Anterior Cervical Discectomy & Fusion (ACDF)

Overview

What is ACDF?

Anterior Cervical Discectomy & Fusion (ACDF) is a well-established procedure used to treat spinal cord or nerve compression in the neck. The operation removes a damaged or herniated disc and immediately stabilises the spine with a fusion, aiming to relieve pain, restore function, and prevent further neurological deficit.

Who is it for?

ACDF is recommended for individuals with persistent neck and/or arm pain, numbness, or weakness caused by:

  • Cervical disc herniation
  • Cervical spondylosis (degenerative disc disease)
  • Cervical spinal stenosis
  • Spinal cord (myelopathy) or nerve root (radiculopathy) compression unresponsive to non-operative care.​

What the Procedure Involves

  • Anaesthetic: Performed under general anaesthesia.
  • Approach: A small incision is made in the front of the neck.
  • Discectomy: The surgeon gently moves aside muscles, trachea, and oesophagus to access the cervical spine. The damaged disc and any bone spurs compressing the nerves or spinal cord are removed.
  • Fusion: A spacer or cage – usually filled with bone graft – is placed where the disc was to maintain height and promote bone growth. Sometimes a small titanium plate is affixed for added stability.
  • Closure: The incision is closed and you are monitored in recovery.

Risks and Complications

While ACDF is generally safe, all surgeries carry some risks. Potential complications include:

  • Infection (1–2% risk)
  • Nerve or spinal cord injury (rare, but may result in neurological loss)
  • Bleeding or haematoma formation
  • Difficulty swallowing (dysphagia)
  • Temporary hoarseness or voice changes
  • Failure of the bones to fuse (pseudoarthrosis)
  • Implant movement or failure
  • Blood clots, chest infection, or cardiac complications (rare).

  • Implant movement or failure
  • Blood clots, chest infection, or cardiac complications (rare).

Recovery Expectations and Duration

  • Hospital stay: Usually 1–3 days.
  • Initial recovery: The first two weeks are focused on pain control and gentle activity.
  • Return to light activities: Most return to office work or gentle tasks by 2–6 weeks.
  • Physical therapy: May begin several weeks after surgery, to help restore strength and neck mobility.
  • Full recovery: 3–6 months is typical for most patients, with fusion continuing to mature for up to 12 months. Improvements in pain and nerve symptoms are often noticed early, but full recovery is gradual.

FAQs

Will my neck movement be limited after ACDF?
The fused segment will no longer move, but most people notice little change in their overall neck mobility, especially when only one or two levels are fused.

How soon will my symptoms improve?
Many people experience rapid relief of arm pain or numbness; neck pain and function gradually improve over weeks to months as nerves heal and fusion strengthens.
