Introduction: Avascular necrosis of the femoral head is commonly encountered now-a-days with increasing use of steroids and alcohol. MRI is considered the most effective diagnostic investigation for avascular necrosis and is helpful for screening and detecting at early stage.
Aim: The aim of the study was to determine the prevalence pattern and stages of presentation of Avascular Necrosis (AVN) of the femoral head.
Materials and Methods: This was a retrospective study carried out at the Department of Radio-diagnosis in which MRI of the hip joint was performed during our study period, only those patients which showed positive signs for avascular necrosis of femoral head were included and were analysed over a period of seven years. The age, sex, laterally distribution, causative factors, staging according to Ficat and Arlet classification was done.
Results: It was found that most commonly males of productive age group (21 to 40 years) were affected. Most of them had bilateral involvement however the involvement of left and right hip joint was nearly the same. Mostly, patient presented with stage-III disease accounting for 81 patients.
Conclusion: Considering that the young males were commonly affected and presented with advanced stage disease it was recommended that screening MRI should be done in all patients presenting with hip complaints especially males of productive age group.
