title: [Dorsal tenolysis and arthrolysis of the proximal interphalangeal joint. 19 cases].
abstract: 18 patients suffering from PIP stiffness in extension were treated by dorsal teno-arthrolysis. PIP joint stiffness was due to 3 cases of fracture of P1, 2 cases of fracture of P2, 2 cases of extensor tendons, 8 fractures of P1 associated with section of the extensor tendon, 2 cases of PIP closed trauma (1 sprain, 1 dislocation), and 2 crush injuries of the extensor tendon at the PIP joint. The surgical technique combined a dorsal sinuous approach, tenolysis of the extensor tendon on the dorsum of first phalanx dorsal capsulotomy, and more rarely (3 cases), section of collateral ligaments. The mean pre-operative active flexion was 44 degrees and the mean post operative active flexion was 78 degrees, which represents a gain of 34 degrees of active movement. Thanks to a classification which incorporates the range of active flexion in PIP joint, and the lock of active extension we rated 3 results as excellent, 4 as good, 8 as useful and 4 as insufficient. We therefore improved the range of movement in 15 out of 19 cases, which seams very encouraging.
