Keywords: metal fixer, hip joint, endoprosthetics, acetabulum, femur
Abstarct: The removal of metal fixer from the hip joint area requires separate preoperative planning. Objective – to determine the tactics of hip replacement (HR) in the presence of an acetabulum or a femoral metal fixer depending on the degree of severity of consolidation and stability of fixation. Material and methods. The study was performed in the Department of Traumatology and Orthopedics of Moscow Regional Clinical Research Institute named after M.F.Vladimirsky. All cases of unilateral total hip joint replacement in 60 patients (37 men and 23 women) with simultaneous removal of metal fixers were analyzed. Results and discussion. Fusion of the acetabulum was noted in 18 observations, nonunion of the acetabulun – in 6 cases, that of the proximal femur – in 11 patients, nonunion – in 25. 36 operations with total removal of metal fixer were performed, in 9 cases – from the acetabulum, in 27 – from the femur. The results of endoprosthetics with partial or total removal of stable undisturbed metal fixers from the acetabulum were followed in 25 patients. The average score after 2,5 years after endoprosthetics on the Harris scale in this group was amounting to 92 points. Conclusion. The tactics of hip replacement in the presence of metal fixer of the acetabulun or the femur depended on the degree of severity of consolidation and stability of fixation.
