fundamental principles
Fundamental Principles
  • Closed fracture reduction
  • Minimally Invasive
  • Rotational Stability
  • Prevention of Collapse
  • Biomechanical Strength
closed reduction
Closed Reduction
  • PORD Device for correction of Posterior Sagging
minimally invasive
Minimally Invasive
  • Trochanteric Entry
    • Medial/Lateral Bend
minimally invasive1
Minimally Invasive
  • Minimized diameter of nail
    • Proximal
    • Distal
  • What does minimized diameter provide?
rotational stability1

Rotational Stability
  • Post Operative
    • Double Axis Fixation vs. Single
    • Double Axis vs Double Close
    • Double Axis vs Double different Diameter

VeroNail

fundamental principles summary
Fundamental Principles Summary

  • Minimally invasive
  • Rotational stability of the femoral head
  • Prevention of collapse
  • Biomechanical strength
hip fracture treatment goals
Hip Fracture Treatment Goals
  • Quick to Rehab
  • Return to Pre Fracture Situation

sliding cephalic screw
Sliding Cephalic Screw
  • Self Drilling/Self Tapping Tip Design
  • Non Cannulated
  • XCaliber Thread Design
convergent fixed cephalic screw
Convergent (Fixed) Cephalic Screw
  • Self Drilling/Self Tapping Tip Design

Conclusions

1. Fine machine thread is well

suited for cancellous bone

2. Predrilling of a screw hole

in cancellous bone leads

to reduction of

the holding power

distal locking screw
Distal Locking Screw
  • Pegged locking screw design
  • Threaded for near cortex
  • Head of screw has outer thread for ease of extraction (Do not bury head of Locking Screw)
