Intervertebral disc degeneration causes pain by leaking nucleus pulposus material and compressing nerves, leading to spinal stenosis. New therapies aim to restore disc biochemistry and structure.
Area of Science:
- Spine anatomy and physiology
- Intervertebral disc pathophysiology
- Degenerative disc disease
Background:
- The intervertebral disc, composed of nucleus pulposus, annulus fibrosus, and cartilaginous end-plates, connects vertebral bodies.
- The disc receives limited blood supply to end-plates and innervation via the sinovertebral nerve.
- Key biochemical components include collagen, elastin, and aggrecan.
Purpose of the Study:
- To review the anatomy, physiology, pathophysiology, and treatment of intervertebral discs.
- To elucidate the mechanisms of discogenic pain and spinal stenosis.
- To explore current and emerging therapeutic strategies.
Main Methods:
- Comprehensive literature review of intervertebral disc structure and function.
- Analysis of degenerative processes and their clinical manifestations.
- Examination of diagnostic protocols and treatment options.
Main Results:
- Disc aging leads to degeneration, loss of height, nucleus pulposus dehydration, and leakage of nociceptive material, causing discogenic pain.
- Degenerative disc height loss compresses adjacent structures, resulting in spinal stenosis and radicular pain.
- Diagnosis relies on a strict protocol, with various treatment options available.
Conclusions:
- Disc degeneration is a primary cause of back pain, spinal stenosis, and radicular pain in aging populations.
- Current and future treatments focus on biochemical restoration, nucleus augmentation, end-plate regeneration, and artificial disc replacement.
