Eighty patients who had unilateral coxa plana and who had been treated conservatively were followed to a mean age of sixteen and one-quarter years, and their cases were reviewed for radiographic evidence of a disturbance of the femoral capital growth plate. This physeal involvement was inferred by the presence of one or more of five findings: premature physeal closure, overgrowth of the greater trochanter, change in physeal shape, lateral protrusion of the capital nucleus, and medial bowing of the femoral neck. Premature physeal closure, which was more common in the girls than in the boys, occurred in 25 per cent of the affected femoral heads, and 90 per cent of the patients showed some interference with normal physeal growth in the affected femoral head. A direct correlation was found between the severity of the physeal involvement and the ultimate deformity of the femoral head. The possible causes of interference with physeal growth and damage are discussed.
对80例单侧扁平髋且接受保守治疗的患者进行随访，直至平均年龄达到16岁零3个月，并复查其病例，以寻找股骨近端生长板紊乱的影像学证据。通过以下五项发现中的一项或多项来推断生长板受累情况：生长板过早闭合、大转子过度生长、生长板形状改变、股骨头骨骺外侧突出以及股骨颈内侧弓形弯曲。生长板过早闭合在女孩中比男孩中更常见，发生在25%的受累股骨头中，90%的患者显示受累股骨头的正常生长板受到某种干扰。发现生长板受累的严重程度与股骨头最终畸形之间存在直接关联。文中讨论了干扰生长板生长和造成损伤的可能原因。
