What is cervical fusion (ACDF)?
Anterior cervical discectomy and fusion (ACDF) is an operation on the neck. Through a small incision at the front of the neck, the surgeon removes a worn or herniated disc that is pressing on a nerve root or the spinal cord, then fills the space with a bone graft or spacer so the two vertebrae gradually grow together, or fuse, into one solid segment. It is one of the more established procedures for cervical nerve or spinal-cord compression that has not settled with non-surgical care.
What happens during the procedure
ACDF is carried out under general anesthesia. Working through a small incision at the front of the neck, the surgeon gently moves aside the soft tissues to reach the spine from the front, which avoids cutting through the muscles at the back of the neck. The problem disc is removed to take pressure off the nerve or spinal cord. A spacer or bone graft is placed in the gap, and a small plate and screws are often added to hold everything steady while it heals. Most single-level procedures take a couple of hours.
Benefits and considerations
ACDF removes pressure from a nerve root or the spinal cord and stabilizes the treated level. Fusing a segment removes movement at that level, and changes can develop at neighbouring levels over time. Risks include hoarseness or difficulty swallowing, infection, bleeding, nerve or spinal-cord injury and non-union. In selected cases, cervical disc replacement or another decompression may be an alternative; this depends on the diagnosis and anatomy.
Recovery and what to expect
Discharge may be the day of surgery or after an inpatient stay, depending on swallowing, mobility, pain control and general health. The fusion is monitored over time. Your surgeon will guide wound care, collar use if needed, activity, driving and return to work. If fusion has been recommended, a second opinion can review the diagnosis, proposed levels and alternatives.
How we approach your care
- 01
Find the true source
We begin with a thorough history and examination, supported by imaging where appropriate, to pinpoint the precise source of the problem.
- 02
Consider appropriate options
Where clinically appropriate, we consider established non-surgical options before surgery. The plan depends on the diagnosis, symptoms, health and priorities of the individual patient.
- 03
A plan built around you
Every step is explained clearly, so you always understand your options and what comes next.
This may help if
- MRI shows a cervical disc or bone spur pressing on a nerve root or the spinal cord
- Arm pain, numbness, or weakness matches the level seen on your scan
- Neck-focused non-surgical care has not brought lasting relief
- Signs of spinal-cord compression (myelopathy) make earlier surgery sensible
Suitability can only be assessed after reviewing your symptoms, examination, relevant imaging and previous treatment.
Common questions
What is ACDF surgery?
ACDF stands for anterior cervical discectomy and fusion. Through a small incision at the front of the neck, the surgeon removes a worn or herniated disc pressing on a nerve or the spinal cord, then places a spacer or bone graft so the two vertebrae gradually join into one segment. It is a well-established option for cervical compression that has not settled with non-surgical care.
Will cervical fusion limit how I move my neck?
Fusing a segment removes movement at that level. The effect on overall neck movement varies with the number and location of levels treated and your movement before surgery. Your surgeon can explain what is expected in your case.
Is there a less invasive alternative to cervical fusion?
Sometimes. Depending on your anatomy and diagnosis, a motion-preserving cervical disc replacement, or a more limited procedure, may be suitable instead of a fusion. Non-surgical care remains the first step for many people. The right choice varies from person to person, which is exactly what an honest assessment of your MRI can clarify.
Should I get a second opinion before cervical fusion?
A second opinion can review whether your symptoms, examination and imaging support fusion and explain alternatives such as continued non-surgical care, disc replacement or a different decompression where appropriate.
How long is recovery after ACDF?
Length of stay and return to activity vary with the number of levels treated, your health and early recovery. The fusion is monitored over time. Your surgeon will guide driving, work and activity and explain how swallowing or voice changes will be followed.
What are the main risks of ACDF?
Risks include infection, bleeding, hoarseness, difficulty swallowing, nerve or spinal-cord injury and failure of the bones to join (non-union). Symptoms may also develop at a neighbouring level over time. Your surgeon will explain the likelihood and relevance of each risk for your case.
