Traumatic Disorders of the MS System Flashcards
7 days to 7 weeks pain is blank
subacute
acute pain is blank to blank days
0-7
chronic pain is blank
longer than 7 weeks
local death of bone due to a loss of blood flow
osteonecrosis
increased deposition of bone, increased matrix, normal calcification
acromegaly
decreased deposition, decreased formation of matrix and hypocalcification
osteoporosis
mechanical failure of bone
fracture
excessive fluid production that is swelling within a joint
effusion
swelling due to excess fluid outside a joint
edema
between synovial lining and articular cartilage of a joint that is a disorder of the joint
adhesions
excessively stretched and elongated joint
joint laxity
tight and shortened joint
joint contracture
tissue response due to irritation, damage, injury…. local reaction of living tissues to irritant
inflammation
four clinical signs of inflammation
rubor, tumor, calor, dolor
tumor is
swelling
rubor is blank
redness
calor is blank
heat
bleeding within a muscle or joint due to a direct blow creating increased fluid in the area, pain, limited function
contusion
muscle belly can develop blank from a contusion
myositis ossificans
due to a tension overload of a ligament
ligamentous sprain
break off a fragment of bony attachment by ligament
avulsion
chronic overstretching of muscle or tendon and is most common at musculoteninous junction
muscle strain
muscle damage due to increased tension applied to an already contracted muscle
charley horse
t2 imaging shows blank
pathology
t1 imaging shows blank
anatomy
sprain where a few fibers are lost from ligamentous integrity
1st degree
sprain with greater disruption of fibers with some loss of joint stability
2nd degree
sprain with a complete loss of structural or biomechanical integrity
3rd degree
disruption of a joint with partial loss of continuity between the articular surfaces
subluxation
separation of bones connected by fibrous tissue
diastasis
disruption of a joint with complete loss of continuity between the articular surfaces
dislocation
two ways to restore congruency after subluxation or dislocation
closed manipulation, open reduction
any defect in the continuity of a bone that usually damages surrounding tissues
fracture
fractures are confirmed by blank
x rays
this may have to be used to identify a stress fracture
radionucleotide bone scanning (scintigraphy)
fracture healing process
hematoma, callus, ossification, remodeling
fusiform mass around the fracture. ossification occurs initially at the periphery and gradually moves centrally.
callus
callus develops blank and blank as it matures
trabeculae, cortex
two factors affecting fracture healing
age, config of fracture, blood supply
children heal fractures in blank
4-6 weeks
adolescents heal fractures in blank
6-8 weeks
adults heal fractures in blank
8-10 weeks
medical conditions like blank and medications like blank may affect fracture healing
diabetes mellitus, prednisone
shaft of a long bone
diaphysis
the portion of the developing long bone between the diaphysis or shaft and the epiphysis
metaphysis
end of a long bone
epiphysis
no loss of continuity or integrity of the bone
simple fracture
several pieces of bone in the fracture
comminuted fracture
fracture within the joint
intraarticular
fracture outside the joint
extra articular fracture
fracture horizontal
transverse
fracture diagonal
oblique
longitudinal fracture is blank
vertical
muscle forces draw the distal fragment into the proximal fragment type of fracture
compression
fracture where loose fragment that does not involve the complete cortex
butterfly
fracture with numerous fissures radiating from the actual point of injury
stellate fracture
fracture that is separation of a bone fragment from its cortex at an attachment of a ligament or tendon
avulsion
fracture from fatigue
stress fracture
fracture where bone ends are in continuity
greenstick
closed treatment of fractures includes blank
casts, splints
open treatment of fractures includes blank
plates/pins/rods
three abnormal healings of fracture
malunion, delayed union, nonunion
Ecchymosis
Bruising/discoloration
Bone will remodel according to the stresses placed on it
