Individual Joint Distractions Using Ilizarov Mini-Fixator Device for Chronic Simultaneous Dislocation of the Distal and Proximal Interphalangeal Joints in the Same Finger.

Abstract

Simultaneous dislocation of the distal and proximal interphalangeal joints is an uncommon injury. Treating chronic cases proves challenging due to severe contractures affecting both joints and surrounding soft tissues. Here, we report an unusual chronic contracture case in a 46-year-old man who suffered a dorsal dislocation of the distal and proximal interphalangeal joints of the little finger. The patient underwent primary joint distraction followed by open reduction, leading to stable radiographic restoration and a functional range of motion in the affected finger 6 months postoperatively. Joint distraction was a reliable approach for the treatment of chronic joint dislocation with severe soft tissue contracture, especially for multiple joint contractures. In addition, the Ilizarov mini-fixator device was effective in enabling individualized traction on both the distal and proximal interphalangeal joints.
