Abstract:
To investigate the clinical improvement of limping gait in patients with ankylotic hips and limb length discrepancy.Methods:From 1996 to 2005,12 patients with ankylotic hips and limb length discrepancy were treated by distraction osteogenesis with a mono-lateral external fixator and an intramedullary nail.The limb length discrepancy was 6.20-12.50 (median 8.45) cm.Limping gait was classified according to the recommendations of the American Academy of Orthopedic Surgeons/Hip Society and scored according to Harris:no limping scored 11 points,mild limping scored 8 points,moderate limping scored 5 points,while severe limping scored 0 points.Limping gait was severe in all patients pre-operatively and the total score was 0.Results:All patients were followed up for 30.00-46.00 (median 38.55) months,and all reported improvement in limping gait.The gain in length was 6.00-12.50 (median 8.20) cm,and the mean residual limb length discrepancy was 0-0.50 (median 0.20) cm.The total treatment time was 41.00-82.00 (median 61.50) weeks,the lengthening time was 14.00-38.00 (median 29.55) weeks.At the last follow-up,10patients had mild limping gait and 2 had moderate limping gait; the total score was 90.00.The median score was 7.50 (P25 was 8.00,P75 was 8.00).According to Wilcoxon signed rank test,the post-operative limping gait scores were significantly higher than pre-operative (P=0.001 ).Conclusion:Femoral lengthening can improve the limping gait significantly in ankylotic hips and limb length discrepancy.
