MSK V - Hip and Lower Extremity Flashcards
most common etiology of hip fractures? age?
after a fall from standing position in person >50 y/o
what are the greatest risk factors of hip fracture?
osteoporosis, female gender
what is important to determine about the pt if hip fracture?
their baseline ambulatory status
common sx’s of hip fractures?
pain in anterior hip/groin after fall
non-ambulatory
non-weight bearing
external rotation of leg on affected side
what is the most sensitive test to identify a hip fracture?
internal rotation - pt will have pain
physical exam for hip fracture?
pain on palpation over fracture area and pain with active/passive ROM
pain on internal rotation
assess neuro status
what x-rays for hip fracture?
AP pelvis (all the time)
Frog lateral - if pt can tolerate it
when would you order an MRI for hip fracture?
if suspected fx not seen on x-ray
when should pt with hip fracture have surgery?
recommended to have surgery within first 24hrs
why should you NOT delay surgery past 24hrs for hip fractures?
b/c pts will then have 2x the rate of major/minor complications like pneumonia, pressure ulcers, DVT, and death
tx for femoral neck fracture?
cannulated screws or hemiarthroplasty
what pts with femoral neck fx get cannulated screws as tx?
if younger pt like 55 y/o or older pt that is bad surgical candidate (won’t survive hemiarthroplasty)
what is the reason to do hemiarthoplasty for femoral neck fx?
b/c femoral neck fx’s interrupt blood supply to femoral head
tx for intertrochanteric femoral fx’s?
IM nailing (M/C) - force is inside the bone here and device is load sharing
DHS Compression Screw (not as good b/c force is on the outside of the bone)
difference b/w intertrochanteric femoral fx’s and femoral neck fx’s?
intertrochanteric fx’s don’t interrupt the blood supply
femoral neck fx’s do interrupt the blood supply
tx for subtrochanteric fx?
IM nailing
when do you do a hemiarthroplasty?
displaced femoral neck, sub capital hip fx
when do you use cannulated screws for hip fx?
nondisplaced femoral neck
what do patients and family need to understand about hip fractures?
that the surgery is a major surgery and it carries inherent risks
what happens to the people that do survive their hip fx?
return to one level below their baseline ambulatory/ADL status
avascular necrosis risk factors?
chronic steroid use, post-trauma, post-infection
sx’s of hip arthritis?
insidious onset of achy type pain in hip and/or groin
c/o stiffness in morning or after prolonged sitting with “loosening up” after approx. 30 min of activity (“Gelling”)
pain in hip arthritis increased after prolonged what and relieved with what?
Pain increased after prolonged activity, relieved with rest
pain in hip arthritis affects what and causes decreased what?
ADLs and causes decreased ROM
