What are the most common causes of 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 causes extra bone growth in hip?

It may be caused by repetitive overuse during adolescence, due to chronic growth plate irritation causing abnormal bone growth around the hip. It is the deformity of a cam bone spur, pincer bone spur, or both that leads to joint damage and pain.

What causes pincer hip impingement?

Pincer hip impingement results from an excessive envelopment of the femoral head by the acetabulum, leading to the femoral neck coming into contact with the acetabular rim during movement. Over time, this continuous contact may damage the labrum and surrounding cartilage.

What movements cause hip impingement?

It injures the labrum and articular cartilage, and can lead to osteoarthritis of the hip if left untreated. 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.

Is hip impingement hereditary?

The condition appears to be caused by a combination of genetic and environmental factors. Some researchers believe that the risk of FAI is increased by significant athletic activity before a child’s bones are mature and that contact sports may make hip impingement worse.

What are the two common types of extra-articular hip impingement?

EHI is caused by abnormal contact between the extra-articular regions of the proximal femur and pelvis. This review discusses the most common forms for EHI including: central iliopsoas impingement, subspine impingement, ischiofemoral impingement, and greater trochanteric-pelvic impingement.

What causes cam and pincer lesions?

Very often, the Cam and Pincer forms exist together. The cause of these bony variations is not known at this time. FAI is associated with articular cartilage damage and labral tears and may result in hip arthritis at a younger age than usually occurs.

Is FAI hip hereditary?

FAI is caused by deformities in the femur, hip socket or a combination of both. 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.

Can FAI be caused by trauma?

Femoral acetabular impingement (FAI) is a deformity of the hip joint that limits the hip’s normal range of motion. This condition can be caused by trauma to the hip or repetitive movements, but is most often caused due to bone growth in the femoral head or in the hip joint’s socket.

Can tight hip flexors cause hip impingement?

A hip becomes compressed for a number of reasons. Tightness through the hip flexors or the hip capsule can cause hip compression. It can also occur due to tightness through the ‘short hip external rotators’ (we usually blame the piriformis but there are actually 6 different muscles here that could all be contributing).

Can hip impingement get worse?

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.

Is it common to have intra-articular and extra-articular hip issues at the same time?

Extra-articular hip impingement (EHI) is caused by abnormal contact between the extra-articular regions of the proximal femur and pelvis and may coexist with intra-articular FAI. Regions of abnormal contact may exist between the greater trochanter, lesser trochanter, extracapsular femoral neck and the ilium or ischium.

What is the meaning of extra-articular?

Extra-articular means outside of or other than a joint. RA affects your joints, as well as other systems in your body. Therefore, you can also call these manifestations or effects systemic. RA inflammation affects your joints through swelling, pain, and potentially joint damage.

Is Cam impingement hereditary?

Causes and Risk Factors The condition appears to be caused by a combination of genetic and environmental factors. Some researchers believe that the risk of FAI is increased by significant athletic activity before a child’s bones are mature and that contact sports may make hip impingement worse.

What are the two common types of extra articular hip impingement?

What causes hip impingement?

Trauma from repetitive hip flexion damages the cartilage of the socket, leading to hip impingement or femoro acetabular impingement (FAI). It is believed to be a major cause of early osteoarthritis of the hip, particularly in those under age 40.

What is extra-articular hip impingement?

Extra-articular hip impingement (EHI) is an emerging group of conditions that have been associated with intra-articular causes of impingement and may be an unrecognized source of pain. EHI is caused by abnormal contact between the extra-articular regions of the proximal femur and pelvis.

Why does my hip hurt when I flex it?

Hip impingement also can be caused by a combination of these two problems. Most people with hip impingement experience pain in the groin area during or after flexing the hip, as when running, jumping or sitting for a long time. You may also have difficulty flexing your hip beyond a right angle.

What is the second type of hip impingement?

The second type of impingement occurs when the acetabulum (cup) is abnormally shaped. The cup may cover the head of the femur too much, creating friction when the edge of the cup hits the head/neck of the femur. It is also possible to have a combination of these two types. What are the signs and symptoms of hip impingement?
