Curved intertrochanteric varus osteotomy for osteonecrosis of the femoral head.
We reviewed the outcome of curved intertrochanteric varus osteotomy in the treatment of osteonecrosis of the femoral head in 20 hips. A mean varus angulation of 31 degrees was obtained by the osteotomy. The ratio of intact area on the weight-bearing portion increased from 19% to 61%. The mean elevation and lateral displacement of the greater trochanter were 1.2 cm and 0.5 cm, respectively. Thes...
متن کاملLeg-length discrepancy after transtrochanteric curved varus osteotomy for osteonecrosis of the femoral head.
Transtrochanteric curved varus osteotomy was designed to avoid some of the disadvantages of varus wedge osteotomy, such as post-operative leg-length discrepancy. In this retrospective study we investigated the leg-length discrepancy and clinical outcome after transtrochanteric curved varus osteotomy undertaken in patients with osteonecrosis of the femoral head. Between January 1993 and March 20...
متن کاملOsteonecrosis of the femoral head. Simple varus intertrochanteric osteotomy.
We present the long-term results of simple varus intertrochanteric osteotomy for osteonecrosis of the femoral head. We followed 26 hips in 20 patients, with a mean age at the time of surgery of 36 years, for a mean of 12.5 years. The mean varus angulation was 23 degrees. The outcome in 19 of the hips (73%) was good or excellent; seven (27%) had a fair or poor result, with four needing some form...
متن کاملTotal hip arthroplasty after failed curved intertrochanteric varus osteotomy for avascular necrosis of the femoral head
Curved intertrochanteric varus osteotomy (CVO) is one of the good surgical procedures for avascular necrosis of the femoral head (ANFH) patients. However, some patients with failed CVO are converted to total hip arthroplasty (THA) as a salvage operation. We compared the clinical and radiographic outcomes of 10 hips converted to THA after failed CVO (Group O) (mean age 43.0 years, 8 male and 2 f...
متن کاملComparison of Surgical Parameters and Results between Curved Varus Osteotomy and Rotational Osteotomy for Osteonecrosis of the Femoral Head
BACKGROUND Various osteotomies have been introduced to treat osteonecrosis of the femoral head. The purpose of this study was to compare surgical parameters, postoperative limb length discrepancy, and minimum 5-year clinical and radiological results between transtrochanteric curved varus osteotomy (TCVO) and transtrochanteric rotational osteotomy (TRO) for osteonecrosis of the femoral head. M...
