Irreducible trans-scaphoid perilunate dislocation.

Two cases of irreducible trans-scaphoid perilunate dislocation are described. In each case there was soft tissue interposition between the proximal and distal elements of the fracture-dislocation and this prevented capitolunate and scaphoid reduction. The dorsal capsule was impaled on the distal scaphoid fragment in one case, and a flap of dorsal capsule was entrapped between the capitate and the lunate in the other. In light of these findings, we recommend a dorsal approach for open reduction of trans-scaphoid perilunate dislocation when the capitolunate joint cannot be reduced by closed manipulation.

Bone injuries: treatment and rehabilitation.

Solid bony union with full range of painless motion is accomplished by correct early diagnosis, adequate reduction, stable fixation, prevention of edema, and institution of early motion programs. The degree of bony injury and involvement of multiple tissues will dictate the type of fixation and length of immobilization. Restoration of a stable skeleton with a functional range of joint motion must always be accomplished.

Avulsion of the profundus tendon insertion in athletes.

A review of 36 avulsions of the flexor profundus tendon insertion in athletes seen during the past 5 years showed the injury to be most common in the ring finger. The injury was classified into three types depending upon (1) the presence or absence of a bony fragment on roentgenograms, (2) the level to which the tendon retracted, and (3) the status of the blood supply of the avulsed tendon. If the tendon retracts into the palm at the time of injury, it should be repaired within 7 days. If the tendon retracts only to the proximal interphalangeal joint, it often can be repaired a few months after the injury. Late untreated patients who were relatively asymptomatic were left alone. Those with unstable distal interphalangeal joints were treated by fusion or tenodesis of the distal joint. A flexor tendon graft through an intact functioning superficialis tendon in the ring finger seldom was indicated. Prompt diagnosis and surgical repair within the first week gave the best results.
