<p><strong>What Is Spinal Stenosis?</strong></p>
<p>Spinal stenosis is a narrowing of the spinal canal, the cavity within the vertebral column through which the spinal cord and nerves pass. Nerves leaving the spinal cord are called nerve roots; they pass through the vertebral column via small canals. Arthritic changes that cause overgrowth of vertebral bones may compress the spinal cord or the nerve roots, impairing sensation and muscle strength in the affected portion of the body. Most common among people in their 50s and 60s, spinal stenosis affects the lumbar (lower back) portion of the spine more than the cervical (neck) region. Symptoms include pain, numbness, and weakness in the neck, arms, lower back, and legs. As a result of leg weakness, people are prone to falls. Because the nerves controlling the bladder emerge from the lower spine, spinal stenosis may also cause urinary incontinence.</p>
Cervical spinal surgery is used to correct the part of the spine in the neck, including problems with the bones (vertebrae), disks, and nerves.
Cervical spinal surgery
The cervical spine is part of the spine that runs through the neck area. It consists of seven vertebrae and eight pairs of spinal nerves (called C1 to C8). The two most common problems people have with the cervical spine are herniation and stenosis.
For detailed information on those conditions see:
Herniated intervertebral disk
The specific cervical spine surgery depends on what is causing the problem. The surgery is done while you are under general anesthesia (unconscious and pain-free).
If there is a single herniated disk, then the disk may simply be removed through a surgical cut that is made in either the front or the back of the body.
If more than one disk needs to be removed, the sp...
Alternative Names Tumor - spinal cord Symptoms The symptoms depend on the location, type of tumor, and your general health. Tumors that have spread to the spine from another site (metastatic tumors) often progress quickly. Primary tumors often progress slowly over weeks to years. Tumors in the spinal cord usually cause symptoms, sometimes over large portions of the body. Tumors outside the spinal cord may grow for a long time before causing nerve damage. Symptoms may include: Abnormal sensations , loss of sensation:
Especially in the legs (may be in the knee or ankle, with or without shooting pain down the leg) Cold sensation of the legs, cool fingers or hands, or coolness of other areas May worsen over time Back pain:
Gets worse over time In any area -- middle or low back are most common Is usually severe and not relieved by pain medication Is worse when lying down Is worse with strain, cough, sneeze May extend to the hip, leg, or feet (or arms), or all extremities May stay in the spine Fecal inc...
