Eight patients with suspected diagnosis of distal radioulnar joint (DRUJ) subluxation underwent computed tomographic (CT) scans of the wrist. Five underwent surgery and had DRUJ subluxation or dislocation; CT scans revealed subluxation in four. Three CT criteria for the evaluation of DRUJ subluxation are discussed and compared in this manuscript.
The scapho-lunate distance was measured on posteroanterior radiographs of 100 normal wrists. The scapho-lunate distance measured a mean of 3.7 mm +/- SD 0.6 (range from 2.5 to 5.0 mm). The mean for 44 male wrists was 4.0 mm, and for 56 female wrists it was 3.6 mm. These results indicate that a scapho-lunate distance of up to 5 mm is not necessarily(More)
One hundred and fifty fingers in 136 patients were treated by a two-stage flexor-tendon reconstruction and followed for an average of 2.4 years. A salvage procedure such as this was needed for most of these fingers since 81 per cent of the injuries were in Zone 2 and 45 per cent were Grade 5 in severity. Before reconstruction, the mean total active motion(More)
Twenty-four patients (24 wrists) with ulnar impaction syndrome underwent ulnar shortening osteotomy. They were reviewed retrospectively to evaluate a technique using the AO small distractor and 2.7-mm dynamic compression plate. A transverse osteotomy using an external compression device and compression plating was performed in all cases. The average(More)
A normal radionuclide bone image can facilitate distinction between a bone island and significant pathologic processes, especially an osteoblastic metastasis. This distinction becomes more crucial when growth is detected in an isolated sclerotic bone lesion or if a relatively large sclerotic lesion is detected de novo in patients with a known neoplasm.

Each of 480 extremities from 120 cadavers was dissected. Particular attention was given to potential donors for tendon grafts. Both the palmaris longus and the extensor digiti minimi had an average length of 16 cm and an average width of 3 mm. The extensor indicis tendon averaged 13 cm in length and 3 mm in width. The plantaris and second toe extensors(More)
We studied normal hand strength and the difference between dominant and nondominant hands. Two hundred fourteen volunteers were tested with a calibrated Jamar dynamometer at all five levels. A pinch gauge was used to assess key and pulp pinch. Height, weight, sex, hand dominance, and hobby demands were predictive of maximum grip. Mean maximum grip for women(More)
Thirty hands with 50 extensor tendon lacerations, excluding mallet finger injuries, were examined. They were treated with surgical repair followed by immediate motion which included a dynamic splinting and tendon mobilization program. The average follow-up period was 7 months (range, 8 weeks to 2 years). Forty-five of the 50 tendons regained full range of(More)
