Osteonecrosis & Femoroacetabular Syndrome
Osteonecrosis [5] of the hip joint occurs when blood flow is affected or blocked in the bones that form the hip joint and they do not receive enough blood supply and nutrients. The cells of these bones begin to die off due to this blood supply cut off. The most common factors that can cause osteonecrosis are:
-
serious injury that results in impaired blood supply to the bone;
-
prolonged or excessive use of corticosteroids;
-
Excessive alcohol consumption.
However, sometimes the causes of osteonecrosis can be unknown. Bone necrosis causes pain and restraints in the affected joint. If osteonecrosis is detected in a timely manner and affects small areas of the bone, pain relievers and less stress (including walking) can give good results. With the development of the disease, surgical intervention is required. To treat osteonecrosis, operations of various types and degrees of complexity are used, up to a total replacement of the hip joint – endoprosthetics or arthroplasty.
Femoroacetabular syndrome happens when there are bone processes [6] (osteophytes) on the bones forming the hip joint. Recoil syndrome, limitation of movement in the joint, and pain gradually develop. The cause of the disease can be a joint injury. This disease sometimes causes osteoarthritis. Sharp (sometimes dull) pain occurs when a person turns and crouches. Osteophytes can be removed surgically, but over time they form again, damaging the joint.
