The purpose of this study was to investigate post-therapeutic lower extremity rotational profiles in children with developmental dislocation of the hip (DDH), the differences between these values and those of normal children, and the relationship between these differences and clinical and radiological results.
In 82 lower extremities of 64 patients, the foot-progression angle was measured clinically and the transmalleolar axis angle photographically, and hip rotations and thigh-foot angle were measured both clinically and photographically. The data obtained were compared with Staheli's data for normal children. In addition, clinical and radiographic data were compared within subgroups and with Staheli's data. Student's t-test and one-way ANOVA were used for statistical evaluation.
The medial rotation of the hip, the average clinical value was 44.66 masculine, and the photographic value was 42.28 masculine. Lateral rotation of the hip, the average clinical value was 38.01 masculine, and the average photographic value was 37.29 masculine. Thigh-foot angle, his angle was clinically 8.23 masculine and photographically 9.68 masculine. Angle of the transmalleolar axis, the photographic average was 21.59 masculine. Foot-progression angle, the clinical average was 10.70 masculine. It was determined that the lower extremity rotational profiles of children with DDH treated after walking did not differ from those of normal children, but that the internal and external hip rotations of McKay type III and IV patients were below those of normal children and of McKay type I and II patients.
Lower extremity rotational profiles in children with DDH who received appropriate treatment were the same as those for normal children.
本研究旨在调查发育性髋关节脱位（DDH）患儿治疗后的下肢旋转情况，比较这些数值与正常儿童的差异，以及这些差异与临床和影像学结果之间的关系。
对64例患者的82条下肢进行研究，临床测量足进展角，通过摄影测量经内踝轴角，同时临床和摄影测量髋关节旋转及大腿-足角。将所得数据与Staheli关于正常儿童的数据进行比较。此外，在亚组内比较临床和影像学数据，并与Staheli的数据进行比较。采用学生t检验和单因素方差分析进行统计学评估。
髋关节内旋，临床平均数值为44.66°，摄影测量值为42.28°。髋关节外旋，临床平均数值为38.01°，摄影平均数值为37.29°。大腿-足角，临床测量为8.23°，摄影测量为9.68°。经内踝轴角，摄影测量平均值为21.59°。足进展角，临床平均值为10.70°。结果显示，步行后接受治疗的DDH患儿下肢旋转情况与正常儿童无差异，但McKay III型和IV型患者的髋关节内旋和外旋低于正常儿童以及McKay I型和II型患者。
接受适当治疗的DDH患儿下肢旋转情况与正常儿童相同。
