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.

Fig. 2
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.
