AIM: Total hip arthroplasty for severe chronic proximal femoral migration, most commonly seen in congenital dislocation of the hip, has been associated with high rates of complications. Placement of the acetabular component in the true acetabulum has yielded the most durable results, but leads to significant limb lengthening. In this paper six cases of a total hip arthroplasty combined with a Z-shaped osteotomy of the proximal femur are described.
METHOD: All patients presented with a complete congenital dislocation of the hip. In all procedures the acetabular component was placed in the true acetabulum and the proximal femur was shortened according to a preoperative drawing in a Z-shaped manner.
RESULTS: The clinical and radiological results of the patient collective are presented in this study, the mean follow-up period was 60 months. At the last follow-up no nerve palsy, osteotomy pseudarthrosis or dislocation were detected objectively.
CONCLUSION: The performed procedure seems to be a viable technique in the treatment of coxarthritis in high total hip dislocation.
