MSC ORT Final (Trauma) Questions withverified correct answers
What is the benefit of external fixation? - ANSWER-limb lengthening, tissue
preservation, & deformity correcting
fragment fractures - ANSWER-transverse, linear, oblique (non displaced),
oblique (displaced), spiral, greenstick, comminuted
intra-articular vs extra-articular fracture - ANSWER-intra: distal radius fracture -
used volar distal radius plate
non-displaced v partially displaced v 100% displaced - ANSWER-non displaced:
see fracture but didn't move
partial: medially displaced partially
100%: ML view of the knee and distal moved posteriorly displaced; what
happened to distal part in respect to proximal piece
transverse fracture - ANSWER-occurring across the bone, at a right angle to the
long axis
cause: shear lateral force or direct blow injury
linear fracture - ANSWER-runs parallel to the long axis of a bone; aka fissure
fracture
cause: blunt force trauma where impact energy transferred over a wide area;
uncommon
oblique fracture - ANSWER-diagonal fracture
cause: injury to the bone as the result of a fall, accident, or other trauma; bending
mechanism of injury; common occurrence
spiral fracture (aka torsion fracture) - ANSWER-fracture lines spiral up/down the
bone
, cause: body twists while the extremity is firmly planted; rotating mechanism of
injury; common occurrence
large zone than oblique fracture
greenstick fracture - ANSWER-fracture only on 1 side of the bone, other side
only bends
cause: bending trauma on softer pliable bones
typically only occurs in pediatric patients, have to be flexible enough to allow
fracture on 1 side and not the other
comminuted fracture - ANSWER-bone is splintered or crushed into a number of
pieces
cause: result of a high impact injury to the bone such as fall, accident, GSW,
severe crush injury, or other trauma, osteoporotic bone is more fragile and more
susceptible
avulsion fracture - ANSWER-tendon or ligament pulls off a small piece of bone
and remains attached to it - attachment of tendon/ligament to bone is stronger
than bone, very rarely are these fixed
hip fractures:
what type of fractures are these? - ANSWER-cervical (neck), intertrochanteric,
subtrochanteric
Fragility fractures
cervical neck - ANSWER-fracture in the neck of femur, fragility fracture
intertrochanteric fracture - ANSWER-fracture between greater and lesser
trochanters of the femur, fragility fracture
greater trochanter: attachment point for abductors and flexors, takes load and
redirects it to the shaft of the femur
subtrochanteric fracture - ANSWER-below and within ~5cm of the lesser
trochanter, fragility fracture
Unstable because all the weight is redirected laterally
