1 · What the graph read from it

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.

2 · The registry

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

Introduction: Capitellum fractures are rare, representing only 1% of all elbow injuries. McKee Type 4 capitellum fractures encompass osteochondral shearing fractures of the capitellum, which involve a significant lateral portion of the trochlear ridge and the trochlea. These fractures may be linked with soft tissue and bone injuries surrounding the elbow, such as distal triceps tendon avulsion (DTTA) injuries. To date, only three case reports in the English literature have documented the correlation between Type 4 capitellum and trochlear fractures with DTTA injuries. Orthopedic surgeons should be vigilant for distal triceps and other posterior elbow injuries, which are often easily overlooked in the presence of prominent primary injuries at the front. The recommended method is prompt surgical intervention for these conditions; however, it is crucial to exercise careful judgment when deciding on the treatment and rehabilitation strategies for such cases. Case Report: We present a distinctive case in which an entire capitellum and trochlea were fractured as a single unit in the coronal plane (mimicking McKee type 4 capitellum fractures), along with a DTTA injury in a female patient in her late 40s. This injury was treated using open reduction and internal fixation with cannulated cancellous screws, along with the repair of the DTTA injury. Conclusion: This unique report provides a comprehensive overview of the pre-operative evaluations, reduction techniques, tendon repair, and post-operative rehabilitation process for such injuries, which showed a favorable outcome. The described fracture pattern has the potential to be categorized as type 5 fractures.
