It has already been shown in animals and using anatomical human specimens that chronic slippage of the adolescent upper (capital) femoral epiphysis is unlikely to take place by shearing due to the presence of an epiphyseal tubercle projecting down into the metaphysis.
MATERIAL, RESULTS, AND INTERPRETATION: Plain radiographs of 20 adolescents and CT scans of 9 of them were analyzed for evidence of the size and presence of this tubercle in vivo. These cases showed that CT scanography is the investigation of choice to illustrate this largely undescribed anatomical feature. They also illustrate the epiphyseal tubercle well, both in the anatomical position and at various stages of "epiphyseal slippage", and confirm that it has a significant restraining effect on any tendency of the epiphysis to alter its position relative to the metaphysis.
已经在动物和使用解剖人体标本中表明，青少年股骨上端（骨骺）的慢性滑离不太可能由于骨骺下突入干骺端的骺结节而发生剪切。
材料、结果和解释：分析了 20 名青少年的普通 X 光片和其中 9 名的 CT 扫描，以寻找该结节在体内的大小和存在的证据。这些病例表明，CT 扫描是说明这种基本未描述的解剖特征的首选检查方法。它们还很好地展示了骺结节，无论是在解剖位置还是在“骨骺滑离”的各个阶段，并且证实它对骨骺相对于干骺端改变位置的任何趋势都有显著的抑制作用。
