A prospective study of 15 cases of fifth metacarpal neck fractures treated by antegrade single blunt-tip k wire: Surgical technique, clinico-radiological outcome

Abstract

Introduction: Metacarpal fractures are among the most commonly treated upper extremity injuries in adults, and represent about 10% of all fractures. In this study we described a technique with antegrade pre bent blunt tip k wire fixation for 5th metacarpal neck fracture in 15 patients with good functional outcome. Methods: Our study was conducted Between January 2016 and June 2017. In our study 15patients with fifth metacarpal neck fracture underwent surgical treatment with antegrade blunt tip k wire. A single blunt tip k wire with suitable diameter was used in 15 cases of fifth metacarpal neck fractures with dorsal angulation over 30°. An entry point was taken at the ulnar-dorsal base of the 5th metacarpal. The k wire was inserted in an antegrade approach. The k-wire was usually removed at about 4 weeks postoperatively after clinic radiological signs of union. Results: At final follow up, all fractures proceeded to bony union. The mean total active motion (TAM) was 263°. Mean preop neck shaft angle is 54.2 (n=15), mean post op neckshaft angle is 9.4. mean dash score 2.7 was observed.. At 6 months follow up, all 15 patients had an excellent to good results and able to continue their routine work daily without any difficulty Conclusions: Antegrade intramedullary technique with pre-bent blunt-tip k wire is preferred as this method is technically simple, cost effective, less invasive, less perioperative complications, reproducible with excellent to good functional outcomes.
