Pain relief with core decompression and autologous bone graft in osteonecrosis of femoral head in grade 2

Abstract

Background: Osteonecrosis of femoral head means death of osteocytes with subsequent structural changes leading to femoral head collapse and secondary osteoarthritis of hip joint. Avascular term is reserved for osteonecrosis due to interruption of nutrient arteries as result of fracture of femoral neck and dislocation of hip joint. The most common presenting symptom in osteonecrosis is pain in hip joint. The aim of this study is to evaluate pain relief in early stage of osteonecrosis in patients operated with core decompression with bone grafting at different stage of follow up.Material and Method: In prospective study, we included 50 hips of stage 2 based on Modified Ficat and Arlet classification. We did core decompression with 8mm diameter track and filled with cancellous bone graft taken from posterior superior iliac crest. Pain relief assessed based on visual analogue score at all stage of follow up. Results and Conclusion: According to our study it is found that core de compression with bone grafting provide satisfactory outcome for pain relief if patient is selected carefully with early stage of osteonecrosis before collapse of femoral head. It is method of choice for young patient presented with early changes.
