[Extensor tendon rupture after dorsal surgery of the rheumatoid wrist: analysis of nine reviewed cases].
We led a retrospective study to determine the causes of the tendon ruptures post-operating in the surgery of the wrist rheumatoid dorsal and to estimate the clinical result. At follow-up, we measured the extension lag and the rolling-up of fingers by the distance palm-pulps. Nine patients were so revised in the average of 40 months, average age was of 50.7 years. The tendon ruptures arose in 3 months in 67% of the cases. Seven times, a procedure on the distal radio-ulnar joint had been necessary (5 Sauvé-Kapandji and 2 Darrach). Thirty tendons had been concerned in this study, that is 3.3 tendons on average (1-5). Two main causes were found: attrition on the stub ulnaire and great intra-tendinous synovitis (per operating observation). At the revision, the lag extension means was 23 degrees (0-40). Rolling-up of the long fingers was complete 4 times on 7. The best results were observed after tendinous grafting or index proprius transfer with a lateral suture. Tendinous adhesions had arisen 6 times and persisted still at 3 patients. Our study underlines the interest to stabilize the stub ulnaire to prevent the post-operating ruptures and proposes a transfer or a graft in front of tendons very weakened by the synovitis.
