[Close injury of the tendon at wrist]

Because of the complicated causes and variable clinical signs, closed injury of tendons at wrist is difficult to diagnosis and treat. Twenty-six cases of tendon ruptur were reported. Among them, 11 cases were caused by bone fracture or dislocation, 8 cases were caused by rheumatoid synovitis, 5 cases were caused by synovial tuberculosis, and 2 cases caused by other. The pathogenesis and clinical signs were analyzed. Twenty-three cases were treated by tendon transfer and 3 cases were treated by tendon transplantation. By average follow-up of 16 months (ranged 6 months to 4 years), the results were as follows: the clip strength and both active and positive motion of fingers were restored in 19 caese, 75% of those were restored in 7 cases and 50% of those were restored in 2 cases. It was suggested that diagnosis, treatment and function rehabilitation should be carried out early, and tendon transfer or tendon transplatation were the method on priority.
