Isolated injuries to the dorsoradial capsule of the thumb metacarpophalangeal joint.

Isolated injuries to the dorsoradial capsule of the thumb metacarpophalangeal joint are rarely reported. We report 11 patients who had a tear in the dorsoradial capsule of the thumb metacarpophalangeal joint without an associated collateral ligament injury. Seven of the injuries were confirmed at surgical exploration and repaired by imbrication/direct repair. Six of these seven patients were able to return to unrestricted activities without requiring analgesics. The surgical patients had increased baseline metacarpophalangeal joint flexion compared to "average," which may predispose them to isolated capsular injuries.

Median nerve compression in the proximal forearm.

Thirty-nine limbs in 36 patients underwent surgical decompression of the median nerve in the proximal forearm. Seventeen patients with 19 limbs had prior ipsilateral carpal tunnel releases, and 24 had workers' compensation claims related to heavy labor or repetitive tasks. The most common presenting complaints were paresthesias/numbness in the distribution of the median nerve and pain in the forearm or hand. The most common physical finding was a positive pronator compression test, followed by median nerve hypesthesia. Elbow to wrist nerve conduction tests were obtained in 37 of 39 limbs and were abnormal in 12. Intraoperatively, the nerve was compressed at the flexor digitorum superficialis tendon in 22 limbs, pronator teres in 13 limbs, and both in 4 limbs. Postoperatively, 30 limbs had complete or partial relief of symptoms; in a sub-group of 19 limbs that had a prior failed carpal tunnel release, 14 had complete or partial relief. Although there was a trend toward better results in patients with normal preoperative nerve conduction tests and intraoperative compression at the flexor digitorum superficialis, the difference was not significant.

Scaphocapitolunate arthrodesis.

Since 1985 scaphocapitolunate arthrodesis has been performed on 21 patients with either chronic incompetence of the scapholunate ligament or a scaphoid nonunion. The average age was 31 years; follow-up averaged 28 months. Eighty-six percent of the injuries involved workers' compensation. The operative procedure was done through a dorsal approach, with the use of autogenous bone grafting and Kirschner wire fixation. Eight-one percent healed after the primary procedure; one patient had a major infection. Range of motion averaged 35 degrees of extension, 30 degrees of flexion, 10 degrees of radial deviation, and 20 degrees of ulnar deviation. Grip strength averaged 70% of the uninvolved side. Pain was significantly reduced in 80% of the patients. Sixteen of 20 patients were able to return to work. Radiographic examination at final follow-up showed mild degenerative changes at the radiocarpal joint in two patients.
