Developing three dimensional visualization of blood supply to the femoral head
摘要
Abstract
Objective To develop three dimensional (3D) visualization of blood supply to the femoral head.Methods Six fresh hip specimens and 28 formalin fixation hip specimens were observed and scanned with CT and micro CT,and the 3D visualization of blood supply to the femoral head was developed with computer software.Results The anatomical observation showed that the range of the blood supply of the ligamentum teres artery varied very much,while few supplied the whole femoral head,additionally some femoral nutrient arteries also supplied the whole femoral head.The blood supply of the femoral head derived primarily from the medial femoral circumflex artery (MFCA) and the lateral femoral circumflex artery (LFCA),however,the largest contributor to that was the superior Weitbrecht's retinacula.The distribution and complex anatomy of the lateral and medial femoral circumflex arteries,arterious circle and the retinacula of Weitbrecht were shown precisely with the 3D visualization.Conclusion The 3D visualization has been developed,and all details of derivation and distribution of blood supply to the femoral head can be reproduced with the developed 3D visualization.关键词
