Perilunate fracture-dislocation with scaphoid nonunion and ulnar nerve deficit in a young adult: a case report and review of the literature.
Article in Journal of surgical case reports, 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
Perilunate fracture-dislocations (PLFDs) are rare but severe wrist injuries. Median nerve involvement is common, whereas ulnar nerve injury is exceptionally rare. Delayed diagnosis remains frequent and negatively impacts outcomes. A healthy 30-year-old man sustained a fall onto his outstretched left hand, presenting with wrist deformity and ulnar sensory deficit. Radiographs showed disrupted Gilula's lines and a scaphoid waist fracture consistent with PLFD. Closed reduction failed, and open reduction with internal fixation via combined volar and dorsal approaches was performed, including carpal tunnel release, scaphoid fixation, ligament repair, and Kirschner wire stabilization. Postoperatively, ulnar sensation improved and carpal alignment was maintained, but scaphoid nonunion developed. The final Mayo Wrist Score was 75. PLFDs with ulnar nerve injury pose diagnostic and therapeutic challenges. Early comprehensive surgical management is essential, though complications may still occur, necessitating long-term follow-up.
