What does coxa profunda mean?
deep acetabular socket
Coxa profunda refers to a deep acetabular socket. Acetabular protrusion is intrapelvic displacement of the acetabulum and femoral head, so that the femoral head projects medial to the ischioilial line.
What causes coxa profunda?
The arthritic process is initiated by the damage to the labrum and acetabular rim cartilage caused by femoral neck impaction as well as from contre coup cartilage damage that occurs when the neck levers against the rim.
Is coxa profunda a hip impingement?
Coxa profunda, or a deep acetabular socket, is often used to diagnose pincer femoroacetabular impingement (FAI). Radiographically, coxa profunda is the finding of an acetabular fossa medial to the ilioischial line.
Why is it called Cam impingement?
The first involves an excess of bone along the upper surface of the femoral head, known as a cam deformity (abbreviation for camshaft, which the shape of the femoral head and neck resembles). The second is due to an excess of growth of the upper lip of the acetabular cup and is known as a ‘pincer’ deformity.
How common is coxa profunda?
Coxa profunda was found in 76% of asymptomatic hips and 64% of hips with FAI. In the study, 70% of women had coxa profunda compared to 24% of men. Researchers noted acetabular over coverage in 22% of hips with coxa profunda.
How serious is hip impingement?
Over time, hip impingement symptoms can get worse. The labrum or the protective cartilage can incur damage, which can lead to arthritis. For this reason, hip impingement is considered a pre-arthritic condition as it accelerates the breakdown of cartilage, which is a hallmark feature of arthritis.
Are you born with hip impingement?
The condition may begin at birth (congenital) or may develop as a child grows (acquired). The condition appears to be caused by a combination of genetic and environmental factors.
What causes a hip impingement?
Hip impingement may be caused by a misshapen femoral head, deformed femoral neck, or a hip socket that covers too much of the femoral head. Over time, repetitive “bumping” or impingement of the femur on the rim of the acetabulum leads to cartilage and labral damage.
What happens if you don’t treat hip impingement?
Hip impingement also may damage the protective cartilage that covers the ends of the bones in the joint, called articular cartilage. That can wear down the cartilage over time and eventually make it deteriorate completely — a condition known as hip osteoarthritis.
