Miller's Joints Flashcards
Nerve blocked in adductor canal block
- what area of knee not blocked?
saphenous n
- posterior knee is not blocked-> thus can have “pseudo DVT” pain sx’s
Artery at risk when performing lateral retinacular release
lateral superior genicular a
Absolute indication for patella resurfacing
RA
difference in surface for ongrowth vs ingrowth
ongrowth has pits not pores
diff btw annealing and melting
both are for eliminating free radicals
annealing heats to submelting points=> this maintains structural stability while melting reduces its mechanical properties
caclium stearate in polyethylene is…
bad
goal combined anteversion
35-45
metal ion lab findings with trunnionosis
elevation in metal ions
- cobalt> chromium (5:1)
outcomes comparing THA vs hemi for fx after 2 years
THA with better functional scores and lower revision rates after 2 years
most common mechanism for nerve palsy s/p THA
- overall recovery rate
compression via hematoma
- 50%
hip approach with highest risk for HO
direct lateral
treatment for intolerable psoas impingement from THA
revise cup if 8mm or more prominent
if not=> psoas release
number of dislocations in THA that triggers revision
3 strikes you’re out
main benefit of dual mobility
increases the head diameter and jump distance
definition of jumbo cup
- increase complication of…
> 62mm women
66mm in men
- assoc with higher dislocation rate
