Anterior Inferior Iliac Spine Bone Morphology in Hip Dysplasia and Its Effect on Hip Range of Motion in Total Hip Arthroplasty

Our results demonstrated that the AIIS bone morphology substantially affects the ROM of Flex and Int-R especially in patients with laterally large AIIS bony anatomy in THA. Furthermore, our result indicates that the morphologic features of AIIS in hip dysplasia may be different between males and females.
