Background: While the treatment for displaced femoral neck (Garden types I and II) is still the subject of controversy. Aim of Study:The aim of this thesis is to compare the results of internal fixation and bipolar hemiarthroplasty in non-displaced fracture neck of femur in elderly patients. Patients and Methods:The study was performed on 3 patients over 60 years with non-displaced fracture neck of femur, 15 of them treated with internal fixation by cannulated screws, while the other 15 treated by bipolar arthroplasty.Results: All patients were followed up for a mean period of 12 months radiologically by serial X-rays and clinicaly by Harris hip score, where the overall mean Harris Hip score in fixation group was 74, while it was 86.3 for the replacement group.Conclusion: There was a significant relationship between the time of delay of operation and the final outcome in fixation group. There was no significant relationship between the final outcome and age, sex, and garden type of the fracture.
