A new ultrasound method was used to measure femoral anteversion (torsion) of both hips in children with unilateral Perthes' disease, children with previous irritable hips, and healthy children of a similar age. In children with Perthes' disease, the mean femoral anteversion of affected hips is significantly higher compared with normal controls. In the opposite hips, femoral anteversion for right and left hips separately is not significantly different from that of controls. The affected hips show a significantly greater scatter of anteversion than do normal hips, which could be secondary to the disease; but the opposite hips also show a significantly wider scatter of anteversion than do normal hips, which suggests a developmental abnormality of femoral torsion in the femur of the unaffected limb. In children with Perthes' disease, femoral anteversion asymmetry is characteristic, marked, and significantly different from that of normal hips, with the affected hips usually being the more anteverted (with two exceptions). Irritable hips show significantly greater femoral anteversion asymmetry than do normal hips, with the affected femur usually being less anteverted than the opposite femur. These observations may have relevance in Perthes' disease with respect to both etiology, femoral osteotomy, and prognosis.
一种新的超声方法被用于测量单侧佩特兹病患儿、既往有髋关节一过性滑膜炎的患儿以及年龄相仿的健康儿童双髋的股骨前倾（扭转）情况。在佩特兹病患儿中，患侧髋关节的平均股骨前倾明显高于正常对照组。在对侧髋关节中，左右髋关节各自的股骨前倾与对照组相比无显著差异。患侧髋关节的前倾散度明显大于正常髋关节，这可能是疾病所致；但对侧髋关节的前倾散度也明显宽于正常髋关节，这提示未患病肢体的股骨存在扭转发育异常。在佩特兹病患儿中，股骨前倾不对称具有特征性、较为明显，且与正常髋关节有显著差异，患侧髋关节通常前倾程度更大（有两个例外）。髋关节一过性滑膜炎患儿的股骨前倾不对称明显大于正常髋关节，患侧股骨通常比另一侧股骨前倾程度小。这些观察结果可能在佩特兹病的病因、股骨截骨术及预后方面具有相关性。
