title: Analysis of twenty-eight recurrent pseudarthroses of the carpal navicular after the Matti-Russe operation.
abstract: The authors present a review of 28 cases of failure of consolidation of the carpal navicular after the Matti-Russe operation (multicentric study of 106 cases). The causes of the failures are analysed. Among the non significant factors, we find the delay, the radiographic character of the pseudarthrosis, the donor site of the graft, the time of immobilization and the site of the fracture. The superior polar fractures do not have a bad prognosis in this series. Five causes seem to be in direct relation with the failure of consolidation: the age, the failure of an initial surgery procedure, the presence of radiologic "necrosis", the quality of the technical performance of the Matti-Russe operation, and finally dorsal carpal instability that seems to be a fundamental cause in the failure of bony union. The future of these pseudarthroses is analysed concerning: the functional results (64% of poor results); the evolution towards the pseudarthrosis (30%); the surgical reoperations (12 cases out of 28) with eight repeat Matti-Russe operations that finished in five consolidations.
