Functional outcomes after modified Sauve-Kapandji arthrodesis for distal radioulnar joint dysfunction

Background The distal radioulnar joint (DRUJ) dysfunction manifests as pain, weakness and reduced range of motion. There are various treatments for DRUJ dysfunction. Modified Sauvé-Kapandji procedure involves arthrodesis of the distal radioulnar joint combined with the creation of a pseudarthrosis of the distal ulna to maintain forearm pronation and supination, and stabilization of proximal ulnar stump. This study was performed to evaluate the clinical outcomes of modified Sauve-Kapandji procedure for patients with DRUJ dysfunction.

Methods Fourteen patients with DRUJ dysfunction were treated by modified Sauve-Kapandji procedure and followed up for 2 years post-operatively. Functional assessment was evaluated according to modified mayo wrist score (MMWS) system and severity of pain by visual analog scale. Posteroanterior and lateral radiographs were used to assess fusion.

Results There was a significant improvement in VAS of wrist pain (p<0.001) and MMWS (p<0.001) at 2 years follow up. Excellent outcome was reported in 64.3% (n=9) patients. Radiographic fusion was seen in all 14 cases.

Conclusions The modified Sauve-Kapandji procedure for DRUJ dysfunction is a safe and effective procedure with excellent radiological fusion and significant improvement in functional outcomes.
