Abstract

Purpose Scapholunate advanced collapse (SLAC) wrist results from an untreated scapholunate dissociation and is the most common type of degenerative arthritis of the wrist. The most common surgical treatments for SLAC wrist are proximal row carpectomy and four-corner fusion with scaphoid excision. Arthroscopic surgical treatment for SLAC wrist has been reported; however, only limited data on functional outcomes are available. The purpose of this study is to report our 5-year follow-up clinical outcomes for arthroscopic treatment for SLAC wrist.

Methods Thirty-one consecutive cases of arthroscopic resection arthroplasty for SLAC wrist were reviewed. Preoperative and postoperative Disabilities of the Arm, Shoulder, and Hand (DASH) scores, range of motion, grip strength, and pain (on 0–10 scale) as well as postoperative satisfaction (0 = not satisfied, 5 = completely satisfied) were recorded. Grip and range of motion were measured by an occupational therapist.

Results The preoperative pain score was 7 and 0.18 postoperatively. The mean satisfaction at final follow-up was 4.8. Preoperative and final follow-up scores of the mean DASH was 48 and 3, respectively. The total arc of motion was 114 degrees preoperatively and 126.5 degrees postoperatively. Mean grip strength before surgery was 41 and 49 kg at final follow-up.

Conclusion Arthroscopic resection arthroplasty for SLAC wrist results in significant improvement in patient function as measured by DASH and pain scores.

Type of Study/Level of Evidence Therapeutic IV.
