Percutaneous vertebroplasty (PVP) using 3D radiography guidance offers an accurate, safe, and convenient approach for treating back pain from vertebral fractures in elderly stroke patients, improving rehabilitation outcomes.

Area of Science:

  • Orthopedics
  • Radiology
  • Neurosurgery

Background:

  • Elderly stroke patients often experience debilitating back pain due to vertebral compression fractures.
  • These fractures can significantly impede rehabilitation progress.
  • Existing treatment methods may have limitations in accuracy and safety.

Purpose of the Study:

  • To evaluate the efficacy and safety of percutaneous vertebroplasty (PVP) guided by three-dimensional (3D) radiography.
  • To assess the feasibility of this technique in elderly stroke patients with vertebral compression fractures.

Main Methods:

  • Six PVP procedures were performed on 5 elderly stroke patients with vertebral compression fractures causing back pain.
  • Three-dimensional (3D) radiography was utilized to identify the optimal needle trajectory.

Published on: August 9, 2024

  • Magnetic resonance imaging (MRI) T1- and T2-weighted sequences were used to characterize the fractured vertebral bodies.
  • Polymethylmethacrylate (PMMA) was injected into the fractured vertebrae.

    • Main Results:

    • The 3D radiography allowed for precise identification of the safest trajectory through the lamina and pedicle to the vertebral body.
    • A 13-gauge needle was successfully advanced in all patients.
    • Significant improvement in back pain was observed post-procedure.
    • No major complications were reported during or after the PVP procedures.

    Conclusions:

    • Percutaneous vertebroplasty (PVP) under 3D radiography guidance is an accurate, safe, and convenient method for managing vertebral compression fractures.
    • This technique effectively alleviates back pain, facilitating improved rehabilitation in elderly stroke patients.
    • 3D radiography enhances procedural accuracy and safety in PVP.
