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

We report two cases of implant removal failure following internal fixation of femoral neck fractures using the Prima Hip Screw Side Plate (PHS-SP) system. Case 1 involved an 80-year-old woman with stripped screw heads, which prevented standard screw removal. The femoral neck was osteotomized, and the screws were severed to allow removal of the plate. Case 2 involved a 50-year-old man in whom a screw was firmly lodged in the barrel of the implant, making extraction impossible. The protruding screw was excised, and a second operation was later performed to cut the femoral neck and remove the implant. Conclusion: In both cases, implant removal required osteotomy of the femoral neck and mechanical destruction of the screws. These cases highlight the potential for implant removal failure in locking plate systems, and the importance of preoperative planning and patient counseling.
