Cervical discectomy and fusion (ACDF): neck surgery explained

Wear and tear in the neck, or a slipped disc, can press on a nerve root in the neck, causing arm pain, tingling or weakness, or on the spinal cord itself, causing heaviness in the limbs and clumsiness. The NHS says surgery is considered when a nerve is pinched by a slipped disc or bone (cervical radiculopathy) or when there is a problem with the spinal cord (cervical myelopathy), and adds that surgery is not always a cure but may stop symptoms getting worse.

Neck pain alone is a poor reason for this operation. The NHS neck-pain page describes painkillers, heat or cold packs, a low firm pillow and flexibility exercises, with a GP review if pain lasts beyond a few weeks.

For arm pain from a trapped nerve, a trial of physiotherapy, painkillers and time is common, because many episodes ease. The NHS describes exercises, usual activities as far as possible, painkillers and, for chronic pain, other medicines. Where the spinal cord is affected, a delay can matter more, so the timing of the decision is a discussion with a specialist.

• A supervised physiotherapy and exercise programme for arm pain from a trapped nerve.

• Pain-relief medicines, including those for nerve pain, discussed with your GP.

• Other operations, such as a disc replacement, which some surgeons offer for selected patients; ask whether you are suitable.

Hull advises stopping smoking before anterior neck surgery because it may increase the risk of voice change, and it also helps bones to join. Pre-assessment covers medicines, allergies and fasting for general anaesthetic.

It is helpful to plan some voice rest and to have pen and paper or a phone for typing, as Hull suggests, and to arrange help for the first days. If a collar will be fitted, practise sleeping and getting out of bed in a way that keeps your neck supported.

The operation is done under general anaesthetic. The surgeon works from the front of the neck, removes the damaged disc to free the nerve or cord, and joins the neighbouring bones. Royal Berkshire describes any combination of bone graft, metal plates or screws for the fusion.

After waking you are seen by a physiotherapist, who assesses mobility and shows exercises. Royal Berkshire says people with arm pain only often go home within 24 hours, while those with cord compression usually recover more slowly. Exact length of stay depends on your hospital.

Operating at the front of the neck can affect the structures that carry swallowing and voice. Hull says in the majority of cases this improves and recovers fully, but some people continue to have persistent swallowing or voice problems and may need Speech and Language Therapy. It advises reporting coughing or throat-clearing on saliva, fluids or food.

Other recognised risks include infection, bleeding, nerve injury, failure of the bones to fuse and persistent symptoms; the pages retrieved did not give percentages for these, so none are quoted. Ask your surgeon about their own results and about how any airway or neck swelling would be managed.

Royal Berkshire says a collar, if fitted, is worn for the first 4 to 6 weeks, never to drive while wearing it, avoid heavy lifting for three months, physiotherapy after collar removal or at 2 to 4 weeks if no collar, and surgeon review at 6 to 8 weeks.

Return to work depends on the job: desk work may feel comfortable at 6 to 8 weeks and heavy manual work is likely to need a minimum of three months, per the same leaflet. The recovery timeline page sets this out step by step.

The NHS says to call 999 for new walking problems, loss of bladder or bowel control, sudden loss of coordination, a drooping face, inability to lift both arms or difficulty speaking, and to call NHS 111 for severe neck pain that starts suddenly or worsens quickly, or for heaviness or weakness in the arms or legs. After surgery, difficulty breathing or a rapidly swelling neck needs 999. Wound redness, discharge or fever should be reported to the hospital or GP.

• Is my problem a pinched nerve or pressure on the spinal cord?

• How many levels will be fused and with what materials?

• Will I need a collar, and for how long?

• What is my chance of swallowing or voice change, and who helps if it occurs?

• How will we know if the fusion has healed?

The operation is much the same wherever it is done. NHS spinal teams often discuss complex neck cases in a group before offering surgery, while private care may offer an earlier date and a choice of surgeon. Ask who covers emergencies if a problem develops at night and what follow-up imaging and physiotherapy are included.
