AbstractAim: The Purpose of this study is to assess the Radiological outcome of Total Hip Arthroplasty in Displaced fracture Neck of femur.
Methods: This prospective observational study was carried out in the Department of Orthopedics, Patna Medical College and Hospital, Patna, Bihar, India, for 1 year. Total 110 patients were treated with total hip replacement. Radiographic evaluation includes Loosening of the acetabulum and femoral components, Inclination of Acetabular cup, Stem position of femoral component, Vertical subsidence, Migration of the Acetabular cup and Heterotopic Ossification. Modified Harris hip score was used for clinical and functional evaluation of patients. Plain X‐ray pelvis with both hips and proximal femur—AP view and X‐ray of the operated hip lateral view for radiological evaluation.
Results: Out of 110, 81 patients were male and 29 female, most of the patients were above 50 year and followed by 4-5 year. Patients scored 53.64% excellent, 27.27 good, 8.19% fair and 10% patients scored poor. The normal acetabular cup inclination is 30o to 45o. In our study 80% neutral, 10.91% vertical and 9.09% horizontal position were seen. The ideal position of stem of femoral component is central. In this study we had 79.09% central, 12.73% in valgus and 8.18% varus position. Varus position of the stem may lead to complications such as anterior thigh pain and periprosthetic fractures. There were 3.64% subsidence and 2.73% migration seen and Class II heterotopic ossification was noted in 6 hip, i.e., 5.45 % incidence who underwent THA. Out of 110, 6 patient with class II heterotrophic ossification seen. We had 4 case of dislocation (3.64%). The dislocation occurred during the 2nd month of the surgery at home
Conclusion: The total hip arthroplasty gave better results in displaced Intracapsular neck of femur fractures radiologically.
