评价Legg-Calvé-Perthes（LCP）病软骨异常的磁共振（MR）成像表现及其与生长停滞的关系。材料和方法回顾了23例患者25个髋关节的27张MRI图像和X线片，检查骨骺、骨骺和干骺端异常。随访X线片（平均时间20.5个月）评价生长停滞。74%的病例中观察到的骨骺异常与生长障碍无关。在63%的股骨中发现了MRI图像上的经骺骨桥，这是异常生长的最强预测因子（P <0.01）。MR成像有助于发现骨骺异常，其敏感性（94%）、特异性（89%）和阳性预测值（94%）均高于X线摄影。81%的病例中骺板软骨的干骺端延伸与生长异常相关（P <0.01），特别是在X线检查中发现时。
PURPOSETo evaluate the magnetic resonance (MR) imaging appearance of cartilaginous abnormalities in Legg-Calvé-Perthes (LCP) disease and their association with growth arrest.MATERIALS AND METHODSTwenty-seven MR images and radiographs of 25 hips in 23 patients were reviewed for epiphyseal, physeal, and metaphyseal abnormalities. Follow-up radiographs (mean time, 20.5 months) were evaluated for growth arrest.RESULTSEpiphyseal abnormality seen in 74% of cases was not related to growth disturbances. Transphyseal bone bridging on MR images, the strongest predictor of abnormal growth (P < .01), was found in 63% of femurs. MR imaging helped detect physeal abnormalities with greater sensitivity (94%), specificity (89%), and positive predictive value (94%) than radiography. Metaphyseal extension of physeal cartilage seen in 81% of cases was associated with growth abnormality (P < .01), particularly when detected at radiography.CONCLUSIONCartilaginous physeal and metaphyseal abnormalities in LCP disease are common and frequently result in growth arrest.
