Greater anterior pelvic tilt and lumbar mobility in females compared to males undergoing periacetabular osteotomy: A matched cohort study.

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
Purpose: The functional hip-spine interaction is increasingly noted in hip preservation by periacetabular osteotomy (PAO), while potentially affecting the impingement-free acetabular reorientation. However, the clinically relevant sex-related differences in lumbopelvic alignment have been poorly studied. Thus, the purpose of this study was to evaluate a matched PAO patient cohort for sex-related differences in lumbopelvic alignment. Methods: Out of 138 patients undergoing PAO between January 2024 and September 2024 at one high-volume centre, there were 68 data sets (34 male, 34 female) included. The data sets of this diagnostic cohort study were prospectively collected, and the patients were matched in a 1:1 ratio for sex, age and acetabular morphology (hip dysplasia, borderline hip dysplasia, acetabular retroversion). Lumbopelvic alignment was assessed with serial sagittal lumbopelvic radiographs in standing, relaxed-seated and deep-seated positions. Each radiograph was reviewed for pelvic tilt (PT), lumbar lordosis and sacral slope. Results: Females showed a significantly lower PT in standing (7.8 vs. 14.3°, Conclusion: There are sex-related differences in functional lumbopelvic alignment across various positions of daily living in patients undergoing PAO. With a greater anterior PT, females are at risk of an anterior hip impingement. Thus, the intraoperative anterior and posterior wall reorientation by PAO should be adapted to the sex-related lumbopelvic alignment to ensure an impingement-free surgical outcome. Level of Evidence: Level IV, case series.
