Material and methods

We compared 2 groups of patients: Group I-93 patients with total hip arthroplasty after intertrochanteric osteotomy and Group II-93 patients with primary total hip arthroplasty. The patients in the control group (Group II) were randomly chosen from the cases operated by the same surgical team using the same kind of implant like those in Group I. The osteotomies were of different types: medial displacement (27), varisation(19), valgisation (18), flexion(25), rotational (4). The demographic parameters were similar in the 2 groups. Technical intraoperative challenges were noted. The Harris Score was determined at 12 months and 3 years after surgery. Clinical and radiological check-ups were performed each year. The duration of each surgical procedure was recorded. Complications were noted during the entire follow-up. The mean follow-up was 77 months.
