Summary
Percutaneous vertebroplasty significantly increases intravertebral pressure, a 13.6-fold rise compared to baseline venous pressure. This elevated pressure during bone cement injection may explain cement extravasation complications.
Area of Science:
- Spinal surgery
- Interventional radiology
- Biomaterials engineering
Context:
- Percutaneous vertebroplasty is a procedure to treat vertebral fractures.
- Extravasation of bone cement is a known complication.
- High injection pressures are suspected to cause cement leakage.
Purpose:
- To quantify the increase in intravertebral pressure during vertebroplasty.
- To compare intravertebral pressure to baseline ascending lumbar vein pressure.
Summary:
- A cadaver study measured intravertebral pressure during 19 vertebroplasties.
- Intravertebral pressure increased 13.6-fold compared to baseline venous pressure.
- A continuous pressure increase was observed during cement application cycles.
Impact:
- Findings suggest elevated intravertebral pressure is a potential cause of bone cement extravasation.
- This research may inform strategies to reduce cement leakage during vertebroplasty.
- Highlights the importance of pressure monitoring in vertebroplasty procedures.
