The functional and surgical relevance of the iliocapsularis muscle: an anatomical review

Abstract

The iliocapsularis muscle covers the anterior aspect of the hip joint capsule. Although its anatomy has been describedthrough cadaveric and radiologic studies, its true function is unknown. The iliocapsularis could be involved in preventinganterior synovial impingement, a possibility supported by electromyography studies. Moreover, hypertrophy of the iliocapsularis caused by hip dysplasia supports the proposal that it stabilizes the anterior aspect of the joint capsule. This review discusses the clinical relevance of the iliocapsularis
