Abstract

Dorsal dislocation of the proximal interphalangeal joint is a common injury in the orthopedic department. In most cases, the joint is reduced simply by closed manipulation. However, in rare cases, the joint is not reducible by closed manipulation, therefore, surgery is required. We report on a case of irreducible open dorsal dislocation of the proximal interphalangeal joint which was surgically treated. Because the flexor tendon interposed between the head of the proximal phalanx and the base of the middle phalanx, we could reduce the joint only after repositioning of the flexor tendon.

Keywords: Irreducible dislocation, Proximal interphalangeal joint, Flexor tendon

Figures and Tables

Fig. 1

Radiographs showed the dorsoulnar dislocation of the proximal interphalangeal joint.

Fig. 2

Preoperative magnetic resonance imagings. The flexor digitorum profundus tendon interposed between the head of the proximal phalanx and the base of the middle phalanx. (A) Sagittal images. (B) Coronal images.

Fig. 3

Intraoperative photographs. (A) The head of the proximal phalanx protruded through the palmar open wound. (B) Flexor digitorum profundus tendon (black arrow head) had slipped behind the condyle of the proximal phalanx.

Fig. 4

Postoperative radiographs showed well-reduced state of the proximal interphalangeal joint.

Fig. 5

At six months after the operation, there was mild swelling at the proximal interphalangeal joint. However, the patient regained a nearly normal range of motion.
