There can be many causes of back pain including accidents, strains, and injuries. Two types of back injury are spondylolisthesis and cervical radiculopathy. Both have their own set of symptoms, causes, and treatments.

The spine, or backbone, is made up of a column of 33 bones and tissue extending from the skull to the pelvis. These bones, or vertebrae, enclose and protect a cylinder of nerve tissues known as the spinal cord. Between each one of the vertebra is an intervertebral disk, or band of cartilage serving as a shock absorber between the vertebrae. The types of vertebrae are:

• Cervical vertebrae: the seven vertebrae forming the upper part of the spine
• Thoracic vertebrae: the 12 bones between the neck and the lower back
• Lumbar vertebrae: the five largest and strongest vertebrae located in the lower back between the chest and hips
• The sacrum and coccyx are the bones at the base of the spine. The sacrum is made up of five vertebrae fused together, while the coccyx (tailbone) is formed from four fused vertebrae.

Some causes of back pain include accidents, muscle strains, and sports injuries.
How Is Back Pain Diagnosed?

In addition to performing a complete history and physical exam, your doctor may suggest one of the following diagnostic studies:

• X-rays, which can be used to provide detail of the bone structures in the spine and to check for instability (such as spondylolisthesis, see below), tumors and fractures.
• CT scans, which can identify specific conditions, such as a herniated disc or spinal stenosis.
• MRI scans, which can provide details about the backs discs and nerve roots. MRI scans are most commonly used for pre-surgical planning.
• CT scans, which can identify specific conditions, such as a herniated disc or spinal stenosis.

A number of other imaging and electrical studies may also be used to identify back problems, and some injections are used for diagnostic purposes as well as for pain relief.
