OBJECTIVES The aim of this comparative effectiveness study was to perform a meta-analysis of adverse events and outcomes in closed geriatric olecranon fractures, without elbow instability, after treatment with surgical or nonoperative management. DATA SOURCES PubMed, Web of Science, and Embase databases. STUDY SELECTION Articles were included if they contained clinical data evaluating outcomes in patients ≥65 years of age with closed olecranon fractures, without elbow instability, treated surgically, or with nonoperative management. DATA EXTRACTION Data regarding patient age, olecranon fracture type, fracture union, adverse events, reoperation, elbow range of motion, and surgeon and patient reported outcome measures were recorded according to intervention. The interventions included for analysis were tension band wire (TWB) fixation, plate fixation, or nonoperative management. DATA SYNTHESIS Separate random effects meta-analyses were conducted for each outcome according to intervention. Prevalence and 95% confidence intervals (CI) were calculated for dichotomous variables, while weighted means and CI were calculated for continuous variables. CONCLUSIONS Comparable outcomes were achieved with surgical or nonoperative management of olecranon fractures in geriatric patients. Surgical intervention carried a high risk of reoperation regardless of whether plate or TBW fixation was used. Functional nonunion can be anticipated if nonoperative treatment is elected in low-demand elderly patients. LEVEL OF EVIDENCE Therapeutic Level IV.
