Abstract
Approximately, 7% of all adult fractures involve the elbow, of these one third (2%) are distal humeral fractures. Articular fractures of elbow are the most difficult one to treat. Because of their complex anatomy, proximity to vital structures, injury patterns, associated osteoporosis in elderly patients and limited space for instrumentation. As far as we know, no previous meta- analysis study has investigated the privilege between olecranon osteotomy and triceps-reflacting anconeous pedicle (TRAP) regarding functional outcome and complications in the treatment of suprachondylar and interchondylar humerus fractures. Therefore, we performed this systematic review and meta-analysis study of this issue.
This meta-analysis study included all studies which comparing between TRAP and OO in the treatment of suprachondylar and interchondylar humerus fractures.
The literature search was in the Web of Science, PubMed, Scopus, and Cochrane databases using advanced search strategy. The search results was screened using titles and abstracts then full paper.
The following data were extracted: country, study design, sample size, baseline characters of included patients, intervention, outcomes, parameters measuring functional outcome as incidence of excellent and good elbow performance, Mayo elbow performance score, duration of operation, blood loss and, complications.
The quality assessment was operated by ROBINS-I tool for assessment of risk of bias for non-randomized studies, cohort studies and the Cochrane RoB tool for randomized trials.
All statistical analyses was operated using RevMan. The overall effect size were estimated as mean difference (MD) and 95% confidence interval (95% CI) for continuous data or as odds ratio and 95% CI for dichotomous data using a fixed-effect model in the absence of heterogeneity ( I2 ≤ 50%; p > 0.1) otherwise, the random effect model were operated.
Subgroup analyses, sensitivity analysis was conducted to explore possible sources of heterogeneity. The potential publication bias was assessed by visual inspection of the funnel plots.
