Posterior Cervical Surgery (Fusion, Laminoplasty, Decompression)

Overview

What is Posterior Cervical Surgery?

Posterior cervical surgery includes a group of procedures—fusion, laminoplasty, and decompression—used to treat instability, nerve compression, or spinal cord compression in the neck (cervical spine). These techniques relieve pain, numbness, weakness, or problems with walking and balance caused by pressure on nerves or the spinal cord. Approaching the spine from the back (posterior) allows the surgeon to treat multiple vertebral levels if needed and to stabilise the spine using bone grafts and implants, when fusion is required.​

Who is it for?

Posterior cervical surgery is recommended for people with:

  • Cervical spinal stenosis (narrowing of the spinal canal)
  • Cervical myelopathy (spinal cord compression)
  • Persistent radiculopathy (nerve root symptoms)
  • Fractures, tumours, infection, or instability in the cervical spine
  • Significant deformity or multi-level disease not suitable for front (anterior) approaches
    Patients are usually those with severe symptoms or those who have not benefited from non-operative treatments.​

What the Procedure Involves

  • Under general anaesthetic, a midline incision is made in the back of the neck.
  • The muscles are gently moved aside to expose the spinal bones.
  • Decompression: The surgeon removes bone, disc, or thickened ligaments pressing on the spinal cord or nerves. This may involve a laminectomy (removal of lamina) or laminoplasty (reshaping or opening the lamina to widen the canal).
  • Fusion: If the spine needs stabilising, rods, screws, and bone grafts are placed to encourage the vertebrae to heal together. This provides long-term support and prevents further movement where necessary.​
  • The wound is closed, and you are monitored in recovery.

Risks and Complications

Risks of posterior cervical surgery can include:

  • Infection (around 2–4% risk)
  • Bleeding, blood transfusion
  • Injury to nerves or spinal cord (may cause weakness, numbness, or paralysis—rare)
  • C5 palsy (specific nerve-related weakness in arms)
  • Dural tear or spinal fluid leak
  • Wound complications or delayed healing
  • Non-union (fusion may not heal fully)
  • Hoarseness, difficulty swallowing (less common than with anterior approaches)
  • Increased mechanical stress on adjoining spinal segments, which may lead to wear (adjacent segment degeneration)​
    Most complications are uncommon but should be discussed with your spine surgeon and weighed against the benefits of surgery.

Recovery Expectations and Duration

  • Hospital stay is generally 1–7 days depending on the complexity and number of spinal levels treated.​
  • Neck discomfort and muscle soreness are common immediately after surgery, improving gradually in 6–12 weeks.​
  • Walking is encouraged as soon as possible, and simple pain relief helps.
  • At 2–6 weeks, light activities are allowed; ongoing improvement can be expected between 6–12 weeks, sometimes up to three months.
  • Physical therapy or rehabilitation may help restore neck and upper limb function and prevent stiffness.
  • Full bone healing (fusion) can take 6–12 months, with most patients seeing major symptom improvement by this stage.​

FAQs

Will my neck movement be limited after posterior cervical fusion or laminoplasty?
Fusion surgery will limit movement at the treated levels and may cause some reduction in total neck movement, but most daily activities remain manageable. Laminoplasty restores space for nerves and cord, often preserving more movement than fusion.

How soon will I notice symptom relief?
Many patients notice improvement in arm or hand symptoms soon after surgery, while neck pain and walking balance gradually improve over weeks to months. Ongoing recovery continues as nerves and muscles heal.
