Electrical stimulation of the nerve to the gracilis muscle following its transposition around the anal canal creates an artificial sphincter capable of actively opposing intrarectal pressure. Not all patients have an available or suitable gracilis. This paper describes the anatomic basis for the use of the long head of the biceps femoris as a potential electrically stimulated neoanal sphincter. The muscle was found to have an adequate length and a suitable arc of rotation for transposition around the anal canal. In 75 percent of thighs studied the neurovascular anatomy of the long head of the biceps femoris was compatible with its utilization in this manner as an alternative to the gracilis.
将股薄肌围绕肛管转位后对其神经进行电刺激，可形成一个能够有效对抗直肠内压力的人工括约肌。并非所有患者都有可用的或合适的股薄肌。本文描述了使用股二头肌长头作为潜在的电刺激新肛门括约肌的解剖学基础。发现该肌肉具有足够的长度和合适的旋转弧度，可围绕肛管转位。在研究的75%的大腿中，股二头肌长头的神经血管解剖结构适合以这种方式替代股薄肌使用。
