Abstract: Objective To explore the number, distribution and outer diameter of retinacular artery branch of pig femoral head and its significance. Methods Thirty-nine isolated pig femoral head specimens with peri-hip vessels were dissected, the retinacular artery were separated, and microperfusion was performed with 30% barium sulfate suspension. The shape, number, distribution and outer diameter of the retinacular artery's entry branch were observed. The distribution of the arterial head was recorded according to the time points. The micrometer was used to measure the external diameter of the retinacular artery branch. The position of the thickest branch of the retinacular artery in each group were measured statistically. Results There were(6.10±1.32) arteries in the pig femoral head, which were mainly divided into three groups: a posterosuperior group, a posteroinferior group and an anterior retinacular artery group. The clock points of the thickest branch head of each group of retinacular artery were (11:22~01:29),(06:36~08:15),(02:01~03:59)o'clock, respectively. The diameters of the three groups were(0.37±0.11),(0.52±0.11),(0.35±0.09)mm, respectively. Conclusions The number and location of the pig femoral head inlet arteries are relatively constant. The average diameter of the thickest branch of the pig femoral head inlet arteries is(0.52±0.11)mm, which origining from the posteroinferior retinacular artery group  and is an important blood supply source for pig femoral head.
