Imaging Quiz 2 Flashcards

mature bone cell

cells that secrete materials needed to form bone

cells that breakdown or resorb bone tissue

Alignment, Bone density, Cartilage, Soft Tissues

outgrowth of bone near joint margins

osteophyte that is isolated, pointed, and forms at a soft tissue attachment site (i.e. heel spur)

a partial dislocation where joint surfaces are no longer aligned

white/bright and appears lighter than cancellous bone because it is more dense

fluffy, smudged, coarsened, lacy

random proliferation of osteoblast and osteoclast activity and looks like cotton wool. (i.e. Paget's disease)

indistinct trabeculae (i.e. osteomalacia)

emphasis of trabecular bone due to loss of bone (i.e osteoperosis)

delicate trabeculae (i.e. thalassemia)

whiter/brighter due to increase in bone density

bone beneath articular cartilage layer

bone infection

bone death (avascular necrosis)

no, too difficult to parse out between muscles etc

angular cut through bone

twisting/looping fracture

damage to intraarticular cartilage can create joint difficulties later in life

fracture due to normal loading on abnormal bone or repeated and minor trauma on normal bone

a fracture that occurs due to disease (i.e. tumor on bone)

bone healing stops at soft callous phase, fail to unite

fracture heals in poor alignment (angular or rotation)

slipped (type 1)

metaphyseal (type 2)

articular-epiphyseal (type 3)

complete metaphysis and epiphysis (type 4)

crushed (type 5)

pain, pallor (lack of color), paresthesia, paralysis, pulselessness

cellular stage, vascular stage, primary callus, bony callus, mature callus

fragment of bone pulled away from body due to loading via muscle or ligamentous structure

shaft is fractured on the tension side, cortex and periosteum remain intact on compression side

impaction fracture that results in buckling of the cortex

deformation of bone
