MSP Exam 1 Questions With Correct
Answers 100% Verified.
Fracture - Answer✔To break; discontinuity of bone
MC lesion in bone - Answer✔Fracture
Is a fracture a pathology - Answer✔Yes
Pathologic fracture - Answer✔Pre-existing conditions that affect bone locally or systemically
that compromise bone structure such that it becomes more susceptible to structural failure
What has to be overcome in a bone such that it fails - Answer✔The tensile and compressive
strengths
Are all fractures pathologies - Answer✔Yes
Are all fractures pathologic fractures - Answer✔No
Bone pathologies vs pathologic fractures - Answer✔Bone pathologies (pre-existing conditions)
predispose for pathologic fractures
What factors influence fracture repair - Answer✔Blood supply, nutrition, age, infection,
location, severity
Phases of fracture repair - Answer✔1) inflammation
2) repair
3) remodel
Inflammatory Phase - Answer✔Onset - 10 days
Reparative phase - Answer✔1 week - few months
Remodeling phase - Answer✔Several weeks +
Onset - 2 days post - Answer✔1) rupture of blood vessels (soft tissue AND bone)
2) hematoma fills "gaps", surrounds injury and seals off fracture

3) tearing of periosteum (what hurts)
4) necrosis of bone and soft tissue
2 - 5 days post - Answer✔1) fibrin mesh develops
2) fibroblasts migrate into area
3) cartilage forms
4) necrosis + macrophage activity continues
5 - 10 days post - Answer✔1) procallus forms replacing fibrin mesh
2) macrophages continue
Radiographic findings - inflammatory phase - Answer✔Discontinuity and displacement
Reparative phase - Answer✔1) osteoclasts/PMN clean up debris
2) extensive neovascularization ***
3) callus formation
Radiographic findings - reparative phase - Answer✔Widening of fracture and hazy cloud
Remodeling phase - Answer✔1) callus seals the bone
2) bone adjusts strength/shape
Radiographic findings - remodeling phase - Answer✔Solid mature callus
Who's law describes the remodeling phase? - Answer✔Wolffe's Law
Clinical Union - Answer✔When cast is removed; implies stable fracture
Malunion - Answer✔Heals with residual deformity
Delayed Union - Answer✔Fails to heal up to 6 months post fracture
Non-union - Answer✔Fails to heal after 6 months
Pseudoarthrosis - Answer✔Non-union fracture heals with pseudo joint
Transverse fracture - Answer✔High velocity injury; often pathologic aka Paget's "banana"
fracture
Oblique fracture - Answer✔Very common; 45 degrees to long axis
Spiral fracture - Answer✔Torsion/axial compression; pointed ends

Are bone bruises seen on radiographs? - Answer✔No
Bone bruises - Answer✔Hemorrhage, edema, trabecular microfracture seen on MRI
Open fracture - Answer✔Breaks the skin
Closed fracture - Answer✔Does not break skin
Greenstick / Torus fracture - Answer✔Incomplete fracture in skeletally immature individuals
from buckling/bending
Avulsion fracture - Answer✔Forcible ripping or tearing of tissue
Tearing away of bone fragment from pull of ligament, tendon or muscle - Answer✔Avulsion
fracture
Clay Shoveler's / Coal Miner's fracture - Answer✔Avulsion of a lower cervical segment spinous
process
Occult fracture - Answer✔Radiographically invisible fracture
MC occult fracture - Answer✔Scaphoid
Why should you re-radiograph occult fractures? - Answer✔Discontinuity widens from
macrophage and osteoclast activity
Comminuted fracture - Answer✔Two or more fragments that have separated from the bone
aka butterfly fragment
Noncomminuted fracture - Answer✔Two fragments
What causes compression and impaction fractures - Answer✔Axial compression
Compression fractures - Answer✔Vertebral fractures from axial compression
Impaction fractures - Answer✔Extremity fracture from axial compression
Stress fracture - Answer✔Repetitive stress causing gradual formation of microfracture
Alkaline phosphatase - Answer✔Secreted by osteoblasts when depositing bone
When would you see elevated alkaline phosphatase - Answer✔In very aggressive disease
(osteosarcoma) or multiple large fractures
ESR - Answer✔Erythrocyte Sedimentation Rate - how fast RBC settle
Elevated ESR indicates - Answer✔Inflammatory process
