Posteriorly protruding cervical discs compressing the dural sac are very common in cervical spondylosis, where the neck is stimulated by constant acute and chronic injury to damage and rupture the annulus fibrosus, causing the nucleus pulposus within the annulus fibrosus to protrude posteriorly, thereby compressing the spinal cord, dural sac, or nerve roots. A lateral-posterior protrusion will compress the nerve roots, and a median-posterior protrusion will compress the dural sac. In this case, it is actually called central cervical disc herniation, and the symptoms of cervical disc herniation are those of central nerve damage, such as weakness of the limbs, loss of muscle strength, and even a feeling of stepping on cotton when walking, which may lead to quadriplegia in more severe cases. The herniated cervical disc presses backward on the dural sac, which is difficult to achieve through conservative treatment, and surgery is eventually chosen.
