What is a coxa profunda 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 is coxa profunda in pincer femoroacetabular impingement?
Background: 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. However, the relative position of the acetabular fossa to the pelvis may not be indicative of acetabular coverage.
How common is coxa profunda in the US?
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.
Is coxa profunda a common radiographic finding in football players?
Coxa profunda existed in hips representing the spectrum of acetabular coverage measured by LCE angle (-18° to 60°) and acetabular orientation determined by the crossover sign. Conclusions: Coxa profunda was a common radiographic finding in both symptomatic patients and asymptomatic football players.
How do you treat coxa profunda?
We recommend that the majority of cases be treated with surgical hip dislocation. Trimming of the entire acetabular rim during open surgical dislocation will reduce the depth of the acetabulum, and, when appropriate, labral refixation and, if absent, labral reconstruction using a graft can be performed.
What is coxa profunda hip?
Background: 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.
How common is coxa profunda?
Results: Coxa profunda was seen in 55% of the 157 hips and was slightly less common in the hips with acetabular dysplasia or residual Legg-Calvé-Perthes deformities (41% and 31%, respectively).
Do you need surgery for hip impingement?
If hip impingement syndrome causes significant pain and symptoms don't improve with nonsurgical treatment or therapeutic injections, our orthopedic surgeons may recommend surgery. They can reshape the bones in the hip joint, so that the round femoral head can rotate smoothly within the socket-shaped acetabulum.
What is acetabular profunda?
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.
What causes a hip impingement?
It is caused when the femoral head (the ball-shaped bone at the top of the femur or thigh bone) and the acetabulum (the socket in the pelvis into which the femoral head fits) don't fit together properly. This is often the result of extra bone in the hip, though it can also be caused by bone deformity.
What is acetabulum in the hip?
What is an acetabulum? The hip is one of the body's largest joints. It is a "ball-and-socket" joint. The socket is formed by the acetabulum, which is part of the pelvis. The ball is the femoral head, which is the upper end of the femur (thighbone).
How does a surgeon dislocate a hip?
How does surgical hip dislocation work? During the procedure, to gain access to the hip joint, the surgeon separates and retracts a piece of bone from the greater trochanter (the upper part of the femur), which is the attachment site for important muscles that completely surround the hip and facilitate its movement.
What is hip dysplasia?
What Is Hip Dysplasia ? Hip dysplasia is a condition that is seen more often in women and occurs when the acetabulum (the socket in the pelvis into which the femoral head fits) is too shallow to support the femoral head (the ball-shaped bone at the top of the femur or thigh bone).
Can a cortisone shot help hip impingement?
For some people, a corticosteroid injection provides pain relief that lasts for many months; in others, the injection isn't effective. Most people experience some pain relief, lasting for a few weeks or months. Doctors recommend no more than a total of two or three corticosteroid injections in the hip joint.
What aggravates hip impingement?
Patients with hip impingement often report anterolateral hip pain. Common aggravating activities include prolonged sitting, leaning forward, getting in or out of a car, and pivoting in sports. The use of flexion, adduction, and internal rotation of the supine hip typically reproduces the pain.
How serious is hip impingement?
When the labrum is torn, it can cause hip pain. 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.
What is acetabulum in the hip?
What is an acetabulum? The hip is one of the body's largest joints. It is a "ball-and-socket" joint. The socket is formed by the acetabulum, which is part of the pelvis. The ball is the femoral head, which is the upper end of the femur (thighbone).

What is COXA Vara?
Coxa vara is an unusual hip condition in which there is a discrepancy of growth in the round ball of the hip (femoral head) and the upper end of the thigh bone. This discrepancy leads to a shepherd's crook deformity of the hip.
What is hip dysplasia?
What Is Hip Dysplasia ? Hip dysplasia is a condition that is seen more often in women and occurs when the acetabulum (the socket in the pelvis into which the femoral head fits) is too shallow to support the femoral head (the ball-shaped bone at the top of the femur or thigh bone).
What is the Coxa profunda?
Coxa profunda. Coxa profunda refers to a deep acetabular socket. On pelvis x-rays it is seen as the acetabular fossa being medial to the ilioischial line. It should be differentiated from protrusio acetabuli, where the femoral head is seen additionally medial to the ilioischial (Kohler's) line. Coxa profunda is much more common in females.
Is Coxa profunda a specific finding?
Coxa profunda is a non-specific finding and has previously been implicated in pincer-type femoroacetabular impingement, but is just as likely to be seen in asymptomatic patients 1,2.
Is Coxa profunda more common in females?
It should be differentiated from protrusio acetabuli, where the femoral head is seen additionally medial to the ilioischial (Kohler's) line. Coxa profunda is much more common in females.
What is the coxa profunda?
Radiographically, coxa profunda is the finding of an acetabular fossa medial to the ilioischial line. However, the relative position of the acetabular fossa to the pelvis may not be indicative of acetabular coverage.
Is Coxa profunda a symptomatic or asymptomatic?
Conclusions: Coxa profunda was a common radiographic finding in both symptomatic patients and asymptomatic football players. Coxa profunda existed in hips representing the spectrum of acetabular coverage and was not associated with an overcovered acetabulum. We conclude coxa profunda is unrelated to overcoverage and suggest its use in diagnosis of pincer FAI be abandoned in favor of other determinants of focal or general overcoverage.
Is Coxa profunda a radiographic parameter?
Coxa profunda is not a useful radiographic parameter for diagnosing pincer-type femoroacetabular impingement
Is Coxa profunda a diagnosis?
Coxa profunda should be considered a normal radiographic finding, at least in females. Coxa profunda is a nonspecific radiographic finding, seen in a variety of hip disorders and asymptomatic hips. The presence of coxa profunda is neither necessary nor sufficient to support a diagnosis of pincer-typ …
What is the disease in which the ball part of the hip joint doesn't get enough blood?
Legg-Calve-Perthes disease, a disease in which the ball part of the hip joint doesn't get enough blood, which causes the bone to die.
What is a slipped capital femoral epiphysis?
Slipped capital femoral epiphysis, a separation of the ball from the thigh bone at the upper growing end (growth plate) of the bone in adolescents. It is more common in children who are obese. Coxa vara, an unusual condition in which the thigh bone and ball do not grow at the same pace in children. This discrepancy leads to deformity ...
What is the test that shows irregularities in the shape of the ball or top of the thigh bone?
X-ray, a test that produces images of internal structures on film. X-rays can show irregularities in the shape of the ball or top of the thigh bone or excess bone around the rim of the socket.
What is the term for a bump in the thigh bone?
A deformity of the socket (pincer impingement). If the front rim of the socket (called the acetabulum) sticks out too far, the area of the thigh bone (femur) just below the ball, called the neck of the femur, may bump into the rim of the socket during normal hip flexion movement.
