INTRODUCTION

Neck pain is a common musculoskeletal symptom, accounting for millions of visits to physicians annually in the United States. Of individuals with neck pain, more than 80% are between the ages of 18 and 64 years. Mechanical disorders cause 90% of neck pain episodes. Mechanical neck pain is defined as that which is caused by overuse of a normal anatomic structure, by deformity of an anatomic structure, or by trauma (Figure 7–1). Mechanical disorders are characterized by exacerbation and alleviation of pain in direct correlation with particular physical activities. Neck pain due to mechanical disorders decreases within 2–4 weeks in more than 50% of patients, and symptoms usually resolve entirely within 2–3 months.

Schematic representation of a lateral view of the mid-cervical spine (A) and the superior aspect of C5 (B). The inferior articular processes from synovial-lined facet joints (also called apophyseal joints) with the superior articular processes of the vertebra below. The uncinate processes or posterolateral lips located on the superior aspect of the vertebral bodies interact with the inferolateral aspects of the vertebral body above, forming the small, nonsynovial-lined uncovertebral joints (also referred to as the joints of Luschka). The spinal cord lies within the vertebral foramen formed by the vertebral body anteriorly, the pedicles laterally, and the laminae posteriorly. The cervical nerve roots course along “gutters” formed by the pedicles and exit through an intervertebral foramen. The vertebral artery passes through the transverse foramen.

INITIAL EVALUATION

The goal of the initial evaluation is to differentiate patients with probable mechanical disorders from those with neck pain that requires more thorough immediate evaluation (Figure 7–2). A history and physical examination should be performed in all patients with new-onset neck pain. The neurologic portion of the examination is designed to determine whether there are any signs of cervical nerve root or cervical cord involvement (ie, spastic weakness, hyperreflexia, clonus, and positive Babinski signs).

The initial evaluation of the patient with neck pain.

Laboratory tests and imaging studies are not necessary during the initial evaluation of patients with probable mechanical neck pain. These tests, however, are indicated for patients whose history and physical findings suggest persistent compression of the spinal cord or nerve roots or raise the possibility of neck pain as a component of an underlying systemic disease.

History

The history should establish the onset, location, and character of the pain, and determine if the pain is associated with radiation to ...
