在常规尸检中，对年轻黑人和白色男性的腰大肌（PMA）进行了解剖学研究。法医尸体解剖包括44具新鲜男性尸体（21具黑人，23具白色），年龄14 ~ 25岁。体重范围为66-76公斤，身高范围为169-182厘米。在测量每个节段水平（L1-S1）的直径和周长之前，首先测量PMA的整个长度。在每个节段水平，黑人组的计算解剖横截面积（阿克萨）比白色组大3倍以上（P < 0.001）。91%的黑人受试者没有腰小肌（PMI），而白色受试者只有13%。这些数据表明黑人受试者的PMA明显大于白色受试者。PMA尺寸的明显种族特异性差异可能对髋屈肌强度、脊柱功能和下背部病理学的种族特异性发生率有影响，需要进一步研究。
The anatomy of the psoas major muscle (PMA) in young black and white men was studied during routine autopsies. The forensic autopsies included 44 fresh male cadavers (21 black, 23 white) with an age span of 14 to 25 y. The range for weight was 66-76 kg and for height 169-182 cm. The PMA was initially measured in its entire length before measuring the diameter and circumference at each segmental level (L1-S1). At each segmental level, the calculated anatomical cross-sectional area (ACSA) was more than 3 times greater in the black group compared with the white (P < 0.001). The psoas minor muscle (PMI) was absent in 91% of the black subjects, but only in 13% of the white subjects. These data show that the PMA is markedly larger in black than white subjects. The marked race specific difference in the size of the PMA may have implications for hip flexor strength, spine function and race specific incidence in low back pathology, and warrants further investigation.
