with distal radial fractures. Which PROM to select is often based on assessment of measurement properties, such as validity and reliability. Measurement properties are assessed in clinimetric studies, and results are often reviewed without considering the methodological quality of these studies. Our aim was to systematically review the methodological quality of clinimetric studies that evaluated measurement properties of PROMs used in patients with distal radial fractures, and to make recommendations for the selection of PROMs based on the level of evidence of each individual measurement property. Methods. A systematic literature search was performed in PubMed, EMbase, CINAHL and PsycINFO databases to identify relevant clinimetric studies. Two reviewers independently assessed the methodological quality of the studies on measurement properties, using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist. Level of evidence (strong / moderate / limited / lacking) for each measurement property per PROM was determined by combining the methodological quality and the results of the different clinimetric studies. Results. In all, 19 out of 1508 identified unique studies were included, in which 12 PROMs were rated. The Patient-rated wrist evaluation (PRWE) and the Disabilities of Arm, Shoulder and Hand questionnaire (DASH) were evaluated on most measurement properties. The evidence for the PRWE is moderate that its reliability, validity (content and hypothesis testing), and responsiveness are good. The evidence is limited that its internal consistency and cross-cultural validity are good, and its measurement error is acceptable. There is no evidence for its structural and criterion validity. The evidence for the DASH is moderate that its responsiveness is good. The evidence is limited that its reliability and the validity on hypothesis testing are good. There is no evidence for the other measurement properties. Conclusion. According to this systematic review, there is, at best, moderate evidence that the responsiveness of the PRWE and DASH are good, as are the reliability and validity of the PRWE. We recommend these PROMs in clinical studies in patients with distal radial fractures; however, more clinimetric studies of higher methodological quality are needed to adequately determine the other measurement properties.

Background and aims. The EU-funded Back-UP project aims to develop a cloud computer platform to guide the treatment of low back and neck pain (LBNP) in first contact care and early rehabilitation. In order to identify evidence-based treatment options that can be recommended and are accessible to people with LBNP across Europe, we conducted a systematic review of recently published guidelines. Methods. Electronic databases, including Medline, Embase, CINAHL, PsycINFO, HMIC, Epistemonikos, PEDro, TRIP, NICE, SIGN, WHO, Guidelines International Network (G-I-N) and DynaMed Plus were searched. We searched for guidelines published by European health professional or guideline development organisations since 2013, focusing on the primary care management of adult patients presenting with back or neck pain (including whiplash associated symptoms, radicular pain, and pregnancy-related LBP). The AGREE-II tool was used to assess the quality of guideline development and reporting. Results. Searches generated 3098 unique citations that were screened for eligibility. A total of 189 full-texts were retrieved, and 18 guidelines were included in the review (from the UK, Germany, France, Italy, Denmark, Poland, Belgium, and the Netherlands). Data extraction showed considerable variation in guideline development processes, especially regarding the methods used for identifying, appraising, and synthesising evidence, and for formulating, agreeing, and grading recommendations. Conclusions. Recommendations for the management of LBNP cover a wide range of treatment options, with self-management advice, analgesics, and exercise proposed as core treatments by most guidelines. A narrative synthesis, taking into account consistency, strength, and quality of guideline recommendations, will be presented. No conflicts of interest.

Aims. To examine the rates of hamstring graft salvage with arthroscopic debridement of infected anterior cruciate ligament (ACL) reconstruction as reported in the literature and discuss functional outcomes. Materials and Methods. A search was performed without language restriction on PubMed, EMBASE, Ovid, CINAHL and Cochrane Register of Controlled Trials (CENTRAL) databases from their inception to April 2015. We identified 147 infected hamstring grafts across 16 included studies. Meta-analysis was performed using a random-effects model to estimate the overall graft salvage rate, incorporating two different definitions of graft salvage. Results. The graft salvage rate was 86% (95% confidence intervals (CI) 73% to 93%; heterogeneity: tau. 2. = 1.047, I. 2. = 40.51%, Q = 25.2, df = 15, p < 0.001), excluding ACL re-ruptures. Including re-ruptures as failures, the graft salvage rate was 85% (95% CI 76% to 91%; heterogeneity: tau. 2.  = 0.099, I. 2. = 8.15%, Q = 14.15, df = 13, p = 0.36). Conclusions. Arthroscopic debridement combined with antibiotic treatment can lead to successful eradication of infection and graft salvage, with satisfactory functional outcomes in many cases of septic arthritis following ACL reconstruction. Persistent infection despite repeat arthroscopic debridements requires graft removal with the intention of revision ACL surgery at a later stage. Take home message: Arthroscopic debridement combined with antibiotic therapy is an appropriate initial approach in most cases of septic arthritis following ACL reconstruction, achieving graft salvage rates of about 85%.

Aims. We performed a systematic review of the literature to determine whether earlier surgical repair of acute rotator cuff tear (ARCT) leads to superior post-operative clinical outcomes. Methods. The MEDLINE, Embase, CINAHL, Web of Science, Cochrane Libraries, controlled-trials.com and clinicaltrials.gov databases were searched using the terms: ‘rotator cuff’, or ‘supraspinatus’, or ‘infraspinatus’, or ‘teres minor’, or ‘subscapularis’ AND ‘surgery’ or ‘repair’. This gave a total of 15 833 articles. After deletion of duplicates and the review of abstracts and full texts by two independent assessors, 15 studies reporting time to surgery for ARCT repair were included. Studies were grouped based on time to surgery < 3 months (group A, seven studies), or > 3 months (group B, eight studies). Weighted means were calculated and compared using Student’s t-test. . Results. Group B had a significantly higher pre-operative Constant score (CS) (p < 0.001), range of movement in external rotation (p = 0.003) and abduction (p < 0.001) compared with group A. Both groups showed clinical improvement with surgical repair; group A had a significantly improved Constant score, University of California, Los Angeles (UCLA) shoulder score, abduction and elevation post-operatively (all p < 0.001). Group B had significantly improved Constant score (p < 0.001) and external rotation (p < 0.001) post-operatively. The mean Constant score improved by 33.5 for group A and by 27.5 for group B. Conclusion. These findings should be interpreted with caution due to limitations and bias inherent to case-series. We suggest a trend that earlier time to surgery may be linked to better Constant score, and active range of movement in abduction and elevation. Additional prospective studies are required

Background to the study. The use of Patient Reported Outcome Measures (PROMs) to measure effectiveness of care, and supporting patient management is being advocated increasingly. When evaluating outcome it is important to identify a PROM with good measurement properties. Purpose of the study. To review the measurement properties of the low back and neck versions of the Bournemouth Questionnaire. Methods. Bibliographic databases (e.g. EMBASE, MEDLINE, CINAHL and PsycInfo) were searched for articles evaluating the measurement properties of the Bournemouth Questionnaire. Articles were excluded that did not evaluate measurement properties of this instrument. The methodological quality of the studies selected was evaluated using the COSMIN checklist with the four point rating scale. Studies were rated as “excellent”, “good”, “fair” or “poor” based on completion of the checklist. Results. The initial search produced 6265 hits. A total of 13 studies were included in the final evaluation. Seven studies used the Bournemouth Questionnaire neck version, and six studies involved the back version. Cross-cultural translation was reported in six studies, reliability data were reported in eight studies, and responsiveness in ten studies. Conclusion. The review's findings suggest that the Bournemouth Questionnaire has suitable measurement properties for benchmarking practice in musculoskeletal settings. Conflicts of interest. None. Sources of funding. This study was sponsored by the National Council for Osteopathic Research (. www.ncor.org.uk. )

We performed a systematic review of the optimal management of septic arthritis in children as recommended in the current English literature using MEDLINE, EMBASE, CINAHL, the Cochrane Library and reference lists of retrieved articles without date restrictions up to 31 January 2009. From 2236 citations, 227 relevant full-text articles were screened in detail; 154 papers fulfilled the inclusion criteria, from which conclusions were drawn on the management of infected joints in children. Our review showed that no single investigation, including joint aspiration, is sufficiently reliable to diagnose conclusively joint infection. The roles of aspiration, arthrotomy and arthroscopy in treatment are not clear cut, and the ideal duration of antibiotic therapy is not yet fully defined. These issues are discussed. Further large-scale, multi-centre studies are needed to delineate the optimal management of paediatric septic arthritis

A delay in the diagnosis of paediatric acute and subacute haematogenous osteomyelitis can lead to potentially devastating morbidity. There are no definitive guidelines for diagnosis, and recommendations in the literature are generally based on expert opinions, case series and cohort studies. All articles in the English literature on paediatric osteomyelitis were searched using MEDLINE, CINAHL, EMBASE, Google Scholar, the Cochrane Library and reference lists. A total of 1854 papers were identified, 132 of which were examined in detail. All aspects of osteomyelitis were investigated in order to formulate recommendations. On admission 40% of children are afebrile. The tibia and femur are the most commonly affected long bones. Clinical examination, blood and radiological tests are only reliable for diagnosis in combination. Staphylococcus aureus is the most common organism detected, but isolation of Kingella kingae is increasing. Antibiotic treatment is usually sufficient to eradicate the infection, with a short course intravenously and early conversion to oral treatment. Surgery is indicated only in specific situations. Most studies were retrospective and there is a need for large, multicentre, randomised, controlled trials to define protocols for diagnosis and treatment. Meanwhile, evidence-based algorithms are suggested for accurate and early diagnosis and effective treatment

Objectives. Our objective was to perform a systematic review of the literature and conduct a meta- analysis to investigate the effect of initial varus or valgus displacement of proximal humerus on the outcomes of patients with proximal humerus fractures treated with open reduction and internal fixation. Methods. In accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement standards, we performed a systematic review. Electronic databases MEDLINE, EMBASE, CINAHL and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched to identify randomised and non-randomised studies comparing postoperative outcomes associated with initial varus versus initial valgus displacement of proximal humerus fracture. The Newcastle–Ottawa scale was used to assess the methodological quality and risk of bias of the selected studies. Fixed-effect or random-effects models were applied to calculate pooled outcome data. Results. We identified two retrospective cohort studies and one retrospective analysis of a prospective database, enrolling a total of 243 patients with proximal humerus fractures. Our analysis showed that initial varus displacement was associated with a higher risk of overall complication (RR 2.28, 95% CI 1.12–4.64, P = 0.02), screw penetration (RR 2.30, 95% CI 1.06–5.02, P = 0.04), varus displacement (RR 4.38, 95% CI 2.22–8.65, P < 0.0001), and reoperation (RR 3.01, 95% CI 1.80–5.03, P < 0.0001) compared to valgus displacement. There was no significant difference in avascular necrosis (RR 1.43, 95% CI 0.62–3.27, P = 0.40), infection (RR 1.49, 95% CI 0.46–4.84, P = 0.51), and non-union or malunion (RR 1.37, 95% CI 0.37–5.04, P = 0.64). Conclusions. The best available evidence demonstrates that initial varus displacement of proximal humerus fractures is associated with higher risk of overall complication, screw penetration, varus displacement, and reoperation compared to initial valgus displacement. The best available evidence is not adequately robust to make definitive conclusions. Further high quality studies, that are adequately powered, are required to investigate the outcomes of initial varus and valgus displacement in specific fracture types

Objectives. Our objective was to perform a systematic review of the literature and conduct a meta-analysis to investigate the outcomes of open versus arthroscopic methods of ankle fusion. Methods. In accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement standards, we performed a systematic review. Electronic databases MEDLINE, EMBASE, CINAHL and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched to identify randomised and non-randomised studies comparing outcomes of arthroscopic and open ankle arthrodesis. The Newcastle-Ottawa scale was used to assess the methodological quality and risk of bias of the selected studies. Fixed-effect or random-effects models were applied to calculate pooled outcome data. Results. We identified one prospective cohort study and 5 retrospective cohort studies, enrolling a total of 286 patients with ankle arthritis. Our analysis showed that open ankle fusion was associated with a lower fusion rate (OR 0.26, 95% CI 0.13–0.52, P = 0.0002), longer tourniquet time (MD 16.49, 95% CI 9.46–23.41, P<0.00001), and longer length of stay (MD 1.60,95% CI 1.10–2.10, P<0.00001) compared to arthroscopic ankle fusion; however, there was no significant difference between two groups in terms of infection rate (OR 2.41, 95% CI 0.76–7.64, P = 0.14), overall complication rate (OR: 1.54, 95% CI 0.80–2.96, P = 0.20), and operation time (MD 4.09, 95% CI −2.49–10.66, P = 0.22). The between-study heterogeneity was high for tourniquet time but low or moderate for other outcomes. The direction of the effect sizes remains unchanged throughout sensitivity analyses. Conclusions. The best available evidence demonstrates that arthroscopic ankle fusion may be associated with a higher fusion rate, shorter tourniquet time, and shorter length of stay compared to open ankle fusion. We found no significant difference between two groups in terms of infection rate, overall complication rate, and operation time. The best available evidence is not adequately robust to make definitive conclusions. Long-term results of the comparative efficacy of arthroscopic ankle fusion over open ankle fusion are not currently available. Further high quality randomised controlled trials that are adequately powered are required

Aims

We introduced a self-care pathway for minimally displaced distal radius fractures, which involved the patient being discharged from a Virtual Fracture Clinic (VFC) without a physical review and being provided with written instructions on how to remove their own cast or splint at home, plus advice on exercises and return to function.

We performed a systematic review to compare outcomes of cemented versus uncemented trapezio-metacarpal joint (TMCJ) replacement for treatment of base-of-thumb arthritis. We assessed improvements in pain and function, range of movement (ROM), strength, complications and need for revision surgery. A thorough literature search was performed. A total of 481 studies were identified from the literature search (179 Medline, 253 Embase, 27 CINAHL, 22 Cochrane). Of 43 relevant titles 28 were selected for full-text review after assessment of the abstracts. Duplicate studies were removed. 18 studies met inclusion criteria on full-text review. All studies were of level IV evidence. There were no randomised controlled trials or meta-analyses. The studies were critically appraised using a validated scoring system. Most studies reported good outcomes for pain and strength, and functional outcome was comparable for both groups. ROM was generally improved for both prosthetic types, however statistical calculation was lacking in many studies. Trapezial component loosening was the main problem for both cemented and uncemented prostheses, however radiological loosening did not necessarily correlate with implant failure. This systematic review has found that both cemented and uncemented replacements generally give good outcomes for the treatment of TMCJ arthritis, however young, male, patients with manual occupations and with disease in the dominant hand and patients with poor trapezial bone stock appear to be at higher risk for implant failure due to cup loosening. We recommend the construction of a joint registry to record implantation and revision rates

Introduction. The management of adolescent hallux valgus (AHV) remains controversial, with reservations about both conservative and surgical treatments. Non-operative management has a limited role in preventing progression. Surgical correction of AHV has, amongst other concerns, been associated with a high prevalence of recurrence of deformity after surgery. We conducted a systematic review to assess clinical and radiological outcomes following surgery for AHV. Methods & Materials. A comprehensive literature search was performed in the Cochrane Library, CINAHL, EMBASE, Google Scholar, and Pubmed. The study was performed in accordance with the recommendations of the PRISMA guidelines. Demographic data, radiographic parameters, and results of validated clinical scoring system were analysed. Results. Nine contemporary studies reporting on 201 osteotomies in 140 patients were included. The female to male ratio was 10:1. Mean age at operation was 14.5 years (10.5–22). Mean follow-up was 41.6 months (12–134). The mean post-operative AOFAS score was 85.8 (sd ±7.38). The mean AOFAS patient satisfaction showed that 86% (sd ± 11.27) of patients satisfied or very satisfied with their outcome. On the DuPont BRS, 90% rated their outcome as good or excellent. There was a statistically significant improvement in the IMA (p=0.0003), HVA (p<0.0001), and DMAA (p=0.019). The main complication was persistent pain (12%); others included infection (2%), scar hypersensitivity (4.5%), and non-union, metatarsalgia, and CRPS (each at 0.5%), and no reports of metatarsal head AVN. Conclusion. Based on the most current published evidence, surgery for AHV shows excellent clinical and radiological outcomes, with high patient satisfaction. The rates of recurrence and other complications are lower than the historically reported figures. There is, however, a need for high level, multi-centre collaborative studies with prospective data to establish the long-term outcomes and optimal surgical procedure(s)

Aims

To describe outcome reporting variation and trends in non-pharmacological randomized clinical trials (RCTs) of distal tibia and/or ankle fractures.

Aims

Proximal humeral fractures are the third most common fracture among the elderly. Complications associated with fixation include screw perforation, varus collapse, and avascular necrosis of the humeral head. To address these challenges, various augmentation techniques to increase medial column support have been developed. There are currently no recent studies that definitively establish the superiority of augmented fixation over non-augmented implants in the surgical treatment of proximal humeral fractures. The aim of this systematic review and meta-analysis was to compare the outcomes of patients who underwent locking-plate fixation with cement augmentation or bone-graft augmentation versus those who underwent locking-plate fixation without augmentation for proximal humeral fractures.

Aims

Chronic osteomyelitis (COM) of the lower limb in adults can be surgically managed by either limb reconstruction or amputation. This scoping review aims to map the outcomes used in studies surgically managing COM in order to aid future development of a core outcome set.

Aims

There has been an increasing use of early operative fixation for scaphoid fractures, despite uncertain evidence. We conducted a meta-analysis to evaluate up-to-date evidence from randomized controlled trials (RCTs), comparing the effectiveness of the operative and nonoperative treatment of undisplaced and minimally displaced (≤ 2 mm displacement) scaphoid fractures.

Aims

Spinopelvic characteristics influence the hip’s biomechanical behaviour. However, to date there is little knowledge defining what ‘normal’ spinopelvic characteristics are. This study aims to determine how static spinopelvic characteristics change with age and ethnicity among asymptomatic, healthy individuals.

Electrical stimulators are commonly used to accelerate fracture healing, resolve nonunions or delayed unions, and to promote spinal fusion. The efficacy of electrical stimulator treatment, however, remains uncertain. We conducted a meta-analysis of randomised sham-controlled trials to establish the effectiveness of electrical stimulation for bone healing. We searched MEDLINE, EMBASE, CINAHL and Cochrane Central to identify all randomised sham-controlled trials evaluating electrical stimulators in patients with acute fractures, non-union, delayed union, osteotomy healing or spinal fusion, published up to February 2015. Our outcomes were radiographic nonunion, patient-reported pain and self-reported function. Two reviewers independently assessed eligibility and risk of bias, performed data extraction, and rated overall confidence in the effect estimates according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Fifteen randomised trials met our inclusion criteria. Electrical stimulation reduced the relative risk of radiographic nonunion or persistent nonunion by 35% (95%CI 19% to 47%; 15 trials; 1247 patients; number needed to treat = 7; p < 0.01; moderate certainty). Electrical stimulation also showed a significant reduction in patient-reported pain (Mean Difference (MD) on the 100-millimeter visual analogue scale = −7.67; 95% CI −13.92 to −1.43; 4 trials; 195 patients; p = 0.02; moderate certainty). Limited functional outcome data showed no difference with electrical stimulation (MD −0.88; 95% CI −6.63 to 4.87; 2 trials; 316 patients; p = 0.76; low certainty). Patients treated with electrical stimulation as an adjunct for bone healing have a reduced risk of radiographic nonunion or persistent nonunion and less pain; functional outcome data are limited and requires increased focus in future trials

Joint arthroplasty is a common surgical procedure, with over 185,000 primary hip and knee arthroplasties performed in England, Wales and Northern Ireland in 2014. After total hip or knee arthroplasty, about 1% of patients develop deep prosthetic joint infection (PJI), which usually requires further major operations to clear the infection. Although PJI affects only a small percentage of patients it is one of the most devastating complications associated with this procedure. Research evidence has focussed on clinical effectiveness of revision surgery while there has been less focus on the impact on patients and support needs. Using a systematic review approach, the aim of this study was to assess support needs and evaluate what interventions are routinely offered to support patients undergoing treatment for PJI following hip or knee arthroplasty. We systematically searched MEDLINE, Embase, Web of Science, PsycINFO, Cinahl, Social Science Citation Index, and The Cochrane Library from 1980 to February 15, 2015 for observational (prospective cohort, nested case-control, case-control, and retrospective cohort) studies, qualitative studies, and clinical trials that report on the support needs and interventions for patients being treated for PJI or other major adverse occurrences following joint arthroplasty. Data were extracted by two independent investigators and consensus reached with involvement of a third. Of 4,161 potentially relevant citations, we identified one case-control, one prospective cohort and two qualitative studies for inclusion in the synthesis. Patients report that PJI and treatment had a profoundly negative impact affecting physical, emotional, social and economic aspects of their lives. No study evaluated support interventions for PJI or other major adverse occurrences following hip and knee arthroplasty. The interpretation of study results is limited by variation in study design, outcome measures and the small number of relevant eligible studies. Findings show that patients undergoing treatment for PJI have extensive physical, psychological, social and economic support needs. Our review highlights a lack of evidence about support strategies for patients undergoing treatment for PJI and other adverse occurrences. There is a need to design, implement and evaluate interventions to support these patients

Researchers and clinicians measuring outcomes following total ankle replacement (TAR) are challenged by the wide range of outcome measures used in the literature without consensus as to which are valid, reliable, and responsive in this population. This review identifies region- or joint-specific outcome measures used for evaluating TAR outcomes and synthesises evidence for their measurement properties. A standard search strategy was conducted of electronic databases MEDLINE, EMBASE and CINAHL (to June 2015) to identify foot/ankle measures in use. A best evidence synthesis approach was taken to critically appraise measurement properties [COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN)] of identified measures. The review was restricted to English publications and excluded cross-cultural adaptations. Measurement properties collected from each article were coded for validity, reliability, responsiveness, or interpretability. Clinimetric evidence exists for identified measures tested in non-TAR populations, but were not the focus of this review. The search identified 14 studies to include in the best evidence synthesis with 32 articles providing clinimetric evidence for eight of the measures (one CBO, seven PRO), however only five measures were tested in a TAR population (Foot Function Index, Ankle Osteoarthritis Scale, American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale [AOFAS], Foot and Ankle Outcome Score, Self-Reported Foot and Ankle Score). Five studies provided clinimetric evidence in a TAR population and their methodological quality was assessed: (1) Validity—two good quality studies examining different measures provide moderate evidence supporting construct validity (FFI, AOS, AOFAS self-reported items; SEFAS); (2) Reliability—two good quality studies examining different measures provide moderate evidence supporting internal consistency and test-retest reliability (FFI, AOS, AOFAS self-reported items; FAOS, SEFAS); (3) Responsiveness—three poor quality studies, thus unknown evidence for responsiveness; (4) Interpretability—two studies provide interpretability values (AOS, FFI, AOFAS self-reported items; AOS). This review offers a basis for choosing the most appropriate instrument for evaluating TAR outcomes. Numerous outcome measures were identified with evidence supporting their use in populations with various foot/ankle conditions, but none have strong evidence supporting use in a TAR population. Measures must have adequate clinimetric properties in all patient groups in which they are applied. Evidence supporting or critiquing an instrument should not be based on studies with poor quality methodology, as identified by this review. Further testing in a TAR population would benefit identified measures with emphasis on adequate sample sizes, testing a priori hypotheses, and evaluating their content validity for a TAR population

Background and purpose. To identify methods used to measure free living sedentary behaviour in people with back pain and review the validity and reliability of identified measures. Methods. Databases including CINAHL, EMBASE, MEDLINE, AMED, PsycINFO, SPORTDiscus and the Sedentary Behaviour and Research Network website (. www.sedentarybehaviour.org. ) were searched for relevant published articles up to June 2014. Studies which measured sedentary behaviour in people with back pain were included. Quality of the included studies was assessed using the Newcastle Ottawa Scale. The Consensus-based Standards for the Selection of Measurement Instruments (COSMIN) Checklist was used to assess psychometric properties. Results. Six papers were identified; two of high methodological quality. The most common method of data collection was self-report, using activity diaries or questionnaires. Sedentary behaviour measured by accelerometry ranged from 6.7 to 10.7 hours per day whereas results from self-report measures ranged from 5 to 9.4 hours per day. According to the COSMIN checklist, the psychometric properties of the measurement instruments were rated fair to excellent. Conclusion. People with back pain spend a large proportion of their waking day participating in sedentary behaviour. Therefore valid and reliable sedentary behaviour measurements, such as those identified in this study, are essential for assessing the effectiveness of public health interventions and for future population monitoring.

Background. Osteoarthritis (OA) and chronic low back pain (CLBP > 12 weeks duration) are two of the most common and costly chronic musculoskeletal conditions globally. Healthcare service demands mean that group-based multiple condition interventions are of increasing clinical interest and a priority for research, but no reviews have evaluated the effectiveness of group-based physiotherapy-led self-management interventions (GPSMI) for both conditions concurrently. Rapid review methodologies are an increasingly valid means of expediting knowledge dissemination and are particularly useful for addressing focused research questions. Methods. The electronic databases of MEDLINE, EMBASE, CINAHL, Cochrane Database of Systematic Reviews and Cochrane Register of Controlled Trials were searched from the earliest date possible to August 26. th. 2013. Structured group-based interventions that aimed to promote self-management and that were delivered by health-care professionals (including at least one physiotherapist) involving adults with OA and/or CLBP were eligible for inclusion. The screening and selection of studies, data extraction and risk of bias assessment were conducted independently by two reviewers. Results. 22 studies were found (10 OA, 12 CLBP). The most commonly assessed outcomes were pain, disability, quality of life and physical function. No significant difference was found between the effectiveness of GPSMI and individual physiotherapy or usual general practitioner care for any outcome. Conclusion. GPSMI is as clinically effective as individual physiotherapy, but the best methods of measuring clinical effectiveness warrant further investigation. Further research is also needed to determine the cost-effectiveness of GPSMI and its implications. Conflicts of interest: No conflicts of interest.

Aims

Recurrent dislocation is both a cause and consequence of glenoid bone loss, and the extent of the bony defect is an indicator guiding operative intervention. Literature suggests that loss greater than 25% requires glenoid reconstruction. Measuring bone loss is controversial; studies use different methods to determine this, with no clear evidence of reproducibility. A systematic review was performed to identify existing CT-based methods of quantifying glenoid bone loss and establish their reliability and reproducibility

Background. Shoulder impingement syndrome (SIS) is a common debilitating condition, treated across multiple health disciplines including Orthopaedics, Physiotherapy, and Rheumatology. There is little consistency in diagnostic criteria with ‘Shoulder impingement syndrome’ being used for a broad spectrum of complex pathologies. We assessed patterns in diagnostic procedures for SIS across multiple disciplines. Methods. This is a systematic review of electronic databases MEDLINE, PubMed, The Cochrane Library, Embase, Scopus and CINAHL five years of publications, January 2009 - January 2014. Search terms for SIS included subacromial impingement syndrome, subacromial bursitis. Searches were delimited to articles written in English. The PRISMA guidelines were followed. Two reviewers independently screened all articles, data was then extracted by one reviewer and twenty percent of the extraction was independently assessed by the co-reviewer. Studies included were intervention studies examining individuals diagnosed with SIS and we were interested in the process and method used for the diagnosis. Results. The search strategy yielded 3339 articles of which 1931 were duplicates. A further 1260 were excluded based on relevance obtained from title/abstract. A total of 148 articles were identified investigating SIS across thirty different journals internationally. Fourteen different health disciplines have investigated twenty-five different surgical and conservative treatments. Studies document their diagnostic approach, reporting on duration of symptoms, medical history, physical examination tests and radiological investigations. Duration of symptoms for inclusion ranged from a minimum of 2 weeks to 18 months where the median duration of symptoms is 3 months observed in 46 percent of the studies. Commonly used physical tests were Neer's test, Hawkins-Kennedy test, Jobe and Yocum, and a further eight tests identified. Neer's test or Hawkins-Kennedy tests were individually used in 72 percent of studies. Thirty of the studies used more than one and up to six physical tests per study to determine the presence of impingement. Radiological investigations were reported in twenty-eight studies, sixteen of these required more than one radiological investigation to confirm the diagnosis of SIS. Comparisons between disciplines identify important differences in diagnostic criteria used by different health professionals. Conclusions. This study highlights the variety of diagnostic methods which are currently used between health disciplines and will be a useful comparative tool for clinicians. Diagnostic transparency is pertinent for shoulder impingement syndrome to ensure all disciplines are treating the same pathology and importantly to contribute to our understanding of the common pathology

Introduction. Venous thromboembolism (VTE) is an uncommon complication of foot and ankle surgery but has the potential for significant morbidity and mortality. The incidence, risk factors and prevention of VTE in foot and ankle surgery is not clear. Materials and methods. We conducted a systematic review of the literature using MEDLINE, EMBASE, CINAHL, the Cochrane library and reference lists of retrieved articles without language or date restriction upto 31st July 2010. The Coleman methodology score was used to evaluate the quality of studies. From 985 citations, 38 full text articles fulfilled the inclusion criteria. Conclusions were drawn on the incidence, risk factors and prevention of VTE in foot and ankle surgery. Results. The incidence of symptomatic VTE in foot and ankle surgery in general is low; higher incidence has been reported in tendoachilles surgery. There is some evidence that history of prior VTE, immobilisation, non-weight bearing, obesity, hormone replacement therapy and oral contraceptives predispose to VTE in foot and ankle surgery. The evidence on the efficacy of different thromboprophylaxis agents and the optimum duration of treatment is unclear. Conclusion. The current evidence on VTE prophylaxis in foot and ankle surgery is insufficient to draw any firm conclusions. Long term effects of VTE in foot and ankle surgery need to be investigated further. Further large scale, multicentre studies are needed to delineate the role of VTE prophylaxis in foot and ankle surgery

Background. In the USA more than half the states have legislated scoliosis school screening with the remaining states having either voluntary screening or no recommendations. The four primary care providers for adolescents with idiopathic scoliosis in the USA (AAOS, SRS, POSNA, AAP) do not support any recommendation against scoliosis screening, given the available literature. In Australia a national self detection program is implemented but in the UK school screening has been abolished since the 1980's. Opponents to scoliosis screening have focused on concerns about a low predictive value of screening, the cost effectiveness of referral, the possibility of unnecessary brace treatment and the effect of exposure to radiation when radiographs are obtained. Objectives. The purpose of this review was to evaluate the evidence for and against scoliosis screening. Methods. The following databases were searched: Cochrane Library, ARIF, TRIP, MEDLINE, EMBASE and CINAHL. Reference lists of articles were searched for relevant systematic reviews and research articles. Results. One systematic review (2008). 1. suggests that there is evidence (level 1B) that intensive scoliosis specific exercise methods can reduce the progression of mild scoliosis (<30 degrees Cobb). Further a Cochrane review (2010). 2. suggests that there is low quality evidence for the effectiveness of bracing. Conclusions. Based on the evidence of this review, a 4 tier model for school screening is proposed that includes the distribution of information leaflets, screening by a school nurse, topographical assessment, referral to the primary care doctor and finally if the patient is still screening positive, referral to a scoliosis surgeon. Category: Deformity/screening. Ethics approval: none needed for a review. Interest statement: none

Scoliosis school screening is either mandatory or recommended in 32 states in the USA. The remaining states having either got voluntary screening or no recommendations. The four primary care providers for adolescents with idiopathic scoliosis in the USA do not support any recommendation against scoliosis screening, given the available literature. In Australia a national self detection program is implemented but in the UK school screening has been abolished since the 1980's. Opponents to scoliosis screening have focused on concerns about a low predictive value of screening, the cost effectiveness of referral, the possibility of unnecessary brace treatment and the effect of exposure to radiation when radiographs are obtained. The purpose of this review was to evaluate the evidence for and against scoliosis screening. The following databases were searched: Cochrane Library, ARIF, TRIP, MEDLINE, EMBASE and CINAHL. Reference lists of articles were searched for relevant systematic reviews and research articles. One systematic review (2008). 1. suggests that there is evidence (level 1B) that intensive scoliosis specific exercise methods can reduce the progression of mild scoliosis (<30 degrees Cobb). Further a Cochrane review (2010) suggests that there is low quality evidence for the effectiveness of bracing. Based on the evidence of this review, a 4 tier model for school screening is proposed that addresses the “opponents” concerns. The model includes the distribution of information leaflets, screening by a school nurse, topographical assessment, referral to the primary care doctor and finally if the patient is still screening positive, referral to a scoliosis surgeon. Exercises reduce the progression rate of adolescent idiopathic scoliosis:

Purpose and background. Although low back pain (LBP) with leg pain, is considered by most a poor prognostic indicator, it is at the same time believed to have a favourable natural resolution, and is often treated along similar lines to non-specific LBP, in line with current guidelines. It is unclear whether patients with LBP and leg pain are a distinct subgroup that might benefit from early identification and targeted interventions. We set out to investigate the impact of LBP with leg pain on health outcomes and health resources compared with that of LBP alone, and to explore which factors contribute to the observed disability outcomes. Methods. A systematic literature search of all English language peer reviewed publications was conducted using Medline, EMBASE, and CINAHL for the years 1994 to 2009. Results. Of the 89 papers retrieved, 9 were included in the review. The heterogeneity of data allowed only for narrative analysis of findings. All studies reported worsening baseline health status in terms of poorer self-assessment and increasing use of health care the further the radiation of leg pain. Differences in quality of life measures were higher for physical than for mental health dimensions. Pain and disability outcome at follow up assessment appeared to be less favourable in this group than for individuals with LBP alone. Conclusion. LBP with leg pain is associated with poorer health outcomes and increased use of health resources. These findings argue for early identification of these cases by health care professionals and for pursuing effective treatments rather than simply treating similarly to non-specific LBP

Introduction. Surgeons, commissioners and patients are increasingly seeking more in depth details on outcomes of total ankle replacement (TAR). We set out to perform a detailed and up to date meta-analysis of the outcomes of TAR, with a focus on PROMS. Methods. We searched MEDLINE, Cochrane, EMBASE, CINAHL and the Science Citation Index databases using the terms “total”; “ankle”; “arthroplasty” or “replacement” to April 2012. We included all languages; series with greater than 20 TAR; minimum 2 years follow-up. We excluded papers on revisions; prostheses no longer marketed; and kin studies. We worked with the Cochrane Collaboration to adopt their methodology including the creation of a risk profile assessing all forms of bias. Results. Of 1841 papers identified, 51 remained for analysis, with a pool of 6719 patients. The mean patient age was 59.3(17–95) and mean BMI was 28.8(19.4–44). 53% of patients were male. The most common indication was posttraumatic osteoarthritis. The majority of the studies were level IV and more than half the studies had several forms of bias. Intraoperative complication rate was 9%, with medial malleolar fracture (4.4%) being the most common. The pooled mean pre-op VAS was 7.6 which improved to 1.5 at 4–5 years. The mean pre-op AOFAS was 39.7, improving to 79.9 for up-to 10 years. Range-of-motion increased after TAR from 22.8° preoperatively to 33.6° postoperatively. Radiographic abnormalities were found in 22% of cases with a mean follow up of 53 months, of which 7.9% were re-operated upon. Gait velocity, cadence, stride length and power all improve following TAR. Survival at 8–10 years was 89.4%, with a cumulative failure rate of 1.9%. Conclusion. This is the most comprehensive meta-analysis carried out on TAR to date. TAR provides patients with an increased range of motion and improvement postoperative PROMS maintained up to 10 years

Background: Mind body therapies are being used increasingly to manage chronic musculoskeletal pain. We aimed to systematically review studies to explore the effectiveness of these mind-body therapies (MBTs). Method: The following databases were searched MEDLINE, Psychinfo, AMED and CINAHL. Randomised controlled trials (RCTs), cohort studies, and case series studying adults with chronic musculoskeletal disorders were included. MBTs of interest were biofeedback, hypnosis, guided imagery, meditation, and progressive muscle relaxation. Papers of any language were included. Selection, data extraction and methodological evaluation of the studies were done independently. Narrative and meta-analyses were conducted where appropriate. Results: The search identified 766 articles, 15 were selected for review, three were before and after studies, 12 were either RCTs or clinical controlled trials. The majority of the studies were of a low quality methodologically, with few participants. Fifteen of the studies reported MBTs reduced pain, this was significant for 7 studies post treatment and for five at follow up. MBTs generally had a positive effect on depression, quality of life, acceptance of pain, use of health care and medication. MBTs were as effective as active interventions such as CBT or education and superior to passive control groups. Conclusion: MBTs may have the potential to reduce pain, depression and improve quality of life. There is not enough evidence to conclude that MBTs are more effective than standard medical care or which type of MBT is more effective. Data suggests that a bio-psychological approach may be beneficial in the treatment of chronic musculoskeletal conditions. Conflicts of Interest: None.

Aim: To systematically review the present evidence-base, assessing the clinical and radiological outcomes following trochleoplasty for trochlear dysplasia. Methods: An electronic literature search was performed using the AMED, British Nursing Index, CINAHL, Cochrane, EMBASE, ovid Medline, Physiotherapy Evidence Database, PsycINFO, Pubmed and Zetoc databases from their inception to August 2007. Reference lists of identified papers and a hand search of specialist knee journals was also undertaken. All English language, human subject clinical studies, detailing the clinical and/or radiological outcomes of patellar instability patients following a trochleoplasty were included. Two independent reviewers appraised each paper using the CASP tool. Results: Six papers comprising of 117 trochleoplasty procedures on 99 patients were reviewed. Clinically and radiologically, trochleoplasty was shown to be a safe and effective procedure to correct patellar instability in trochlear dysplasia patients. However, the CASP tool identified that the evidence-base reviewed presented with a number of methodological limitations. These included: limited use of inferential statistics; not applying reliable outcome measurements; poor description of patient recruitment; and evaluating small samples. Conclusion: Although trochleoplasty may be an effective procedure to correct patellar instability in trochlear dysplasia patients, further study is recommended to assess longer-term outcomes using well-designed studies

Introduction. Back pain is one of the most common health problems in the industrialized world. Although using insoles appears to be common clinical practice, there is no hard data to support its effectiveness in prevention of low back pain. As a part of a Cochrane review, we conducted a literature search to determine the effectiveness of shoe insoles in the prevention and treatment of non-specific back pain compared to placebo, no intervention, or other interventions. Materials and methods. We identified relevant clinical trials by searching The Cochrane Back Group Specialized Registry, The Cochrane Central Register, MED-LINE, EMBASE and CINAHL. All retrieved abstracts were blinded and were assessed by two independent investigators who decided on their inclusion. All these were again assessed by two different independent investigators, using the eleven items reflecting internal validity recommended by the Cochrane Back Review Group. A trial was considered to be of high quality if six or more out of eleven criteria were met. Results. Our search found a total of 324 references. 8 papers, meeting the predetermined inclusion criteria, were retrieved of which six were found suitable for final evaluation. The clinical trials described in the papers included more than 2400 patients who used insoles for 3–5 months. Two articles with 199 patients demonstrated improvement in low back pain, while three larger studies found no difference between using insoles or no using insoles. Discussion. There is no evidence for recommending the use of insoles for prevention of back pain. Additional high quality trials must be done to determine if they are effective in the treatment of low-back pain

Purpose: To examine patterns of physical injury associated with intimate partner violence (IPV) among women presenting to emergency room departments. Method: Systematic searches of Medline, EMBASE, and CINAHL electronic databases from their earliest entries up to February 2008. Reference lists from the studies included from the electronic database search were reviewed for published and unpublished studies. We contacted study authors regarding published and unpublished information. After titles and abstracts were initially screened by a single reviewer, two reviewers screened the remaining full-text articles for inclusion into the review. Studies were included if they pertained in whole or in part to women who presented to an emergency department because of IPV and reported the location or type of injuries. Studies without comparison groups of non-IPV women and case series/case reports were excluded. We performed a meta-analysis of the available data using the random effects model. Results: We identified 262 potentially relevant titles and abstracts, of which 7 articles were included in the review. The association between head, neck, or facial injuries and IPV was higher among studies that excluded women with verifiable injuries such as witnessed falls or motor vehicle collisions (pooled odds ratio 24 (95%CI: 15 Ã. -. ¿½ 38)). Thoracic, abdominal, or pelvic injuries were non-specific for IPV (pooled odds ratio 1.07 (95% CI: 0.89 Ã. -. ¿½ 1.29)). Injuries in the upper extremities were suggestive of non-IPV etiology (pooled odds ratio 0.51 (95%CI: 0.41 Ã. -. ¿½ 0.54)), as were lower extremity injuries (pooled odds ratio 0.15 (95%CI: 0.04 Ã. -. ¿½ 0.56)). Conclusion: Among women presenting to emergency room departments, unwitnessed head, neck, or facial injuries are significant markers for intimate partner violence. Conversely extremity injuries are less likely to have been the consequence of IPV

Background: Traditionally, non-displaced scaphoid fractures are considered by most as stable with predictable rates of healing with conservative treatment. There is a current trend in orthopedic practice, however, to treat non- or minimal displaced fractures with early open reduction and internal fixation. This trend is not evidence based. In this systematic review and meta-analysis, we pool data from trials comparing surgical and conservative treatment for acute scaphoid fractures, thus aiming to summarize the best available evidence. Methods: We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, CENTRAL, MEDLINE, EMBASE, CINAHL and reference list of articles, and contacted researchers in the field. We selected eight randomized controlled trials comparing surgical versus conservative interventions for acute scaphoid fractures in adults. Data were pooled using fixed-effects and randomeffects models with standard mean differences (SMD) and risk ratios for continuous and dichotomous variables respectively. Heterogeneity across studies was assessed with Forest plots and calculation of the I2 statistic. Results: Four-hundred seventeen patients were included in eight trials (205 fractures were treated surgically and 212 conservatively). Most trials lacked scientific rigor. Four studies assessed functional outcome with validated physician- and patient-based outcome instruments. With the numbers available (200 patients), we found a significant difference according to our primary outcome measure, standardized patient-based outcome in favor of surgical treatment (p< 0.0001). With regard to our secondary parameters, we found heterogeneous results that favored surgical treatment for grip strength, time to union and time off work. In contrast we found no significant differences between surgical and conservative treatment for pain, range of motion, rate of nonunion, malunion, and infection, rate of complications, and total treatment costs. Conclusions: Patient-rated functional outcome and satisfaction as well as time to return to function favored surgical treatment for acute scaphoid fractures. However, there is no evidence from prospective randomized controlled trials on physician-rated functional outcome, radiographic outcome, complication rates and treatment costs to favor surgical or conservative treatment for acute scaphoid fractures

Purpose: A significant proportion of spine fusion operations may result in a non-union. Electromagnetic stimulation is a non-invasive method used to promote spine fusion although the efficacy of its use in this regard remains uncertain. The purpose of this systematic review and meta-analysis is to evaluate the effect of electromagnetic stimulation on spine fusion. Method: Five electronic databases (MEDLINE, Embase, CINAHL, PubMed and the Cochrane Central Register of Controlled Trials) were searched from database inception to July 2009 for randomized controlled trials of electrical stimulation and spinal fusion. In addition, we performed a hand search of four relevant journals from January 2000 to July 2009, the on-line proceedings of the North American Spine Society Annual Meeting from 2002 to 2008 and bibliographies of eligible trials. Trials randomizing adult patients undergoing any type of spine fusion to active treatment with direct current, capacitance coupled or pulsed electromagnetic field stimulation or placebo and reporting on fusion rates were included. Two independent reviewers extracted data regarding clinical outcomes, stimulation device, treatment regimen and methodologic quality. Results: Of 1650 studies identified seven met the inclusion criteria. Electromagnetic stimulation in lumbar spine fusion was evaluated in five studies and two addressed cervical spine fusions. The use of electromagnetic stimulation in lumbar spine fusion resulted in a significant decrease in the risk of non-union (relative risk 0.60, 95% confidence interval 0.38 to 0.93, p = 0.02, I2 = 57%). The observed reduction in risk of nonunion with electromagnetic stimulation was not affected by smoking or the number of levels fused. Due to limited and conflicting trials, similar effects were not observed in the two studies evaluating cervical spine fusion rates (relative risk 0.85, 95% confidence interval 0.29 to 2.53, p = 0.77, I2 = 56%). Conclusion: Pooled analysis shows a 40% reduction in the risk of non-union of lumbar spine fusions with the use of electromagnetic stimulation although a similar effect was not observed for fusions of the cervical spine. However, due to study heterogeneity the current indications for the use of electrical stimulation in spine fusion remain somewhat unclear

Background: Low back pain is a common symptom in the general population. There is considerable evidence for the effectiveness of exercise for chronic low back pain but long-term adherence rates can be poor. It may be important to gain a greater understanding of patients’ beliefs about exercise for low back pain and their adherence to it. Objectives: To systematically review studies exploring low back pain patients’ beliefs about exercise as a treatment for their pain. Method: We searched Medline, Web of Science, National Research Register, PEDro, PsycINFO, AMED, CINAHL and EMBASE. Retrieved titles and abstracts were combined and screened for inclusion in the review. We quality appraised the included papers and did a thematic analysis of the data extracted from them. Results: Three studies were eligible for inclusion in the review. The main themes identified were barriers and motivators to exercise. Time was the main barrier patients perceived. Fear of pain acted both as a barrier and a motivator to exercise. Health professionals motivated patients to exercise when the patient had regular contact and felt they understood their situation. Exercise had both physical and mental benefits, with responders feeling enabled to self manage their pain. Conclusions: The impact of the health professional on beliefs about exercise and adherence is already acknowledged in the recommendations for supervised exercises. There is a lack of exploratory research in the area of exercise beliefs, especially in primary care. Further research is needed to understand how people with low back pain view physical activity more generally especially prior to receiving exercise as a treatment

Purpose: ‘Red flags’ are patient responses and findings on history taking and physical examination that are associated with an increased risk of serious spinal disorders. The purpose of this paper is to identify red flags reported in the low back pain literature, establish consensus on whether (or not) they are considered red flags, and review the evidence for these signs and symptoms. Methods: The following databases were searched using key words ‘red flag’ and ‘low back pain’:. MEDLINE (1951→). EMBASE (1974→). CINAHL (1982→). PsycINFO (1806→). AMED (1985→). PEDro. In addition, national guidelines and key texts were hand-searched. Each red flag identified in the literature was classified using The Guidelines Development Group’s format (where 100% coverage = ‘unanimity’; 75–99% = ‘consensus’; 51–74% = ‘majority view’; and 0–50% = ‘no consensus’), and the findings summarized. Results: The electronic searches revealed 54 papers, with the resultant ‘red flags’ ranging from ‘no consensus’ to ‘unanimity’. Evidence for these signs and symptoms is variable. Case reports and series justify labelling some features ‘red flags’, whilst others owe their label to clinical experience and expert opinion. Conclusion: Case reports and series should be reported/ published to help identify those signs and symptoms suggestive of serious spinal disorders and those more likely to be ‘red herrings’. Despite their importance, there is inconsistency within the literature in identifying true red flags and, an ability to identify these signs and symptoms is essential for all who practise spinal assessments

Purpose: Traditionally, the accepted treatments for adolescent idiopathic scoliosis (AIS) have included open anterior thoracotomy with instrumentation and posterior spinal fusion and instrumentation. Thoracoscopic instrumentation is a newer technique, whose role remains controversial. This systematic review of the literature aims to better understand thoracoscopic instrumentation as a treatment for AIS and to discuss it in the context of the alternative techniques currently used. Method: The most commonly used medical databases (PUBMED, Medline, EMBASE, Cinahl, and the Cochrane library) were searched up to April 2008 using the search terms “VATS”, “thoracoscopic scoliosis” and “thoracoscopic scoliosis instrumentation”. Two reviewers independently performed the literature evaluation. There were no language restrictions. Because the number of randomized controlled trials was anticipared to be small, we included relevant non-randomized trials, observational studies, and uncontrolled studies. Results: Eleven studies met the strict inclusion criteria for the systematic review, of which the majority were level III and IV evidence. Four hundred and forty-five cases have been reported, 80% of them female, with the vast majority having a diagnosis of AIS. Similar surgical techniques were used and had a mean operative time of 355 minutes, mean blood loss of 444 ml, and mean hospital stay of 5.1 days. Mean pre-operative curve magnitude was 47.9o; post-operative curve magnitude was 16.3o, with a correction of 62%. Number of levels instrumented was 6.3, pulmonary function testes returned to pre-operative values by 2-years post-operative, and complication rate was 21.6%, including a pulmonary complication rate of 9.2%. SRS questionnaires revealed that patients were satisfied. Conclusion: The major drawbacks of the thoraco-scopic approach are the operative time and incidence of early pulmonary complications. Advantages include: minimally invasive, less blood loss, short hospital stay, excellent curve correction, few levels fused, good patient satisfaction, and no long term effect on pulmonary function. With appropriate surgeon training, careful patient selection, and precise surgical technique, this technique can offer an acceptable alternative to the more traditional procedures

Hip resurfacing procedures have gained increasing popularity for younger, higher demand patients with degenerative hip pathologies. However, with concerns regarding revision rates and possible adverse metal hypersensitivity reactions with metal-on-metal articulations, some authors have questioned the hypothesised superiority of hip resurfacing over total hip arthroplasty. The purpose of this meta-analysis was to compare the clinical and radiological outcomes and complication rates of these two procedures. A systematic review was undertaken of all published and unpublished research up to January 2010. The primary search was of the databases Medline, CINAHL, AMED and EMBASE, searched via Ovid using MeSH terms and Boolian operators ‘hip’ AND ‘replacement’ OR ‘arthroplasty’ AND ‘resurfacing’. A secondary search of unpublished literature was conducted using the databases SIGLE, the National Technical Information Service, the National Research Register (UK), the British Library's Integrated Catalogue and Current Controlled Trials databases using the same search terms as the primary search. All included studies were critically appraised with the CASP appraisal tool. In total, 46 studies were identified from 1124 citations. These included 3799 hip resurfacings and 3282 total hip arthroplasties. On meta-analysis, functional outcomes for subjects following hip resurfacing were better than or the same as subjects with a total hip arthroplasty, with significantly higher WOMAC score (Mean Difference (MD)=−2.41; 95% Confidence Interval (CI): −3.88, −0.94; p=0.001), and significantly better Harris Hip Score (range of motion component) (MD=−0.05; 95% CI: (−0.07, −0.03; p<0.0001) and overall Harris Hip Score (MD=2.51; 95% CI: 1.24, 3.77; p=0.0001) in the hip resurfacing compared to total hip arthroplasty cohorts. However, there were significantly greater incidences of heterotopic ossification (Risk Ratio (RR)=1.62; 95% CI: 1.23, 2.14; p=0.006), aseptic loosening (RR=3.07; 95% CI:1.11, 8.50;p=0.03) and revision surgery (RR=1.72; 95% CI: 1.20, 2.45; p=0.003) with hip resurfacing compared to total hip arthroplasty. The evidence-base presented with a number of methodological inadequacies such as the limited use of power calculations and poor or absent blinding of both patients and assessors, potentially giving rise to assessor bias. In respect to these factors, the current evidence-base, whilst substantial in its size, may be questioned in respect to its quality in determining superiority of hip resurfacing over total hip arthroplasty

Aim: A meta-analysis of randomised controlled trials was performed to investigate the effectiveness of surgical fusion for chronic low back pain compared to non-surgical intervention. Methods: Several electronic databases (MEDLINE, EMBASE, CINAHL and Science Citation Index) were searched from 1966 to October 2005. Two authors independently extracted data. The meta-analysis comparison was based on mean difference in Oswestry disability index (ODI) change from baseline to follow up of patients undergoing surgical versus non-surgical treatment. Results: Four studies of 58 articles identified in the search were eligible with a total of 740 patients. One of the studies recruited patients with adult isthmic spondylolisthesis, whereas the other studies recruited patients with a history of chronic low back pain of at least 1 year duration. Surgical treatment involved pos-terolateral fusion with or without instrumentation and flexible stabilisation. Non-surgical treatment involved exercise programs with or without cognitive therapy. The follow-up period ranged from 1 to 2 years. The mean overall difference in ODI between the surgical and non-surgical groups was statistically in favour of surgery (mean difference of ODI: 3.90; 95% confidence interval: 0.17–7.62; p=0.04; I. 2. =21.4%). Surgical treatment was associated with a 13% pooled rate of early complications (95% confidence interval: 6–20%). Conclusion: Surgical fusion for chronic low back pain favoured an improvement in the ODI compared to non-surgical intervention; this difference in ODI is of minimal clinical importance. Furthermore, surgery is associated with a significant risk of complications. Therefore, the cumulative evidence at present does not support routine surgical fusion for the treatment of chronic low back pain

Aims

Hip fracture is a common condition of the older, frailer person. This population is also at risk from SARS-CoV-2 infection. It is important to understand the impact of coexistent hip fracture and SARS-CoV-2 for informed decision-making at patient and service levels.

Aims: Ulnar nerve compression at the elbow known as cubital tunnel syndrome is the second most common compression neuropathy of the upper limb. There is currently no consensus on the optimal operative treatment approach. The objective of this meta-analysis of randomized controlled trials was to evaluate the efficacy of simple decompression versus anterior transposition of the nerve in the treatment of cubital tunnel syndrome. Methods: Multiple databases (Medline, Embase, Cochrane Library, Cinahl and several meeting archives) were searched for randomized controlled trials (RCTs) reporting on the outcome of operative treatment of cubital tunnel syndrome in patients with no trauma or previous surgeries. Two reviewers abstracted baseline characteristics, clinical scores and motor nerve conduction velocities independently. Data were pooled across studies, standard mean differences in effect sizes (SMD) weighted by study sample size were calculated and heterogeneity across studies was assessed. Results: We identified four RCTs comparing simple decompression to anterior ulnar nerve transposition (two submuscular and two subcutaneous). Three studies used a clinical scoring system as the primary clinical outcome (n=261). There were no significant differences between simple decompression and anterior transposition. (SMD= − 0.04, 95%CI: −0.36 to 0.28, p=0.81). We did not find significant heterogeneity across studies (I2=34.2%; p=0.22). Two studies presented postoperative motor nerve conduction velocities (n=100) with no significant differences (SMD=0.24 in favor of simple decompression, 95%CI: −0.22 to 0.57, p=0.23; I2=0%; p=0.9). Conclusions: The results of this meta-analysis suggests that there is no difference in motor nerve conduction velocities and clinical outcome scores between simple decompression and ulnar nerve transposition for the treatment of moderate to severe ulnar nerve compression at the elbow in patients with no prior trauma or previous surgeries to the affected elbow. Confidence intervals around the points of estimate are narrow probably excluding clinically meaningful differences. Since ulnar nerve transposition is the more invasive of the two procedures, this data supports the use of simple decompression of the ulnar nerve unless a plausible indication for ulnar nerve transposition exists

Objectives: To compare the results of various surgical approaches to the knee in primary arthroplasty surgery. Design: Systematic review with meta-analysis. Data Sources: Cochrane Bone, Joint, and Muscle Trauma group trials register (2007), Cochrane central register of controlled trials (Cochrane Library issue 2, 2007), Medline (1950 to February 2007), Embase (1974 to February 2007), CINAHL (1982 to February 2007), Pubmed, SCOPUS and ZETOC. If data was insufficient trialists were contacted via telephone, email or letter. Review methods: Randomised and quasi-randomised controlled trials comparing surgical approaches to the knee in patients undergoing primary arthroplasty surgery. Results: Twenty-three randomised, controlled trials (1282 patients, 1490 TKAs) were included. Midvastus vs Medial Parapatellar approach: Quadriceps function in the early post operative period was better preserved in the MV group. Post operative pain, blood loss and the need for LRR tended to be lower in the MV group. There was no difference in ROM, hospital stay, knee scores, complications or radiological alignment. Subvastus vs Medial Parapatellar approach: Quadriceps function was better preserved in the SV group up to 3 months post operatively. ROM was generally greater up to the 4 week time point. Post operative pain and blood loss was lower in the SV group. There was no difference in operative/tourniquet time, hospital stay, rate of LRR, or complications. Modified “Quadriceps sparing” Medial Parapatellar vs Mini-Subvastus (MSV) approach: A tendency for earlier restoration of SLR and better early ROM was noted in the MSV group. Midvastus vs Subvastus approach: The SV group suffered with significantly more pain at six months post operatively. Conclusions: Approaches preserving the quadriceps tendon improve the early extensor mechanism function and tend to decrease the need for LRR. Combined with a decrease blood loss and postoperative pain, these approaches improve early rehabilitation and allow for a more rapid recovery of knee function. However, these early improvements fail to provide any long term benefit, do not improve knee scores, or decrease the length of hospital stay

Purpose and Background: Despite widespread clinical belief, a previous systematic review found insufficient evidence to substantiate fear avoidance beliefs (FAB) as a risk factor for long-term problems in low back pain. This updated review explores whether there is stronger evidence supporting the role of fear avoidance in early stages of low back pain as a predictor of outcome. In addition, this evidence was examined in reference to current models and knowledge about fear avoidance. Methods and Results: A systematic literature search for all prospective inception cohorts of low back pain that included psychological factors at baseline between 2000 and 2003 was made. We searched MEDLINE, psychINFO, AMED, CINAHL, Social Science Citation Index, Science Citation Index databases. Included studies had early recruitment of up to three weeks since onset of back pain and an absence of back pain in the previous three months. These studies were coded according to criteria adapted from Pincus et al (2002) blindly by two researchers. A sample of these was coded by a third blinded reviewer. An independent statistician performed statistical conversion of reported results to effect sizes. Out of the six included studies, four included valid and reliable measures of fear avoidance. There was only weak evidence implicating fear avoidance as a predictor of disadvantageous outcome. Conclusions: There is insufficient evidence to support or refute the basic concept of fear avoidance as a risk factor for poor outcomes in low back pain. Experimental studies indicate that those with high FAB benefit from targeted intervention. To explain this we propose a model of FAB containing two distinct groups

Supracondylar humeral fractures are the most common elbow injury in children, usually sustained from a fall on the outstretched hand. Iatrogenic ulnarnerve injury is not uncommon following cross K wiring. NNH is the number of cases needed to treat in order to have one adverse outcome. A systemic review was undertaken to calculate relative risks, risk difference and number needed to harm following management of supracon-dylar fractures with cross or lateral K wires. It was found that there was one iatrogenic ulnar nerve injury for every twenty-seven cases that were managed with crossed K wires. The aim of this study was to calculate the number of cross K wiring of supracondylar fractures of the humerus that would need to be performed for one iatrogenic ulnar nerve injury to occur. Iatrogenic ulnarnerve injury is not uncommon following cross K wiring of supracondylar fractures of the humerus. To date there are no clinical trials showing the benefit of cross K wiring over lateral K wiring in the management of supracondylar fractures of the humerus in children. If it can be confirmed that lateral K wiring is as effective as crossed K wiring, iatrogenic ulnar nerve injury can be avoided. A systematic review of iatrogenic ulnar nerve injuries following management of supracondylar fractures was conducted. The databases MEDLINE 1966 – present, EMBASE 1980 – present, CINAHL 1982 – present, CDSR, and DARE were searched along with a meticulous search of the Journal of Paediatric Orthopaedics from 1998 to 2004. Of the two hundred and forty-eight papers identified, only thirty-six met the inclusion criteria. The papers where both lateral crossed K wires were used as treatment were identified for calculating relative rates, risk difference and number needed to harm. NNH was 7.69. When a sensitivity analysis removing two studies that had five subjects or fewer and a 100% ulnar nerve injury rate was peformed, the NNH was 27.7. In other words, there was one iatrogenic ulnar nerve injury for every twenty-seven cases that were managed with crossed K wires

Background: Chronic low back pain is the most common complaint of the working age population. Controversy exists regarding the benefit of surgical fusion of the spine for the treatment of chronic low back pain. We performed a meta-analysis of randomised controlled trials to investigate the effectiveness of surgical fusion for chronic low back pain compared to non-surgical intervention. Methods: Several electronic databases (MEDLINE, EMBASE, CINAHL, Science Citation Index and Cochrane registry of clinical trials) were searched from 1966 to October 2005. Two authors independently extracted data on study characteristics and methodological quality and the number of patients with early complications from surgery. The random-effect meta-analysis comparison was based on the mean difference in Oswestry Disability Index (ODI) change from baseline to follow-up of patients undergoing surgical versus non-surgical treatment. Between-study heterogeneity was analyzed by means of I2. Results: Four studies of 58 articles identified in the search were eligible with a total of 740 patients. One of the studies recruited patients with adult isthmic spondy-lolisthesis, whereas the other studies recruited patients with a history of chronic low back pain of at least 1 year duration. Surgical treatment involved posterolateral fusion with or without instrumentation or flexible stabilisation. Non-surgical treatment involved exercise programs with or without cognitive therapy. The follow-up period ranged from 1 to 2 years. The pooled mean difference in ODI between the surgical and non-surgical groups was statistically in favour of surgery (mean difference of ODI: 3.90; 95% confidence interval: 0.17–7.62; p=0.04; I2=21.4%). Surgical treatment was associated with a 13% pooled rate of early complication (95% confidence interval: 6–20%, I2=66.9%). Conclusion: Surgical fusion for chronic low back pain favoured an improvement in the ODI compared to non-surgical intervention. This difference in ODI is of minimal clinical importance. Furthermore, surgery was associated with a significant risk of complications. Therefore, the cumulative evidence at present does not support routine surgical fusion for the treatment of chronic low back pain

Objectives: To compare the results of various surgical approaches to the knee in primary total knee arthroplasty (TKA) surgery. Design: Systematic review with meta-analysis. Data Sources: Cochrane Bone, Joint, and Muscle Trauma group trials register (2007), Cochrane central register of controlled trials (Cochrane Library issue 2, 2007), Medline (1950–2007), Embase (1974–2007), CINAHL (1982–2007), Pubmed, SCOPUS and ZETOC. Review Methods: Randomised and quasi-randomised controlled trials comparing surgical approaches in patients undergoing primary TKA. Relative risks and 95% CIs were calculated for dichotomous outcomes, and weighted mean differences and 95% CIs calculated for continuous outcomes. Individually randomised trials were pooled whenever possible with the use of the fixed-effects model of Mantel-Haenszel. Results: 53 articles were identified using our search strategy; of these, 32 were excluded from the systematic review. 21 trials involving 1082 patients (1170 TKAs) were included. Midvastus (MV) vs Medial Parapatellar (MPP) approach:. Quadriceps function in the early post operative period was better preserved in the MV group. Post operative pain, blood loss and the need for LRR tended to be lower in the MV group. Subvastus (SV) vs Medial Parapatellar approach:. Quadriceps function was better preserved in the SV group up to 3 months post operatively. ROM was generally greater up until the 4 week time point. Post operative pain and blood loss was lower in the SV group. Midvastus vs Subvastus approach:. The SV group suffered with significantly more pain at six months post operatively. Quadriceps-sparing versus Medial Parapatellar Approach:. Significantly longer operative times and more complications were noted in the QS group. Modified ‘Quadriceps sparing’ Medial Parapatellar vs Mini-Subvastus (MSV) approach:. A tendency for earlier restoration of SLR and better early ROM was noted in the MSV group. Conclusions: Approaches preserving the quadriceps tendon improve the early extensor mechanism function and tend to decrease the need for LRR. Combined with a decrease in blood loss and postoperative pain, these approaches improve early rehabilitation and allow for a more rapid recovery of knee function. However, these early improvements fail to provide any long term benefit, do not improve knee scores, or decrease the length of hospital stay. MIS tends to result in an improved early quadriceps function and decreased blood loss. However, these approaches are technically more demanding, result in longer operative times and provide no long-term benefit. There is concern that they result in a greater number of major complications and risk implant mal-alignment. Eversion of the patella seems to correlate with poor quadriceps function

Introduction and Aims: Periprosthetic bone loss is responsible for the majority of cases of implant failure after total joint arthroplasty. Bisphosphonates are effective in reducing bone loss in many conditions associated with accelerated bone turnover. Our aim was to determine the effect of bisphosphonates on periprosthetic bone mineral density (BMD, g/cm2) after total joint arthroplasty. Method: We conducted computerised searches for randomised controlled trials, evaluating the effects of bisphosphonates on periprosthetic bone mineral density in patients undergoing primary total joint arthroplasty. We searched MEDLINE, EMBASE, CINAHL, the Cochrane Central Register of Controlled Trials, the Cochrane Database of Systematic Reviews and the United Kingdom National Research Register Web-site to November 2003. Computerised searches of the archives of AAOS Annual Meetings 1989–2003 were also conducted. Additional strategies to identify articles included a hand search of the bibliographies of relevant articles and direct contact with the authors. Results: Of 386 citations initially identified, nine citations met our eligibility criteria. The total number of randomised controlled trials was six (five published and one abstract). Four trials evaluated total hip arthroplasty and two examined total knee arthroplasty. Five trials used alendronate and one used pamidronate. Quality scores ranged from 65 to 75. The pooled sample size was 290 patients. Less periprosthetic bone loss occurred in the intervention group compared to the control group at the following follow-up intervals: three months (n=128, Weighted Mean Difference (WMD): 3.3%, 95% Confidence Interval (CI): 1.9–4.7, p< 0.01); six months (n=224, WMD: 4.5%, CI: 1.6–7.4, p< 0.001); and 12 months (n=173, WMD: 4.2%, CI: 1.5–6.9, p=0.03). Tests of heterogeneity revealed greater maintenance of BMD in cemented arthroplasty than in uncemented arthroplasty (WMD: 7.5%, CI: 4.3–10.7 versus WMD: 2.1%, CI: 0.61–3.6, respectively, p< 0.001) at 12 months follow-up. Conclusion: Bisphosphonates have a beneficial effect on maintaining periprosthetic bone stock compared to control after total joint arthroplasty. The effect seems greater in cemented arthroplasty and total knee arthroplasty. Whether this increase in BMD results in improved fixation and longevity of prosthetic components remains unanswered. Larger trials evaluating the effect of bisphosphonates on rates of implant loosening and functional outcomes are needed

Background: Intracapsular hip fractures in young adults under 50 years of age have a significant risk of fracture healing complications which has led some authors to advocate urgent fracture reduction and/or open reduction. As these fractures are infrequent, limited information is available from published studies to advocate a particular method of treatment to reduce the risk of complications. The purpose of this study is to analyze outcomes following such fractures with particular reference to the influence of the degree of fracture displacement, timing of surgery, method of reduction (open/closed) on the incidence of non-union and avascular necrosis. Methods: Specific search terms were used to retrieve relevant studies from MEDLINE, EMBASE, and CINAHL extending from 1966 to May 2003. Guidelines for reporting of meta-analysis, adapted from QUOROM statement were followed. Results: Eighteen studies with 564 fractures were identified for analysis. The overall incidence of non-union was 50/564 (8.9%) and avascular necrosis (AVN) was 130/564 (23.0%). There was a higher incidence of non-union and AVN following displaced than undisplaced fractures. Non-union occurred more frequently after open reduction than closed reduction (10/89 [11.2%] versus 13/275 [4.7%], P=0.04, RR=0.42, 95% CI: 0.19 to 0.93). There was an increased incidence of AVN after closed than open reduction (P= 0.0005, RR = 2.77, 95% CI: 1.45 to 5.29) but this became not statistically significant when one study with a markedly higher reported incidence of AVN was excluded (P = 0.07, RR= 1.85, 95% CI: 0.93 to 3.68). The difference in the incidence of non-union and AVN following early (< 12 hours) or late (> 12 hours) surgery was not significant for either non-union or AVN (13/110 [11.8%] versus 3/60 [5.0%], p=0.18, RR2.36, CI 0.70 to 7.97 for non-union, 15/110 [13.6%] versus 9/60 [15.0%], p=0.82, RR=0.91, CI 0.42 to 1.95 for AVN). Conclusion: Early (< 12 hours) or open reduction of these fractures may not reduce the risk of non-union or avascular necrosis. There is a suggestion of a higher incidence of non-union following open reduction than closed reduction. Randomized studies or prospective observational studies with a minimum follow-up of two years are required to report on a larger number of patients in this age group before definite conclusions on treatment can be made

Aims

A systematic literature review focusing on how long before surgery concurrent viral or bacterial infections (respiratory and urinary infections) should be treated in hip fracture patients, and if there is evidence for delaying this surgery.

Aims: The re-dislocation rates in adults (< 30 years) in the initial 12 months after FAT (first,anterior,traumatic) shoulder dislocations treated non-operatively vary from 25% to 95%. Some surgeons advocate early arthroscopic surgery following such dislocations as this appears to reduce recurrent instability. The purpose of this study was to establish if arthroscopic surgery reduces the incidence of recurrent instability after such dislocations when compared to non-operative treatment. Material and Methods: Specific search terms were used to retrieve relevant studies from MEDLINE, EMBASE, and CINAHL extending from 1966 to October 2003. Guidelines for reporting of meta-analysis, adapted from QUOROM statement were followed. Adults under 30 years of age, with clinical and radiological confirmation of anterior dislocation following trauma with a minimum follow-up of 12 months were included. Patients with previous shoulder problems, generalised joint laxity, neurological injury, impingement and a history of substance abuse were excluded. Results: 13 studies involving 433 shoulders were reviewed. Group A included 84 shoulders treated by arthroscopic lavage without stabilisation. There were no subluxations. The re-dislocation rate was 14.3% (12/84). Group B had 179 shoulders treated by arthroscopic stabilisation. The incidence of subluxation was 5.02% (9/179) and dislocation was 6.14% (11/179). Recurrent instability (subluxation /dislocation) following arthroscopic lavage (12/84 – 14.3%) was significantly higher than after arthroscopic stabilisation (20/179 – 11.2%). [p= 0.04, Relative risk = 2.32, 95% CI: 1.07 to 5.05]. Group C involved 170 shoulders treated non-operatively. The incidence of subluxation was 8% (12/150) and dislocation was 62% (93/150). The overall incidence of recurrent instability was 70% (119/170). Recurrent instability following arthroscopic intervention (32/263 – 12.2%) was significantly lower than following non-operative treatment (119/170 – 70%) [p< 0.0001, Relative risk = 0.17, 95% CI: 0.12 to 0.24]. Conclusion: Early arthroscopic surgery reduces recurrent instability during the initial 12 months after FAT shoulder dislocation in young adults (< 30 years) when compared to non-operative treatment. Arthroscopic treatment should be offered to young, athletic patients especially those involved in contact sports or defence personnel, who are at a high risk of recurrent instability after initial shoulder dislocation. Further randomised control trials reporting on a larger number of patients with a minimum follow-up of 5 years are required before one can draw firm conclusions on the ability of arthroscopic intervention to influence the natural history of FAT shoulder dislocation
