Clinical and radiological outcomes of magnetically controlled intramedullary lengthening nails in adolescents and young adults: a retrospective cohort study.
Article in Journal of orthopaedic surgery and research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundMagnetically controlled intramedullary lengthening nails offer a fully internal approach to limb lengthening, avoiding complications associated with external fixators such as pin site infections and soft tissue transfixation. While their use in adults is well-documented, evidence regarding their safety and efficacy in adolescents and young adults remains limited.
methodsThis retrospective cohort study evaluated the clinical and radiological outcomes of 24 limb lengthening procedures performed in 18 adolescent and young adult patients between 2022 and 2024 using PRECICE
resultsA total of 24 long bone segments (femur, tibia, and humerus) underwent lengthening in 19 sessions. The mean follow-up period was 18.8 months. The average length gained was 45.7 ± 10.5 mm, with a distraction rate of 1.0 ± 0.1 mm/day. Complications requiring return to the operating room occurred in 16% of cases, while 5.3% had minor unresolved issues at treatment completion. Radiographic analysis revealed favorable regenerate morphology, and no case showed regenerate insufficiency. Statistical comparison revealed a significantly higher distraction rate in femoral versus tibial lengthenings (p = 0.036).
conclusionsFully internal limb lengthening using magnetically controlled nails is a safe and effective option for adolescents and young adults, with a low rate of complications and high-quality regenerate formation. These findings support broader adoption of internal lengthening in younger patients, particularly in centers with trained teams and appropriate patient selection.
