Intertrochanteric fracture, PFN vs PFN A2, functional and radiological outcome.Abstract
Background: Stable fixation is necessary for the best recovery from intertrochanteric fractures, which are common in the elderly. Although both the Proximal Femoral Nail (PFN) and its variant, the Proximal Femoral Nail A2 (PFN A2), are commonly used implants, there are currently few studies comparing their results and our study aims to evaluate the clinic-radiological and functional outcomes of intertrochanteric fractures treated with Proximal Femoral Nail versus Proximal Femoral Nail A2.
Methodology: A comparative study was conducted among 60 patients with each group includes 30 intertrochanteric patients and treated with PFN & PFNA 2 at tertiary hospital in Kuppam. Clinical outcomes were assessed using parameters such as duration of surgery, blood loss. Radiological union was evaluated through follow-up X-rays. Functional outcomes were measured using the Harris Hip Score (HHS) at regular intervals postoperatively.
Results: PFN A2 group achieved a higher mean MHHP score and superior long-term functional outcomes, while maintaining better anatomical alignment and lower Tip apex distance, indicating improved fracture reduction stability and reduced complication risks, compared to the PFN group. On comparing two groups we found significant MHHP Score at 3 & 6 months, Neck shaft angle and Tip apex distance (p<0.05). No significant difference was observed between the two groups in the duration of union.
Conclusion: With minor variations in surgical and early postoperative parameters, PFN and PFN A2 both yield satisfactory results for intertrochanteric fractures. The surgeon's preference and the fracture pattern may influence the implant selection. Additional long-term research is required to confirm these results.
