[Vertebroplasty and kyphoplasty:a review]

Area of Science:

• Spinal surgery
• Interventional radiology
• Orthopedic procedures

Context:

• Vertebroplasty (VP) and kyphoplasty (KP) are recent treatments for vertebral body (VB) lesions.
• Commonly used for osteoporotic fractures and metastases in selected patients.
• Involve polymethylmethacrylate (PMMA) injection into the VB via transpedicular cannulas.

Purpose:

• To describe the techniques of VP and KP.
• To highlight the favorable outcomes of these procedures.
• To advocate for a modified surgical approach using prophylactic interlaminar fenestration prior to VP to mitigate risks.

Summary:

• VP and KP involve injecting PMMA into the VB, with KP additionally using a balloon to restore VB height.
• These procedures offer favorable outcomes for treating vertebral body lesions.
• A prophylactic interlaminar fenestration before VP is proposed to prevent cement leakage and subsequent neurocompression.

Impact:

• Potential reduction in complications associated with VP and KP, such as cement leakage and neurocompression.
• Improved patient safety in the treatment of vertebral body lesions.
• Advancement in surgical techniques for spinal interventions, enhancing procedural safety and efficacy.
