Management of avascular necrosis of femoral head by core decompression
Keywords:Femoral head, AVN, Core decompression
Background: Avascular necrosis (AVN) is defined as cellular death of bone components due to interruption of the blood supply; the bone structures then collapse, resulting in bone destruction, pain, and loss of joint function. The head of femur is the most common bone affected by avascular necrosis. Our aim is to study results of core decompression and bone grafting in avascular necrosis of femoral head.
Methods: The present study was performed at Pravara Rural Hospital, a constituent hospital of Rural Medical Collage at Village Loni, Rahta and district: Ahamadnagar. The study includes patients who underwent core decompression and bone grafting in avascular necrosis of femoral head at Department of Orthopaedics, Pravara Rural Hospital from June 2015 to June 2017.
Results: In our study majority of the patients belongs to the group of 31-40 years and most of them were males. Male female ratio was 4:1. Out of 20 patients, 6 of them were unilaterally involved rest 14 had bilateral involvement. Out of 28 hips of bilateral involvement 6 were grade III and IV Ficat and Arlet. That 6 were not considered as they come in grade III & IV of FICAT & ARLET classification. So we study 28 hips only.
Conclusions: The average success rate was 82.61% after core decompression and bone grafting. The patients who had less than 60 Harris hip score on presentation had poorer outcome. Patients who had less than 80 degrees of flexion had also poorer outcome.
