국문 초록

This study aimed to delineate the macroscopic and microscopic topography of muscles surrounding the anterioraspect of the hip joint and the underlaying joint capsule. Seven fresh-frozen cadavers were bilaterally dissected as perstudy protocol. Eleven hip joints were evaluated macroscopically, while three hip joints underwent histological analysis. Additionally, twenty hip bones and femurs were examined for the osseous morphology near the anterior portion of thearticulating surfaces. Macroscopically, the rectus femoris muscle contributed to the articular capsule exclusively throughits reflected head. The iliocapsularis and iliopsoas muscles were in direct contact with the articular capsule. Although theiliocapsularis muscle was adherent to the capsule throughout its whole course, the iliopsoas muscle was connected to thecapsule through the iliopectineal bursa. Microscopically, different spatial thickness of the capsule was observed, with thethicker regions corresponding to the capsular ligaments. Osseous landmarks, relevant to the course of the iliopsoas muscle,included the iliopsoas notch and a groove for the psoas major muscle. Furthermore, split of the anterior inferior iliac spineand the “subspine” were constant findings corresponding to the origin of the direct head of the rectus femoris and theiliocapsularis muscles, and attachment of the medial band of the iliofemoral ligament, respectively. On the head of thefemur, the Poirier’s facet (35.0%), the Allen’s fossa (60.0%), and the so-called plaque (50.0%) were observed. Conclusively, weintroduce the concept of a four-layered anterior musculocapsular complex of the hip, aiming to aid the orthopaedic surgeonin both hip replacement and preservation procedures.
