BACKGROUND: Carbon-fiber-reinforced polyetheretherketone (CFR-PEEK) instrumentation is used in spinal tumor surgery owing to its reduced artifact on postoperative imaging.
OBJECTIVE: To evaluate the outcomes and complications associated with the use of CFR-PEEK instrumentation.
METHODS: This case series reviews 35 patients who underwent surgery using CFR-PEEK instrumentation between December 2020 and April 2025 at 2 academic institutions. Variables collected included demographics, cancer type, tumor location, tumor histology, surgical technique (open vs minimally invasive), and mortality at the latest follow-up. Categorical variables were described with frequencies, while continuous variables were described with means and SDs.
RESULTS: Thirty-five patients underwent 36 CFR-PEEK instrumentation procedures, utilizing a total of 191 screws. Patients had a mean age of 60.97 years (range: 15-83 years), and 23 patients (65.7%) were men. Thirty-one patients (88.6%) had metastatic spine tumors, with most tumors affecting the thoracic spine (51.4%). The most common histologies were multiple myeloma (n = 5) and lung cancer (n = 5). Twenty-two (66.6%) patients had a pathological fracture, while 16 (45.71%) had spinal cord compression on initial presentation. The mean estimated blood loss was 547.1 mL (range: 70-2000 mL). There were 1 intraoperative and 6 postoperative complications. One surgical revision was necessary due to a symptomatic screw. Median follow-up time was 5 months. The mortality rate at the latest follow-up was 40% (n = 14).
CONCLUSION: Our experience with CFR-PEEK implants demonstrates outcomes comparable to titanium implants. While CFR-PEEK facilitates the detection of local recurrences more quickly, long-term, large-scale studies are necessary to assess its cost-effectiveness.
CLINICAL RELEVANCE: This case series describes the use of carbon fiber instrumentation in patients with spinal tumors and encourages future studies to compare it with other instrumentation methods.
