Case of implant failure following osteosynthesis for an intertrochanteric femoral fracture using a carbon fiber intramedullary nail.
Article in Journal of surgical case reports, 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
Carbon fiber-reinforced polyetheretherketone (CFR-PEEK) materials are radiolucent and produce fewer metallic artifacts during radiological examinations, making them a subject of growing interest as osteosynthesis materials in the field of orthopedics. However, clinical reports on carbon intramedullary nails are still limited, and there are few reports on postoperative complications. The present case report describes a 55-year-old female patient who sustained an unstable intertrochanteric fracture of the left femur and underwent open reduction and internal fixation using a CFR-PEEK intramedullary nail. Ultimately, within just 6 months after the initial surgery, varus deformity developed at the fracture site, resulting in failure of the junction between the intramedullary nail and the lag screw, and necessitating revision surgery involving total hip arthroplasty.
