An unreported condition of the legs in infants was found in more than 130 children referred to one hospital from 1973-1979. One hundred of these children were studied. One leg, usually the right, lay in external rotation. Although there was no loss or restriction of movement at the hip joints, in most cases there was a difference in the arc of rotation. Eleven children also had mild hooking of the forefoot on the unaffected side. Hip radiographs were normal in all cases. Obstetric records were reviewed in 70 cases, but no relation was found between presenting position at birth and side of the affected limb. The condition resolved spontaneously in most of the children who were follow up. This condition may cause anxiety to parents and doctors but it seems to be a variant of normal with an excellent prognosis.
1973年至1979年间，一家医院接诊的130多名儿童中发现了一种未被报道过的婴儿腿部病症。对其中100名儿童进行了研究。一条腿，通常是右腿，呈外旋状态。虽然髋关节没有活动丧失或受限，但在大多数情况下，旋转弧度存在差异。11名儿童在未受影响的一侧还伴有轻度前足内翻。所有病例的髋关节X光片均正常。对70例病例的产科记录进行了复查，但未发现出生时的胎位与患侧肢体之间存在关联。在大多数接受随访的儿童中，这种病症自行缓解。这种病症可能会让家长和医生感到焦虑，但它似乎是正常变异，预后良好。
