This patient has multilevel cervical spondylosis and cervical radiculopathy. Cervical spondylosis is a chronic degenerative process of the intervertebral disks and facet joints. Degeneration of the cervical spine can lead to syndromes of axial neck pain, radiculopathy from nerve root compression, and myelopathy from cord compression. Spondylosis typically begins at age 40 years to 50 years and is more common in men than in women. The most commonly affected levels are C5-C6 and C6-C7, as these levels have the greatest motion with neck flexion and extension.1

A person with cervical spondylosis may present with neck pain with or without neurologic symptoms. It is important to note that radiographic findings do not always correlate with patient complaints. For instance, degenerative changes are seen on radiographs in 70% of people by age 70 years, but not all people will be symptomatic.

Radiculopathy occurs when the nerve root is compressed by foraminal stenosis and/or a posterior lateral disk herniation. Cervical nerve roots 1 through 7 exit above the corresponding cervical vertebra, and the eighth cervical root exits below the C7 vertebrae. Therefore, a C5-C6 disk herniation affects the C6 nerve root, a C6-C7 disk herniation affects the C7 nerve root, and a C7-T1 herniation affects the C8 nerve root. This patient presented with weak intrinsic muscles and decreased sensation to the little finger of the hand, which most likely indicates a C8 radiculopathy.2
