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.
The degenerative process in osteoarthritis chiefly affects the vertebral bodies, the neural foramina and the facet joints (facet syndrome). If severe, it may cause pressure on the spinal cord or nerve roots with subsequent sensory or motor disturbances, such as pain , paresthesia , imbalance , and muscle weakness in the limbs.
Modic changes are pathological changes in the bones of the spine, the vertebrae. These changes are situated in both the body of the vertebrae and in the end plate of the neighboring disc. Clinically, Modic Changes are often associated with constant lower back pain during the day, with peak pain occurring during the night and in the morning ...
A lot of flexibility exists within the cervical spine and because of that, it is common for an individual to damage that area, especially over a long period of time. Some of the common cervical spine diseases include degenerative disc disease, cervical stenosis, and cervical disc herniation.
Forward displacement of a proximal vertebra in relation to its adjacent vertebra in association with an intact neural arch, and in the presence of degenerative changes, is known as degenerative spondylolisthesis, [9] [10] which narrows the spinal canal, and symptoms of spinal stenosis are common. Of these, neural claudication is most common.
The most common form of myelopathy in humans, cervical spondylotic myelopathy (CSM), [2] [3] also called degenerative cervical myelopathy, [4] results from narrowing of the spinal canal (spinal stenosis) ultimately causing compression of the spinal cord. [5] When due to trauma, myelopathy is known as (acute) spinal cord injury.
Cervical spine disorders are illnesses that affect the cervical spine, which is made up of the upper first seven vertebrae, encasing and shielding the spinal cord. This fragment of the spine starts from the region above the shoulder blades and ends by supporting and connecting the skull .
After the introduction of SCIWORA, the term was expanded to adults presenting with degenerative changes. Some authors used the term spinal cord injury without radiographic evidence of trauma (SCIWORET) to describe these cases. Furthermore, the introduction of computed tomography enabled a more detailed depiction of the spine.
