Functional outcome of delayed surgical fixation of capitellar fractures treated by open reduction and internal fixation with herbert screw

Introduction: Capitellar fractures are rare injuries and difficult to manage, especially so if the patient presents late. Treatment is almost always operative. The purpose of this study is to evaluate the functional outcome of capitellar fractures in adults treated by open reduction and internal fixation (ORIF) with cannulated compression headless screws (Herbert screw) with an inadvertent delay of 2 weeks or more. Materials and Methods: Twelve patients (4 males and 8 females) of capitellum fracture who were reported after an inadvertent delay of at least 2 weeks, with near-normal elbow range of motion, operated by ORIF with Herbert screw, were studied retrospectively from April 2013 to March 2019. All cases were operated between 2 to 3 weeks of injury. All patients had a follow-up for a mean period of 34 months, and the final functional outcome was assessed using Mayo Elbow Performance Index (MEPI) and by radiology. Results: The mean MEPI score was 92.9 points, and as per this evaluation of the functional rating, all but one patient had excellent results. The mean range of elbow flexion/extension was 125 (90–140), while the range of movement in supination/pronation was 170 (130–180). Conclusion: ORIF of capitellum fractures with Herbert screw was found to be superior and gives excellent result, even with a delay of around 2 weeks. Preoperative computed tomography is helpful not only to know clear picture of fracture configuration but also to choose right surgical approach and right implant. Apart from stable internal fixation, early mobilization and rehabilitation are the keys for optimum functional outcome.
