Aim

Although non-unions being one of the most common complication after long-bone fracture fixation, the definition of this entity remains controversial and varies widely among authors. A clear definition is crucial, not only for the evaluation of published research data but also for the establishment of uniform treatment concepts. The aim of this systematic review was to identify the definitions and different criteria used in the scientific literature to describe non-unions after long bone fractures.

Method

A comprehensive literature search was performed in PubMed, Cochrane Library, Web of Science, and Embase. according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Prospective therapeutic and diagnostic clinical studies in which adult long-bone fracture non-unions were investigated as main subject were included in this analysis.

Shoulder impingement is one of the most common non-traumatic upper limb causes of disability in adults. Often resulting in pain and disability, management remains highly debated. This meta-analysis of randomized trials aims to evaluate the efficacy of surgical intervention in the setting of shoulder impingement in comparison to non-operative or sham treatments.

Two reviewers independently screened MEDLINE, EMBASE, PUBMED and Cochrane databases for randomized control trials published from 1946 through to May 19th, 2018. A risk of bias assessment was conducted for all included studies and outcomes were pooled using a random effects model. The primary outcome was improvement in pain up to two years. Secondary outcomes included functional outcome scores reported at the short term (/=2 years). Heterogeneity was assessed using the I2statistic. Functional outcome scores were presented along with minimal clinically important differences to provide clinical context to findings.

Twelve RCT's (n=1062 patients) were included in this review. Eligible patients were a mean age of 48 (SD +/− 4) years with 45% being male gender. The pooled treatment effect of surgical intervention for shoulder impingement did not demonstrate any benefit to surgery with respect to pain relief (mean difference [MD] −0.07, 95% CI −0.40 to 0.26) or short-term functional outcomes (standardized mean difference [SMD] −0.09, 95% confidence interval [CI] −0.27 to 0.08). Surgical intervention did result in a small statistically significant but clinically unimportant improvement in long term functional outcomes (SMD 0.23, 95% CI 0.06 to 0.41).

Evidence suggests surgical intervention has little, if any, benefit for impingement pathology in the middle-aged patient.

Purpose

Displaced midshaft clavicular fractures are a common injury with a high occurrence rate in young, active individuals. Non-operative care has traditionally been the standard of care for such fractures, but more recent studies have suggested benefits following primary operative fixation. The purpose of this study was to review the literature on displaced midshaft clavicle fractures, identify randomized controlled trials of operative versus non-operative treatment, and pool the functional outcome and complication rates (including nonunion and symptomatic malunion), to arrive at summary estimates of these outcomes.

Method

A systematic review of the literature was performed to identify studies of randomized controlled trials comparing operative versus non-operative care for displaced midshaft clavicle fractures. Meeting abstracts were also searched and included in this study.

Objective. Carpal tunnel release surgery is a commonly performed procedure for alleviating symptoms of median nerve compression and restoring hand function. With pressure on theatre time these procedures are now commonly performed in a step-down out-patient facility under local anaesthetic. The choice of suture for skin closure in this procedure can impact the quality of wound healing, patient outcomes and the follow-up required however the question of the best type of suture remains unanswered. The purpose of this study was to compare the outcomes of absorbable and non-absorbable sutures using a randomised control trial design. Methods. Eighty patients diagnosed with bilateral carpal tunnel syndrome were enrolled and underwent outpatient carpal tunnel release surgery under local anaesthetic in a staged fashion. Random number generation was used to assign each hand to receive interrupted nylon or Vicryl Rapide sutures. Pre-operative data collection included patient demographics, ASA, inflammatory conditions, smoking status as well as a Boston Carpal Tunnel Questionnaire (BCTQ) for each hand. Patients were followed up at 2 and 6 weeks after each operation and the BCTQ was repeated along with the Patient and Observer Scar Assessment Scale and the VAS score for wound discomfort. This study has approval from the DHB ethics committee, Local Iwi, HDC and ANZ Clinical Trials:ACTRN12623000100695. Results. Statistical analysis assessed patient preference and the scores between the groups. Multi-variate analysis was performed to assess the factors that may be contributing to patient choice. Conclusion. Insights into patient preference and clinical outcomes associated with absorbable sutures and non-absorbable sutures in the setting of out-patient surgery are discussed

To date, the literature has not yet revealed superiority of Minimally Invasive (MI) approaches over conventional techniques. We performed a systematic review to determine whether minimally invasive approaches are superior to conventional approaches in total hip arthroplasty for (1) clinical and (2) functional outcomes. We performed a meta-analysis of level 1 evidence to determine whether (3) minimally invasive approaches are superior to conventional approaches for clinical outcomes. All studies comparing MI approaches to conventional approaches were eligible for analysis. The PRISMA guidelines were adhered to throughout this study. Registries were searched using the following MeSH terms: ‘minimally invasive’, ‘muscle-sparing’, ‘THA’, ‘THR’, ‘hip arthroplasty’ and ‘hip replacement’. Locations searched included PubMed, the Cochrane Library, ClinicalTrials.gov, the EU clinical trials register and the International Clinical Trials Registry Platform (World Health Organisation). Twenty studies were identified. There were 1,282 MI THAs and 1,351 conventional THAs performed. (1). There was no difference between MI and conventional approaches for all clinical outcomes of relevance including all-cause revision (p=0.959), aseptic revision (p=0.894), instability (p=0.894), infection (p=0.669) and periprosthetic fracture (p=0.940). (2). There was also no difference in functional outcome at early or intermediate follow-up between the two groups (p=0.38). (3). In level I studies exclusively, random-effects meta-analysis demonstrated no difference in the rate of aseptic revision (p=0.461) between both groups. Intermuscular MI approaches are equivalent to conventional THA approaches when considering all-cause revision, aseptic revision, infection, dislocation, fracture rates and functional outcomes. Meta-analysis of level 1 evidence supports this claim

Hamstring grafts have been associated with reduced strength, donor site pain and muscle strains following Anterior Cruciate Ligament Reconstruction (ACLR). Traditional graft fixation methods required both semitendinosus and gracilis tendons to achieve a graft of sufficient length and diameter, but newer techniques allow for shorter, broad single tendon grafts. This study seeks to compare the outcomes between Single Tendon (ST) and Dual Tendon (DT) ACLR, given there is no prospective randomised controlled trial (RCT) in the literature comparing outcomes between these options. In this ongoing RCT: (ANZ Clinical Trials Registry ACTRN126200000927921) patients were recruited and randomised into either ST or DT groups. All anaesthetic and surgical techniques were uniform aside from graft technique and tibial fixation. 13 patients were excluded at surgery as their ST graft did not achieve a minimum 8mm diameter. 70 patients (34 ST, 36DT) have been assessed at 6 months, using PROMS including IKDC2000, Lysholm and Modified Cincinnati Knee, visual analog scale for pain frequency (VAS-F) and severity (VAS-S), dedicated donor site morbidity score, KT-1000 assessment, and isokinetic strength. Graft diameters were significantly lesser in the ST group compared to the DT group (8.44mm/9.11mm mean difference [MD],-0.67mm; P<0.001). There was a significant and moderate effect in lower donor site morbidity in the ST group compared to the DT group (effect size [ES], 0.649; P = .01). No differences between groups were observed for knee laxity in the ACLR limb (P=0.362) or any of the patient-reported outcome measures (P>0.05). Between-group differences were observed for hamstrings strength LSI favouring the ST group, though these were small-to-moderate and non-significant (ES, 0.351; P = .147). ST (versus DT) harvest results in significantly less donor site morbidity and this is the first prospective RCT to determine this. There were no differences between ST and DT hamstring ACLR were observed in PROMs, knee laxity and hamstring strength. Younger female patients tend to have inadequate single tendon size to produce a graft of sufficient diameter, and alternative techniques should be considered. Further endpoints include radiological analysis, longer term donor site morbidity, revision rates and return to sport and will continue to be presented in the future

Osteoarthritis (OA) is the most common form of arthritis and one of the ten most disabling diseases in developed countries. Total joint replacement (TJR) is considered by far as the most effective treatment for end-stage OA patients. The majority of patients achieve symptomatic improvement following TJR. However, about 22% of the TJR patients either do not improve or deteriorate after surgery. Several potential non-genetic predictors for the TJR outcome have been investigated. However, the results were either inconclusive or had very limited predictive power. The aim of this study was to identify genetic variants for the poor outcome of TJR in primary OA patients by a genome-wide association study (GWAS). Study participants were total knee or hip replacement patients due to primary OA who were recruited to the Newfoundland Osteoarthritis Study (NFOAS) before 2017. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) was used to assess pain and functional impairment pre- and 3.99±1.38 years post-surgery. Two non-responder classification criteria were used in our study. One was defined by an absolute WOMAC change score. Participants with a change score less than 7/20 points for pain were considered as pain non-responders; and those with less than 22/68 points for function were classified as function non-responders. The second one was the Outcome Measures in Arthritis Clinical Trials and the Osteoarthritis Research Society International (OMERACT-OARSI) criteria. Blood DNA samples were genotyped using the Illumina GWAS microarrays genotyping platform. The quality control (QC) filtering was performed on GWAS data before the association of the genetic variants with non-responders to TJR was tested using the GenABEL package in R with adjustment for the relatedness of the study population and using the commonly accepted GWAS significance threshold p < 5*10. −8. to control multiple testing. In total, 316 knee and 122 hip OA patients (mean age 65.45±7.62 years, and 58% females) passed the QC check. These study participants included 368 responders and 56 non-responders to pain, and 364 responders and 68 non-responders to function based on the absolute WOMAC point score change classification. While 377 responders and 56 non-responders to pain, and 366 responders and 71 non-responders to function were identified by the OMERACT-OARSI classification criteria. Interestingly, the same results were obtained by both classification methods, and we found that the G allele of rs4797006 was significantly associated with pain non-responders with odds ratio (OR) of 5.12 (p<7.27×10. -10. ). This SNP is in intron one of the melanocortin receptor 5 (MC5R) gene on chr18. This gene plays central roles in immune response, pain sensitivity, and negative regulation of inflammatory response to antigenic stimulus. The A allele of rs200752023 was associated with function non-responders with OR of 4.41 (p<3.29×10. -8. ). The SNP is located in intron three of the RNA Binding Fox-1 Homolog 3 (RBFOX3) gene on chr17 which has been associated with numerous neurological disorders. Our data suggested that two chromosomal regions are associated with TJR poor outcomes and could be the novel targets for developing strategies to improve the outcome of the TJR

Aims

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

Methods

A total of 11 databases were searched. A subset of studies published between 1 October 2020 and 1 January 2011 from a larger review mapping research on limb reconstruction and limb amputation for the management of lower limb COM were eligible. All outcomes were extracted and recorded verbatim. Outcomes were grouped and categorized as per the revised Williamson and Clarke taxonomy.

Aims

Bone demonstrates good healing capacity, with a variety of strategies being utilized to enhance this healing. One potential strategy that has been suggested is the use of stem cells to accelerate healing.

Methods

The following databases were searched: MEDLINE, CENTRAL, EMBASE, Cochrane Database of Systematic Reviews, WHO-ICTRP, ClinicalTrials.gov, as well as reference checking of included studies. The inclusion criteria for the study were: population (any adults who have sustained a fracture, not including those with pre-existing bone defects); intervention (use of stem cells from any source in the fracture site by any mechanism); and control (fracture healing without the use of stem cells). Studies without a comparator were also included. The outcome was any reported outcomes. The study design was randomized controlled trials, non-randomized or observational studies, and case series.

The aim of this study was to review the role of clinical trial networks in orthopaedic surgery. A total of two electronic databases (MEDLINE and EMBASE) were searched from inception to September 2013 with no language restrictions. Articles related to randomised controlled trials (RCTs), research networks and orthopaedic research, were identified and reviewed. The usefulness of trainee-led research collaborations is reported and our knowledge of current clinical trial infrastructure further supplements the review. Searching yielded 818 titles and abstracts, of which 12 were suitable for this review. Results are summarised and presented narratively under the following headings: 1) identifying clinically relevant research questions; 2) education and training; 3) conduct of multicentre RCTs and 4) dissemination and adoption of trial results. This review confirms growing international awareness of the important role research networks play in supporting trials in orthopaedic surgery. Multidisciplinary collaboration and adequate investment in trial infrastructure are crucial for successful delivery of RCTs.
