Background: The femoral neck fractures increased with the older age. Surgery considered the main treatment for femoral neck fractures displacement. There is no evidence for the treatment of displaced fractures of the neck of the femur which give the best clinical and functional results. Aim of the study: The aim of the work was to assess the functional outcome and quality of life in terms of pain, mobility, stability using Harris Hip Score in patients with femoral neck fracture, treated with bipolar hemiarthroplasty. Patients & Methods: The current prospective study was carried in the Department of Orthopedics at Faculty of Medicine, Zagazig University during the period from June 2018 to April 2019. The study included 18 patients over 50 years with intra-capsular fracture neck of femur and the fracture treated by hemiarthroplasty using Bipolar endoprosthesis. Results: the study group had excellent outcome according to Harris hip score, had good outcomes. Patients didn't have pain, (27.8%) had slight pain and (5.5%) had moderate pain. This study showed that (50.0%) of the study group didn't have limping, (38.9%) had slight limping and (11.1%) had moderate limping and (50.0%) of the study group didn't need support. Conclusions: Cemented bipolar hemiarthroplasty for fracture neck of femur is a good option in elderly patients. Mobilization and early functional results are good to satisfactory. With this procedure the complication rate is very low and pre injury functional status is restored in majority of patients.
