[Sauvé-Kapandji procedure in distal radioulnar joint disorders]

Abstract

Objective: To evaluate the functional and subjective results of the Sauvé-Kapandji procedure as a treatment for distal radioulnar joint disorders.

Material and method: A retrospective study was conducted on 27 patients treated using the Sauvé-Kapandji technique from January 2001 to March 2012. The aetiología, age, sex, laterality, articular movement, radiographical signs of joint degeneration, and cubitus varus, were analysed. The Mayo Clinic wrist assessment scale and the DASH questionnaire were used for the postoperative evaluation. The mean follow-up was 24 months (6-48 months). The mean age was 47.2 years, with 66.7% females, and 55% the dominant side.

Results: At one year after surgery, 16 cases had mild or no pain (59.2%), 8 cases with moderate (29.6%) and 3 cases with severe pain (11.1%). The pronation-supination went from a pre-operative average of 96.8° to 136.4° postoperative, operatorios, which was a significant statistical difference (Wilcoxon test). The radioulnar ratio went from an pre-operative average of +2.6mm to -0.39 mm postoperative. Full functional recovery was observed in 48%. A grip strength of 50.6%, compared to the contralateral wrist was achieved.

Conclusions: The Sauvé-Kapandji technique could avoid the complications common in other procedures, such as cubital-carpal migration. Our study agrees with that in the literature with good results as regards the range of joint movement, with an acceptable improvement in pain compared to the previous stage, but it also demonstrates the frequent loss of grip strength and instability of the proximal radio-ulnar joint.
