s. Results: We experienced 31 patients of tendon ruptures in rheumatoid hand, which were EPL in 3 cases, EDC II, III in 9 cases, EDC IV, V in 42 cases, EDM in 11 cases and FPL in 1 case. The patients’wrist x-rays were classified into class I(1), class II(19), class III(14), class IV(13), class V(2) according to Larsen grade. The incidence of risk factors in each of three groups was analyzed. Out of 34 cases dorsal dislocation of the distal ulna was noted in 31 cases, scallop sign in 23 cases and tenosynovitis in 25 cases. The statistically significant risk factors for tendon rupture were dorsal dislocation of the distal ulna, scallop sign, persistent tenosynovitis and ditstal radioulnar joint crepitus. Conclusion: The risk factors for the tendon rupture in rheumatoid hand were dorsal dislocation of the distal ulna, scallop sign and tenosynovitis in this study. Prophylatic surgical procedures such as tenosynovectomy, wrist synovectomy and resection of osteophyte could effectively prevent rupture of tendons in patients who have risk factors.
