Comparison between the Results of Internal Fixation Using Proximal Femur Nail Anti-rotation and Bipolar Hemiarthroplasty in Treatment of Unstable Intertrochanteric Fractures of Elderly Patients

Results: The volume of blood loss during the operation was statistically lesser in the PFNA group (P<0.05) and operation time was not statistically different between the two groups (p=0.73). The bipolar hemiarthroplasty group showed a statistically better outcome than the PFNA group in the beginning of weight bearing (p<0.05), the hospital stay (p<0.05). The degradations of Koval score and modified Harris hip score of the bipolar hemiarthroplasty group were statistically better than those of the PFNA group (p=0.03, p=0.02). The bipolar hemiarthroplasty group showed a statistically lower incidence of mechanical(9.1%, p=0.01) and general(12.1%, p=0.00) complications than the PFNA group. Conclusion: In elderly patients, bipolar hemiarthroplasty is thought to be one of the effective treatments for unstable femoral intertrochanteric fracutures when considering complications and clinical outcomes.
