The purpose of this study was to determine the length of the semitendinosus muscle belly and its tendon in South Indian population and to study the topography and diameter of its neurovascular pedicles. The study included 46 formalin fixed human cadaveric lower limbs. The length of the semitendinosus muscle belly and its tendon were measured. The neurovascular pedicles of the semitendinosus muscle were identified and counted. The diameter of the neurovascular pedicle was measured just before its entrance into the semitendinosus muscle. The topographical distance of the neurovascular pedicles from the origin of the semitendinosus muscle were determined. The mean length of the semitendinosus muscle belly was 332.3±36.1 mm and its tendon measured 154.8±31.9 mm. The mean diameter of the vascular pedicle was measuring 11.4±9.1 mm, just before its entrance into the semitendinosus muscle. The neurovascular pedicles, of the semitendinosus muscle were ranging between 1 and 7. The distance of the entrance of neurovascular pedicle to the semitendinosus muscle from its origin was ranging between 46 and 272 mm. It was observed that the neurovascular pedicles were highest (31%) at the range of 151-200 mm away from the ischial tuberosity. The morphometric data obtained in the present study is enlightening to the orthopedic and plastic surgeons. The topographical knowledge of the neurovascular pedicles has its implications during the harvesting of the grafts and pedicle flaps. The diameter of vessels in the pedicles is enlightening because of new method of anterior cruciate ligament reconstruction.
本研究的目的是确定南印度人群中半腱肌肌腹及其肌腱的长度，并研究其神经血管蒂的局部解剖结构和直径。该研究纳入了46条用福尔马林固定的人类尸体下肢。测量了半腱肌肌腹及其肌腱的长度。识别并计数了半腱肌的神经血管蒂。在神经血管蒂进入半腱肌之前测量其直径。确定了神经血管蒂距半腱肌起点的局部解剖距离。半腱肌肌腹的平均长度为332.3±36.1毫米，其肌腱长度为154.8±31.9毫米。血管蒂在进入半腱肌之前的平均直径为11.4±9.1毫米。半腱肌的神经血管蒂数量在1至7个之间。神经血管蒂进入半腱肌处距其起点的距离在46至272毫米之间。观察到神经血管蒂在距坐骨结节151 - 200毫米范围内最多（31%）。本研究获得的形态学数据对骨科和整形外科医生有启发作用。神经血管蒂的局部解剖知识在采集移植物和带蒂皮瓣时具有重要意义。由于前交叉韧带重建的新方法，血管蒂中血管的直径也具有启发作用。
