Abstract

CT of the hip was done on 37 patients those who have been suffered from chronic hip joint pain. There were 18patients of avascular necrosis of hip (AVN), 67% of whom were affeted bilaterally, 15 patients of degenerativearthritis (DA), 33% bilaterally; one patient of tuberculous arthritis, rheumatoid arthritis and traumaticarthritis respectively. Comparison of the staging by means of the CT and plain film showed good correlationbetween the two methods. The CT findings of the AVN and OA were also compared; crescent sign or fissure, loss ofcongruity, and loss or change of normal asterisk sign were more commonly seen in AVN. Acetabular change sepeciallyassociated cystic appearance, osteophytes formation and joint narrowing were more frequent in OA. CT showedprimary and secondary change of AVN and OA more clealy without confusion than plain film. We think that CT can behelpful in evaluation and understanding of each disease process and differentiation of the two lesions indifficult cases.
