Abstract:
Objective To observe the long- term result of pathological dislocation of the hip with absence of the femoral head treated with trochanteric arthroplasty in infancy. Methods Eighteen cases with absence of the femoral head and pathological dislocation of the hip treated with trochanteric arthroplasty were followed- up for 5－ 16 years, with an average of 9.25 years. The timing of the surgery was average 18.2 months(ranged from 11 to 30 months). Based on Hunka pathological classification, one case was divided as typeⅠ lesion, 2 cases as typeⅡ lesion and 15 cases as typeⅤ lesion. Results There were 8 cases in the excellent group, the morphology and function of the reconstructed femoral heads were nearly normal and the limb shortening were in an average of 0.25 cm. There were 3 cases in good group, the femoral heads were nearly ball sized and the femoral necks were absent, however, the function was good and the limb shortening averaged 1.5 cm. There were 5 cases in fair group, the plastic femoral heads were abnormal and there were acetabular dysplasia and the limb shortening averaged 2.1 cm. There were 2 cases in poor group with redislocation. Conclusion The result demonstrate that surgical treatment of the absence of the femoral head in infancy could obtain a better reconstructed hip and fair function; the shortening of the limb can also be avoided.
