Polished stem hemiarthroplasty for fracture neck of femur – intra operative techniques- a retrospective analysis of outcome in 100 cases

Introduction: This retrospective study was conducted to know the outcome of polished stem hemiarthroplasty, since hydroxyapatite coated stems are costly and hence cannot be used in economically constrained scenario. Objective: To study the outcome of polished stem hemiarthroplasty which was done in absence of the costly coated stems. Methodology: The study was conducted from March 2014 to 2017.100 patients with fracture neck of femur were included for this study. Patients underwent hemiarthroplasty with polished stem Austin Moore’s Prosthesis (AMP) or standard non-modular bipolar prosthesis or Thompsons Prosthesis. The patients were analyzed at 1 year follow up using Modified Harris Hip Score, Numerical pain rating scale, Face pain scale. Radiographs were also examined for signs of failure. Results: There were 66 females and 34 males. Age ranged from 55 to 90 years. Mean duration of hospitalization was 6 days. Mean number of days from injury to surgery was 3 days. Mean Operative time was 55 minutes. Overall outcome was tabulated as Excellent (38 patients), Good (39 patients), Fair (16 patients) and Poor (4 patient). Conclusion: Polished stem Hemiarthroplasty does give satisfactory results using the techniques described and can be safely used in cost constrained situations.
