Outcomes of Darrach and Sauvé-Kapandji Procedures: A Systematic Review

To review the available literature on Darrach and Sauvé-Kapandji (SK) procedures and perform a systematic review to identify differences in clinical outcomes. We hypothesized that SK would have a higher complication rate without significant clinical benefit.

A literature search was conducted using PubMed, EMBASE, Cochrane Library, and SCOPUS (from inception to January 2020) to identify studies evaluating outcomes of Darrach and SK procedures. Primary outcome measures included the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score, range of motion, grip strength, complications, and overall satisfaction.

A total of 103 articles were identified and screened, and of these, 44 full-text articles were used for data extraction and qualitative analysis. Outcomes were similar for QuickDASH scores, grip strength, and range of motion, as was overall satisfaction. Specifically, satisfaction rates for stabilized SK and Darrach procedures in patients without rheumatoid arthritis were comparable at 70.2% and 72.6%, respectively. Average QuickDASH scores were similar (21 for Darrach and 29 for SK). Mechanical symptoms due to stump instability occur with either procedure but were higher with the Darrach procedure (12.5% compared with 6.8%). The SK had more surgery-related complications such as nonunions (2.3%), symptomatic hardware, and reoperations (6.8% compared with 3.2%).

Both Darrach and SK procedures provide comparable satisfaction rates regardless of the underlying pathology. Improvement in range of motion, strength, and overall function is similar for both procedures; however, the reoperation rate is higher with SK.
