Facts about patella tension bands:
- > 50% hardware removal rate
- 30% extensor lag
- 25% with persistent quad weakness
- 1mm articular incongruity associated with quad weakness post op
Meniscus tears in setting of tibial plateau fractures:
- most commonly lateral, Schatzker 2
- eval under direct visualization using submeniscal arthrotomy
What structure blocks reduction of the Stener lesion
- Adductor pollicis
- Ulnar nerve innervates this
These alternative meds inhibit platelet function:
- garlic
- ginkgo biloba
- ginseng
Most common bleeders in pelvic trauma:
venous plexus > SGA >Obt a > Pudendal a
This complication is associated with TSA for proximal humerus fracture with concomitant rotator cuff tear?
Glenoid component loosening
What is the msot likely cause of pain and dysfunction after a talar neck fracture dislocation?
Subtalar osteoarthritis
- NOT osteonecrosis of the talus
Second generation vs First generation femoral nails:
second generation nails can utilize a cephalic lag screw
Damage control principles with a closed head injury:
- DCO is appropriate to minimzie blood losses and allow the brain injury to equilibrate
- do an Ex-fix for long bone fractures
- Cerebral perfusion pressures should remain >70mmHg
Most common complication of non-op displaced midshaft clavicle fractures?
nonunion
Coverage of Pseudomonas after a puncture wound?
Give a fluoroquinolone
Interpreting Kocher’s criteria for pediatric septic hip:
0 = 0.3% 1 = 3% 2 = 40% 3 = 93.1% 4 = 96%
Deformity that can result from pediatric femoral shaft fractures?
Recurvatum deformity
- due to injury to the proximal tibial physis from trauma OR traction pin placement
LEAP Study Data on Amps vs Salvage:
- satisfaction at 7 years is similar between groups
- return to work is similar betwen groups
- amputation costs are 3x salvage costs
Risk factors for AVN following femoral neck fracture
- young patients
- high energy mechanism of injury
NOT Risk factors:
- time to fixation >24 hours
- ipsilateral femoral shaft fracture
