The Role of Arthroscopy in the Management of Wrist Arthritis

Arthroscopic Resection Arthroplasty for Scapholunate Advanced Collapse Wrist

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.

Arthroscopic Debridement and Arthrolysis for the Treatment of Advanced Kienböck's Disease: 18-Month and 5-Year Postoperative Results

Background  Salvage procedures, such as proximal row carpectomy, limited or total wrist arthrodesis, and wrist replacement, are generally preferred to treat advanced Kienböck's disease. However, these procedures are particularly aggressive and may have unpredictable results and potentially significant complications. Questions/Purpose  This study aimed to present the short- to mid-term clinical and functional results of arthroscopic debridement and arthrolysis in the management of advanced Kienböck's disease. Patients and Methods  Fifteen patients in whom Lichtman Stages IIIA to IIIC or IV Kienböck's disease was diagnosed and treated by arthroscopic wrist debridement and arthrolysis were included in this retrospective study. The mean age was 30 years (range: 21-45). The mean follow-up period duration was 36 months (range: 18-60). The Disabilities of the Arm, Shoulder, and Hand (DASH) score, visual analog scale (VAS), wrist range of motion (ROM), and grip strength were measured preoperatively and then again at the final follow-up visit. Results  The mean DASH and VAS scores improved from 41 (range: 31-52) and 7.1 (range: 6-8) preoperatively to 13 (range: 8-21) and 2 (range: 0-3; p  < 0.001) at the final follow-up visit, respectively. The mean wrist flexion and extension values increased from 32 (range: 20-60 degrees) and 56 degrees (range: 30-70 degrees; p  = 0.009) preoperatively to 34 (range: 10-65 degrees; p  = 0.218) and 57 degrees (range: 30-70 degrees; p  = 0.296) at the final follow-up appointment, respectively, although these findings were statistically insignificant. The mean strength of the hand grip increased from 22.7 (range: 9-33) to 23.3 (range: 10-34; p  = 0.372). Conclusion  Arthroscopic debridement and arthrolysis may improve wrist function and quality of life due to the preserved ROM and hand grip strength after short- to mid-term follow-up periods despite the radiographic progression of Kienböck's disease. Level of Evidence  This is a Level IV, retrospective case series study.
