Osteonecrosis is a serious disorder in which the bone literally dies due to an insufficient blood supply. The disorder attacks the bone, killing cells in the bone and bone marrow until the diseased section finally collapses. There are several causes of osteonecrosis. Often an injury to the bone that may damage arteries supplying blood or a blocked blood vessel may cause the disease. Over 20,000 new cases are diagnosed in the United States every year.
Symptoms of osteonecrosis include, but may not be limited to, joint pain and stiffness, limited motion and spasms. If left untreated, complete bone collapse requiring surgery may occur.
Osteonecrosis of the jaw has been linked to the use of the osteoporosis drug Fosamax
. You may need to speak with an attorney if you developed the disorder while taking Fosamax.
