Complications in humeral shaft fractures - non-union, iatrogenic radial nerve palsy, and postoperative infection: a systematic review and meta-analysis.

ABSTRACT: The aim of this systematic review and meta-analysis was to assess risk for iatrogenic radial nerve palsy (iRNP), non-union, and post-operative infection in humeral shaft fractures. A PubMed search including original articles comparing different treatments for humeral shaft fractures published since January 2000 was performed. Random effect models with relative risks (RR) and 95% CIs were calculated for treatment groups and outcomes. Of the 841 results, 43 studies were included in the meta-analysis (11 level II, 5 level III, 27 level IV). Twenty-seven compared intramedullary nailing (IM) with ORIF, nine conservative with operative treatment, four ORIF with minimally invasive plate osteosynthesis (MIPO), and three anterior/anterolateral with posterior approach. iRNP risk was higher for ORIF vs IM (18 studies; RR: 1.80; P = 0.047), ORIF vs MIPO (4 studies; RR: 5.60; P = 0.011), and posterior vs anterior/anterolateral approach (3 studies; RR: 2.68; P = 0.005). Non-union risk was lower for operative vs conservative therapy (six studies; RR: 0.37; P < 0.001), but not significantly different between ORIF and IM (21 studies; RR: 1.00; P = 0.997), or approaches (two studies; RR: 0.36; P = 0.369). Post-operative infection risk was higher for ORIF vs IM (14 studies; RR: 1.84; P = 0.004) but not different between approaches (2 studies; RR: 0.95; P = 0.960). Surgery appears to be the method of choice when aiming to secure bony union, albeit risk for iRNP has to be considered, particularly in case of ORIF vs IM or MIPO, and posterior approach. Due to the limited number of randomised studies, evidence on the best treatment option remains moderate, though.

Project description:ObjectivesThis study was performed to determine (1) the incidence of humeral shaft fractures within the Medicare noncancer population, (2) the trends in utilization of humeral shaft fixation techniques by plate-and-screw devices and intramedullary nails, (3) differences in procedure times, and (4) the outcomes of individuals as measured by rate of secondary operations and 1-year mortality.Design/settingRetrospective comparative cohort analysis. A cancer-free Medicare part B claims sample derived from a 5% sample from the years 1993 to 2007 was analyzed.Patients/interventionOur cohorts were generated by diagnostic and procedural codes for humeral shaft fractures.Main outcome measurementThe incidence of humeral shaft fracture and trend in operative fixation were evaluated for all years of data. Surgical times were assessed by anesthesia Current Procedural Terminology codes. Outcomes and complications were assessed by Current Procedural Terminology codes. The proportion of individuals experiencing complications and 1-year mortality were compared by proportion hazards.ResultsWe identified 1385 claims for humeral shaft fractures over 15 years, with an adjusted rate of between 12.0 and 23.4 fractures per 100,000 beneficiaries. We identified 511 individuals who received surgical treatment for humeral shaft fractures, 451 of whom had complete 1-year follow-up data. Nail fixation was more prevalent than plate fixation most years and had shorter anesthesia time by 27.1 minutes (P < 0.0001). There were no significant differences in the complication rates between the 2 groups as measured by incidence of secondary operations and 1-year mortality.ConclusionsIntramedullary nails are used for the majority of operative humeral shaft fractures among Medicare beneficiaries. Nailing has a shorter mean operative time. The 2 surgical techniques had no significant differences in terms of risk of secondary procedures and 1-year mortality.Level of evidence: Prognostic Level II.
