The myodural bridge was first described by Hack in 1995 and was thought to be related to chronic cervicogenic headaches. For a long time, few studies revealed the patterns of the myodural bridge considering the rectus capitis posterior minor muscle. In this study, P45 plastination technology and anatomical dissection were performed on head specimens, and four different terminal region types of the rectus capitis posterior minor muscle were observed, including the posterior atlanto-occipital interspace, posterior arch of the atlas and posterior atlanto-axial interspace. We propose that the myodural complex structures in the posterior atlanto-occipital and posterior atlanto-axial interspace have cooperative effects on cerebrospinal fluid and work together. This force might be an important source for the circulation of cerebrospinal fluid.
肌硬膜桥最早由哈克于1995年描述，被认为与慢性颈源性头痛有关。长期以来，很少有研究揭示考虑头后小直肌时肌硬膜桥的形态。在本研究中，对头标本进行了P45塑化技术和解剖 dissection，并观察到头后小直肌的四种不同终末区域类型，包括寰枕后间隙、寰椎后弓和寰枢后间隙。我们提出，寰枕后间隙和寰枢后间隙的肌硬膜复合结构对脑脊液有协同作用，并共同发挥作用。这种力量可能是脑脊液循环的重要来源。
