文题释义:
蛙位片:患者仰卧于摄影台上,身体正中对向暗盒中线,双髋及双膝各屈曲90°并外旋45°,以腹股沟中点为透视中心点。
蛙位分型:根据股骨头应力和坏死分布特征,作者认为股骨头前外侧部在股骨头坏死预后和保髋治疗中具有重要的地位和作用。正位分型可以较好反映股骨头顶、外侧负重区的坏死范围和塌陷程度,但由于体位遮挡,对股骨头前外侧负重区变化不能分辨。在此背景下,庞智晖等创立了蛙位分型,以更好地反映股骨头前外侧部的坏死范围和塌陷程度,减少观察盲区,提高观察的准确度。蛙位分型标准与正位分型一致,以股骨头标准蛙位X射线片为分型依据。
广中医生物力学实验室分型:以髋关节眉弓线以及股骨头坏死范围为参考,正蛙位分型中A型(坏死范围占据髋臼眉弓线小于或等于内侧1/3)、B型(坏死范围占据髋臼眉弓线小于或等于内侧2/3)、C型(坏死范围占据髋臼眉弓线超过2/3),其中C1(坏死范围未超越髋臼外缘)、C2(坏死范围超越髋臼外缘)。结合正蛙位分型,进一步分为“包容型(正蛙位分型均未超过C1)、开放型(正蛙位分型均达C2)、过渡型[正蛙位分型之中一个达到C2,另一个在C1以下(含C1)]”。
 
摘要
背景:股骨头坏死病灶的三维信息对制定治疗方案极为重要,而过往的生物力学研究更表明股骨头前外侧柱部分几何信息和受力情况左右其塌陷过程。目前使用的平片方法无法呈现相关信息,对治疗方案的制定存在一定的观察盲区。
目的:利用双平片方法呈现立体的坏死部位和范围,改良股骨头的三维分区,制订新分型标准,以提高分型对制定治疗方案的指导意义。
方法:根据日常活动中股骨头应力传递方式的数据研究,结合股骨头坏死发病塌陷过程中的应力异常边界及临界值等资料,将股骨头划分为五柱,创立立体五柱分区。并根据正位和蛙位摄片体位下的前外侧柱影像信息,进一步优化立体五柱分区法,成为股骨头前外侧柱分型法,并命名为广中医生物力学实验室分型。

结果与结论:详细描述广中医生物力学实验室分型的分型原理、方法和标准,以案例演示操作的方法,并比较传统分型方法,凸显新分型的优点,不但能简便准确判断股骨头坏死的病情及预后,更能有效指导临床治疗方案的选择。

Abstract:

BACKGROUND: Three-dimensional information of osteonecrosis of the femoral head is critical for the treatment planning. The geometry and loading condition of the anterolateral of the femoral head can influence the progression of collapse. However, current assessment using radiography cannot reveal the relevant information and thus may hinder understanding for accurate treatment planning.
OBJECTIVE: To visualize the three-dimensional necrotic site and area based on a biplanar X-ray, to advance the three-dimensional division of femoral head and make new classification method, so as to guide clinical practice.
METHODS: We established a three-dimensional five-column classification system for osteonecrosis of the femoral head according to the load/stress transfer profile of the femoral head during daily activities, and the abnormal stress boundaries and threshold values during the onset and collapse progression of osteonecrosis of the femoral head. The classification system is further optimized as “anterolateral column classification system” by the geometry information of the anterolateral columns acquired from the frog-leg lateral and frontal images. The classification is named as the “Biomechanics Laboratory of Guangzhou University of Chinese Medicine Classification system”.
RESULTS AND CONCLUSION: This study describes the classification principle, method and standard of “Biomechanics Laboratory of Guangzhou University of Chinese Medicine Classification system” in detail. Through a case study, the advantages of the new system are highlighted. The new system can easily and accurately assess the condition and prognosis of osteonecrosis of the femoral head that provides effective guidelines for treatment planning.
