[Controlled mobilisation after suture of extensor tendons of the hand. Apropos of 30 consecutive cases].

From January 1988 to May 1991, 30 patients (mean age: 27 years old; range: 15 to 45) sustained 57 tendon injuries in 49 fingers. They were treated by primary repair with assisted post-operative mobilisation by a dynamic splint. Adhesion of extensor apparatus rate was 12 p. cent but only one had a functional impairment. No other complications were noted. At the thumb level (3 out of 49 fingers) the Kapandji-test was respectively at 8.8 and 9/10 without any extensor lack. At the long fingers level TAM was excellent in 91 p. cent of cases, good in 4 p. cent, fair and poor in 2 p. cent. According to Allieu classification results were good and excellent in 9 p. cent of cases. These results were better when injury was localised to or up to zone 5 according to Verdan's classification, and when there was no associated bone nor articular injuries or cutaneous defects. Subjective results were less good (70 p. cent of satisfactory results) because of pain, grip strength lack or disability. Assisted mobilisation allowed intrinsic healing and avoided adhesion when application date and rehabilitation protocol were respected. It was more beneficial for distal and complex injuries.
