Aneurysmal Bone Cyst of Calcaneum in a Young Adult: A Rare Case Report.
Article in Journal of orthopaedic 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
Introduction: Aneurysmal bone cyst (ABC) is a benign but locally aggressive osteolytic lesion that commonly affects long bones and vertebrae. Involvement of the calcaneum is rare and presents a unique diagnostic and therapeutic challenge due to its weight-bearing nature. Case Report: A 23-year-old male presented with pain in the left heel for 6 months, insidious in onset and progressive in nature, aggravated by weight bearing. Clinical examination revealed localized tenderness over the calcaneum. Radiographs showed an expansile osteolytic lesion with cortical thinning. Magnetic resonance imaging demonstrated a multiloculated cystic lesion with multiple fluid-fluid levels suggestive of ABC. The patient underwent extended curettage and autologous cancellous bone grafting and bone substitute. Histopathological examination confirmed the diagnosis of ABC. At 6 months follow-up, the patient was asymptomatic with no evidence of recurrence. Conclusion: Calcaneal ABC is a rare entity that should be considered in young patients presenting with chronic heel pain. Imaging aids in diagnosis, but histopathology is mandated. Extended curettage with bone grafting is an effective treatment option with good functional outcomes and low recurrence rates.
