Dr. Charla Fischer, a board‑certified orthopedic spine surgeon in New York City whose practice focuses on the cervical spine, performs anterior cervical discectomy and fusion (ACDF). Sometimes more than one disc needs treatment. Here is what changes when an ACDF is done at two levels.
What Is a Two-Level ACDF?
A two-level ACDF treats two neighboring discs in the neck in one operation. As Dr. Fischer’s ACDF page explains, the spine is reached from the front of the neck through existing muscle planes. Each damaged disc or bone spur is removed, a graft or cage is placed between the vertebrae so they can heal together, and a plate may hold them in place while they fuse. At two levels, three vertebrae end up joined.
Who Needs It?
A two-level ACDF may be recommended when disc herniations or bone spurs at two adjacent levels are pinching nerves, typically causing arm pain, numbness or weakness that hasn’t improved with non-operative care. ACDF is also one of the options Dr. Fischer lists for cervical myelopathy, when the spinal cord itself is compressed.
One Level vs. Two Levels
| One-level ACDF | Two-level ACDF | |
|---|---|---|
| Discs treated | One | Two neighboring discs |
| Vertebrae joined | Two | Three |
| Approach | Front of the neck | Front of the neck |
| Hardware | Graft or cage, often a plate | Graft or cage at each level, often a plate |
What the Research Shows About Plates
A 2026 study of patients having two-level ACDF compared those who had a plate added with those who didn’t. At one year, patients with a plate had significantly less neck pain and better quality-of-life scores, while disability scores and arm pain were similar. The plate did not reduce the rate of cage settling (subsidence) or the need for another operation. Your surgeon decides whether to use a plate based on your anatomy and condition.
Recovery
For ACDF in general, most patients go home the next day, many return to work within three to six weeks with their surgeon’s approval, most are back to regular activities by three to four months, and the fusion becomes solid between six months and a year. Your surgeon will tell you how having two levels treated affects your own timeline. Dr. Fischer’s week-by-week ACDF recovery guide covers each stage.
Difficulty swallowing and hoarseness are recognized effects after ACDF because the surgery is done through the front of the neck. In the two-level study, no patient had swallowing difficulty that lasted more than three months.
Risks
Recognized risks of ACDF include difficulty swallowing, bleeding, infection, blood clots, a reaction to anesthesia, nerve damage, symptoms that don’t improve, and possibly needing more surgery in the future. Dr. Fischer reviews these, and why one or two levels are recommended, with each patient before surgery.
How to Get Help
If you’ve been told you need surgery at more than one level of your neck, a consultation can explain why, and what recovery would look like for you. Dr. Fischer sees patients at NYU Langone Center for Musculoskeletal Care, 333 East 38th Street, 6th Floor (646-501-7200), and NYU Langone Madison Orthopedic Surgery Associates, 145 East 32nd Street, 4th Floor (212-427-3986). Contact Dr. Fischer to schedule a consultation.

Frequently Asked Questions
What is a two-level ACDF?
It is an anterior cervical discectomy and fusion that treats two neighboring discs in one operation. Each damaged disc is removed, a graft or cage is placed, and the three vertebrae involved are allowed to fuse, often with a plate holding them in place.
Who needs a two-level ACDF?
It may be recommended when disc herniations or bone spurs at two adjacent levels are pinching nerves and causing arm pain, numbness or weakness that hasn’t improved with non-operative care.
Is a plate always used in a two-level ACDF?
Not always. A 2026 study found that patients who had a plate added had less neck pain at one year, but the plate did not reduce cage settling or the need for another operation. Your surgeon decides based on your anatomy and condition.
Is swallowing difficulty normal after a two-level ACDF?
Difficulty swallowing and hoarseness are recognized effects after ACDF because the surgery is done through the front of the neck. In the two-level study, no patient had swallowing difficulty lasting more than three months.
How long is recovery after a two-level ACDF?
For ACDF in general, most patients go home the next day, many return to work within three to six weeks, and the fusion becomes solid between six months and a year. Your surgeon will explain how two levels affects your own timeline.
