Anterior cervical discectomy and fusion (ACDF) is one of the most commonly performed and most successful procedures in all of spine surgery. It reliably decompresses nerve roots and the spinal cord in the neck, relieves arm and hand pain from cervical disc disease, and has an excellent track record of long-term safety and effectiveness. For patients with cervical disc herniation, radiculopathy, or myelopathy who have not improved with conservative treatment, ACDF is often the most appropriate surgical option.
WHAT IS ACDF?
ACDF is performed through a small incision on the front of the neck. The diseased disc is completely removed, decompressing the nerve root or spinal cord. The disc space is then filled with a bone graft or interbody cage to maintain disc height and promote fusion. A small titanium plate and screws are typically placed across the front of the operated levels to stabilize the construct while the fusion heals. The treated level becomes permanently immobile once fusion is complete.
CONDITIONS TREATED
- Cervical radiculopathy — arm pain, numbness, or weakness from a herniated disc or bone spur compressing a nerve root
- Cervical disc herniation causing nerve or cord compression
- Cervical myelopathy — spinal cord compression causing hand clumsiness, gait problems, balance difficulties, or weakness
- Cervical spondylosis with radiculopathy or myelopathy from degenerative disc and bone spur disease
- Cervical instability requiring stabilization
WHO IS A CANDIDATE?
ACDF is appropriate for patients with symptomatic cervical disc disease who have failed conservative treatment for at least 6 weeks, except in cases of progressive neurological deficit or severe myelopathy where more urgent surgery is appropriate. Patients with kyphosis, instability, OPLL, or multilevel disease requiring more than 3 levels may be better served by posterior approaches or combined anterior-posterior surgery.
THE PROCEDURE
ACDF is performed under general anesthesia through a 2–4 cm transverse incision on the front of the neck. The natural tissue planes are followed to access the front of the cervical spine without cutting through muscles. The disc is removed under magnification, bone spurs compressing the nerve or cord are cleared, and an interbody cage or graft is placed. Intraoperative neuromonitoring provides continuous feedback throughout. The incision heals within the natural skin crease of the neck and becomes nearly invisible within weeks to months.
ACDF VS. CERVICAL DISC REPLACEMENT
Both procedures decompress the nerve or cord through the same anterior approach. The key difference is that ACDF fuses the treated level permanently, while disc replacement preserves motion. For patients who are candidates for disc replacement — those without kyphosis, significant facet arthritis, or instability — disc replacement offers advantages in adjacent segment protection at long-term follow-up. Dr. Sardar evaluates every patient for disc replacement candidacy and recommends the procedure that is genuinely best for that patient’s anatomy and goals.
FREQUENTLY ASKED QUESTIONS
How successful is ACDF?
ACDF has one of the longest and most well-established track records in spine surgery, with high fusion rates and reliable relief of arm pain and nerve-related symptoms in appropriately selected patients.
Will I lose neck motion after ACDF?
Yes, motion is permanently lost at the fused level, though most patients do not notice a significant functional difference for single or two-level fusions, since the remaining cervical segments compensate.
How many levels can be fused at once?
ACDF is most commonly performed at one to three levels. Beyond three levels, a posterior approach or combined surgery is often considered to reduce the mechanical demands placed on the anterior plate construct.
What if the fusion doesn’t heal?
A non-union, or pseudarthrosis, is uncommon but can occur, particularly with smoking or certain medical conditions. It is identified on follow-up imaging and may require revision surgery if it causes ongoing symptoms.
Will I need a neck brace after surgery?
Yes, a hardcollar may be recommended after ACDF.
How soon can I return to work?
Many patients return to desk-based work within one to two weeks. Physical jobs typically require four to six weeks, depending on the specific demands of the role.
WHY CHOOSE DR. SARDAR
Dr. Sardar performs ACDF as one of the most common procedures in his practice and is equally expert in cervical disc replacement, allowing him to recommend the genuinely optimal procedure for each patient. He completed a dedicated fellowship in artificial disc replacement at the Texas Back Institute and operates at the Och Spine Hospital at NewYork-Presbyterian, where intraoperative neuromonitoring is standard for all cervical procedures.
