Notes

The myodural bridge is a connective tissue structure that links the dura mater of the spinal cord to the cervical spine muscles. This anatomical feature plays a significant role in the biomechanics of the cervical region and has implications for headache and neck pain.

Anatomy

The myodural bridge is primarily composed of fibrous connective tissue. It extends from the rectus capitis posterior minor muscle to the dura mater, which is the outermost layer of the meninges surrounding the central nervous system. This connection is thought to stabilize the dura mater during movements of the head and neck.

Function

The myodural bridge is believed to help coordinate the movement of the dura mater with the cervical spine, potentially reducing mechanical stress on the nervous system. It may also play a role in the proprioceptive feedback mechanisms that help maintain posture and balance.

Clinical Significance

Research suggests that dysfunction or irritation of the myodural bridge may contribute to certain types of headache, particularly cervicogenic headache. This is due to the potential for altered tension or movement in the dura mater, which can affect neural structures and lead to pain.

Research and Studies

Studies have used MRI and cadaver dissection to better understand the structure and function of the myodural bridge. These studies aim to elucidate its role in biomechanics and its potential involvement in pathology.
