A Retrospective Study Comparing Proximal Femoral Nail Anti-Rotation With Cementless Bipolar Hemiarthroplasty for Unstable Femoral Intertrochanteric Fracture

Abstract

Background: Intertrochanteric femoral fractures are one of the most common types of bone fractures that are usually caused by severe direct or indirect force. It has also been estimated that nearly 50% of all the fractures are intertrochanteric fractures and the remaining are unstable fractures. Also, it has been found that the mortality related to hip fractures is as high as 15-20%. With an increase in the life expectancy of people, there has been a substantial increase in the number of patients with postmenopausal or senile osteoporosis.
 Aim: To compare Proximal femoral nail anti-rotation with cementless bipolar hemiarthroplasty for unstable femoral intertrochanteric fracture
 Methods: It was a retrospective study carried out at the Government Medical College, Baramati for a period of 1 year. One hundred patients were included for the scope of the study. Out of which 50 patients belonged to the PFNA group, and 50 patients belonged to the CPH group.
 Results: The number of patients in the PFNA group was 50 and that in the CPH group was 50. Both groups show male preponderance. The mean age among both the groups was almost the same, and there was no statistically significant difference among the two groups regarding the mean age. The mean operation time for PFNA was 54.15±16.1 mins, and that of the CPH group was 76.69±15.89 mins. The mean bleeding time for PFNA was 133.12±33.16 ml, and that of the CPH group was 289.25±44.01 ml. There was no statistically significant difference among the ASAA grade scores of the two groups. There was no statistically significant difference among the Evans-Jensen classification of the two groups. The mean length of hospital stay for PFNA group was 7.89±2.0 days, and the mean hospital stay for CPH group was 6.54±1.9 days.
 Conclusion: The current study depicted that CPH and PFNA are both safe and effective methods of treating elderly patients suffering from intertrochanteric fractures. However, it was found in the current study that CPH was found to have more mean operative time and increased blood loss. Still, the recovery and hospitalization time was almost similar in both the groups. Both the groups had almost similar ASA and Evans Jensen scores that made both the techniques equally safe
