Cervical Spine
Posterior Cervical Foraminotomy
A motion-preserving decompression of a pinched cervical nerve root through a small opening from the back of the neck — no fusion, no implant, no lost motion.
What it is
A posterior cervical foraminotomy enlarges the foramen — the small bony doorway a nerve root passes through as it exits the neck — from behind, through a small incision. Under the operating microscope, a few millimeters of bone and ligament are removed over the nerve, and a soft disc fragment compressing it from the side can be removed through the same opening.
Nothing is fused and nothing is implanted. The disc stays, the motion stays, and the anatomy of the neck is otherwise left alone. It is the cervical equivalent of the philosophy that runs through this practice: remove what is compressing the nerve, and nothing else.
Why this procedure when surgery is needed
For arm pain from a nerve pinched at the side of the spinal canal — a lateral disc herniation or a bone spur narrowing the foramen — a foraminotomy relieves the compression directly without the trade-offs of a fusion: no lost motion, no implant, no adjacent levels asked to carry extra load, and no months waiting for bone to heal.
The honest boundary: this operation treats compression at the side, not the middle. When the disc material sits centrally, when the spinal cord itself is compressed, or when the neck is unstable, an anterior operation (ACDF or disc arthroplasty) is the right tool, and we will say so. Patient selection is what makes this operation look good.
What to expect
Surgery typically takes about an hour.
Most patients go home the same day or after one night.
Neck and shoulder-blade muscle soreness is the main early symptom and settles over the first weeks.
No collar is needed; gentle range of motion is encouraged early.
Return to desk work in 1–2 weeks; driving when off narcotics.
Arm pain typically improves early; numbness or tingling from a long-compressed nerve can take weeks to months to settle.
Risks and what to expect
A foraminotomy is one of the smaller cervical operations, and avoiding a fusion avoids an entire category of risk — but working millimeters from a nerve root in the neck still deserves an honest accounting.
Expected, temporary effects
Neck and shoulder-blade soreness. Muscle soreness at the back of the neck and toward the shoulder blade for the first weeks, settling as the muscle heals.
Lingering numbness or tingling. A nerve compressed for months does not always quiet down immediately; some numbness or tingling can persist after the arm pain is gone and usually fades over weeks to months.
Serious risks
Recurrent or persistent symptoms. The same root can be pinched again by a new disc fragment or further bone overgrowth, and some patients ultimately need an anterior operation. The foraminotomy does not burn that bridge.
Nerve-root injury. Direct injury to the nerve root is rare but can cause new weakness, numbness, or pain. The operating microscope and careful technique are used to minimize this risk.
Dural tear (CSF leak). A small tear in the lining around the nerves can occur and is repaired at the time of surgery.
Instability. Removing too much of the facet joint can destabilize the level — which is why only a few millimeters of its inner margin are taken, and why patient selection excludes necks that are already unstable.
Infection. Wound or deeper infection is uncommon and is reduced with sterile technique and antibiotics when appropriate.

Prepare for this surgery
Recover from this surgery
Approach
- Small posterior incision, often with a tubular retractor to spare muscle
- Operating microscope for nerve visualization throughout
- A few millimeters of bone removed — the facet joint is preserved to protect stability
- Lateral disc fragments removed through the same opening when present
- Outpatient-pathway, multimodal pain control to minimize opioid use
Typical indications
- Cervical radiculopathy from foraminal stenosis or a lateral disc herniation
- Imaging that matches the arm symptoms, with compression at the side of the canal
- Failed appropriate conservative care
- Progressive weakness in the affected nerve distribution
- Recurrent single-root symptoms adjacent to a prior fusion, in select cases
Alternatives we considered
- Continued conservative care — therapy, traction, time — for tolerable or improving symptoms
- Epidural or selective nerve-root steroid injection for inflammatory flares
- ACDF when the compression is central or the cord is involved
- Cervical disc arthroplasty for select single-level disc disease
