Fractures of neck of femur have always presented great challenges to orthopaedicians and remains in many ways today “The Unsolved Fracture”, as was called many years ago by Dickson and Nicoll as far as treatment and results are concerned. A prospective observational study was conducted between September 2012 to August 2014 in which a sample size of 43 patients were included having an isolated fracture of the neck of femur. All patients underwent a cemented bipolar hemireplacement arthroplasty by either Moore’s or Hardinge’s approach. Patients were followed up monthly for first 3 months and then at 6 months and 12 months. Minimum follow up of 12 months and modified Harris Hip Score was noted and radiographs of the affected hips were taken. Statistical test used was Chi Square test. Out of the 43 patients, there was 1 mortality and 4 were lost to follow up before 1 year duration period. The clinical and radiological outcome of 38 patients were assessed 1 year post-surgery. In this study, the finding of a correlation between Age and Outcome after surgery was seen to be significant. Number of excellent outcomes in patients below the age of 70 was found to be significant [p=.047]. Surgical approach using the Hardinge’s approach had slightly better outcomes in terms of Modified Harris Hip Scores during post-op rehabilitation and at 1 year follow up but was not significant [p=0.767].
