PFNA intramedullary nail

Unlike traditional plates placed externally on bones, intramedullary nails serve as an “internal support” positioned along the bone’s mechanical axis. This centralized fixation method minimizes the lever arm, providing exceptional resistance to bending and rotation. It allows patients to initiate functional exercises and partial weight-bearing early on, significantly accelerating recovery. Additionally, the procedure typically employs minimally invasive techniques, with insertion through small incisions distant from the fracture site. This approach maximally preserves blood supply and soft tissue integrity around the fracture, creating an optimal biological environment for bone healing. Consequently, the risk of infection and nonunion is significantly reduced.

PFNA intramedullary nail

1,Cannulated intramedullary nail adopts the design of 5° angle of proximal abduction to make nail into the apex of the trochanter more smoothly.

2,Lag screw is optional in blade and threaded types.

3,Anti-rotation screw design can prevent the nail off and nail slipping.

4,The shank of the lag screw has an asymmetrical groove to resist the anti-rotation screw and prevent slippage.

5,Threaded lag screw is better adapted to young patients.

6,The soueezing of the blade lag screw causes compression to cancelous bone to increase bone density.

7,The bone cement hole desian ot the blade lag screw head increases the pullout resistance of the screw and provides a firm fixation for patients with osteoporosis.

Instrument features:

1,Light transmissive aiming amm.

2,Special punching frame can play a role in on-site mediation.

3,Multi-axial swing and dial guide design for easy control of the insertion depthof the intramedullary nail.

4,Ergonomic aiming amm design effectively solves the problem of body positionblocking.

5,Tools are marked in different colors for easy intraoperative operation.

6,The thread design on sleeve prevents the tool from falling out during surgery.

Conclusion

In summary, PFNA offers an exceptional solution for unstable intertrochanteric femoral fractures, particularly in elderly patients with osteoporosis, through its innovative helical blade and intramedullary fixation design. This approach delivers a minimally invasive, stable, and rapid recovery solution.
