Humeral shaft fracture: a randomized controlled trial of nonoperative versus operative management (plate fixation).

Abstract

PurposeThis randomized controlled trial was conducted to investigate the outcomes of humeral shaft–fracture management with the functional Sarmiento brace (nonoperative) versus open reduction internal fixation (ORIF).MethodsSixty humeral shaft–fracture patients with a minimum age of 18 years were randomly assigned into two groups: operative treatment with open reduction–internal fixation (ORIF) or functional brace (Sarmiento). A similar postoperative rehabilitation program was applied for all subjects for the next 12 months. The outcomes of each method were measured in terms of nonunion rate, union time, “quick” Disabilities of Arm, Shoulder, and Hand (DASH) questionnaire scores, and rate of complications, such as malunion, infection, and radial nerve injury.ResultsThe two groups had similar baseline characteristics, including age, sex, smoking status, and type and mechanism of fracture. The mean union time was about 4.8 weeks shorter in the ORIF group (13.9 weeks in operative group versus 18.7 weeks in nonoperative group), indicating a definite significant superiority (p=0.001) of ORIF management to functional Sarmiento bracing. However, a comparison of quick DASH scores revealed a borderline-significant difference between the groups (p=0.065). Additionally, we found that treatment of humeral shaft fractures using functional bracing was associated with slightly higher risk of nonunion; however this was not significant (p=0.492).ConclusionAccording to the present findings, there is remarkable superiority of ORIF over functional Sarmiento bracing in the management of patients with humeral shaft fracture.
