Does Periacetabular Osteotomy Change Sagittal Spinopelvic Alignment?

CONCLUSION: PAO increases pelvic incidence, potentially because of anterior translation of the hip center. There were no changes in other spinopelvic parameters postoperatively except after bilateral PAO. Additionally, patients lacking spine mobility preoperatively, indicated by a minimal change in lumbar lordosis between standing and sitting positions, may experience several changes in spinopelvic alignment, including increased mobility of their spine after PAO. This may be because of decreased compensatory spine splinting after increasing acetabular coverage, but further research including patient-reported outcomes is warranted.LEVEL OF EVIDENCE: Level III, therapeutic study.PMID:38564796 | DOI:10.1097/CORR.0000000000003031
