The Effect of Sagittal Spinopelvic Parameters and Kinematics on the Morphology and Symptomatology of Femoroacetabular Impingement: A Systematic Review and Meta-analysis

Low PI was linked to pincer morphology, suggesting a primary prevention target during development. Cam hips with higher PI were predisposed to symptoms. Symptomatic cam FAI also showed diminished pelvic rollback and increased anterior pelvic tilt, identifying kinematic targets for conservative management. Finally, dynamic spinopelvic characteristics more consistently demonstrated significant differences than static ones and may be more clinically pertinent in FAI research.
