Imaging findings and complications after curettage of atypical cartilaginous tumors in long bones: a retrospective single-center cohort study.
Article in Skeletal radiology, 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
objectiveTo assess imaging findings and complications after curettage of atypical cartilaginous tumors (ACTs) in long bones. MATERIALS AND
methodsThis retrospective study included patients with central ACTs of long bones treated with curettage, adjuvants, and cementation or bone grafting, who had clinical and imaging follow-up data available for at least 2 years after surgery. All imaging studies (radiographs, CT, MRI) were independently assessed by three radiologists. Clinical information was collected from the medical records.
resultsSixty-eight patients were included (median age [interquartile range, IQR], 53 [45-60] years). Bone graft and cement were used in 53 (77.9%) and 15 (22.1%) patients, respectively. Prophylactic internal fixation was performed in 63 (92.7%) patients. The median (IQR) follow-up duration was 42 (30-64) months. Normal imaging findings were identified at follow-up in 45 patients (66.2%). Our reported complications included peri- (2.9%) and post-operative (8.8%) bone fractures, incomplete bone graft integration (24.5%, out of patients treated with bone grafting), cement loosening (26.7%, out of patients treated with cementation), fixation hardware rupture (1.6%) or loosening (6.3%, out of patients treated with internal fixation) and residual disease (1.5%). Incomplete bone graft integration and cement loosening were associated with tumor location in the humerus (p = 0.023). Inter-reader agreement ranged between moderate and excellent (Fleiss's K = 0.522-1).
conclusionAfter curettage of ACTs in long bones, complications are detected on follow-up imaging examinations in one third of patients, mainly including fractures, incomplete bone graft integration and cement loosening.
