Twenty-one adult subjects who had symptomatic residua of unilateral congenital dysplasia of the hip, with various degrees of degenerative changes, were studied with respect to the physical and radiographic findings and gait performance. Three-dimensional body reconstruction; the Trendelenburg sign; spatiotemporal parameters of stride; ground-reaction forces; kinematics of the hip, knee, and ankle; moments of forces; and joint powers were evaluated bilaterally. The kinematic and kinetic parameters of the affected limb were compared with those of the unaffected limb and with those of the limbs of normal control subjects. Correlations between changes in selected gait parameters and the clinical and radiographic signs of impairment of the hip were demonstrated. The results are discussed in relation to the possible mechanisms underlying the observed alterations and in view of possible operative interventions.
对21名患有单侧先天性髋关节发育不良症状性残留且伴有不同程度退行性改变的成年受试者，就其体格检查、影像学表现及步态表现进行了研究。双侧评估了三维身体重建、单足站立试验；步幅的时空参数；地面反作用力；髋、膝和踝关节的运动学；力的力矩；以及关节功率。将患侧肢体的运动学和动力学参数与未患侧肢体以及正常对照受试者的肢体参数进行了比较。证实了所选步态参数变化与髋关节损伤的临床及影像学征象之间的相关性。结合观察到的改变可能的潜在机制以及可能的手术干预措施对结果进行了讨论。
