Presentation Transcript

  1. The treatment of femoral neck fractures and the results of the Gannetkeynote session Hip # 2lecture # O244 Ariaan van Walsum trauma surgeon Medisch Spectrum Twente Enschede The Netherlands & W. Roerdink, J. Vroemen, H. Janzing, T. Winkelhorst

  2. Conflictof Interest Disclosure Form NAME: ADP van Walsum AFFILIATION:MedischSpectrum Twente, Enschede, The Netherlands DISCLOSURE I havethefollowing potential conflict(s) of Interest toreport:

  3. Treatment of femoral neck fractures 35% REVISION RATE IN DISPLACED # 11% IN UNDISPLACED #

  4. Treatment of femoral neck fractures We got a problem!

  5. Biology BIOLOGY IS THE MOTHER OF ALL FIXATION G.R. Girdlestone

  6. Biology Achilles heel 1 Bone healing No cambium layer No periosteal callus Primary bone healing Requires: Anatomical reduction Absolute stability

  7. Biology Achilles heel 2 Viability Remaining vascularisation Reduction Fixation Revascularisation: Fixation stability Implant volume

  8. Why do implants fail?multiple parallel screws or pins • No angular stability • No rotational stability

  9. Why do implants fail?sliding hip screw devices • No rotational stability • During insertion • After insertion • +/- anti-rotation screw • High implant volume

  10. Can we make a better implant?

  11. Dynamic Locking Blade Plate“GANNET” CHARACTERISTICS: • Rotational stability • Angular stability • Dynamic compression • Minimal invasive

  12. GANNETexample Trauma female 57 year

  13. GANNETexample 3 year

  14. GANNET Failure Rate 3,9% for undisplaced fractures • N = 149 • Mean age 69 yrs 13,5% for displaced fractures • N = 192 • Mean age 61 yrs 60% for displaced unreduced fractures • N = 5

  15. CONCLUSIONfemoral neck fractures • AWARENESS! • Indications for Gannet: • Undisplaced fractures • all ages • Displaced fractures • young patients (< 65) • young elderly patients (65 – 75) • individualized on the biology • after anatomical reduction • high risk elderly patients (> 75)
