[Arthrolysis of the metacarpophalangeal joints in post-traumatic stiffness of fingers in extension].

In cases of post-traumatic stiffness of the metacarpo-phalangeal joints in extension, it is possible to safely perform an arthrolysis with or without tenolysis while preserving the continuity of the extensor mechanism. This paper describes the surgical approach and technique of arthrolysis of the metacarpo-phalangeal joints. Proper operative management of post-traumatic stiffness of the long fingers in extension can improve the results in these cases.
