What Is It?

Vertebral implants are minimally invasive devices used to restore vertebral body integrity, improve stability, and in selected cases achieve partial height restoration.

Unlike standard cement techniques, implants (such as expandable systems) provide internal structural support, allowing a more controlled reconstruction of the vertebral body before cement augmentation.

Indications

• Vertebral compression fractures with significant collapse

• Pathological fractures due to metastases or myeloma

• Failure or suboptimal response to vertebroplasty / kyphoplasty

• Complex vertebral instability

Role in Interventional Oncology

In oncologic patients, vertebral implants are often used in combination with cementoplasty and tumor ablation to:

• Reinforce structurally compromised vertebrae

• Improve biomechanical stability

• Reduce the risk of further collapse
• Optimize local disease management

They are particularly useful in more advanced or structurally complex lesions.
