What are the two types of femoroacetabular impingement?
There are three types of FAI: pincer, cam, and combined impingement.
What is the most common type of femoroacetabular impingement?
As the most common form of FAI, cam impingement occurs when a bone spur on the ball-shaped end of the femur head leaves it misshapen. When the femoral head isn’t perfectly round, it collides with the acetabulum and can’t move smoothly within the socket.
What is a femoral cam deformity?
Cam deformity is an abnormal bony prominence or “bump” at the junction of the femoral head and neck resulting in an aspherical-shaped head, occurring most commonly along the anterosuperior femoral head-neck area.
What causes cam-type FAI?
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.
What is Cam-type impingement?
Cam impingement occurs because the ball-shaped end of the femur (femoral head) is not perfectly round. This interferes with the femoral head’s ability to move smoothly within the hip socket. Pincer impingement involves excessive coverage of the femoral head by the acetabulum.
What is cam-type morphology?
Cam-type morphology occurs when an abnormally shaped femoral head/neck has a region of increased radius forming a bump or ridge (1). During motions of flexion and internal rotation, an increased amount of shear stress is placed on the labral cartilage by the abnormal contact with the enlarged femoral head/neck (2).

How do you treat cam impingement?
Often, surgery for hip impingement can be performed arthroscopically….Hip Impingement Treatments
- Resting the affected hip.
- Modifying your activities to avoid moving the joint in a way that causes pain.
- Exercising as recommended by your doctor or physical therapist to strengthen the muscles that support the hip.
What causes cam hip impingement?
Cam impingement occurs when the femoral head is not perfectly round and cannot rotate smoothly inside the acetabulum. It often results from a bump formed from excess bone growth at the end of the femur. During movement, the bump grinds the cartilage inside the acetabulum.
What is cam hip impingement?
A cam impingement occurs when excessive bone grows at the edge of the femoral head, where it meets a part of the femur called the femoral neck. The excessive bone growth forms a bump, which can do one or both of the following: Prevent the femoral head from fully rotating in its socket.
What is femoral Cam morphology?
Cam morphology refers to an abnormal morphology of the femoral head-neck junction interlinked with an osseous asphericity. It is one possible causes for femoroacetabular impingement. It is one possible causes for femoroacetabular impingement.
What is a hip Cam?
The Crossover sign: The Alpha angle: measures cam impingement and lack of roundness of the femoral head. Coxa Profunda: measures how deep the femoral head sits inside the acetabulum.
What is a cam hip?
Cam Hip Impingement. Cam femoroacetabular impingement (FAI) occurs when the head of the femur alters the movement in the joint. Specifically, a less spherical femoral head alters the contact area within the joint (at the acetabulum). However, not everyone with a cam morphology exhibits pain or pathology.
