Clinical Outcomes of Arthroscopic-Assisted Volar Scapholunate Capsulodesis: A Case Series.

Abstract

Purpose  We have previously described arthroscopic-assisted volar scapholunate (SL) capsulodesis as an alternative technique for addressing volar SL interosseous ligament (SLIL) injuries. In this article, we report the outcomes of this procedure in a cohort of patients. Methods  Postoperative outcomes including range of motion, grip strength, visual analog scale (VAS) pain score, Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH), and Mayo Wrist Score were assessed through a prospective review of six patients in a single center who underwent this procedure. Results  Six patients (four male and two female) with a mean age of 43 ± 14 years were evaluated in the study. The mean duration of follow-up was 41 ± 17 weeks. Postoperative outcomes noted a reduction in VAS pain score from 8 before surgery to 0.7 postoperatively ( p  = 0.00004) and improvement in Mayo Wrist Score (42 preoperatively to 80 postoperatively; p  = 0.001), grip strength (86% of contralateral side; p  = 0.20), and flexion arc (81% of contralateral side; p  = 0.08). QuickDASH was 20 ± 8 and Patient-Rated Wrist Evaluation score was 13 ± 2 at the last clinical follow-up. There was an improvement in SL gap ( p  = 0.03), SL angle ( p  = 0.11), and radiolunate angle ( p  = 0.15) measurements postoperatively. Conclusions  The described arthroscopic-assisted volar SL capsulodesis in this study presents an alternative method to address volar SLIL pathology with positive short-term clinical outcomes. Clinical Relevance  Arthroscopic-assisted volar SL capsulodesis may be considered in the treatment algorithm for volar SLIL injuries.
