[Tenosynovectomy of the flexors in rheumatoid polyarthritis. Analytic study of short term and long term mobility of the fingers].
Between 1970 and 1988, 115 patients with rheumatoid arthritis underwent flexor tenosynovectomy. Fifty patients were reviewed (64 hands). The diagnosis of flexor tenosynovitis remains a clinical diagnosis. Three main groups can be distinguished: isolated carpal tenosynovitis (20%), palmodigital tenosynovitis (50%), diffuse tenosynovitis (30%). Standard surgical techniques were used, particularly in terms of the incisions. All patients underwent rehabilitation in the same rehabilitation centre. The authors analyse their results by comparing overall preoperative and postoperative mobility of the fingers (TAM: Total Active Motion, TPM: Total Passive Motion) and the angular gain in each joint (MCP, PIP, DIP). They report the results obtained at 4 months to eliminate the bias related to progression of the disease. The long-term results (8 years of follow-up) are also analysed. Statistical analysis compares two groups depending on whether flexor tenosynovectomy was isolated (44%) or combined with a dorsal surgical procedure at the same operation (extensor synovectomy, articular synovectomy, stabilisation-realignment of the dorsal aspect of the wrist, resection of the ulnar head) (56%). Ninety percent of patients declared themselves to be subjectively improved. Objectively, mobility was always improved at 4 months then deteriorated to return to its preoperative level at 8 years. Only three patients were reoperated for recurrence. Flexor tenosynovectomy in rheumatoid arthritis is an excellent operation. Its analgesic effect is maintained in time and, when performed early, it appears to protect the patient from the risk of subsequent tendon rupture.
