Core decopression and iliac crest cancellous bone autografting in treatement of
avascular necrosis of the femoral head : a retrospective and continued study of 66 cases.
The goal of this study is to evaluate the effectiveness of core decompression and iliac
crest cancellous bone autografting as preserving treatement of osteonecrosis of the femoral
head. At 2 years following grafting, results are 58% of successes in global study with an
overall survivorship of 29 months. One in addition notices a clear difference according to the
stage with 64% of succes for the ARCO stage II (70% for stage IIA and IIB ) and only 45% for
stage III. Two years after treatement, half of the initial radiological lesions remained stable and
the follow-up shows a good perpetuation of the results beyond this period.
It seems to bee a good indication for ARCO stage IIA/IIB. In the event of failure, this
technic does not disturb the installation of a prothesis or resurfacing.
In addition the role of tobacco has a long time been underestimated by authors in
ethiopathology of this desease. If the high proportion smokers in our serie does not certainly
make possible to conclude at the imputability of tobacco, one cannot exlude it for as much.
