Coblation-assisted cementoplasty is a safe and effective treatment for painful vertebral body metastases, offering significant pain relief and avoiding complications. This technique enables precise polymethylmethacrylate deposition for advanced metastatic disease.

Area of Science:

  • Oncology
  • Interventional Radiology
  • Orthopedic Surgery

Background:

  • Vertebral body metastatic disease often causes severe pain and can lead to fractures.
  • Current treatments may have limitations in managing pain and structural integrity.
  • Percutaneous cement deposition techniques aim to stabilize fractures and alleviate pain.

Purpose of the Study:

  • To retrospectively evaluate the feasibility, safety, and efficacy of coblation and cementoplasty for treating painful advanced vertebral body metastatic disease.
  • To assess the technical success, imaging outcomes, complications, and palliative effects of the procedure.

Main Methods:

  • Fifteen patients with painful metastatic vertebral body fractures underwent percutaneous coblation followed by cementoplasty.
  • Coblation created a cavity for targeted polymethylmethacrylate deposition.

  • Patient records were reviewed for technical success, imaging, complications, and pain relief.

    • Main Results:

    • The procedure was technically successful in 14 out of 15 cases.
    • Imaging confirmed adequate cement deposition without extravasation or fracture progression.
    • All patients experienced significant pain relief with no reported neurological damage.

    Conclusions:

    • Coblation-mediated cavity creation prior to cementoplasty is a safe and effective method for treating vertebral metastases.
    • This technique facilitates precise cement deposition in patients with metastatic foci.
    • Further prospective studies comparing this approach to standard treatments are recommended.
