Acetabulum of pelvis11/17/2023 ![]() ![]() A more complete oncologic resection, superior reconstruction, and quicker rehabilitation for affected individuals can result in approximately one half of individuals. Tumor resection and pelvic-periacetabular reconstruction can satisfactorily be performed through extensile pelvic approaches without necessarily performing a hip arthroplasty. acetabulum: cup-shaped depression in the mid-outer pelvis known as the hip this is the socket of the ball-and-socket joint of the hip. The head of femur is hemispherical, and fits completely into the concavity of the acetabulum. Its cavity is deepened by the presence of a fibrocartilaginous collar the acetabular labrum. Gross anatomy All three bones of the pelvis (the ilium, ischium, and pubis) together form the acetabulum. A properly aligned AP pelvis view is imperative in the assessment of early hip degeneration, in particular for the assessment of femoroacetabular impingement. The acetabulum is a cup-like depression located on the inferolateral aspect of the pelvis. The acetabulum (plural: acetabula) is the large cup-shaped cavity on the anterolateral aspect of the pelvis that articulates with the femoral head to form the hip joint. iliopectineal line, ilioischial line, Shenton line) in the trauma setting, as well as, bone lesions and degenerative diseases. These concepts have been incorporated into a new classification system and treatment strategy which is critically examined in 13 individuals. It helps to assess joint dislocations and fractures (i.e. ![]() The additional use of reinforced polymethylmethacrylate and subchondral bone cement augments fixation. Resection of tumor-infiltrated acetabular columns creates reconstructive challenges best met by the techniques and knowledge gained from trauma surgeons repairing acetabular fractures. A new concept for surgically managing periacetabular fractures due to metastases is introduced whose premise is based on pelvic rather than hip pathology. As improving medical management of metastatic cancer increases longevity, improved methods for surgical management of pathologic fractures are required. Previous reports and ideas addressing surgical reconstruction have focused on which type of total hip arthroplasty best suits the acetabular bone stock remaining following removal of the tumor. No advances in surgical reconstruction have been reported in one and a half decades. Your femoral head, which is the upper end of your femur (thigh bone), forms the ball. Your acetabulum, which is part of your pelvis, forms the socket. Management has for the most part remained nonoperative because the complexities of pelvic anatomy and reconstruction yield risks which have outweighed potential benefits. Overview What is an acetabular fracture An acetabular fracture is a break in your hip socket. ![]() Pathologic fracture of the pelvis and acetabulum secondary to metastases is a disabling condition for cancer patients. ![]()
