Radiological outcome of total hip arthroplasty in displaced fracture neck of femur

Abstract

Aim: to assess the Radiological outcome of Total Hip Arthroplasty in Displaced fracture Neck of femur. Materials and Methods: This prospective observational study was carried out in the Department of Orthopaedics at Shri Krishna Medical College and Hospital Muzaffarpur, Bihar, India from December 2017 to March 2019. Total 100 patients were patients 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 100, 75 patients were male and 25 female, most of the patients in were above 50 year and followed by 40-50 year. Patients scored 48% excellent, 28% good, 10% fair and 14% patients scored poor. The acetabular cup inclination   80 neutral, 12 vertical and 8 horizontal positions were seen. We had 78 central, 12 each in valgus and 10 varus position. There were 2 subsidences and 1 migration seen and Class II heterotopic ossification was noted in 6 hips, i.e., 6 % incidence that underwent THA. We had 3 case of dislocation (3%). The dislocation occurred during the 2^nd month of the surgery at home.Conclusion: The results of this study shows that Total Hip Arthroplasty gave better results in Displaced Intracapsular Neck of femur fractures radiologically.
