Hybrid Ilizarov External Fixator for Distal Radius Fractures

Background: Fractures of distal radius are common injuries. Unstable distal radius fractures present a challenge to the treating orthopaedic surgeon. One of the therapeutic methods is I1izarov hybrid external fixator. In this study short-term result of this method in a small group is reported. Methods: 18 consecutive patients with unstable fracture of distal radius were treated with non-bridging hybrid Ilizarov external fixator for 7 weeks. Clinical and radiological evaluation was performed at one and 7 days, and at 6 weeks and 6 months after surgery. Results: All fractures united but anatomic reduction was achieved in only 16 cases (90%) . The achieved range of motion was: 80% flexion, 85% extension and 90% supination and pronation. Compared to the normal side, no extensor tendon injury and tendonitis of pin loosening occurred. Only 5 mild pin track infection was observed that resolved by findings of oral antibiotic therapy. Conclusion: The technique of hybrid non bridging external fixator is safe and reliable option method for unstable intra and extra-articular distal radius fractures. It permits free wrist motion during treatment preventing joint stiffuess. Keywords: llizarov technique; Radius fractures; External fixator
