South Africa, 9th-24thth May, 2009.
Additional Indications • Go Long!
Fundamental Principles • Closed fracture reduction • Minimally Invasive • Rotational Stability • Prevention of Collapse • Biomechanical Strength
Closed Reduction • PORD Device for correction of Posterior Sagging
Closed Reduction • 128º A/P
Minimally Invasive • Trochanteric Entry • Medial/Lateral Bend
Minimally Invasive • Minimized diameter of nail • Proximal • Distal • What does minimized diameter provide?
IMHS CP by Smith & Nephew Rotational Stability • Operative
Smith & Nephew InterTAN Stryker Gamma Nail Depuy ATN Rotational Stability • Post Operative • Double Axis Fixation vs. Single • Double Axis vs Double Close • Double Axis vs Double different Diameter VeroNail
Fundamental Principles Summary • Closed fracture reduction • Minimally invasive • Rotational stability of the femoral head • Prevention of collapse • Biomechanical strength
Hip Fracture Treatment Goals • Quick to Rehab • Return to Pre Fracture Situation Ambulation!
Sliding Cephalic Screw • Self Drilling/Self Tapping Tip Design • Non Cannulated • XCaliber Thread Design
Convergent (Fixed) Cephalic Screw • Self Drilling/Self Tapping Tip Design • Non Cannulated • XCaliber Thread Design
Only loose particles of drill debris „Interdentating effect“
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 • 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)
