Femur Neck Fixation

The Femoral Neck Fixation (FNF) is indicated for femoral neck fractures, including basilar, transcervical, and subcapital fractures, in adults and adolescents (12-21) in which the growth plates have fused or will not be crossed.

Twin Lock-BCP Shaft Screw, Dia 5.0 mm
Provides superior stability by securely anchoring in the bone, minimising angular and rotational movements during weight-bearing
Offers enhanced grip and fixation strength in osteoporotic bone, ensuring reliable support for effective fracture repair

Femur Neck Fixation Screw

  • Provides rotational stability through a diverging design between the screw and blade.
  • Allows implant placement even in a small femoral neck

Femur Neck Fixation Blade

  • Provides angular stability by fixing the angle between the blade and screw
  • Features a dynamic design with up to 20 mm of controlled collapse, without lateral protrusion for the first 15 mm

End Cap
Preventing Backout
End caps secure the ends of fixation devices, preventing screws or nails from backing out or migrating due to patient movement and loading

Protecting Soft Tissue
End caps provide a smooth surface at the device’s end, reducing the risk of irritation or damage to soft tissues—particularly crucial in areas with minimal soft tissue coverage, such as the femoral neck

Size Options
End caps are available in sizes ranging from 6 to 16 mm, allowing for customisation based on the required amount of compression and specific surgical needs

Twin Lock-BCP Screw, Dia 5.0 mm
Securely fixes the plate to the femoral shaft bone during fracture repair
Provides stable fixation by locking securely into the plate, preventing movement and maintaining alignment

3-Point Stabilisation
Stable Fixation:

  • Reduces micro-motion at the fracture site, which is crucial for proper healing

Distribution of Forces

  • Evenly distributes mechanical forces across the fracture site, reducing stress concentrations at any single point

Prevention of Rotational Instability

  • Counters rotational forces, especially during walking, to maintain fracture alignment and promote healing

Enhanced Compression

  • Multiple points of fixation make it easier to achieve and maintain compression across the fracture site
  • Compression encourages bone contact and stabilisation, which is essential for primary bone healing

Reduction in Complications

  • Provides a robust fixation that minimises risks such as non-union, malunion, and implant migration

Femur Neck Fixation Plate with Support

  • Designed at a 130° angle to closely match the bone structure
  • Ensures angular stability by fixing the angle between the plate, blade, and shaft screw.
  • Accommodates standard 5.0 mm locking and shaft screws
  • Minimises the implant footprint on the bone, offering a compact alternative to three cannulated screws

Controlled Collapse

  • The implant offers up to 20 mm of controlled collapse
  • End caps are available in sizes of 6, 8, 10, 12, 14, and 16 mm. For example, 8 mm compression requires a 12 mm end cap
  • Compression can be adjusted in 2 mm increments (e.g., 4, 6, 8, 10, 12, 14, and 20 mm), allowing precise control of collapse
  • Controlled compression enhances bone fragment contact and promotes better bone healing.
  • Accommodates natural micro-movements during weight-bearing, aiding the biological healing process

Prevention of Varus Collapse & Enhanced Angular Stability

  • The femoral neck is prone to varus collapse under weight-bearing forces
  • The combination of the plate, blade, and two supporting shaft screws provides robust support against these forces, maintaining correct anatomical alignment
  • This configuration enhances angular stability, ensuring proper alignment throughout the healing process
