Dynamic External Fixation for Complex Intraarticular Phalangeal Fractures

Abstract

Intraarticular phalangeal fractures are difficult to treat. The advantages of using dynamic external fixation devices include distraction of impacted fracture fragments and reduction in joint stiffness by allowing early joint mobilization. Previous reports have concentrated on pilon fractures and dorsal fracture dislocations affecting the proximal interphalangeal joint. We report our experience using a dynamic external spring fixator in the management of 15 patients with a variety of fracture patterns affecting the metacarpophalangeal, proximal interphalangeal and distal interphalangeal joints. In three cases the device spanned two adjacent joints. Long-term follow-up has shown excellent range of joint movement and no major complications. We consider that this device is an effective tool in the management of a range on complex intraarticular phalangeal fractures.
