  • Go Long!


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


Closed reduction1

Closed Reduction

  • 128º A/P


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 stability

IMHS CP by Smith & Nephew

Rotational Stability

  • Operative


Rotational stability1

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)
