Abstract

Irreducible closed dorsal dislocation of distal interphalangeal (DIP) joint of the finger is a rare injury. The causes of irreducibility of the DIP joint are volar plate interposition, entrapment of flexor digitorum profundus tendon behind the head of middle phalanx, and buttonholing of the middle phalanx head through the volar plate or flexor tendon. Open reduction with a volar approach is recommended with the advantages of better wound healing, ease of releasing entrapped structures, and possibilities of a volar plate, collateral ligaments, and/or flexor tendon repair. We report a case of irreducible dorsal dislocation of left ring finger DIP joint secondary to volar plate interposition treated successfully with open reduction.

Summary

Introduction

Dislocations of the finger distal interphalangeal (DIP) joint are rare injuries due to its inherent stability provided by flexor and extensor tendon insertions, strong volar plate and collateral ligaments, and short lever arm of distal phalanx [1]. It is usually encountered in open injuries and reduction is easy in most of the cases with simple maneuver. He underwent open reduction and k-wire fixation of the left ring finger DIP joint via volar approach (Figure 2A). Good functional range of motion of the left ring finger distal interphalangeal joint in extension (A) and flexion (B)
