Functional outcomes and quality of life following free fibula flap harvest: a comparative analysis of flexor hallucis longus resection versus preservation.

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
Background: The free fibula flap (FFF) is a gold standard for maxillofacial reconstruction, yet debate persists regarding the functional impact of flexor hallucis longus (FHL) resection. This study evaluates donor-site morbidity and quality of life (QoL) following FFF reconstruction, comparing outcomes with and without FHL resection. Methods: A retrospective analysis of prospectively collected data was conducted for 93 patients undergoing FFF reconstruction. Patients were stratified into FHL-harvested and non-FHL groups. Primary outcomes included QoL, AOFAS scores, hallux flexion strength, range of motion (ROM), isokinetic dynamometry, and gait analysis. Assessments were performed preoperatively and at 3- and 6-month intervals. Results: The study cohort comprised 93 patients, with FHL harvested in 43 cases. The FHL group exhibited transient declines in QoL at 3 months, with partial recovery by 6 months. Both groups showed similar AOFAS score trajectories, with temporary declines at 3 months and near-complete recovery by 6 months. Hallux flexion strength decreased comparably in both groups at 3 months (FHL: -38%; non-FHL: -34%), with residual 18-20% deficits at 6 months. Isokinetic testing revealed transient plantar flexion weakness in the FHL group at higher velocities (90°/s: 54.2 ± 7.0 Nm vs. 58.6 ± 7.5 Nm pre-op, p=0.008), resolving by 6 months. Gait analysis demonstrated initial impairments in stride length and ankle ROM in the FHL group, normalizing by 6 months. Conclusion: FHL resection during FFF harvest leads to transient functional and QoL impairments, but most deficits resolve within 6 months. Preservation is advisable when feasible, though FHL harvest remains safe for cases requiring additional soft tissue.
