Chung, Kang, Hwang, Kim, Kim, and An: Irreducible Dislocation of the Interphalangeal Joint of the Thumb: A Case Report

Abstract

Dislocations of the interphalangeal joint of the thumb are rather uncommon as a result of the inherent stability of the interphalangeal joint. Irreducible dislocations of these joint are rare. The authors report a case of irreducible dislocation of the interphalangeal joint of the thumb with interposed palmar plate, and reduced by open reduction.

Figures and Tables

Fig. 1

Preoperative anteroposterior (A) and lateral (B) X-ray of the thumb show dorsal dislocation of interphalangeal joint and old avulsion fracture of the base of the proximal phalanx.

Intraoperative photograph showing extracted palmar plate from interphalangeal joint (forceps). The palmar plate was interposed in the joint still attached to the base of the distal phalanx.

Postoperative anteroposterior (A) and lateral (B) X-ray show reduced interphalangeal joint and temporary interphalangeal joint fixation with K-wire.

At postoperative 6 months, the anteroposterior (A) and lateral (B) X-ray show good joint space and restoration of articular congruity.
