Cervical Deformity

This is a patient with a chin on chest deformity because of the abnormal curve in the neck and upper back.
This is a patient with a chin on chest deformity because of the abnormal curve in the neck and upper back.

The  neck is extremely flexible. This flexibility often puts the neck at risk for injury. Some injuries (such as a dislocation or fracture) can create a spinal deformity within the cervical canal.

A deformity of the spine in the cervical region shows itself as an abnormal curve or angulation in the normally smoothly curved neck. The cause is degenerative facet or disc disease at multiple levels. 

The normal neck alignment in the front to back view should be straight up and down and from the side, should display a backwards curve called a lordosis. The lordosis is caused by the trapezoidal shape of the discs. The bodies of the vertebra are square and stacking them up on top of each other without the discs and facets would form a straight tower.

If the discs or facets break down (and they normally do), but break down asymmetrically, an abnormal alignment occurs. If this breakdown occurs at only one level, the malalignment rarely causes an abnormal curve. If this breakdown occurs at multiple levels, a deformity of the spine will result. One level's abnormal angulation will add to the abnormal angulation above and below to cause a scoliosis or a cervical kyphosis (a loss of curve in the neck compared to the natural lordosis). These conditions appear as a curvature of the neck and are neck deformities that cause neck pain and instability.

Symptoms

A deformity of the spine that may cause a curvature of the neck often causes the head to be held in an unusual posture when the neck is in a "relaxed" position. Muscle contraction is needed to hold the head in a normal position with chin neutral and eyes level. Chronic muscle contraction causes a dull crampy type of neck pain that is relieved with lying down.

Pain from neck deformities such as cervical kyphosis, as well as from degenerative conditions, can occur in each segment. That is-a bad disc or facet can cause nerve compression, disc pain, instability, degenerative spondylolysthesis as well as central stenosis and myelopathy (see each section for description of that disorder). 

Treatment

Non-surgical

Standard conservative treatment for a cervical deformity includes physical therapy, Chiropractic treatment, medications, home traction, massage and injections when necessary.  

Surgical

There are many spine surgeries available today; surgical treatment depends upon the size of the cervical deformity present and what the underlying cause of neck pain is. It may be that the deformity by itself is not causing pain and it is a simple matter to fix a herniated disc or bone spurs compressing a nerve root. If deformity surgery is necessary, the surgery may be performed strictly from the front (an ADCF), from the back (a posterior fusion) or from both sides (a 360).
