  2. Disc protrusion - Wikipedia

    en.wikipedia.org/wiki/Disc_protrusion

    Spinal disc protrusion visible in MRI [1] A disc protrusion is a medical condition that can occur in some vertebrates, including humans, in which the outermost layers of the anulus fibrosus of the intervertebral discs of the spine are intact but bulge when one or more of the discs are under pressure.

  3. Disc herniation - Wikipedia

    en.wikipedia.org/wiki/Disc_herniation

    Disc herniation is normally a further development of a previously existing disc protrusion, in which the outermost layers of the annulus fibrosus are still intact, but can bulge when the disc is under pressure. In contrast to a herniation, none of the central portion escapes beyond the outer layers.

  4. Degenerative disc disease - Wikipedia

    en.wikipedia.org/wiki/Degenerative_disc_disease

    Degenerative disc disease (DDD) is a medical condition typically brought on by the aging process in which there are anatomic changes and possibly a loss of function of one or more intervertebral discs of the spine. [1] DDD can take place with or without symptoms, but is typically identified once symptoms arise.

  6. Lumbar disc disease - Wikipedia

    Lumbar disc disease is the drying out of the spongy interior matrix of an intervertebral disc in the spine. Many physicians and patients use the term lumbar disc disease to encompass several different causes of back pain or sciatica. In this article, the term is used to describe a lumbar herniated disc.

  7. Back injury - Wikipedia

    en.wikipedia.org/wiki/Back_injury

    Surgery is considered when symptoms persist after attempting conservative treatment. It is estimated 10-20 percent of individuals with low back pain fail to improve with conservative measures. [22] A discectomy is a common procedure used to alleviate the radiating pain and neurological symptoms associated with a herniated disc. [23]

  8. Failed back syndrome - Wikipedia

    en.wikipedia.org/wiki/Failed_back_syndrome

    CT scan image of large herniated disc in the lumbar spine. Removal of a disc at one level can lead to disc herniation at a different level at a later time. Even the most complete surgical excision of the disc still leaves 30–40% of the disc, which cannot be safely removed. This retained disc can re-herniate sometime after surgery.

  9. Spinal disease - Wikipedia

    en.wikipedia.org/wiki/Spinal_disease

    Symptoms for spinal tumors may vary due to factors such as the type of tumor, the region of the spine, and the health of the patient. Back pain is the most common symptom and it can be a problem if the pain is severe, has a time frame that lasts longer than it would for a normal injury, and becomes worse while laying down or at rest.
