目前国内外主要的解剖学专著、骨科学专著以及相关的教科书中, 关于股骨头颈部血供分布的描述, 或为示意图, 或为二维图, 均没有提供有关股骨头颈部骨内和骨外血供分布的三维全景图像。这一方面不利于初学者对该部位血供的学习理解, 另一方面也影响临床医师对股骨颈骨折后股骨头血供受损情况的判断及其治疗方法的选择。应用当今先进的影像学技术和计算机图像处理技术, 可建立精准的股骨头颈部骨内和骨外血供分布的三维全景图像。有利于探讨不同股骨颈骨折对股骨头血供可能造成的影响, 设计对不同类型股骨颈骨折的个体化治疗方案。
In terms of distribution of blood supply to the femoral head and neck (FHN),schematic diagrams or planar graphs are expressed in all classical works and textbooks of anatomy and orthopedics.An exact presentation of intra-and extraosseous blood supply to FHN can not be provided which leads to poor understanding of 3D vasculature.On one hand,it is of disadvantage for new learners to know the real circulation to FNN; on the other hand,it makes against reasonable judgment of the severity of local vessels and logical treatment of femoral neck fractures for orthopedic surgeons.To achieve the accurate 3D vasculature networks of FHN through contemporary techniques of radiography and computer image processing.The computer-aided technique of virtual reality is employed for clinical cases of various femoral neck fractures,and further combined with radiographic and histopathological methods to focus on the damaging effect of various femoral neck fractures on the blood supply to the femoral head,and designing individual and optimal treatment protocols for different femoral neck fractures.
