Morphometry of pyramidalis muscle and its role in reconstructive surgeries: A cadaveric study

The following parameters were measured using a vernier calliper. <br> Length of muscle from the pubic symphysis to its attachment to linea alba (apex) along its medial border. Width at the base/origin of the muscle. The thickness of the muscle at the midpoint of the measured length. Distance between the umbilicus and pubic symphysis (DUP) and distance between the umbilicus and apex of the muscle (DUA). Distance between the anterior superior iliac spine (ASIS) and lateral part of the base of the muscle (LBM). Distance between ASIS to tip of the muscle. Distance between ASIS and the pubic symphysis (ASIS-PS). The length and breadth of the gap found between the right and left PM at the base were measured in cadavers where the gap was seen.

本研究采用游标卡尺（vernier calliper）测量了以下参数：沿肌肉内侧缘测量耻骨联合至其在腹白线（linea alba）附着端（尖端，apex）的肌肉长度；肌肉基底/起点处的宽度；所测长度中点处的肌肉厚度；脐与耻骨联合之间的距离（DUP）以及脐与肌肉尖端之间的距离（DUA）；髂前上棘（anterior superior iliac spine，ASIS）与肌肉基底外侧部分（LBM）之间的距离；ASIS至肌肉尖端的距离；ASIS与耻骨联合之间的距离（ASIS-PS）；在可见双侧PM基底间隙的尸体标本中，测量该间隙的长度与宽度。
