Abstract: | Introduction The majority of metacarpal fractures can be treated conservatively. Nevertheless, surgical treatment is justified in certain cases. Palmar dislocation of >30° and shortening of >5 mm will significantly affect extension and flexion of the hand. Consequently, surgical treatment is indicated. The aim of our study was to evaluate the clinical results of intramedullary Kirschner-wire fixation of metacarpal fractures.Material and methods In a retrospective study we analyzed the clinical results of 35 patients with metacarpal fractures that had been treated by closed reduction and elastic fixation with at least two intramedullary k-wires.Results Most of the patients were young, with good bone quality and low anesthetic risk, and they had suffered the fractures as a result of a direct trauma. Predominantly uncomplicated, the fractures were metaphyseal, subcapital and of the fifth metacarpal bone (750.3-B1 fractures). Surgical treatment was indicated for a palmar axis dislocation of >20° or if a rotatory deficiency was present. Metacarpal joint function and correction of rotatory displacement could be assessed on median after a period of 1.1 year. In 34 patients flexion and extension was normal on both sides. In one patient we found an extension deficiency of 15° and a rotatory deficiency of 10°. In 34 out 35 patients with metacarpal fractures, minimally invasive intramedullary k-wire osteosynthesis resulted in complete restoration.Conclusions Intramedullary k-wire fixation is a minimally invasive method for stabilizing metacarpal fractures. The excellent long-term clinical results are due to the fact that the gliding tissue around the fracture will not be affected at all by the surgical procedure.The study was performed at the department of traumatology, Klinik am Eichert, Göppingen, Germany |
