Avascular necrosis of the femoral head is an increasingly common cause of musculoskeletal disability, and it poses a major diagnostic and therapeutic challenge. The aim of diagnostic imaging procedures in avascular femoral head necrosis is to provide the patient with a stage-adapted therapy. The aim of this paper is to present the age incidence and symmetricity of involvement of the non-traumatic avascular necrosis of femoral head. MATERIALS AND METHODS: This is a prospective observational study done during January 2013 to June 2013.The study included a total 30 patients referred to the Department of Radiology, Kurnool medical college, Kurnool, for X ray pelvis with both hips. 10 patients out of them were further investigated with MRI pelvis. RESULTS: More than half of the patients (72.6 %) were within the age groups 30-50 years with male to female ratio of about 4:1. 60% of patients showed bilateral involvement, 20 % showed right femoral head and 20 % showed left femoral head involvement. CONCLUSION: We conclude that disease affects mostly adults within their 3rd and 5th decade and majority of the patients are being men with bilateral involvement. Our study results are comparable with previous studies. Hence we recommend MRI both hips for early identification of AVN changes in asymptomatic contra-lateral hip or normal appearing hip on X-Ray.
