One of the major reasons for total hip replacement surgery based on statistical data isavascular necrosis -- also known also as hip osteonecrosis http://www.specialoilpainting.com/Animal-c-39.html - abstract painting . In the United States alone,around 20,000 cases are reported every year. This condition accounts for over 10 percent of hip surgeries performed in the country http://quux.me/neo/2005/12/begging-on-the-internet.html#comments - Pablo Picasso oil painting ey . Perhaps the most notable person to be afflicted with this disease and who subsequently achieved greater glory after the hip surgery is sports great Bo Jackson.

Avascular necrosis occurs when blood flow to the hip bone is reduced which results to the death of the bone tissue mainly due to starvation. While this disorder may be present in other parts of the body, it is usually the hips which are greatly affected. Mostly afflicted with this disorder are those considered as younger or middle-aged adults.

A number of factors have been identified as causing this condition. In a survey conducted in Japan, it was found out that 34.7 percent was due to corticosteroid use, 21.8 percent to alcohol abuse, and 37.1% due to various causes which may include blockage in blood vessels from sickle cell anemia or fat particles, hip fracture or dislocation, blood clots http://www.specialoilpainting.com - hand painted oil painting , inflammation of the arteries and other disorders which block the blood flow to the bones.

No symptoms are experienced by the patient in the early stages. As the disease progresses http://www.specialoilpainting.com/City-life-c-56.html - abstract painting , it becomes painful especially when pressure is applied on the affected area. As the condition worsens, the pain in the hip may become more intense and constant. Further deterioration may eventually lead to the collapse of the bones and the nearby joints which may then produce severe and chronic pains and may greatly affect mobility of the affected joints. The period between the appearance of the first symptom to the collapse of the bones and joints may range from a number of months to more than a year.

Treatment for avascular necrosis is geared toward the improvement of function of the affected joint, halt the progress of the bone damage, and the lessening of pain. Factors considered when treating this condition include the age of the patient, stage of the disease, location of damage, and the underlying cause.

If the condition is http://www.specialoilpainting.com - landscape oil painting , for example, due to blood clots, the physician may prescribe medications meant to dissolve the clots. If inflammation of the arteries is the main reason behind the disease, treatment may involve taking of anti-inflammatory medicines. Other forms of treatment may include conservative measures like reduction of weight, physical therapy and behavioral changes. Use of devices such as canes and crutched may also help the patient http://www.hirwaunpool.co.uk/forum/forum_posts.asp?TID=409731&PID=467441#467441 - van gogh oil painting il .


While these measures may reduce the pain or slow the condition, records will show that most of these patients may have to undergo surgery. Surgical options available include bone graft http://www.specialoilpainting.com/ - oil painting abstract , osteotomy, core decompression http://www.genie-records.com/mangoteamclubs/index.php?topic=18852.msg346534#msg346534 - landscape oil painting cl , and total hip replacement surgery.
