Overview

Cervical deformity refers to abnormal alignment of the neck spine, which may develop due to age-related changes, previous trauma, or degenerative disease. Deformity can cause neck pain, imbalance and may put pressure on the spinal cord or nerves. Treatment depends on the severity of symptoms and degree of cord compression.

Symptoms

  • Neck pain and stiffness, often worse with certain movements.
  • Visible forward head posture or uneven shoulder height.
  • Headaches, especially at the base of the skull.
  • Balance problems or unsteady gait.
  • Arm pain, numbness or weakness (if nerves are compressed).
  • In severe cases, difficulty with fine hand movements or walking.

Causes

  • Degenerative disc disease: loss of disc height and bone spur formation leading to kyphosis (forward curvature).
  • Osteoarthritis: facet joint and vertebral body changes causing alignment loss.
  • Previous trauma or fracture: old injuries that healed in an abnormal position.
  • Inflammatory conditions: ankylosing spondylitis or other systemic conditions.
  • Postural stress: prolonged poor posture contributing to alignment changes over time.

Diagnosis

  • Clinical assessment: posture evaluation, neck range of motion, neurological examination.
  • X-rays and CT: assess the degree and type of deformity; show bone alignment and structure.
  • MRI: evaluates spinal cord and nerve compression; assesses soft tissue and disc changes.
  • Imaging measurements: specialised measurements (e.g. cervical sagittal balance) guide treatment decisions.

Non‑surgical treatment

For mild to moderate deformity without significant cord compression or symptoms, conservative care may be effective.

  • Postural exercises and education: targeted exercises to improve neck strength and posture.
  • Physiotherapy: neck mobility, upper back strengthening, and ergonomic modification.
  • Pain management: NSAIDs, neuropathic pain medicines and muscle relaxants as needed.
  • Neck support: collar or brace for temporary relief during acute episodes.
  • Activity modification: avoiding positions that worsen symptoms or increase strain.

Regular monitoring with imaging may be recommended to assess for progression.

Surgical treatment

Surgery is considered when deformity causes significant pain, neurological symptoms, progressive cord compression or functional impairment.

  • Anterior cervical fusion: removal of affected discs and/or bone spurs via the front of the neck with fusion.
  • Posterior fusion: stabilisation from the back, particularly for kyphotic deformities.
  • Hybrid approaches: combining decompression and fusion to restore alignment while preserving some motion.
  • Realignment surgery: may involve vertebral osteotomy (bone cuts) to restore normal neck curvature in severe cases.

The choice of approach depends on deformity pattern, cord compression location and overall neck stability.
