INTRA-ARTICULAR DISTAL RADIUS FRACTURES: FLUOROSCOPIC OR ARTHROSCOPIC REDUCTION?

7th Congress of the European Federation of National Associations of Orthopaedics and Traumatology, Lisbon - 4-7 June, 2005



Abstract

Purpose: Arthroscopy offers a view of intra-articular pathology, but its use in the treatment of intra-articular distal radius fractures remains controversial. This study compares functional and radiologic outcomes of arthroscopically assisted (AA) versus fluoroscopically assisted (FA) reduction and external fixation (EF) of distal radius fractures.

Type of study: double randomised prospective, comparison of 2 different procedures.

Methods: Between January 2000 and December 2003, 20 patients with comminuted intra-articular distal radius fractures underwent AA EF and percutaneous pinning and 20 patients underwent and FA EF reduction and pinning.

Results: Follow-up period was 9–27 months. Evaluation was clinical (grip strength, range of motion) and radiographic (palmar tilt, radial shortening, stepoff). The Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire and the MAYO wrist score were used 3-9-12 months postoperatively. In 9/20 patients of AA group the subchodral pins were changed after artrhroscopic view because of stepoff. The following tears were found: TFCC (12 of 20 patients), SL (9/20), LT (4/20). Patients who underwent AA surgery had significantly better supination; wrist extension; and flexion compared with the FA surgery group (86 vs 75; 76 vs 65; and 76 vs 63 degrees respectively). Radial shortening and DASH scores were better for the AA group compared to the FA group (AA:12, FA:25) the 3rd and 6th postoperative month but the difference decreased after the 12th month.

Conclusions: A reduction and fixation of intra-articular distal radius fractures provides improved inspection of the ulnarsided components of the injury. Long term evaluation revealed that patients with AA procedures returned in decreased periods to their previous activities (based on DASH score) and had better of supination, flexion, and extension than patients with FA surgery.
