Hardware

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

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
