[Reconstruction of metacarpophalangeal and interphalangeal joints with endoprostheses following injuries].

Implants have been used since 1969 by the authors for the replacement of damaged finger joints following trauma. In several cases reconstruction of other damaged tissues in the same finger was also performed. A method is described for replacement of the central slip of the extensor tendon over the PIP joint. Analysis of twenty-one MP and sixty-eight PIP endoprostheses placed in eighty-three patients until 1979 is given. Significant improvement in the range of movement is seen. Preoperative pain was relieved in all cases. There was a need to change occupation in ten percent of patients. Careful analysis of early and late complications calls attention to the proper selection of patients for surgery.
