总结：在固定滑动的股骨头骨骺（SCFE）时，固定针在股骨头中心的位置很重要，原因有二。骨针可能会破坏外侧骺动脉并导致缺血性坏死（AVN），或者骨针穿透某些位置可能无法在X线片上识别。为了准确放置骨针，外科医生必须知道股骨头相对于股骨颈和股骨干的位置。模型和患者在不同位置的X线照片支持这样的观点，即在大多数慢性SCFE病例中，股骨头围绕股骨颈的轴线旋转，并且不会向内侧滑动。因此，原位固定器械的起点是股骨颈前部，确切位置取决于滑动量。
Summary: In pinning a slipped capital femoral epiphysis (SCFE), the position of the pin within the center of the femoral head is important for two reasons. The pin may disrupt the lateral epiphyseal artery and cause avascular necrosis (AVN), or pin penetration in certain locations may go unrecognized on radiographs. To place the pin accurately, the surgeon must be aware of where the femoral head lies in relation to the femoral neck and the shaft. Radiographs of models and of patients in various positions support the view that the femoral head in most cases of chronic SCFE rotates around the axis of the femoral neck and does not slip inferiorly. Therefore, the starting point for an in situ fixation device is the anterior femoral neck, the exact location depending on the amount of slipping.
