Rotational changes and associated risk factors following intramedullary nail fixation for intertrochanteric femoral fractures in elderly patients.

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
Objective: To quantify rotational displacement following intramedullary nail fixation for intertrochanteric femoral fractures using three-dimensional (3D) CT imaging, analyze associated risk factors, and evaluate its clinical significance. Methods: A total of 210 patients who underwent intramedullary nail fixation for intertrochanteric femoral fractures between 2020 and 2022 were included. All patients received postoperative 3D CT scans and were followed for at least 1 year. The range of postoperative femoral anteversion on the affected side was measured, and its correlation with risk factors was analyzed. Results: Among the 210 participants: six patients exhibited anteversion changes exceeding 15°; seven patients had anteversion changes between 10° and 15°; forty-three patients showed reduced anteversion (indicating increased external rotation of the affected limb), ranging from -1° to -14°, with a mean of -2.58°; in 103 patients, anteversion increased postoperatively, ranging from 1° to 22°, with a mean of 3.90°; sixty-four patients achieved restoration of normal anteversion. Single-nail fixation, poor reduction quality, medial cortical defects, Conclusion: Bone rotation and displacement are frequently observed following intramedullary nail fixation for intertrochanteric fractures. Numerous risk factors are closely associated with these complications. Therefore, meticulous attention to surgical technique is essential to minimize complications and optimize outcomes.
