Bill, a 34 year old male, arrived at the doctor’s office experiencing pain in his right hip. Prior to this, Bill maintains an overall healthy lifestyle which includes exercising and activities such as; swimming, water skiing and scuba diving. Bill reports he has had no trauma to his hip. On this visit an analgesic and muscle relaxant were both prescribed to the patient and he was sent home. After three weeks of no improvement Bill has returned to the doctor’s office and has reported increasing pain and stiffness in not only the right hip, but the left hip as well. Blood has been drawn and sent to the lab for testing and he has also been sent to the radiology department for x-rays.
BACKGROUND OF AVASCULAR NECROSIS

While scuba diving Bill suffered from the “bends” or decompression sickness. (Bove) When diving there is a lot more pressure than on land and nitrogen molecules can accumulate in the blood and tissues. (Bove) When the molecules accumulate they can expand causing injury and blockage of blood supply. (Bove) This is a very valid explanation of Bill’s case of avascular necrosis. Avascular necrosis is caused from a loss of blood supply to the bone and decompression sickness can cause blockage of the blood supply. Bill did not notice any symptoms until about seven months after the event occurred. This is because the bone is slowly broke down and it does not get noticed until enough damage is done because of the pain experienced. It is very likely that he has other parts of his body affected that he does not know about yet. In only three weeks his symptoms went from the left hip to both the left and right hip. Bill may regain movement of his hip eventually. It all depends on how affected the area is. Some non-surgical possible treatments include; medications, reduced weight bearing, range of motion exercises and electrical stimulation. "Osteonecrosis." Sometimes an anti-inflammatory and a blood thinner can reduce pain and reduce the blood clots blocking the blood supply. "Osteonecrosis." If diagnosed early, reducing the amount of weight on the joint can prevent further damage. "Osteonecrosis." By practicing range of motion exercises, it keeps the joint functioning and mobile and in some cases electrical stimulation can induce bone growth. "Osteonecrosis." Some surgical options are; core decompression, osteotomy, bone graft or a joint replacement. "Osteonecrosis." In a core decompression operation the surgeon removes the inner cylinder of the bone to reduce the pressure. "Osteonecrosis." An osteotomy is a little similar to a core decompression, rather than removing the core the
