RESUMO
BACKGROUND: Hips can suffer severe damage due to untreated developmental dysplasia, septic arthritis, tuberculosis, a neglected fracture of the neck of femur and neglected hip dislocation. The Ilizarov technique offers an effective treatment by providing a stable hip with abolished Trendelenburg lurch and equalizing limb length discrepancy through distal lengthening realignment osteotomy. MATERIAL AND METHODS: 20 patients with hip instabilities due to various etiologies were treated with the Ilizarov technique of pelvic support osteotomy and distal lengthening realignment osteotomy. There were 12 females and 8 males in the study group and the age range was 13 to 30 years. Average limb length discrepancy was 5.95 cms (range 4-8.5 cms).The pre-operative and post-operative range of motion and Harris hip score was collected and data analyzed by Student's paired t test. A p value of < 0.05 was taken to be statistically significant Results. The functional Harris hip score improved in all the patients at final follow-up. The mean Harris hip score was 56.95 (range 33-71) pre-operatively, which improved to 83.25 (range 73-85) at final follow up and was statistically significant (P-value < 0.05). The mean length achieved was 5.53 cms (4-8 cms). The mean external fixation time was 8.6 months and the mean healing index was 1.54 months /cm. CONCLUSIONS: 1. Ilizarov hip reconstruction is an excellent method of salvage in patients with unstable hips diverse etiologies especially in this part of the world, where patients demand unrestricted range of motion at hip, and in the younger age group, where other procedures do not offer a long term solution. 2. It provides an excellent functional outcome in hips of different etiologies. 3. However, for an excellent outcome, surgical expertise, patient compliance and meticulous follow-up are mandatory.
