Outcomes and Complications Associated With 191 Carbon Fiber Pedicle Screws in Spinal Oncology Patients.
Article in International journal of spine surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundCarbon-fiber-reinforced polyetheretherketone (CFR-PEEK) instrumentation is used in spinal tumor surgery owing to its reduced artifact on postoperative imaging.
objectiveTo evaluate the outcomes and complications associated with the use of CFR-PEEK instrumentation.
methodsThis 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.
resultsThirty-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 (
conclusionOur 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.
