[Results of screw fixation of the scaphoid pseudarthrosis].

MATTI-RUSSE's cancellous graft is successful in the management of scaphoid pseudarthrosis. The necessity of post-operative immobilization of the wrist, usually previously immobilized, for up to 16 weeks is its disadvantage. Screw fixation including radial styloidectomy and a small cancellous graft is an alternative abbreviating immobilization to only 2 to 6 weeks. the follow-up of 26 patients thus operated revealed osseous union in 19 cases. The failures were due to lack of proper indication or faulty technique. In spite of the correct position of the scaphoid screw one pseudarthrosis did not heal, the clinical result being satisfactory. The procedure described permits early remobilization of the wrist. Failures, also described by other authors, can be avoided by proper indication and technique.
