Radiology Flashcards
what scan is more sensitive for fractures
CT
what might lower limb immobility lead to
DVT, PE , pneumonia
why is a CT better than xray for fractures
its cross sectional and multi planer
unaffected by overlapping
why might some fractures be difficult to see on xray
due to overlapping anatomical strucutres and dont show when undisplaced
what can provide detailed info about bone marrow and show undisplaced
MRI
do xrays show soft tissue
no
what can provide high resolutionn of soft tissue especially tendons
US
what is a major advantgae of MRI
it can show deep inside body or within joints
sites where US struggles
if pelvis is only site of injury what test is done
XRAY
what test is doen for poly trauma
CT
what test for sports related pelvic soft tissue ijury
MRI
what are the main causes of hip dislocation
car crash and sports
when is blood supply very limited to femoral head
intrascapular fracture
which fracture doesnt affect blood supply of femoral head
extrascapular
what predisposes to tendon ruptures
steroids
RA
diabetes
what does damage to hyaline cartilage predispose to
OA
what are femoral shaft fractures usually due to
major trauma , high energy injuries
what are distal radius fractures due to
fall on outstretchd hand
olecranon fracture cause
from falling onto elbow
tibial plateau fractures
high energy injuries in young, low energy in adults due to osteoporotic bone
are long leg casts commonin adults
no but they are in kids as they heal quick
what does a malunion fracture mean
heals in a non anatomic position
nonunion
broken bone fails to heal altogteher
hypertrophic non union
bone healing complication in which the bone ends (fracture fragments) fail to fuse or heal together, even though they show signs of abundant bone growth.
