Differences in pelvic tilt and spinal alignment according to age in patients with hip dysplasia

Puntos clave

This study aims to explore how pelvic tilt and spinal alignment differ by age in hip dysplasia patients.
Compared pelvic tilt during postural transition in younger and middle-aged patients.
Assessed functional acetabular coverage in a standing position during preoperative evaluations.
Identified pelvic tilt changes across age groups.
Younger patients exhibited a larger posterior change in pelvic tilt compared to middle-aged patients.
Preoperative assessment should focus on functional acetabular coverage, especially in younger patients.
Further longitudinal studies are recommended to investigate the effects on joint integrity.

Resumen

Younger patients with HD showed a larger posterior change in pelvic tilt during postural transition compared with middle-aged patients. These findings support preoperative assessment of functional acetabular coverage in the standing position, particularly in the anterosuperior region in younger patients, when planning ERAO. Longitudinal studies are needed to determine whether maintaining anterior pelvic tilt during standing contributes to preservation of joint integrity into middle adulthood.
