Spinal Disc TearSymptoms, Causes, and General Information
Spinal discs are comprised of a tough fibrous outer layer (annulus fibrosis) and a water and protein mixture (nucleus pulposus). When the fibrous outer layer undergoes a significant trauma or deteriorates due to overuse, small tears can occur causing the fluid to leak out of the disc. This is referred to as an annular tear or a disc tear. These tears can occur in both the cervical and lumbar spine. Typically, there are three distinct types of annular tears:
- Radial Tear – Caused by the aging process and may lead to herniation of the disc.
- Concentric Tear – Often caused by sudden trauma or injury to the spine.
- Peripheral Tear – Often caused by injury and may cause the disc to break down over time.
Cervical Disc Tear symptoms would include:

- Having trouble gripping with hand
- Difficulty rotating neck
- The type of pain varies from dull to sharp
Lumbar Disc Tear symptoms would include:
