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).Click to see full answer. Keeping this in view, what does cam type mean?Cam. In cam impingement the femoral head is not round and cannot rotate smoothly inside the acetabulum. A bump forms on the edge of the femoral head that grinds the cartilage inside the acetabulum. Combined. Combined impingement just means that both the pincer and cam types are present.Furthermore, what does CAM stand for in hip impingement? Introduction. Cam-type femoroacetabular impingement (FAI) is a known cause of groin pain and a condition that can give rise to osteoarthritis of the hip (1). Patients suffering from this condition are mainly young and experience pain when the hip is moved through internal rotation and adduction at 90° of hip flexion. Similarly, you may ask, what is a cam deformity? A deformity of the ball at the top of the femur (called cam impingement). If the head is not shaped normally, the abnormal part of the head can jam in the socket when the hip is bent. This may occur during activities such as riding a bicycle or tying your shoes. A deformity of the socket (pincer impingement).Can hip impingement be fixed?Unfortunately, for many people, surgery for femoroacetabular impingement does not relieve pain as much as expected. Sometimes it makes pain worse. The FAI Fix helps you retrain the muscles that can cause problems so that you can get relief even if surgery for FAI hasn’t helped.
