Case Report: Management of tibial fracture nonunion: a case study of treatment failure and lessons learned.
Article in Frontiers in surgery, 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
Concept of "mechanical-biological balance" is fundamental to successful fracture healing; disruption of either component can lead to healing failure. Fractures of the middle and distal tibia are commonly encountered in clinical practice, particularly when associated with comminution. Managing fracture nonunion requires a comprehensive assessment of infection status, skeletal alignment, bone defect, implant stability, and host biological characteristics. This case report aims to explore the etiological factors of tibial nonunion and to reflect upon the biomechanical mechanisms underlying internal fixation failure. The findings demonstrate that failure to restore structural stability rendered subsequent biological repair measures ineffective. Case presentation: A 49-year-old perimenopausal woman developed tibial nonunion after internal fixation with a medial locking plate, screws, and titanium cables for a comminuted mid-to-distal tibiofibular fracture. Despite subsequent revision with PRP injection and autologous iliac crest bone grafting without addressing the underlying mechanical instability, the nonunion persisted and ultimately resulted in plate fatigue fracture. Conclusion: This case underscores that mechanical stability is a prerequisite for the biological cascade of fracture healing. In the absence of an adequate mechanical environment, even the most advanced biological augmentation cannot ensure successful union.
