Purpose: This study was performed to compare the clinical results and complications of bipolar hemiarthroplasty and internal fixation using proximal femur nail antirotation (PFNA) for unstable elderly femoral intertrochanteric fractures.
Materials and Methods: From May 2008 to September 2010, 74 patients older than 65 years who underwent bipolar hemiarthroplasty(33 patients) or PFNA(41 patients) and followed for more than 1 year after surgery were enrolled in this study. The mean blood loss during operation, mean operation time, radiological results, clinical results, and complications were analyzed by the Student t-test and Chi-square test to compare the two groups.
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.
