Yellow line = the thoracolumbar fascia (TLF) as a double line representing the so-called two-layer model described by Willard.3 The posterior layer posterior to the erector spinae muscles and the anterior layer separating the QL muscle and the LG muscle.
Yellow line =胸腰筋膜(TLF)标记为双线,代表Willard所描述的所谓两层模型。
胸腰筋膜后层在竖脊肌后方,胸腰筋膜前层把腰方肌和最长肌分隔开(竖脊肌一部分)。
White line = the peritoneal recess separating the abdominal wall muscles from the PM。
White line = 腹膜隐窝把腹壁肌肉和腰大肌分隔开
L4 = vertebral body of L4 = L4 椎体
LG = longissimus muscle (part of erector spinae muscles)
LG = 最长肌(竖脊肌一部分)
MF = multifidus muscle (part of erector spinae muscles)
