Why a core decompression?
We have shown, as published in numerous medical journals, that there is an increase in the pressure within the diseased bone. This increase in pressure is associated with pain which in some patients becomes intolerable. Core decompression Adecompresses@ the bone. That is, it relieves the pressure from within this rigid structure. The drill hole then fills with tissue and, in some cases, new bone forms within this area. It may increase the blood flow to the diseased area of bone and allow new blood vessels to form. The procedure appears to slow down the disease process in most cases and may even stop its progression in others. Under the right circumstances, the results of core decompression indicate that it is an effective treatment for osteonecrosis. What are the right circumstances? First, the results are best for treatment of the early stages of the disease. Results after the joint has collapsed are less successful, although in some cases pain relief still occurs. Therefore, it is be
