Aim: Radiological assessment of Total Hip Arthroplasty in Displaced fracture Neck of femur. Materials and Methods: This observational study was carried out in the Department of Orthopaedics Anugrah Narayan Magadh Medical College and Hospital, Gaya, Bihar, India Total 110 patients were patients treated with total hip replacement. Plain X-ray pelvis with both hips and proximal femur-AP view and X-ray of the operated hip lateral view were evaluated. Results: Out of 110, 80 patients were male and 30 female, most of the patients in were above 50 year and followed by 45-50 year. Patients scored 47.3% excellent, 27.3 good, 10.9% fair and 14.5% patients scored poor. The acetabular cup inclination 85 neutral, 15 vertical and 10 horizontal positions were seen. We had 82 central, 15 each in valgus and 13 varus position. There were 2 subsidences and 1 migration seen and Class II heterotopic ossification was noted in 4 hips, i.e., 6 % incidence that underwent THA. We had 2 cases of dislocation (1.8%). Conclusion: The results of this study shows that Total Hip Arthroplasty gave better results in Displaced Intracapsular Neck of femur fractures radiologically
