Surgery for cervical radiculopathy

Reviewed by Ryan Sauber, MD · Fellowship Director, AHN Orthopaedic Spine Fellowship · Last reviewed October 2026

When a pinched nerve in the neck doesn't settle down with time and non-surgical care, there are three main operations used to take the pressure off it: cervical disc replacement, anterior cervical discectomy and fusion (ACDF), and posterior cervical foraminotomy, which can now be done endoscopically. Each one relieves arm pain reliably when it's matched to the right problem. They differ in how they reach the nerve and in what recovery is like.

What the three operations share

The goal is the same in every case. Something is pressing on a nerve root as it leaves the spine, usually a piece of disc or a bone spur, and the operation makes room for that nerve again.

Arm pain tends to improve first and most predictably. Numbness and weakness recover more slowly, sometimes over months, and occasionally not completely if the nerve has been compressed for a long time. Neck pain on its own, without a pinched nerve, is not what these operations are built to fix. Symptoms and non-surgical treatment are covered on the cervical radiculopathy page.

The options side by side

Cervical disc replacement

The worn disc is taken out through a small incision in the front of the neck, the nerve is cleared, and an artificial disc is placed in the space. The level keeps moving instead of being fused. It is approved for one or two levels.

In my practice, disc replacement is done more often than ACDF. Patients go home the same day, and a soft collar is used for comfort rather than to protect anything. Not everyone qualifies: worn facet joints, instability, poor bone quality, or arthritis spread through many levels all point toward fusion instead. The full candidate criteria are on the cervical disc replacement page.

Anterior cervical discectomy and fusion (ACDF)

ACDF uses the same front-of-the-neck approach. After the disc and the compressing tissue are removed, a spacer fills the gap and the two vertebrae grow together into one solid segment over the following months. For decades it has been the most common operation for this problem in the United States, and it is very well studied.

ACDF handles situations disc replacement can't: three or more levels, a spine that isn't stable, or joints too arthritic to be worth preserving. A hard collar protects the neck while the fusion starts to heal. Most patients go home the same day, and patients having three levels fused stay one night. The trade-off is that the fused level no longer moves, which puts some extra load on the levels above and below over time. Fusion versus disc replacement goes through that decision in more detail.

Posterior endoscopic cervical foraminotomy

This is the newest of the three. The goal is simple: give the nerve more room. The surgeon works from the back of the neck through a small incision, using a thin camera and fine instruments. To get to the nerve, part of the lamina (the thin plate of bone covering the back of the spinal canal) and a small piece of the facet joint are removed. That opens up the foramen, the bony tunnel the nerve passes through.

Sometimes the disc fragment or bone spur pressing on the nerve can be taken out through the same opening, and sometimes it can't be reached safely from behind. Either way, the extra space is what takes the pressure off. Nothing is implanted and nothing is fused. Because the front of the neck isn't touched, the swallowing soreness that can follow the other two operations isn't part of recovery.

It fits a narrower group: arm symptoms on one side, coming from one nerve that is pinched off to the side of the spinal canal. It is not the right choice for a disc herniation in the center of the canal, for pressure on the spinal cord, for an unstable spine, or for problems at several levels. There is more on the technique on the endoscopic spine surgery page.

How the choice gets made

The decision comes from the MRI, the exam, and sometimes X-rays taken while bending. The main questions are where the pressure sits (centrally or off to the side), how many levels are involved, how healthy the facet joints are, whether the spine is stable, how good the bone is, and whether the spinal cord itself is under pressure.

Two patients with the same arm pain can have very different answers. A single bone spur narrowing one foramen and a two-level disc herniation pushing into the middle of the canal are different problems, and they get different operations. That's a decision to make with your imaging in front of you, not from a chart.

Recovery

Day of surgery

Most patients go home the same day. The exception is a three-level ACDF, which means one night in the hospital. After either front-of-the-neck operation, a sore throat and some difficulty swallowing are common for the first several days.

First two weeks

Walking starts right away. You'll wear a hard collar after ACDF and a soft collar for comfort after disc replacement. Arm pain often improves quickly. Numbness and tingling usually take longer.

Weeks to months

Return to work depends on the job and the operation, and desk work comes back well before heavy lifting. A fusion takes months to become solid, so restrictions on heavy activity usually last longer after ACDF than after disc replacement or foraminotomy.

Common questions

Talking it through

Cervical disc replacement and endoscopic spine surgery are the focus of my practice, and I still perform ACDF when fusion is the better answer. If you've been told you may need neck surgery and want to understand which option fits your imaging, I'd be glad to go over it with you at an appointment.
