2024年11月21日 · Hip osteoarthritis is a degenerative disease of the hip joint that progresses in four characteristic stages. With each stage of osteoarthritis of the hip, symptoms such as pain, stiffness, and loss of joint mobility will progressively worsen.

2009年7月10日 · KEYSTONE, Colo. – Radiographic assessment of femoroacetabular impingement (FAI) uses a host of signs for diagnosis; however, researchers presenting a study here revealed that acetabular...

2020年8月22日 · grade 1: possible joint space narrowing and subtle osteophytes; grade 2: definite joint space narrowing, defined osteophytes and some sclerosis, especially in the acetabular region; grade 3: marked joint space narrowing, small osteophytes, some sclerosis and cyst formation and deformity of femoral head and acetabulum

2022年1月19日 · In our daily work, we found that many patients had acetabular rim osteophytes (ARO), which may lead to recurrent or secondary pincer-type deformity after primary hip arthroscopy for FAI and postoperative ARO sometimes even led to revision surgery.

The femoral head, covered with cartilage, serves as the "ball" of the hip joint, while the acetabulum, deepened by the cartilage rim and labrum, functions as the "socket." Under normal conditions, there is perfect alignment during all types of hip movements. ... Acetabular Retroversion The normal acetabulum has an anteverted orientation (figure ...

2024年12月27日 · To investigate the relationship between SP and LT of the femoral head and osteophyte growth in DDH, we aimed to answer the following questions: (1) What are the most common areas for the growth of acetabular osteophytes? (2) What is the effect of SP or LT on Acetabular osteophytes?

2024年6月13日 · Osteoarthritis is the progressive loss of cartilage between joints, which exposes the underlying bone (subchondral bone). This breakdown (degeneration) affects the normal process of bone remodeling during which bone is continually broken down and rebuilt to keep it …

2021年3月13日 · Acetabular rim ossifications are highly prevalent in asymptomatic, non-osteoarthritic adult hips at all ages. Their size is not correlated with any patient- or hip-related parameters except for age.

2024年1月10日 · A causative mechanism for rim fractures has been proposed, whereby the aspherical femoral head exerts torque while attempting to move in the acetabulum as it encounters a relatively rigid acetabular rim that has limited capacity to expand.

2021年6月23日 · When seen in symptomatic patients, the question is whether to remove them or to fixate the loose fragment to the acetabular rim. This depends on acetabular coverage and the extent of the Os. If removal of the Os might lead to hip dysplasia and instability, fixation of the Os should be the goal.
