Sauvé-Kapandji and Darrach Salvage Procedure Rates and Perioperative Parameters for Distal Radioulnar Joint Arthritis and Instability

Abstract

Background:

Distal radioulnar joint (DRUJ) instability and arthritis are often painful and functionally limiting pathologies. Two common salvage procedures for DRUJ dysfunction are the Darrach and Sauvé-Kapandji (S-K) procedures. This study aims to provide an analysis of national Darrach and S-K procedure utilization rates and patient demographics.

Methods:

A national ambulatory surgery database, the 2018 Nationwide Ambulatory Surgery Sample, was filtered for Darrach and S-K procedure encounters. Data related to patient demographics and medical history, indications for DRUJ salvage, and concurrent hand/wrist procedures were collected.

Results:

Database analysis revealed 1044 Darrach and 223 S-K procedure encounters. Patients undergoing Darrach procedures were older (60 vs 57, P = .002) and more likely to be women (66.1% vs 54.6%, P < .05). Patients aged <35 years underwent S-K procedures at greater rates compared with Darrach (13.9% vs 8.6%, P < .05). Primary osteoarthritis proved to be the most common indication for DRUJ salvage (64.8%) compared with rheumatoid arthritis (23.2%) and post-traumatic osteoarthritis (12.0%). Darrach and S-K procedures were accompanied by a secondary procedure at rates of 64% and 41%, respectively. The most common secondary procedures were tendon transfer, implant removal, neuroplasty, nerve resections, and wrist arthroscopy.

Conclusions:

Patient age and sex are associated with DRUJ salvage procedure selection. Sauvé-Kapandji procedures are used in higher rates in male and younger patient populations. Furthermore, primary osteoarthritis and rheumatoid arthritis are the main underlying pathologies for Darrach and S-K procedures.
