Outcomes Of Intertrochanteric Femur Fracture Treatment With Proximal Femoral Nail Anti-Rotation (PFNA)

Abstract

Background: In elderly people, common injuries are caused because of low energy trauma and osteoporosis. These common injuries are called proximal femoral fractures. The category of proximal femoral fractures includes pertrochanteric fractures, femur fractures, subtrochanteric fractures, and intertrochanteric fractures. Intertrochanteric fractures are hip fractures that are common in old people.

Objective: Our research aims to evaluate the functional results when intertrochanteric fractures are cured with Proximal Femoral Nail anti-rotation (PFNA). 

Study design: A cross-sectional study

Place and Duration: This study was conducted at Dow International Medical college, Dow University of Health Sciences, Karachi hospital from December 2021 to December 2022

Methodology: All of the patients were having type III and type IV intertrochanteric fractures (Boyd and Griffin) for about 1 week. PFNA with a helical screw (240 millimeters) was used to treat the participants. After the treatment, participants had to visit the hospital after 2 weeks in the starting. Later, they had a monthly follow-up for the next 6 months. Harris Hip Score (HHS) was used to assess the functional outcome in every visit.

Results: Overall, 80 participants were treated with PFNA in this research study. The mean age was 49.51±12.31 years. A total of 4.66 days were the mean duration of the fracture. Boyd and Griffin type III fracture was seen in the majority of the participants. All participants achieved the radiological union at 15.4 weeks. The mean HHS was 84.52 at the 6th monthly follow-up.

Conclusion: The majority of the participants showed good and excellent results when intertrochanteric fractures were cured with Proximal Femoral Nail anti-rotation (PFNA).
