Anatomic relationships of an endoscopic carpal tunnel device to surrounding soft tissue structures along the ring finger and the long-ring interspace axis were investigated in 28 adult cadaver hands. The average distance from the center of the device to the median nerve in the carpal tunnel averaged 3.3 mm in the ring finger axis and 2.5 mm in the long-ring interspace axis. The average distance from the distal edge of the transverse carpal ligament to the superficial palmar arch was 4.8 mm in the ring finger axis and 5.5 mm in the long-ring interspace axis. These and other more subtle anatomic observations indicate the greater safety of using the ring finger axis for endoscopic carpal tunnel release.

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.

This study objectively investigated the functional results of 28 index finger pollicizations for correction of congenital deficiency of the thumb. The results indicate that the average total active range of motion at the pollicized digit was 98 degrees, or approximately 50% that of a normal thumb. The average grip strength was 21% of standard values; lateral, tripod, and tip pinch strength values ranged from 22% to 26% of standard values. The pollicized digit was used in the manner of a normal thumb or in modified fashion in 84% of 14 defined activities, with increased use for handling large objects (92%) and less use for small objects (77%). The time required to perform activities averaged 22% longer than the standard for a normal hand. Patients with a radial club hand, a five-finger hand, or a mirror hand on the affected extremity had significantly poorer results; however, patients without one of these associated conditions had near normal use of the pollicized digit, except for reduced strength. These results were not influenced by the age of the patient at the time of operation. This information should be helpful in counseling parents with children who are candidates for pollicization as to what functional results they might anticipate.
