MSC Week 5 Trauma UPDATED ACTUAL
Exam Questions and CORRECT Answers
4 most commonly fractured bones - CORRECT ANSWER - ankle, vertebral body,
proximal femur, distal radius
3 main causes of falls in elderly - CORRECT ANSWER - low blood pressure, dementia,
clumsiness
describe a fracture - CORRECT ANSWER - what bone, location, intra/extra articular, type
of fracture,displaced, angulation
6 types of fracture fragments - CORRECT ANSWER - transverse, linear, oblique, spiral,
comminuted, greenstick
pathological fracture - CORRECT ANSWER - due to another another disease like cancer
fracture from torque - CORRECT ANSWER - spiral
butterfly fracture - CORRECT ANSWER - comminuted or multifragmentary
colles fracture - CORRECT ANSWER - falling down palms forward, arm in front..
FOOSH
most common fracture classification in ortho? - CORRECT ANSWER - AO/ OTA
diagnostic imaging types - CORRECT ANSWER - xray, mri, ct scan
, compartment syndrome - CORRECT ANSWER - tissue is extremely swollen, body eats
away at own tissue, common with tibia fractures
how were fractures traditionally treated before internal fixation - CORRECT ANSWER -
splints, casts , traction, amputation, immobilization, external fixation

threaded/partially threaded
difference between cortical and cancellous screws? - CORRECT ANSWER - cortical has
smaller thread pitch and thread height
functions of a screw - CORRECT ANSWER - compression, connecting two fragments
together, directs a lateral motion via rotational force
5 Key functions of a plate - CORRECT ANSWER - neutralization, buttress, compression,
tensionband, bridging
buttress - CORRECT ANSWER - prevents gliding in one direction, doesn't need to be too
large of a plate, used for intraarticular fractures, primary healing
LC-DCP - CORRECT ANSWER - Limited-contact dynamic compression plate. Scalloped
underside, creates less bone to plate contact which is better for blood flow, even stiffness when
compared to a regular DCP (regular DCP's buckle where the holes are)
