2022年1月26日 · Os acetabuli (plural: ossa acetabuli) are small ossicles adjacent to the acetabular roof regions and may represent an unfused secondary ossification center of the acetabulum or pathological sequelae (e.g. acetabular rim …

2021年6月23日 · Os acetabuli (Os) or acetabular rimfractures are often seen in femoroacetabular impingement patients and can result in groin pain. When seen in symptomatic patients, the question is whether to remove them or to fixate the loose fragment to the acetabular rim.

2024年1月10日 · True os acetabuli was defined as an unfused secondary ossification centre along the acetabular rim. The aetiology of os acetabuli is thought to be secondary to acetabular dysplasia and/or femoroacetabular impingement.

2025年1月6日 · What is the acetabulum? The acetabulum is a large socket on the lateral face of the hip bone that articulates with the head of the femur to form the hip joint. Anatomically, the acetabulum is formed by the fusion of the three pelvic bones: the ilium, ischium, and pubis.

Acetabular rim fractures, or os acetabuli, are an intra-articular condition characterized by formation and separation of an osseous fragment originating from the anterolateral acetabular rim.

2023年1月5日 · Periacetabular rim ossifications were classified into 4 types based on radiographic appearance: (1) partial labral ossifications or punctate calcifications, noted by a small radiodense nucleus adjacent to the lateral edge of the acetabular sourcil 1, 3, 9; (2) true os acetabuli, indicated by large size, rounded shape, and oblique or horizontal ...

However, in 2–3% of asymptomatic patients, an accessory ossification center may persist as an ossicle that is known as an os acetabulum and is typically located along the acetabular rim [8] (Fig. 2). Os acetabuli are unfused to the acetabulum and are …

The acetabulum (/ ˌæsɪˈtæbjələm /; [1] pl.: acetabula), also called the cotyloid cavity, is a concave surface of the pelvis. The head of the femur meets with the pelvis at the acetabulum, forming the hip joint. [2][3] There are three bones of the os coxae (hip …

2022年8月2日 · Perhaps more than any other hip pathology, the os acetabuli exists at the intersection of dysplasia and impingement. Studies have consistently identified os acetabuli in patients both with and without FAI.

In this first part we look at the ossifications you can see around the acetabular rim, their importance and how to differentiate them on a plain xray. What do you call the areas of ossification or calcification you see adjacent to the labrum and are they significant or just developmental variants? This has caused me so much confusion.
