Functional and HIP survivorship outcomes of free Vascularized fibula graft in the management of post COVID-19 Osteonecrosis of femur head: A prospective case series.

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
Aim & objectives: To evaluate functional and radiological outcomes of Free Vascularized Fibula grafting in management of Covid-19 associated Osteonecrosis of Femur Head. Design: Prospective Case Series. Methods: 14 hips (10 patients) with ONFH following COVID-19 were treated with Free Vascularized Fibula graft from June 2021 to December 2022 and were subsequently evaluated monthly for 6 months and then every 3 months post operatively for functionality (Harris Hip Score), Femur head collapse and related complications. Results: Mean age of patients was 29.3 years (Range: 20-38 years). 14 diseased hips were classified on the basis of Steinberg classification as 4 stage 2B, 4 stage 3B and 6 stage 3C. The average follow up period was 2.1 years (Range: 12 months-34 months).Eight of fourteen hips survived and six progressed to collapse. Mean HHS at final follow-up was 68.3 in comparison to 65.8 pre-operatively. 4 fair and 4 poor HH scores were converted to 4 excellent and 4 good scores post-operatively.Two late complications were noted-one FHL contracture and one CPN neuroma. Conclusion: Free Vascularized Fibula Graft, as a hip salvage modality, showed optimal results in the treatment of COVID-19 related ONFH, which is associated with aggressive disease course and extensive involvement of femur head.
