What causes bilateral mixed femoroacetabular hip impingement? what is gluteus medius tendinopathy is that a tear in the medius?

Hip impingement is: a condition in which extra bone grows along one or both of the bones that form the hip joint, causing the joint space to be compromised. This is often caused by mild trauma from overuse or repetitive flexion at the hip. Tendinopathy is inflammation of the tendon that attaches a muscle to the bone and can be from overuse, acute trauma, or impingement. It is not a tear of the muscle itself.
