胫骨血液供应的实验和解剖学研究

本文对45侧下肢标本和15只狗进行了胫骨血供的实验和解剖学研究。胫骨血供是以滋养动脉为主干,并与骺血管和骨膜血管存在广泛吻合。切除狗胫骨大面积骨干骨外膜并同时切断滋养动脉后,创面渗血仍然存在,经2—20周观察未见出现骨质的缺血性坏死,表明胫骨各个供血系统相互间代尝作用很强。

Experimental study on the blood supply of the tibia

The blood supply of the tibia was studied on 45 lower limbs of adult human cadavers and 15 posterior limbs of adults dogs. The blood supply of the tibia was mainly from the nutrient artery, and from the network of vessels ramifying in the periosteum and epiphysis. These vessels anastomosed with each other. After most part of the periosteum of the tibial shaft of the dogs was excised and the nutrient artery was severed, the blood oozing out from the bone surface could still be observed, however, no ischemic necrosis in the bone shaft was observed throughout the 2-20 weeks of observation.The results showed that there was sufficient compensatory action among the various groups of blood vessels.
