Summary
A retrospective study of 76 intertrochanteric fractures was undertaken to evaluate the failures of fixation. In every case anatomical reduction was attempted, and 135° sliding compression screws and plates were used for fixation. In 2 cases, the screw penetrated into the joint and there were 8 cases where there was excessive sliding of the implant. These complications were only found in unstable fractures. They occurred most frequently in elderly patients, and when the distal fragment was displaced medially and anteriorly.
Résumé
Une complication majeure du traitement opératoire des fractures intertrochantériennes et particulièrement des fractures instables est l'échec de fixation. Une étude de 76 fractures intertrochantériennes consécutives, traitées du 1er mars 1989 au 28 février 1991, a été réalisée. Toutes les fractures ont été réduites anatomiquement et fixées par une vis à compression de 135°. Il y a eu deux cas de pénétration intra-articulaire de la vis (3,2%) et huit cas de glissement excessif (12,9%). Cette complication n'a été observée que dans les fractures instables et la fréquence du glissement excessif était significativement plus élevée chez les malades âgés et dans les cas où le fragment distal était déplacé en dedans et en avant du fragment proximal. L'instabilité de la fracture, l'âge du malade et le type de déplacement peuvent être considérés comme les causes principales du glissement excessif.
