Hardware
Across
- 2. Lag by design is a partially threaded screw that is designed to only purchase which cortex
- 3. stress sheilding concept, all internal fixation absorbed physiological stress so bone will resorb
- 9. lag technique you overdrill which cortex with a fully threaded screw
- 13. compression plate, oval shaped, deeper holes, allows for eccentric drilling and axial compression
- 14. polyglyconate that is the longest acting absorbable suture material
- 17. Limited contact plates have what kind of contact with periosteal tissue? grooves are located on underside of plate
- 18. iron, chrome, carbon, nickel
- 19. redistributes force through plate and interfragmentary compression
- 21. Neutralization plate with without interfragmentary screw
- 22. component of stainless steel that gives it hardness
- 24. Poliglecaprone, hydrolyzed in 3-4mo, @2wks 20-30% tensile strength
- 26. a malleable metal made of nickel and titanium that solidifies at body temp
- 27. least reactive suture to tissue
Down
- 1. anatomic reduction, Early ROM, atraumatic dissection, stable fixation
- 4. 2 screws across 3 cortices or 1 across 4 cortices
- 5. step not needed for threaded screws
- 6. 1/4 components of stainless steel this component prevents breakdown
- 7. plate that uses tension force on the convex side of injury
- 8. plate that secures small medial malleolar fragments
- 10. polyglactin 910, hydrolyzed 3-4 mo, 65% tensile strength at 14 days
- 11. law the force needed to extend/compress a certain distance is proportional to that distance
- 12. Purpose of tapping a screw cuts threads to allow what to be applied during screw insertion to generate compression instead of dissipation by friction
- 15. same as AO, bascially a translation for the german term
- 16. implant hardware that is inert and does not affect MRI
- 20. what step can be skipped with cancellous screws?
- 23. screw that is self cutting and cortical
- 25. component of stainless steel that pts may have allergy to
