This study suggests that the subluxation ratio method is the most useful technique for measuring translation of the distal radioulnar joint as a result of its reliability and simplicity. Substantial variations in normal values derived with the current methods should be considered in a computed tomography evaluation of the distal radioulnar joint in symptomatic patients.

PURPOSE: The purpose of this study was to review clinical and radiographic outcomes of perilunate dislocations and fracture-dislocations treated with arthroscopic reduction and percutaneous fixation. METHODS: Twenty patients who had an acute dorsal perilunate dislocation or fracture-dislocation were treated with an arthroscopic technique at a median interval of 3.9 days from the time of injury. They were retrospectively reviewed at a mean follow-up of 31.2 months (range, 18 to 61 months). Range

Perilunate injuries are severe disruptions of the wrist joint that produce variable patterns of injury to the carpal anatomy. Most surgeons advocate an open reduction followed by ligament repair or internal fixation. We tried to reduce and fix the carpal bones under arthroscopic control to minimize surgical trauma and to preserve blood supply. While viewing the articular surface with the arthroscope, the disrupted proximal carpal row was anatomically reduced using Kirschner wires as joysticks, a

This study presents our technique of arthroscopic scaphoid excision and four-corner arthrodesis and compares the clinical and radiological outcomes with those achieved with the open method. Twenty-seven patients (14 in arthroscopy group and 13 in open group) were included. Bone union was achieved in 13 of 14 patients in the arthroscopy group and in all 13 patients in the open group. In the open group, severe stiffness (flexion–extension arc was 10°) occurred in one patient after surgery. The mea

The purpose of this study was to test the hypothesis that an improved outcome can be achieved by employing simultaneous steroid injection after percutaneous A1 pulley release. One hundred and twelve digits were randomized to either percutaneous A1 pulley release alone or release of the A1 pulley with a steroid injection. The visual analogue scale score for pain, modified patient global impression of improvement and modified Quinnell grade were assessed at 3 weeks and 3 months after surgery. At 3

Purpose : This study examined the clinical usefulness of a pedicled vascularized bone graft for the treatment of a scaphoid nonunion. Materials and Methods : Twenty-one patients with a scaphoid nonunion were treated with a pedicled vascularized bone graft using the 1, 2 intercompartmental supraretinacular branch of the radial artery. The average age of the patients was 29.3 years (range, 16-47) and the mean follow-up period was 19.6 months (range, 12-36). Punctate bleeding of the proximal fragme
