Does Compensatory Anterior Pelvic Tilt Decrease After Bilateral Periacetabular Osteotomy?

CONCLUSIONS: We found a modest reduction in anterior pelvic tilt after bilateral PAO. This finding suggests that acetabular reorientation affects pelvic position. In clinical practice, patients with acetabular dysplasia may compensate with dynamic and reversible changes in pelvic tilt. The PS-SI index is a reproducible tool to measure the height of the pelvic inlet as an assessment of pelvic tilt. In the future, clinical studies should evaluate the clinical implications of these radiographic findings, including the assessment of back pain, which although multifactorial may be influenced by pelvic tilt. LEVEL OF EVIDENCE: Level III, therapeutic study. PMID: 30998635 [PubMed - in process]
