Corpectomy
Removes part or all of a vertebral body to relieve pressure on the spinal cord or nerves, then rebuilds the front of the spine with a graft and stabilization.
What a corpectomy is
A corpectomy removes a portion of, or an entire, vertebral body — the solid block of bone at the front of the spine — along with the discs above and below it. It is chosen when the source of compression sits behind the vertebral body itself, where a discectomy or laminectomy alone cannot reach it. After removal, the gap is reconstructed with a strut graft or cage, and fusion with instrumentation restores support and alignment.
Through a carefully planned corridor, the vertebral body and adjacent discs are removed to free the spinal cord or nerves. The resulting space is filled with a structural graft or cage, and the segment is fused — usually with a plate, screws, and rods — so the spine heals into a single stable unit. Computer-assisted navigation may be used to place instrumentation precisely.
When a corpectomy may be considered
- Compression behind the vertebral body — bone spurs or thickened ligament pressing on the cord from the front, common in advanced cervical stenosis and myelopathy.
- Multi-level disease — when compression spans several segments, removing one or more vertebral bodies can decompress more completely than multiple discectomies.
- Fracture or deformity — selected burst fractures or collapsed vertebrae where the body itself must be removed and rebuilt.
- Failed prior surgery — revision settings where the front of the spine needs to be addressed directly, as part of a revision spine surgery plan.
By region
- Cervical corpectomy — approached from the front of the neck, similar to an ACDF; a plate typically secures the reconstruction.
- Thoracic corpectomy — used where the spinal cord has little room for error; often combined with posterior instrumentation for stability.
- Lumbar corpectomy — rebuilds the front column of the low back when the vertebral body cannot be preserved.
What to discuss at consultation
- Why corpectomy: what is compressing the cord or nerves and why a smaller operation would not address it.
- Alternatives: multilevel ACDF, posterior decompression and fusion, or nonoperative care where appropriate.
- Reconstruction plan: graft choice, instrumentation, and whether a combined front-and-back approach is needed.
- Risks: the specific risks of vertebral body removal and reconstruction, incomplete relief, and the individual risks of surgery.
Who is a good candidate
- Advanced cervical stenosis with myelopathy — compression pressing on the spinal cord from the front, where a discectomy or laminectomy cannot reach
- Multi-level disease — compression spanning several segments, where removing one or more vertebral bodies decompresses more completely than multiple discectomies
- Burst fractures or collapsed vertebrae — where the vertebral body itself must be removed and rebuilt
- Revision settings — where the front of the spine needs to be addressed directly after prior surgery
Recovery
Because a corpectomy is a larger reconstruction than a simple decompression, recovery is measured in weeks to months and includes activity restrictions while the fusion heals. Most patients are walking the day of or after surgery, with a structured return to activity guided by follow-up imaging.
Risks and how they are minimized
As a larger reconstruction, corpectomy carries specific considerations: incomplete relief of the compression, nonunion (the graft or cage not fully fusing), and hardware-related issues. Rare risks include nerve or vascular injury. For cervical corpectomy, performed through the front of the neck, temporary swallowing difficulty or hoarseness can occur and usually resolve as swelling settles. The two layers, labeled: symptom layer — in the randomized ventral-versus-dorsal CSM trial, dysphagia was reported in 41% of the ventral surgery group (Ghogawala et al., JAMA 2021). Complication layer — in the international AOSpine surgical cohort, dysphagia occurred in 2.3% of anterior-only procedures (Fehlings et al., J Neurosurg Spine 2012). C5 palsy after corpectomy specifically was 5.1% in the multicenter series (Nassr et al., Spine 2012). The construct data: fusion rates were 92.1% for corpectomy versus 97.6% for multilevel ACDF, with early hardware failure in 2.6% of the corpectomy group (Uribe et al., Eur Spine J 2009).

These are minimized through careful preoperative planning, computer-assisted navigation for precise instrumentation, and intraoperative neuromonitoring where indicated. Dr. Choi reviews the individual risk profile plainly at consultation.
Alternatives considered first
Most neck and back problems improve without an operation, and surgery is never the starting point. Where appropriate, nonoperative care comes first.
For surgical candidates with suitable anatomy, a multilevel ACDF or a posterior decompression and fusion may address the compression without removing the vertebral body.
Related procedures
- ACDF — the smaller anterior cervical operation, for one to three levels where the vertebral body can be preserved.
- Laminectomy — posterior decompression for patterns better approached from the back of the spine.
- Spinal fusion — the broader family of stabilizing operations corpectomy belongs to.
Conditions this procedure treats
This procedure is most often used for: Cervical stenosis, Cervical myelopathy, Burst fracture.
Frequently asked questions
What is a corpectomy?
A corpectomy removes part or all of a vertebral body — the solid block of bone at the front of the spine — along with the discs above and below it. It is chosen when the source of compression sits behind the vertebral body itself, where a discectomy or laminectomy alone cannot reach. The gap is then reconstructed with a strut graft or cage, and fusion with instrumentation restores support and alignment.
Why would a surgeon choose corpectomy instead of a smaller operation?
When compression comes from bone spurs or thickened ligament pressing on the spinal cord from the front — common in advanced cervical stenosis with myelopathy — or when disease spans several segments, removing the vertebral body decompresses more completely than multiple discectomies. It is also used for selected burst fractures and in revision settings where the front of the spine must be addressed directly.
Is a corpectomy done in the neck or the back?
Both, depending on the problem. Cervical corpectomy is approached from the front of the neck, similar to an ACDF, with a plate securing the reconstruction. Thoracic and lumbar corpectomies address the mid and low back, often with posterior instrumentation added for stability.

How long is recovery after a corpectomy?
Because it is a larger reconstruction than a simple decompression, recovery is measured in weeks to months, with activity restrictions while the fusion heals. Most patients are walking the day of or after surgery, with a structured return to activity guided by follow-up imaging.
What are the alternatives to corpectomy?
Depending on the diagnosis: multilevel ACDF, posterior decompression and fusion, or nonoperative care where appropriate. The consultation covers why a smaller operation would or would not address the specific compression, plus the reconstruction plan and the individual risks.
Does a corpectomy include a fusion?
Yes — reconstruction and fusion are built into the operation, not added later. Once the vertebral body is out, the spine has a gap that must carry load, so a cage or strut graft is fitted between the healthy vertebrae above and below, usually with a plate or screws to hold alignment while healing proceeds. Over the following months, bone is meant to grow through that construct and unite the segment — the fusion. Until it does, the hardware is a scaffold, which is why follow-up imaging checks its progress.
What are the risks of a corpectomy?
A frank list matters more than a reassuring one. General risks include bleeding, infection, blood clots, and reactions to anesthesia. Specific to this operation: injury to the spinal cord or a nerve root, which can mean new weakness or numbness; a tear of the dura, the membrane around the cord, leaking spinal fluid; the cage or graft shifting before the fusion matures; and the fusion failing to unite, which occasionally means another operation. An anterior neck approach adds temporary swallowing difficulty and, uncommonly, hoarseness. Your own risk profile is part of the consultation, in plain terms.
How long do you stay in the hospital after a corpectomy?
Plan on a short admission rather than a same-day discharge. Many cervical corpectomy patients stay one to three nights; thoracic and lumbar reconstructions, which are larger undertakings, often run longer. The milestones for going home are practical, not calendrical: pain controlled on oral medication, walking safely — stairs included, if your home requires them — and eating and drinking normally. A physical therapist usually walks with you before discharge to confirm the basics. Exact expectations for your level and approach are set at the preoperative visit, once the full plan is known.
Will I wear a brace after a corpectomy?
It depends on the level and the construct. After a cervical corpectomy, a rigid collar is commonly worn for roughly the first six weeks, coming off only for hygiene and meals, then weaned as early imaging confirms the reconstruction is holding. Thoracic and lumbar cases may use a removable brace for support during activity rather than around the clock. Braces are a temporary guardrail while bone healing is young — they do not substitute for the fusion itself. Your surgeon specifies the type and duration; wearing one longer than directed helps nothing.
What is the difference between a corpectomy and a discectomy?
Think of scale and target. A discectomy removes a disc — the cushion between two vertebrae — and is enough when the compression lives at that disc space, as in a straightforward ACDF (anterior cervical discectomy and fusion). A corpectomy goes a level deeper, removing the vertebral body itself along with the discs on either side, because the pressure sits behind that body where disc surgery cannot reach. Deeper access costs more recovery, so the smaller operation is preferred whenever it can accomplish the same decompression safely and completely.
