image hip & make sure nothing else will kill them…pain meds and call ortho

42
Q

what is the prognosis of elderly after having a hip fracture?

A

one yr mortality post fracture is 25-30%

43
Q

which type of hip dislocation is most common?

A

posterior

44
Q

ED tx of hip dislocation?

A

1) . attempt reduction in ED under conscious sedation
2) . post-reduction CT to rule out femoral head fractures
3) . protected weight bearing following reduction for 6 weeks

45
Q

when do you not need post reduction films after hip dislocation?

A

when the pt has had a total hip replacement and acetabulum is made of titanium

46
Q

distal Tib/Fib fracture classification

A

Weber- level of fibular fracture relative to syndesmosis
A= below syndesmosis
B = level of syndesmosis
C = above level of syndesmosis

47
Q

ED tx for distal tib/fib fracture

A

if isolated nondisplaced malleoli fracture- conservative tx with short leg walking cast vs boot
displacement of isolated fracture, open, or bimalleolar fracture- ORIF

48
Q

what is the maisonneuve fracture?

A

spiral proximal fibular fracture & distal medial malleolar fracture (and/or deltoid ligament rupture) which COMPROMISES SYNDESMOSIS

49
Q

tx of maisonneuve fracture?

A

it is unstable so surgical fixation is required

50
Q

if you have a distal ankle fracture, what is also important to examine?

A

fibular head!

51
Q

ED tx of tibial plateau fractures?

A

knee immobilizer

52
Q

ED tx of high ankle sprain

A

sprain w/o diastasis or ankle instability = non weight bearing CAM boot or cast for 2-3 weeks
if syndesmosis is unstable = SURGERY

53
Q

ED tx of subtalar dislocation?

A

closed reduction FIRST (sedation and post reduction films)

*open reduction if failed attempt at closed reduction

Q

ED tx of pelvic fracture

A

place binder on them (goes over trochanter), give blood if needed and call ortho

61
