Femoral Neck System versus Cannulated Screws for Medial Proximal Femoral Fractures: A State-of-the-Art Review of Early Complications and Functional Outcomes
Abstract
Abstract
Objectives
Displaced femoral neck fractures remain a challenging injury, particularly regarding implant selection for internal fixation. The Femoral Neck System (FNS) was developed to improve angular and axial stability compared with traditional cannulated screw fixation.
Methods
A focused literature review comparing FNS and cannulated screws for femoral neck fracture fixation was performed using the Consensus platform, enabling analysis across millions of indexed scientific articles, and complemented by a targeted manual search. Based on relevance, methodological quality, and scientific impact, the 50 most influential studies were included. Early clinical and radiographic outcomes and implant-related complications within the first six months were analyzed.
Results
The available evidence suggests that FNS fixation is associated with lower rates of early mechanical and biological complications and improved early functional recovery compared with cannulated screws, particularly in unstable fracture patterns.
Conclusions
Current evidence indicates that the Femoral Neck System offers a more favorable short-term clinical profile than cannulated screw fixation for medial proximal femoral fractures. While both techniques achieve high union rates when adequate reduction is obtained, the biomechanical advantages of FNS appear clinically relevant within the first six months following surgery
