How is CAM impingement typically defined?

CAM impingement is typically defined as an aspherical femoral head. In this condition, the femoral head does not have a perfect spherical shape, which can lead to abnormal contact between the femur and the acetabulum during hip motion. This abnormal contact can result in pain, limited range of motion, and potential damage to the cartilage and surrounding structures of the hip joint.

The aspherical shape of the femoral head can create mechanical conflicts during movement, particularly during flexion and internal rotation. Over time, this can lead to a variety of hip-related issues, such as labral tears or osteoarthritis. Recognizing CAM impingement is crucial for appropriate treatment and management of hip pain and dysfunction.

Understanding the specific nature of CAM impingement helps healthcare professionals devise effective therapeutic strategies and interventions aimed at minimizing symptoms and preventing further joint damage.
