Spondylosis
changes in the spine are frequently referred to as osteoarthritis. For example, the phrase "spondylosis of the lumbarspine" means degenerative changes such as osteoarthritis of the vertebral joints and degenerating intervertebral discs (degenerative disc disease) in the low back.
OVERVIEW
The word spondylosiscomes from the Greek word for vertebrae.
Spondylosis refers to degenerative changes in the spine such as bone spurs and degenerating intervertebral discs between the vertebrae.
Spondylosis changes in the spine are frequently referred to as osteoarthritis. 
For example, the phrase "spondylosis of the lumbar spine" means degenerative changes such as osteoarthritis of the vertebral joints and degenerating intervertebral discs (degenerative disc disease) in the low back.
Spondylosis can occur in the cervical spine (neck), thoracic spine (upper and mid back), or lumbar spine (low back). Lumbar spondylosis and cervical spondylosis are the most common.
Thoracic spondylosis frequently does not cause symptoms. Lumbosacral spondylosis is spondylosis that affects both the lumbar spine and the sacral spine (below the lumbar spine, in the midline between the buttocks).
Multilevel spondylosis means that these changes affect multiple vertebrae in the spine.
There are several medical terms that sound similar to and are often confused with spondylosis including the following:
Spondylitis is inflammation of one or more vertebrae, such as in ankylosing spondylitis, an inflammatory form of arthritis of the spine. This is a very different process than spondylosis because spondylosis is degenerative while spondylitis is inflammatory.
Spondylolysis is incomplete development and formation of the connecting part of the vertebra, the pars interarticularis. 
This defect predisposes to spondylolisthesis (see below) because of spinal instability.Spondylolisthesis is forward or backward displacement of the body of one vertebrae in relation to an adjacent vertebra. For example, anterior spondylolisthesis of L4 on L5 means that the fourth lumbar vertebra has slipped forward on the fifth lumbar vertebra. As a result, the spine is not normally aligned. If the displaced vertebrae shift with movement of the spine, this is referred to as dynamic spondylolisthesis. Dynamic shifting of the vertebrae is visualized with X-rays of the spine performed with patients flexing (bending forward) and then extending (bending backward) their back. Spondylosis deformans is growth of bone spurs (osteophytes) or bony bridges around a degenerating intervertebral disc in the spine. Spinal stenosis is narrowing of the spinal canal. This narrowing of the spinal canal limits the amount of space for the spinal cordand nerves. Pressure on the spinal cord and nerves due to limited space can cause symptoms such as pain, numbness, and tingling. Sciatica is pain shooting down the sciatic nerve as it runs from the low back down the buttock and the leg, either on one side or both sides. Sciatica often occurs when a herniated disc puts pressure on the sciatic nerve as it exits the spinal canal in the low back. Sciatica is a specific type of radiculopathy (compression or irritation of nerves as they leave the spinal column). Sciatica can be associated with spondylosis because the degenerative changes in the spine predispose to disc herniation and subsequent nerve compression.
About
A general term for age-related wear and tear of the spinal discs. changes in the spine are frequently referred to as osteoarthritis. For example, the phrase "spondylosis of the lumbar spine"means degenerative changes such as osteoarthritis of the vertebral joints.
Symtoms
Symptoms of cervical spondylosis with myelopathy include: Tingling, numbness, and/or weakness in the arms, hands, legs, or feet, lack of coordination and difficulty walking, Abnormal reflexes, Muscle spasms, loss of control over bladder and bowel(incontinence)
Causes
Treatment consists of self care and pain medications(no specific treatment is required). If symptoms occur, treatments include medication, corticosteroid injections, physiotherapy and sometimes surgery a general term for age-related wear tear of the spinal
Treatments
spondylosis is also called osteoarthritis. It is a condition involving changes to the bones, discs, and joints of the neck. These changes are caused by the normal wear-and-tear of aging. the discs of the cervical spine gradually break down, lose fluid, and become stiffer.
