In short

Thoracic corpectomy removes one or more vertebral bodies in the mid-back (thoracic spine), along with the adjacent discs, to decompress the spinal cord from the front. The resulting gap is reconstructed with an expandable titanium cage filled with bone graft, and supplemental posterior fixation with pedicle screws and rods provides long-term stability. It is used for thoracic burst fractures, vertebral tumors, and severe ossification of the posterior longitudinal ligament (OPLL) that cannot be safely decompressed from behind.

Key takeaways

Thoracic corpectomy removes the vertebral body to access and decompress anterior cord compression that cannot be reached from the back.
An expandable titanium cage replaces the removed vertebra and restores anterior column height, combined with posterior pedicle screw fixation for stability.
The procedure is most commonly performed for thoracic burst fractures with retropulsed bone fragments, vertebral tumors with cord compression, and severe OPLL.
Approach options include open thoracotomy (chest), costotransversectomy, or thoracoscopic (VATS) selected based on the level, laterality, and patient health.
Intraoperative neurophysiological monitoring is used throughout to protect the thoracic spinal cord.

THORACIC CORPECTOMY AT A GLANCE

Procedure type	Vertebral body removal and reconstruction with cage and posterior fixation
Approach	Thoracotomy, costotransversectomy, or thoracoscopic (VATS) level and pathology dependent
Anesthesia	General anesthesia with IONM; one-lung ventilation for thoracotomy/VATS
Surgery time	4 to 8 hours for combined anterior and posterior stages
Hospital stay	4 to 7 nights
Conditions treated	Thoracic burst fracture, vertebral tumor, OPLL, osteomyelitis with vertebral collapse
Reconstruction	Expandable titanium cage + posterior pedicle screw-rod fixation

Timing and stay vary by patient and complexity. Your surgeon will confirm what to expect in your case.

When thoracic corpectomy is needed

Thoracic corpectomy is reserved for situations where the primary source of spinal cord compression originates from the anterior column (the vertebral body or disc space) and cannot be safely removed from a posterior approach:

Burst fractures with retropulsion: High-energy thoracic fractures can drive bone fragments into the spinal canal from the front. When these fragments are causing cord compression and cannot be reduced from behind, corpectomy allows direct removal and immediate decompression.
Vertebral tumors: Primary spinal tumors (e.g., chordoma, giant cell tumor) or metastatic disease that has destroyed the vertebral body and is compressing the cord from the front requires corpectomy for decompression and stabilization.
Severe OPLL: Ossification of the posterior longitudinal ligament in the thoracic spine can cause severe anterior cord compression not amenable to posterior decompression alone.
Osteomyelitis with collapse: Vertebral infection causing significant collapse and anterior cord compression may require debridement, corpectomy, and reconstruction.

Reconstruction after thoracic corpectomy

After the vertebral body is removed, the spine must be reconstructed to maintain structural integrity:

Expandable titanium cage: An expandable mesh cage is sized to fit the corpectomy defect and expanded to restore the anterior column height. The cage is packed with bone graft to facilitate fusion across the defect.

Posterior pedicle screw fixation: Posterior instrumentation spanning at least two levels above and below the corpectomy level is added to provide a long lever arm of stabilization, prevent cage migration, and maintain alignment while fusion matures. This posterior stage is typically performed in the same operative session or as a same-day staged procedure.

The resulting 360-degree (circumferential) construct has high rates of fusion and durable long-term stability.

Benefits and risks

Potential benefits

Direct decompression of the spinal cord from the front the only reliable approach for anteriorly positioned compression
Immediate structural reconstruction restores spinal alignment and prevents progressive deformity
Combined 360-degree fixation provides durable long-term stability and high fusion rates
Effective for tumor, trauma, and infection cases requiring both decompression and reconstruction

Possible risks

Approach-related risks: pneumothorax, intercostal neuralgia, pulmonary complications for thoracotomy and VATS approaches
Neurological deterioration from cord manipulation mitigated by IONM
Longer operative time and hospital stay than posterior-only procedures
Hardware failure or cage subsidence in patients with poor bone quality or extensive tumor involvement

Your surgeon will review the benefits and risks specific to your diagnosis during your consultation.

What recovery looks like

Recovery from thoracic corpectomy is one of the most demanding in spine surgery:

Days 1 to 4 ICU or step-down monitoring. Chest drain in place for 1 to 2 days for thoracotomy/VATS. Walking with physical therapy begins within 48 to 72 hours.
Days 4 to 7 Discharge to home or short-term rehabilitation facility. A thoracolumbar brace is commonly prescribed.
Weeks 2 to 8 Outpatient physical therapy. Gradual increase in activity. Brace worn for most upright activity.
3 to 6 months Imaging confirms cage position and fusion progress. Full activity clearance when solid fusion is established.

Frequently asked questions

Is thoracic corpectomy ever done as a minimally invasive procedure?

Yes. Thoracoscopic (VATS) corpectomy uses small chest incisions and a camera system to perform the corpectomy through the chest without a full thoracotomy. It reduces chest wall morbidity significantly. However, it requires one-lung ventilation and a thoracic surgical team for access. Feasibility depends on the level, the patient’s pulmonary function, and the complexity of the reconstruction needed.

What is one-lung ventilation and why is it needed?

For thoracotomy and VATS approaches to the thoracic spine, the lung on the operative side must be deflated temporarily to allow the surgeon to see and work around it to reach the spine. This is managed by the anesthesia team using a specialized double-lumen endotracheal tube. The deflated lung is re-inflated at the end of the procedure.

How long does the cage last?

Expandable titanium cages used in thoracic corpectomy are designed for permanent implantation. Once solid bony fusion bridges the cage, the construct is structurally permanent. Cage failure rates are low when appropriate sizing, placement, and supplemental posterior fixation are used.

Can thoracic corpectomy be performed for cancer with spread to other parts of the body?

Yes. Thoracic corpectomy for spinal metastases can be performed even in patients with systemic cancer, provided the patient’s overall health and life expectancy support the recovery period. The goal in metastatic cases is typically stabilization, decompression, and pain control rather than cure — coordinated with oncology for post-operative systemic treatment.
