带血供半腱肌肌腱重建前交叉韧带的应用解剖

Applied Anatomy of the Semitendinous Tendon with Blood Supply to Reconstitute Anterior Cruciate Ligament

目的:为带血供半腱肌肌腱重建前交叉韧带提供应用解剖学基础。方法:在50侧成人下肢标本上观测半腱肌肌腱形态、血供来源、分支及分布特点;在2侧新鲜下肢标本上进行模拟手术。结果:半腱肌肌腱长(15.1±0.3)cm,宽(0.5±0.1)cm,厚(0.4±0.1)cm,其血供主要来源于动脉的半腱肌支、膝下内侧动脉的腱支、腱外周组织血管网动脉和胫前返动脉。结论:半腱肌肌腱与交叉韧带形态相似,血供丰富,有足够的游离长度。采用带血供的半腱肌肌腱重建前交叉韧带具有可行性。

Objective：To provide anatomy data for tendon of semitendinous muscle with blood supply to reconstitute anterior cruciate ligament. Methods： The shape, blood supply origin, branches and distribution of semitendinous muscle tendon were observed on 50 specimens of adults＇ lower limbs. Sham operations were carried out on two fresh lower limbs. Results： The length of semitendinous muscle tendon was （ 15.1 ＋ 0.3 ） cm, width of （0.5 ＋ 0.1 ） cm, and thickness of （0.4 ＋ 0.1 ） cm. Its blood supply mainly came from the semitendinous muscle branch of arteria poplitea, tendon branch of arteria genus inferior medialis,arteria of vascular net around the tendon,and the arteriae recurrens tibialis anterior.Condusions：The tendon of semitendinous muscle is plesiomorphism to cruciate ligament and has adequate free length, with abundant blood supply.So it is feasibility to reconstitute anterior erueiate ligament by semitendinosus tendon with blood supply.
