摘　　要：Perthes病是一种原因不明的儿童特发性股骨头坏死,常发生于2~14岁男性患儿。大多数预后良好,但仍有部分患儿成年后可残留股骨头畸形而致患侧髋关节过早发生骨关节炎。因此,临床医生亟需早期评估患儿预后以采取有效治疗方法避免不良结局。本文回顾和总结了X线平片和磁共振成像检查对Perthes病预后评价的价值,为临床早期评价疾病预后提供影像学依据。With an unknown etiology,Legg-Calvé-Perthes disease is a kind of idiopathic femoral head necrosis of children.It occurs frequently in boys aged 2-14 years.Clinical outcomes are generally decent.However,some children with Perthes disease have residual femoral head deformity leading to early osteoarthritis of the hip during growing up.Clinicians should evaluate patients comprehensively and intervene promptly and properly to avoid poor outcomes.This review summarizes the prognostic values of Legg-Calvé-Perthes disease using radiology and magnetic resonance imaging(MRI),aiming to offer imaging rationales for an early prognostic evaluation.
