Use of carbon fiber-reinforced PEEK cages in spinal oncology patients: An institutional experience with emphasis on surgical, complication and imaging characteristics.

ABSTRACT:

Purpose

Radiolucent carbon fiber-reinforced PEEK (CFRP) pedicle screws have improved imaging and radiation planning in spine oncology. However, these benefits are often limited by titanium cages used in combination. This study reports our initial experience using novel CFRP cages in oncologic spine surgeries, comparing their surgical feasibility, complications, and imaging performance to titanium cages.

Methods

We retrospectively analyzed 13 patients who received CFRP cages between July 2021 and May 2023. Clinical, surgical, follow-up, and imaging data were evaluated. A matched cohort with titanium cages was used to assess postoperative MRI visibility of anatomical landmarks, rated by independent reviewers.

Results

Thirteen CFRP cages were implanted (mean age 61 ± 11
