Neck Pain – Samir Khan
Background
- Neck pain has a prevalence of 10 to 20 percent in the adult population
- The most common cause of neck pain in adults: Degenerative changes of the cervical spine
- Most atraumatic neck pain does not require imaging
Presentation
- Cervical muscle strain: pain + stiffness with movement 2/2 muscular injury
- Degenerative disc disease/osteoarthritis: pain + stiffness with movement from derangement in disc architecture leads to inability to distribute pressure in the joint
- Cervical Radiculopathy: neuropathic pain, sensory abnormalities, and/or weakness in an upper extremity (often radiating to hand)
- Cervical myelopathy: spinal cord compression causing neurologic dysfunction
- Earliest symptom is gait disturbance. Pain is uncommon
- Non-cervical conditions: shoulder pathology, migraine/headaches, occipital neuralgia, torticollis, thoracic outlet syndrome, angina pectoris/MI, bony metastases, vertebral artery or carotid artery dissection, fibromyalgia, meningitis, transverse myelitis
- Posterior neck pain
- Axial only MSK (sprain vs degenerative disc disease)
- Axial + Extremity Pain -> Radiculopathy
- Anterior neck pain
- Common sources: esophageal, thyroiditis, carotidynia, lymphadenitis, Ludwig’s angina
- Red flags: recent trauma, lower extremity weakness, gait abnormality, bowel/bladder incontinence, fever, weight loss
Evaluation
- Determine MSK (axial pain) vs Radiculopathy/Myelopathy) vs Non-spinal
Provocation Tests of the Neck |
|||
Test |
Isolates |
Action |
Positive if |
Spurling’s test |
Cervical radiculopathy |
Downward pressure applied to top of head with extended neck and rotates to affected side |
Reproducible pain beyond shoulder Neck pain alone is not specific |
Elvey's upper limb tension test |
Cervical radiculopathy |
Head turn contralaterally, arm is abducted while the elbow extended |
Reproduction of symptoms |
Hoffman sign |
Corticospinal lesion (UMN) |
Loosely hold middle finger and flick the fingernail downward, allowing the middle finger to flick upward reflexively |
There is flexion & adduction of thumb/index finger on the same hand |
- Imaging indications: Neuro deficits, Red flags, persistent pain (> 6 weeks)
- Cervical Plain films, 2-view (AP and lateral)
- Cervical MRI: visualizes spinal cord, nerve roots, bone marrow, discs and soft tissues
- Usually w/o contrast; can consider contrast if malignancy or infection suspected
- EMG/Nerve Conduction Studies: not routinely used for neck pain eval, but can be used to distinguish cervical radicular pain from peripheral causes of extremity dysesthesia
Management
- Cervical strain, Cervical radiculopathy: Physical therapy
- 5 d course of oral prednisone 60-80 mg, followed by 7-14 day taper
- Anti-spasmodic prn: Flexeril or Robaxin
- If not improving or progressive symptoms refer to Ortho Spine + PM&R
- Cervical myelopathy urgent surgical evaluation
