本研究确定了头后小直肌（RCPMi）和寰枕后膜（PAO）之间软组织桥的变异、患病率、组织类型以及性别差异。对75具尸体（27具女性尸体和48具男性尸体）进行了研究。当发现RCPMi时，将其上方附着点分离，并将肌肉向下翻转，以确定它是否附着于下方的PAO。如果发现软组织桥，则通过目视检查将桥内的纤维分为三类：腱样、肌样和筋膜样。还记录了无附着的第四类情况。这些结果表明，在所有接受研究的尸体中，93%双侧存在RCPMi（女性尸体为89%，男性尸体为96%）。在右侧，67%的男性和78%的女性存在软组织桥。在左侧，69%的男性和82%的女性存在软组织桥。在软组织桥中含有腱纤维的男性尸体数量，右侧为56%，左侧为55%。在女性中，在软组织桥中含有腱纤维的尸体数量，右侧为44%，左侧为64%。在男性中，软组织桥中存在肌纤维的情况，右侧为34%，左侧为36%。在女性中，在软组织桥中发现肌纤维的情况，右侧为43%，左侧为36%。性别与软组织桥的存在以及软组织桥内纤维类型之间没有显著关联。
This investigation determined the variation, prevalence, tissue-type, and sex bias in the soft-tissue bridge between rectus capitis posterior minor (RCPMi) and the posterior atlanto-occipital membrane (PAO). Seventy-five cadavers (27 females and 48 males) were surveyed. When RCPMi was revealed, its superior attachment was detached and the muscle was reflected inferiorly to determine if it was attached to the underlying PAO. If a soft-tissue bridge was identified, the fibers found within the bridge were classified by visual inspection into three categories: tendon-like, muscle-like, and fascia-like. A fourth category of no attachment was also noted. These results show that RCPMi was present bilaterally in 93% of all cadavers surveyed (89% of the female cadavers and 96% of the male cadavers). On the right side, a soft-tissue bridge was present in 67% of males and 78% of females. On the left side, the soft-tissue bridge was present in 69% of males and 82% of females. The number of male cadavers possessing tendon fibers in a soft-tissue bridge was 56% on the right side and 55% on the left side. In females, the number of cadavers possessing tendon fibers in a soft-tissue bridge was 44% on the right side and 64% on the left side. In males, muscle fibers were present in the soft-tissue bridge, 34% on the right side and 36% on the left. In females, muscle fibers were found in the soft-tissue bridge, 43% on the right side and 36% on the left. There were no significant associations of sex and the presence of the soft-tissue bridge and a fiber-type within a soft-tissue bridge.
