In 40 children with unilateral Perthes' disease, we measured the physeal slope, the angle between the physeal plane and the axis of the femoral shaft, from radiographs taken early in the disease. Thirty-seven of the 40 hips were classified as Catterall grades III and IV. Heat-at-risk signs were present in 23. We found no statistically significant difference in the physeal slope between the involved and normal hips (p = 0.20), those with or without head-at-risk signs (p = 0.96), those with or without lateral epiphyseal subluxation (p = 0.82), and different Catterall (p = 0.56) or lateral pillar (p = 0.67) gradings.
在40名单侧佩特兹病患儿中，我们根据疾病早期拍摄的X线片测量了骨骺斜率，即骨骺平面与股骨干轴线之间的夹角。40个髋关节中有37个被归类为卡特拉尔III级和IV级。有23个存在高危体征。我们发现，患侧髋关节与正常髋关节之间、有或无高危体征的髋关节之间、有或无外侧骨骺半脱位的髋关节之间以及不同卡特拉尔分级（p = 0.56）或外侧柱分级（p = 0.67）的髋关节之间，骨骺斜率均无统计学显著差异（p = 0.20），有或无高危体征的髋关节之间（p = 0.96），有或无外侧骨骺半脱位的髋关节之间（p = 0.82）。
