Pathology 5 - MSK Flashcards
meniscal tear - gradual or traumatic
normally traumatic
meniscal tear - MOI
twisting of the the knee when it is a semi-flexed position with the foot planted on the ground
hyperflexion
meniscal tear - no traumatic tear
due to degeneration
pivoting or squatting movement may be enough to cuase a tear
meniscal tear - function of the men
absorb shock and distribute forces
meniscal tear - is the medial or the lateral normally effected more
medial - it is more firmly attached to the tibia
meniscal tear - population
sports - cutting and pivot
older - degnerative tears
meniscal tear - sym
pain and tenderness of joint line
swelling
loss of ROM
complaints of locking and catching
feeling of instability
meniscal tear - lab test
MRI is the test of choices
meniscal tear - special test
mcmurreys
apley - compression and distraction
thessely’s
ext and flexion overpressure
meniscal tear - conservative treatment or surgery
age
previous activity level
location and extent of tear
meniscal tear - tear of the out 1/3
more likely to heal compared in inner tear becasue of blood supply
myositis ossificans - what is it
characterized by calcification of the muscle
bone growth in the mucles
myositis ossificans - cause
improper treatment of of a muscle strain of contusion
fail to apply cold or heat after injury
intense massage too soon after injury
- factors that distrub normal healing
myositis ossificans - often occur in what muscles
muscle prone to traumtic injury
- leg and arm muscles
myositis ossificans - primary imaging
xray
Spondylolisthesis - what it is
anterior slip of a superior vert on the inferior vert
Spondylolisthesis - is common what what spinal level
L4-L5
Spondylolisthesis - sym
Back pain - spinal stenosis, cauda equina syms
back pain increases - over head lifting , prolonged standing, getting in or out of the car, walking on stairs or incline
radiating pain
motor or sensory loss
no sig neuro deficits
Spondylolisthesis - population
> 50 year of age
black women
Spondylolisthesis - imaging
plain radiograph
MRI might be used to rule out other pathos
what directional preference for disk herniation
extension extercises
what directional preference for spondy
flexion excercises
what is the difference between de quiverians and dupuytren’s
dup: finger, nana
de: inflammation of the FPL and EPB
what age do we normally see death with duchenes muscular dystrophy
30s recent
do girls or boys have higher incidence of JRA
girls
diagnosed as a toddler
what are the basic clinical syms for JRA
joint swelling, pain, and stiffness
what muscle is most often inplicated with Lateral epi
ECRB
what is gerby’s tubercle
facet on the lateral aspect of the upper part of the tibia, just below the knee joint and adjacent to the proximal tibio-fibular joint,
where the iliotibial tract interts
wartenberg syndrome effects what nerve
superfical branch of the radial nerve is entrapped
only has sensory presentations
does radial tunnel syndrome or PIN have pain vs muscle loss
raidal tunnel: pain
PIN: muscle
wartenberg syndrome special test
tinel sign
finklesteins test
What type of meniscal tear is described as a vertical longitudinal tear displaced into the intercondylar notch?
bucket handle men tear
often occur in an area of good blood supply
Horizontal (cleavage) men tears
run parallel to the tibial plateau through the mid-substance of the meniscus
Longitudinal (vertical) men tears
run perpendicular to the tibial plateau and parallel to the long axis of the meniscus
Complex men tears involve what
some combination of horizontal, longitudinal, or vertical tears
displaced men tears involve what
either complete detachment of a piece of meniscus or flipping of a piece of the meniscus that is still attached to the rest of the meniscal body
Developmental disabilities occur between the what ages
birth and 22
how do Acquired disabilities occur
an acute event or sudden injury
stroke or spinal injury.
what is a Hill-Sachs lesion
characterized as an impaction fracture of the posterior superior humeral head
frequently diagnosed in patients who have repeatedly sustained anterior glenohumeral dislocations
MCL resists what kind of movement
valgus forces at the knee
ER if the tibia
Clicking or catching in knee range of motion may be indicative of pathology of the:
meniscus
what does a springy end feel indicate
non capsular end feel
loose cartilage, meniscal tissue within joints
Duchenne muscular dystrophy:
proximal > distal
or
distal > proximal
muscular: proximal to distal
GBS: distal to proximal (DPt)
Duchenne muscular dystrophy bladder function
Bladder and bowel function is typically spared.
what age does Duchenne muscular dystrophy show up
3-6 years of age
Legg-Calve-Perthes disease age ranges
as young as 2 or as old as 15
Which tendon of the shoulder is most commonly associated with impingement?
supraspinatus tendon
attaches on the superior facet of the greater tubercle placing it in close proximity to the acromion process.
Legg-Calve-Perthes disease girls are boys more prevelent
boys
surgical recovery. time for the medial men
4-6 months
what is the gait abnormality normally associated with muscular dystrophy
waddling gait
lumbar lordosis and proturuding abd
The muscles of the pelvic girdle deteriorate, which causes the patient to use circumduction to compensate for gluteal weakness.
