Biological reconstruction in the growing child after tumour resection: long-term outcomes of vascularized fibular epiphyseal transfer.

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
purposePaediatric limb-salvage surgery after tumour resection is challenging because reconstruction must account for small skeletal dimensions, immature bone, and residual growth. This study aimed to evaluate the long-term clinical, radiological, functional, and oncological outcomes of vascularized fibular epiphyseal transfer (VFET) after paediatric oncological resection.
methodsWe retrospectively reviewed nine children who underwent VFET between 1995 and 2025 at two institutions. Surgical techniques, bone union, graft hypertrophy, neo-joint remodelling, growth-related changes, complications, functional outcomes, and oncological status were analysed.
resultsThe mean age at surgery was 6.8 years (range, 2-14), and the mean follow-up was 105 months (range, 7-330). Reconstruction sites included the proximal humerus, proximal radius, proximal femur, and distal tibia. Mean resection length was 12.25 cm. Bone union was achieved in seven patients after a mean of 22 months. Graft hypertrophy was observed in all patients at one year, with a mean increase of 34%. Neo-joint remodelling occurred in three patients. Two patients developed proximal humeral graft overgrowth with instability and dislocation. Mechanical complications occurred in eight patients, mainly non-union and graft fracture. One-year complication-free survival was 33 ± 16%. Functional outcomes were better in the upper limb than in the lower limb. Three-year overall survival was 71 ± 18%.
conclusionsVFET is a demanding biological reconstruction option in growing children after tumour resection. Although graft hypertrophy and selected joint remodelling may occur, growth behaviour is unpredictable and mechanical complications are frequent.
