Spinal stenosis is an abnormal narrowing of the spinal canal or neural foramen that results in pressure on the spinal cord or nerve roots. [6] Symptoms may include pain, numbness, or weakness in the arms or legs. [1] Symptoms are typically gradual in onset and improve with leaning forward. [1]
Spinal stenosis may also affect the cervical or thoracic region, in which case it is known as cervical spinal stenosis or thoracic spinal stenosis. Lumbar spinal stenosis can cause pain in the low back or buttocks, abnormal sensations, and the absence of sensation (numbness) in the legs, thighs, feet, or buttocks, or loss of bladder and bowel ...
This is a result of the vertebral artery becoming occluded as it passes up in the transverse foramen. The spinal joints become stiff in cervical spondylosis. Thus the chondrocytes which maintain the disc become deprived of nutrition and die. Secondary osteophytes may cause stenosis for spinal nerves, manifesting as radiculopathy.
Moderate-to-severe cases can cause radicular pain in the legs caused by nerve root compression. [5] The symptoms are usually exacerbated by upright posture and often, but not always, relieved by lying down. Postural headaches can be related to spontaneous spinal cerebrospinal fluid leaks. [6] However, in many patients, dural ectasia is ...
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.
Cervical spinal stenosis is one of the most common forms of spinal stenosis, along with lumbar spinal stenosis (which occurs at the level of the lower back instead of the neck). Thoracic spinal stenosis, at the level of the mid-back, is much less common. [2] Cervical spinal stenosis can be far more dangerous by compressing the spinal cord.

Hemivertebrae are wedge-shaped vertebrae and therefore can cause an angle in the spine (such as kyphosis, scoliosis, and lordosis). Among the congenital vertebral anomalies, hemivertebrae are the most likely to cause neurologic problems. [5] The most common location is the midthoracic vertebrae, especially the eighth (T8). [6]
