Objectives • How I Handle These? • Do I Bone Graft? • What am I worried about? • Let’s Make it Easy
Getting Best Images Not the best way to get AP Better way to obtain AP
Getting Best Images How to obtain lateral w/flouro Mark on machine rotation to obtain desired view
Getting Started Landmarks outlined and ideal location for insertion of starting guide pin
Opening Reamer Tip: Stop at the lesser trochanter
Guidewire Making sure you are centered with guidewire on both views
Tissue Protector for reaming. Ball tip in place to maintain reduction Getting Prepared for Nail
C-Arm • Know your tech and communicate • Make sure you can image everything • Entrance site • Fracture • Interlocking holes • If you can’t see it, don’t start!!!
My Answer: NO • Reduce Fracture • Solid fixation • WBAT • BUT…one type make you think about this
Technical Consideration • Essentially all current nail designs have radius of curvature greater than native elderly femur…The nail is much straighter than the bow
The Starting Point: Don’t Be TOO Anterior True lateral view key
Fracture Alignment Nail Follows Path Of Reamer On Radiograph Reamer Trajectory In Proximal Fragment Dictates Reduction Tip: Don’t ream until reduced!
Using the Tools • Use of Channel reamer or equivalent • Maintain portal • Decrease soft tissue damage • Prevent proximal malunions (Russell, OTA 2006)
Reduction Aids • “Finger” reducer may be helpful • Guide wire does not reduce fracture, finger does
Reduction Aids • Ball spike pusher • May use Schantz pins • Strategic placement • Anterior/lateral
TAD Matters Still go for </= 25 in IMN
What is Our Role? • Define condition • At a minimum, start on calcium and vitamin D • Not only prevents further fractures, but saves lives • Our patients listen..to their surgeons
Examples of household hazards Decorations on railing Throw rugs with edge curled up: Watch out!
Summary • Fracture Table • See before you start • OK to open • Reduction aids • Remember: Why did the fracture happen?
