    Abstract:
    BACKGROUND: Minimally invasive plate osteosynthesis for humeral shaft fractures has been described recently, but there are no randomized studies comparing the clinical results for shoulder function between this technique and locking intramedullary nailing. METHODS: A prospective randomized study was performed. Forty-one humeral shaft fractures (40 patients) were randomized to be treated with a minimally invasive plate (n = 21) or a locking intramedullary nail (n = 19). Clinical and radiographic outcome assessments were conducted at 1 year postoperatively. Shoulder function was the primary outcome, as measured by the University of California, Los Angeles Shoulder Scale. Elbow function was measured by the Broberg-Morrey score, and fracture consolidation and complications were the main secondary outcomes. RESULTS: At 1 year postoperatively, no significant difference was found with regard to shoulder function according to the University of California, Los Angeles scale between the minimally invasive plate and locking intramedullary nail (31.4 points vs 31.2 points, P = .98). There was also no difference in elbow function (94.8 points vs 94.1 points, P = .96). Complications were similar between the groups, without significant differences regarding infection (P > .99), symptomatic shoulder stiffness (P = .488), and neurapraxia of the lateral cutaneous nerve of the forearm (P = .475). Fracture union was achieved in all but 1 patient (2.4%) in the intramedullary nail group within 1 year after the surgical procedure. CONCLUSION: There is no significant difference in shoulder function between antegrade intramedullary nailing and minimally invasive plate osteosynthesis for the treatment of displaced humeral shaft fractures, despite the limited power of our study.
