摘　　要：目的　为选用吻合血管同种异体骨移植的供区提供解剖学依据。方法　选用经动脉灌注红色乳胶的成人上、下肢标本各 40侧 ,着重对肱骨、桡骨、股骨和胫骨的滋养血管、进行观测 ;另选上述供骨区成人干燥骨各 5 0根 ,作滋养孔 (或称管 )观察。结果　肱骨上端有 4～ 12个滋养孔 ,旋肱前、后动脉是其滋养血管主要来源 ;肱骨干滋养孔多位于肱骨中段前内侧面 ,滋养动脉多发自肱动脉 ;桡骨下端滋养血管主要由骨间前动脉及桡动脉供应 ;股骨干滋养孔 1～ 3个 ,滋养动脉来自股深动脉的穿支 ;胫骨干滋养孔恒定位于胫骨中、上 1/3段后面 ,滋养血管来自胫后动脉分支。结论　根据长骨大段骨缺损 ,选用在外形上与受区相匹配的供骨 ,上述血管长度。Objective To provide anatomic basis for the donor area of vascularized allogeneic bone transplantation. Methods The nutrient vessels of the humerus, radius,femur and tibia were observed on 40 sides of adult cadaveric upper and lower limbs perfused with red latex in artery respectively. Dried nutrient foramen was observed in the above donor site bone of 50 adult dry bones. Results There were 4 to 12 nutrient foramen in the proximal humeral metaphysis.The anterioror posterior circumflex arteries were the main nutrient vessels.The location of nutrient foramen of the humeral diaphysis was mostly in the anterior and medial side of the middle humerus.And the nutrient vessel came from humeral artery.The nutrient vessel of the lower end of radius mainly supplied by anterior interosseous artery.There were l to 3 nutrient foramen in the femoral diaphysis and its nutrient artery originated from the perforating branches of profound femoral artery.Nutrient foramen of the tibial diaphysis constantly located in the posterior of proximal and middle tibia.Its nutrient vessel came from the branches of posterior tibial artery. Conc1usion The donor bone in accordance with the recipient area bone in the appearance should be chosen according to the large segment bone defect of long bone.The length and diameter of above vessels are suitable for the anastomosis of microsurgery.
