My mother had a surgery of broken femur neck on April 1, 2017, where 3 screws were used to join the bones.Since then she is suffering pain in that particular leg and in the last visit our doctor suggested for a CT scan to analyse that problem. And after viewing the reports he suggested that we have to go for a total hip replacement surgery, and a few important points of the report are, "Mild sclerosis and minimal joint effusion but r/o early AVN". Please suggest any alternative opt for treatment
