PELVIC SUPPORT OSTEOTOMY WITH ILIZAROV METHOD;

Abstract

Objectives: To determine the outcome of pelvic support osteotomy with Ilizarovmethod in patients undergoing Girdle stone procedure in terms of pain relief and limb lengthdiscrepancy. Study Design: Descriptive case series. Setting: Department of Orthopaedicand Spine Surgery, Ghurki Trust Teaching Hospital/Lahore Medical & Dental College, Lahore.Duration of Study: Six months (19-11-09 to 18-05-10) for sample collection and follow upfor next one year after the procedure. Materials and Methods: Forty five patients having hipjoint problems were included. The radiographs would include plain radiographs of the pelvisin neutral and single limb standing position and the femur of involved side to assess the pelvicobliquity. Surgery was performed in the supine position under spinal anesthesia. A proximalfemoral osteotomy was performed at the level of ischial tuberosity. The other distal femoralosteotomy was performed to lengthen and adjust the mechanical axis. Both these osteotomieswere then stabilized with Ilizarov external fixator. The standard rate of distraction is 1 mm/dayfor lengthening. Results: There were 30 male patients and 15 were female patients with maleto female ratio was 2:1. The mean ± SD between the ages was 23.69±7.80 years. Among allpatients, 43 patients had pain relief and 41 patients of limb length discrepancy. Conclusion:By using the Ilizarov technique, we could prevent the valgus effects created by the valgusextension osteotomy while achieving lengthening of the femur through the distal osteotomy inthe femur. It is an excellent technique for those patients who are not fit for total hip replacement.
