Parallel-double-plate internal fixation technique in the treatment of distal humeral comminuted fracture in adults

Abstract

Objective To assess the effects of parallel-double-plate internal fixation on distal humeral comminuted fracture in adults.Methods Twenty consecutive adults with distal humeral comminuted fracture who received open reduction and internal fixation with parallel-double-plating at day 2 following bone facture between October 2006 and October 2009 were enrolled.Posterior elbow median incision was adopted for surgery.The functional exercise program commenced at day 3 postoperatively.The function of elbow was assessed by Mayo elbow performance score (MEPS),and the internal fixation and fracture healing by plain X-ray films.Results The 20 patients were followed up for 12 to 36 months [mean (18.4±2.0) months].Neither infection of incisions,nor nerve injury,or deformity of shortening,rotation,or implantation failure were found.The median MEPS was 86 points and the overall excellence rate was 85.3％ in the first year of follow-up.Conclusion The parallel-double-plate technique may facilitate early-stage solid fixation of distal humeral comminuted fracture and promote postoperative functional exercise of the affected extremity and joint rehabilitation.
