Osteonecrosis is a disease which ultimately results in the destruction of the joint if left untreated. It can affect any joint but occurs most frequently in the hip. There is no agreement as to what causes osteonecrosis, although a number of factors which contribute to the disease have been identified.
Different treatment options are available depending on how far along the disease has progressed. Advanced stages require a total hip replacement. However, if the disease is detected early enough, other alternatives are available. One of these alternatives is a procedure called a core decompression.
This procedure involves drilling a small hole in the diseased bone. One of the features of a core decompression is that it does not limit further surgical treatment should the disease progress. It is a relatively simple procedure and recovery from it is fairly quick. Pain relief occurs rapidly.
