Clinical and functional outcome of total hip arthroplasty in failed proximal femoral fracture osteosynthesis

Abstract

Introduction: The use of internal fixation for hip fractures can fail secondary to nonunion, loss of fixation, femoral head osteonecrosis, posttraumatic arthritis, malunion, infection, or symptomatic hardware. Conversion of failed hip surgeries to THA is indicated where the bone quality is poor, head is damaged due to previous internal fixation, poor bone stock, or limb shortening Methodology: Detailed history and proper clinical examination was done to find out – duration of illness, focus of infection in the body, sensory and motor examination, vascularity of the limb, ambulatory status of the patient, deformities of the hip, Range of Movements (ROM) of the hip, limb length discrepancy and status of the other joints Results: The average pre-operative Harris Hip Score was 36.28 and the Harris Hip Score at most recent follow-up was 83.19. The result was excellent in 8 patients, Good in 6 patients, fair in 5 patients and poor in 2 patients Conclusion: Uncemented total hip arthroplasty is the procedure of choice for the patients with failed proximal femoral osteosynthesis providing pain relief, preservation of mobility, range of motion and easy rehabilitation
