BACKGROUND
Intertrochanteric femur fractures are typically treated with proximal femoral nails. There are two varieties of proximal femoral nails in our study: PFNA2, which has a single proximal blade, and normal PFN, which has two proximal screws.
AIM
Our study compares functional results and implant-related problems in individuals treated for proximal femur fracture using PFNA2 nails versus conventional PFN nails.
MATERIAL AND METHODS
After obtaining ethical clearance from Institutional ethical committee, this prospective study was conducted in the Department of Orthopaedics in Sri Madhusudhan Sai Institute of Medical Sciences and Research from Nov 2022 to Nov 2023. A series of 50 cases were included in the study. After obtaining prior informed and written consent from the patients. Fracture diagnosis confirmed by clinical examination and radiography. Pre-anaesthetic evaluation done as per protocols. 25 Patients underwent PFN nailing and 25 Patients underwent PFN- A2 nailing. Post operatively follow up was done until 6 months to assess various outcomes namely fracture
healing, incidence of post-operative complications, rehabilitation and functional outcome.
RESULTS
Implant A2-PFN nails has better results than implant standard PFN nail in terms of operative time, operative blood-loss and functional outcome.
CONCLUSION
We concluded from the study that, in comparison to standard PFN nails, PFNA2 nails minimises surgical time, blood loss, and radiation exposure. When compared to standard PFNPFNA2-treated patients are able to bear weight quickly. PFNA2 does not cause too many implant-related issues including screw backing out and cut-through of screws in the femoral head (also known as the z-effect and reverse z-effect). Consequently, we draw the conclusion that PFNA2 nails are better than standard PFN nails. nail, PFNA2 nails offers substantially superior functional outcomes and a greater union rate.
