Vertebroplasty effectively relieves pain in 89% of patients with spinal fractures. Implementing specific techniques can minimize complications like polymethylmethacrylate (PMMA) migration during this minimally invasive procedure.

Area of Science:

  • Neurosurgery
  • Interventional Radiology
  • Orthopedic Surgery

Background:

  • Vertebroplasty is increasingly used for spinal fractures and hemangiomas.
  • Complications, particularly polymethylmethacrylate (PMMA) migration, are a concern despite its minimally invasive nature.

Purpose of the Study:

  • To present methods and principles for minimizing PMMA migration and other complications during vertebroplasty.
  • To improve patient outcomes and safety in vertebroplasty procedures.

Main Methods:

  • Retrospective chart review of patients undergoing vertebroplasty.
  • Analysis of 53 vertebroplasty procedures on 35 patients over a 3-year period.
  • Inclusion criteria: disabling back pain from recent fracture, pharmacotherapy, anesthesia stability; follow-up at 2-3 weeks and 3 months.

Main Results:

  • Achieved an 89% success rate for pain relief.
  • Reported an overall complication rate of 6% per treated vertebral level.
  • Identified key factors for complication reduction: accurate needle placement, adequate PMMA radio-opacification, viscous low-pressure PMMA delivery, and direct fluoroscopic visualization.

Conclusions:

  • Vertebroplasty, while minimally invasive, carries risks of serious complications.
  • Adherence to specific procedural techniques is crucial for enhancing safety and efficacy.
  • Further research may focus on refining techniques to further reduce complication rates.
