Transversus abdominis release (TAR) is a myofascial release technique which helps in surgical repair of largeventral abdominal wall defects. In this procedure, the medial margin of muscular part of transversus abdominis (TA) is ofgreat importance. Hence, the authors sought to describe the extent of medial margin of TA muscle. The surgical steps of TARwere performed in 10 formalin-fixed cadavers and distance between medial margin of TA muscle, lateral margin of rectusabdominis, to linea alba at five anatomical levels were documented respectively. The distance between the inferior epigastricvessels and the medial border of TA muscle was also noted. The TA muscle was within the posterior rectus sheath in allcadavers, at the xiphisternum (R, 61.6 mm; L, 58.9 mm), and at midway between xiphisternum and umbilicus (R, 25.4 mm; L,27.1 mm). The TA muscle exited the posterior rectus sheath between this point and the umbilicus. The mean incongruity atthe next three levels were -24.6 mm, -24.9 mm, and -22.9 mm respectively on the right and -21.4 mm, -19.9 mm, and -18.9mm respectively on the left. The mean distance between the medial border of TA and inferior epigastric vessels was 18.9 mmon the right and 17.2 mm on the left. The muscular part of TA was incorporated within the posterior rectus sheath above theumbilicus, and it completely exited the rectus sheath at the umbilicus. This is contrary to the traditional understanding ofposterior rectus sheath formation.
