A novel screw-syringe compressor improves bone cement delivery during percutaneous vertebroplasty (VP). This device enhances control and prolongs injection time, offering a more effective treatment for vertebral compression fractures.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Interventional Radiology

Background:

  • Percutaneous vertebroplasty (VP) is a common treatment for osteoporotic vertebral compression fractures and spinal neoplasms.
  • Challenges in VP include increasing bone cement viscosity over time, leading to injection difficulties and limited procedural time.

Purpose of the Study:

  • To introduce a novel screw-syringe compressor designed to improve bone cement injection during percutaneous vertebroplasty.
  • To evaluate the efficacy and control offered by this new device in managing bone cement delivery.

Main Methods:

  • A specially designed screw-syringe compressor was utilized with a standard 10 mL Luer-Lok syringe and a short connecting tube.
  • The compressor was employed for injecting bone cement in patients undergoing percutaneous vertebroplasty.

Related Experiment Videos

Main Results:

  • The syringe compressor generated a maximum compression pressure of 2,772 psi.
  • It allowed precise control of cement delivery rate (0.2 mL/turn) and extended injection time up to 12 minutes.
  • The technique was successfully applied to 296 patients with 384 vertebral compression fractures.

Conclusions:

  • The screw-syringe compressor enables accurate and steady injection of bone cement, meeting physician requirements.
  • This device significantly improves control over bone cement injection during VP procedures.
  • The system offers the potential to reduce per-treatment costs.
