[Initial experiences with a new wrist joint fixator in treatment of distal radius fractures]

Abstract

Between January 1989 and October 1991, 56 patients with 57 distal radius fractures were treated with the new Orthofix wrist fixator. This review of 43 patients consists of cases with follow-ups of at least 12 months. One patient had died, and 38 (90.5%) of the remaining 42 fractures were examined 20.3 months after surgery, on average. Radiological findings were classified according to Lidström, and the functional results according to Gartland and Werley in the Sarmiento modification. Functional analysis demonstrated excellent and good results in 73% of the fractures. Although the number of cases studied is too small for statistical analysis, the results do show a trend emphasizing the importance of subtle anatomical restoration, particularly of the radial length. Since this cannot always be obtained by external fixation alone, supplementary Kirschner-wires, screws and bone-grafting can be necessary. The main advantages of the new Orthofix fixator are its light-weight design, simple application, and the possibility of fracture reduction even after the device has been mounted. Early mobilisation has not been evaluated sufficiently, so no general recommendations can be made yet.
