Acetabular retroversion and cam morphology are contributing risk factors for posterior hip dislocation independent of the trauma mechanism

CONCLUSION: Acetabular retroversion contributes to posterior hip dislocation in high-energy and sports-related trauma mechanisms and decreases the likelihood of sustaining concomitant fractures. Acetabular morphology was subordinate to causing hip dislocation following a low-energy impact. Increased alpha angles were identified as a risk factor contributing to posterior hip dislocations, regardless of the trauma …
