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.

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

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. 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.

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
