Liquid nitrogen-treated recycled autograft for reconstruction of a large tibial defect following wide resection of adamantinoma: a case report.
Article in International journal of surgery 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 and importance: Adamantinoma is a rare, low-grade malignant bone tumor with a predilection for the tibial diaphysis. Wide resection is the standard treatment, but reconstruction of large segmental tibial defects remains technically challenging. Liquid nitrogen-treated recycled autografts offer biological reconstruction, though experience with adamantinoma is extremely limited. Case presentation: A 36-year-old male presented with a 6-month history of progressive left tibial pain and swelling. Imaging revealed a 20-cm expansile osteolytic mid-diaphyseal lesion, confirmed histologically as adamantinoma. He underwent wide resection of a 25-cm tibial segment with liquid nitrogen devitalization (20-minute freezing at -196°C, 15-minute thawing, and 15-minute washing), followed by reimplantation with combined intramedullary nail and plate fixation, bone cement augmentation, autologous iliac crest grafting, and gastrocnemius flap coverage. Clinical discussion: Only two prior cases of LN2-treated recycled autograft for adamantinoma have been reported. This case demonstrates consistent outcomes and highlights the role of combined fixation, cement augmentation, and vascularized soft tissue coverage in achieving union over a 25-cm defect. Conclusion: Liquid nitrogen-treated recycled autograft with rigid fixation, cement augmentation, and vascularized soft tissue coverage achieves satisfactory oncological and functional outcomes in tibial adamantinoma. Lifelong surveillance remains mandatory.
