Micro perfusion and quantitative analysis of the in vitro femoral head intraosseous artery
Objective To investigate the feasibility of pig femoral head micro perfusion and quantitative analysis of the intraosseous artery. Methods 12 pig femoral head specimens were perfused using contrast agent of gelatin barium sulfate suspension under surgical microscope. After micro CT scanning,the intraosseous artery three-dimensional digital model was reconstructed. Results Micro perfusion and quantitative analysis of the pig in vitro femoral head intraosseous artery is possible. The reconstructed model is accurate, high resolution， which also contains artery structure, bone mass, and bone structure. Conclusion Micro perfusion of femoral head and quantitative analysis of the in vitro pig femoral head intraosseous artery provide a research technique to study the intraosseous artery morphology for study of femoral head avascular necrosis.
