Vertebral body replacement systems effectively stabilize the spine and improve neurological function in patients with vertebral destruction. This procedure offers pain reduction and functional recovery, despite a notable perioperative complication rate.

Area of Science:

  • Spine surgery
  • Orthopedic oncology
  • Neurosurgery

Background:

  • Vertebral body replacement aims to stabilize and restore the spine's anterior column after diseased segment removal.
  • Malignant vertebral destruction and instability from fractures necessitate effective treatment strategies.

Purpose of the Study:

  • To evaluate the efficacy of vertebral body replacement systems in stabilizing the spine.
  • To assess pain reduction and neurological improvement following the procedure.
  • To analyze perioperative risks and outcomes in patients undergoing vertebrectomy and replacement.

Main Methods:

  • A retrospective study involving 53 patients treated between April 1997 and December 2002.
  • Patients underwent vertebrectomy and vertebral body replacement using expandable titanium cages.

  • Outcomes were evaluated based on follow-up data regarding pain, neurological status, and complications.

    • Main Results:

    • Average follow-up was 18.9 months; mean operation time was 173.2 minutes.
    • Perioperative complications occurred in 34.0% of patients, with 2 deaths.
    • Pain reduction was reported in 52.7%, and neurological improvement in 48.0% of patients.

    Conclusions:

    • Vertebral body replacement systems provide adequate spinal stabilization.
    • The procedure can lead to significant pain reduction and neurological improvement.
    • Acceptable perioperative risk is associated with these systems for treating vertebral destruction.
