Retrograde improvisations and their iatrogenic complications: a case report of an antegrade femoral nail used as a retrograde construct.
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
Intramedullary nailing is the standard of care for femoral shaft fractures. Antegrade nails are designed for proximal insertion, while retrograde nails are for distal insertion, deviation from this pathway can result in mechanical failure. We report a 47-year-old female who presented with left thigh pain, swelling, and restricted mobility. Clinical examination revealed thigh deformity and ecchymosis, with preserved distal neurovascular status. Radiographs demonstrated an intramedullary nail with hypertrophic malunion at the distal femur with a proximal periprosthetic fracture. Computerized tomography imaging confirmed cortical breaches by screws, and an oblique fracture near the proximal screw. Images were suggestive of the use of an antegrade nail through a retrograde construct. The malpositioned nail was removed and replaced using the appropriate proximal entry site. Postoperative radiographs confirmed stable fixation. The patient reported improved mobility with radiographic healing. This case highlights the consequences of incorrect implant orientation and the importance of surgical verification.
