Functional Outcome of Total Hip Arthroplasty in Patient with Flexion Contracture due to Hip Ankylosis: A Rare Case Report

Abstract

BACKGROUND: Performing total hip arthroplasty (THA) or total hip replacement (THR) in hip ankylosis is not a simple procedure. CASE PRESENTATION: We presented a complicated case of a patient with flexion contracture and ankylosis of hip joint due to neglected avascular necrosis of femoral head treated with THR on one thigh, and periprosthetic fracture on the other which was also treated with THR later. One year after the surgery, the both hips function was improved and the patient was able to walk without assistive device. CONCLUSION: Total hip replacement is a modality that could be considered for the treatment of advanced AVNFH and ankylosis of hip joint, with femoral periprosthetic fracture as one of its potential complications.
