PURPOSE: Fractures of the radial shaft associated with disruption of the distal radioulnar joint (DRUJ) are termed as Galeazzi-fractures. In Galeazzi's fracture, the aim of treatment is restoring the congruency of the joint and the stability of the DRUJ, thus preventing a loss of pronation or supination. PATIENTS AND METHOD: In this study, we included 24 patients (m = 22, f = 2) with 25 Galeazzi fractures treated between 1980 and 1998. Surgical treatment and the duration of therapy were analyzed retrospectively. The clinical and radiological results of 15 patients were followed up. Two children were treated conservatively with immobilization in an above-the-elbow plaster. 19 patients were treated surgically by rigid internal fixation with a plate approximately one week after the accident. Four patients were treated initially in a different way. In 13 cases, the distal radioulnar joint was immobilized by pinning with Kirschner wires. In ten patients, the DRUJ showed no instability. Patients with DRUJ pinning received an above the elbow plaster for six weeks, the other patients received a forearm cast for the time of wound healing. RESULTS: Two patients developed a pseudarthrosis following Kirschner-wire or rush-pin osteosynthesis. The consolidation of remaining fractures was regular. In two patients, the DRUJ was not completely stable after temporary fixation. The remaining patients revealed a stable DRUJ. Eight patients showed a limited pro- or supination after temporary Kirschner wire fixation of the DRUJ. The other patients did not reveal a decrease in range of motion. CONCLUSION: A stable and optimal reduction and a rigid internal osteosynthesis are requisites for healing of the radius fracture. Open reduction of the DRUJ is only indicated when soft tissue interposition prevents exact reposition. Surgical revision of the distal radioulnar joint was not necessary in our patients. Patients after Kirschner-wire fixation showed a diminished pro- or supination. To prevent Kirschner-wire failure, postoperative cast immobilization is indicated. Due to the retrospective nature of the study it is not definitely clear if Kirschner wire fixation is superior to immobilization. DOI: 10.1055/s-2001-16587
