MS pathologies Flashcards
Types of ARTHRITIS ?
Osteoarthritis (OA)/Degenerative Joint Disease (DJD)
Rheumatoid Arthritis (RA)
Gouty Arthritis
Septic Arthritis
Osteoarthritis (OA) aka Degenerative Joint Disease (DJD) patho ?
Progressive degeneration and loss of articular cartilage.
Underlying bone is damaged, with formation of new bone (osteophytes) at margins.
What is the key in dx OA ?
key thing of OA is osteophytes - dx degenerative condition (different from the others)
Is OA non inflammatory to inflammatory ?
NON - inflammatory
OA/DJD sxs ?
Slow onset, brief stiffness in AM or after overuse or inactivity
No generalized sxs of fatigue or malaise - not systemic disease just in joints itself
Usually additive
Commonly affects knees, hips, spine, wrists, DIP> PIP, not MCP ( helps you distinguish if from RA cause RA does not have DIP)
**athletes and obese cause pounding on joints , RA is more symmetrical **
OA / DJD PE, signs ?
↓ AROM and PROM, crepitus
Rarely warm or red (cause it is not inflammatory)
Bony enlargement (from osteophytes) - new simulated bone
Heberden’s nodes – nodules at DIP jt.
Bouchard’s nodes –nodules at PIP jt.
OA: Heberden’s nodes – nodules at ___ jt.
DIP
**osteophyte formation but they are not red swollen tender and stuff they are just hard a painless and the MCP joints are spared **
OA: Bouchard’s nodes –nodules at ___ jt.
PIP
OA / DJD - Treatment ?
NSAID’s
Pain meds (Tramadol) - opoid
Joint injections
Arthroplasty
rooster cone into the mixer and they inject it into the joint (synvisk)
RA patho ?
Autoimmune disorder, unknown trigger, slow onset
Chronic inflammation of synovial membrane
-secondary erosion of cartilage and bone - damage to ligaments and tendons
**more slow onset
and they feel really crappy cause it is systemic and inflammatory
erosion of cart. and bone and damage to ligaments and tendons **
RA sxs. ?
Symmetrically additive - usually both knee
Insidious onset, becomes chronic with exacerbations and remissions
Stiffness, lasting 1+ hours in AM or after inactivity (take them a while to get p and going)
Generalized sxs of weakness, fatigue, weight loss, fever
Females > Males
RA PE, signs ?
↓ AROM and PROM
Tender and warm joints, seldom red
+/- subcutaneous nodules on ulnar surface
PIP and MCP most, rarely DIP
Ulnar deviation of fingers
Swan neck deformity
Boutonniere deformity (less common)
Rheumatoid arthritis – swan neck and boutonniere deformities ?
top right is the swan hyper extension
inter osseous muscle atrophy cause they are not using the muscles look at bottom pic
Acute gouty arthritis what crystal in the joint cause what type of reaction ?
Monosodium urate crystals in joint cause an inflammatory reaction
Acute pseudogouty arthritis what crystal in the joint cause what type of reaction ?
(Pseudogout – calcium pyrophosphate crystals)
Acute gouty arthritis - symptoms ?
Sudden onset of severe pain, often 1st MTP joint
but also instep, ankles, knees, elbows ( classically big toe)
+/- hx of recent, excessive intake of food (purines - high protein - shrimp) or ETOH, fasting or injury
Usually one joint on first episode
Repeat episodes become more frequent and more severe
Acute gouty arthritis PE, signs ?
Very tender, hot and red
No stiffness, ↓ ROM is due to pain
Can be mistaken for cellulitis, septic arthritis
**looks like septic arthritis **
Acute gouty arthritis labs ?
↑ serum uric acid (but can be normal in 30% of patients) -
not diagnostic though - gives us a clue
What is dx study for GOUT ?
Definitive Dx – aspirate joint fluid
Acute gouty arthritis tx ?
NSAIDs - acute
Education re: prevention ( avoid triggers)
recurrent / chronic GOUT - allopurinol
Septic arthritis is a MS ____________ .
emergency
Can leave a permanent functional disability
**needs to be dx really quickly with bone destruction cause it really does not grow back **
Septic arthritis (SA): Bacteria in a joint causes ?
vascular congestion - taking up more space
increased synovial fluid - more space being taken up
destruction of articular cartilage
destruction of bone within one week of
onset - losing bone in one week
SA: Bacteria comes from one of 3 routes, which are ?
Hematogenous - IV drug user, LUPUS, strep or UTI ( small infections that can cause it )
Direct inoculation - severe trauma, surgery
Contiguous - someting nearby like a soft tissue abcess that erodes into the joint
SA sxs ?
rapid pain ( look like GOUT),
swelling
↓ROM
SA PE ?
fever
x-ray reveals effusion and narrowed articular cartilage ( as crowding takes place)
SA labs ?
joint aspirate – turbid, gray or creamy with ↓viscosity. Do a gram stain and C&S
SA tx ?
dependent on cause and culture
heme tx that
abscess - treat that
May need aspiration and ATB’s (not PO more parenteral)
May need surgical open debridement ( debride out dead bone)
SA prognosis ?
Dependent on virulent the bacteria and joint involved
Hip and ankle are more likely to have permanent damage
-finger heal better
**depend on how quick you are to figure it out and how much destruction has been done
from a replacement - then remove hardware and clean it out and then put it back in **
Other arthritides ?
Gonococcal (type of septic) type of septic joint
Psoriatic
Lyme
Etc.
Shoulder Rotator cuff made of the tendons of 4 muscles , which are ?
Supra spinatous
Infra spinatous
Teres minor
Subscapular
What muscle is most commonly involved in RC injuries etc ?
Supra spinatous
most commonly involved cause of location
Rotator cuff muscle purpose ?
They reinforce the joint capsule
What RC muscle can you not palpate ?
subscapularis
Impingement syndrome patho ? and what results ?
When the acromion, coracoacromial ligament, AC joint or coracoid process impinge (pinch) on bursa, biceps tendon and rotator cuff
Inflammation results
**something soft tissue wise is getting pinched by hard tissue -bone **
Impingement syndrome sxs ?
Gradual onset of ant and lat shoulder pain
Can’t sleep on affected side ( so sleep on back or other side )
Impingement syndrome PE, signs ?
+ impingement sign
↓ abduction ( cause it recreated pinch
Pain with flexion (near to ear)
Impingement syndrome tx ?
NSAIDs x 10-14 days
Rest
Stretching exercises
Injection of 10 ml mix of cortisone (depomedrol) & 1%
lidocaine - works right away
**quick and long term relief **
Rotator cuff tendinitis is one type of ?
impingement
Rotator cuff tendinitis is ?
the cuff is pinched under the acromion
Rotator cuff tendinitis caused by ?
repetitive overhead motions that cause the rotator cuff to be pinched under the acromion (throwing, swimming, etc.) painters
**acute - edema and hemorrhage
chornic - fibrosis and scarring down **
Rotator cuff tendinitis sxs. ?
pain when arm is overhead
Rotator cuff tendinitis PE, sign ?
+ impingement sign
Neer (ear) and Hawkins
Rotator cuff tendinitis tx ?
activity modification
PT
NSAIDs
injection
Rotator cuff tear from ?
Can be from chronic or
acute injury
**not inflamed it is now teared **
Rotator cuff tear chronic ?
Repeated impingement ex: heavy lifting
Rotator cuff tear acute ?
FOOSH (fall on an outstretched hand)
Rotator cuff tear can be ?
Tears can be partial or complete and are graded by severity
Rotator cuff tear sxs. ?
weakness
pain
trouble with ROM
Rotator cuff tear PE, signs ?
+ Drop Arm test ( abduct arm and then we ask them to lower it down and it will eventually just fall - not smooth)
Impaired active abduction – end up shrugging instead
Rotator cuff tear tx ?
depends on severity, and how active they are,
Rest
PT
surgery
**dont have to treat these it just depends on the patient **
How long does it take to heal a Rotator cuff tear after arthroscopic debridement ?
Takes 6-12 months after arthroscopic debridement
of a partial tear for a throwing athlete to resume athletics
(devastating to athletic career)
Calcific tendinitis patho ?
Degenerative process of a tendon, with deposits of calcium salts
Usually involves the supraspinatus tendon
More common in females, + 30y.o.
**deposit of Ca in the tendon **
Calcific tendinitis sxs ?
may be acute or chronic episodes of pain
Calcific tendinitis PE, sign ?
arm held close to the side, all directions of movement increase the pain (any movement hurts cause Ca salt are being pinch and moved on)
**the sub acromiun bursa may get inflamed as well **
Calcific tendinitis Tx ?
Remove the calcifications (arthroscopy)
Reduce the inflammation
-through cortisone injection
Biceps tendinitis patho ?
Inflammation of the long head of the biceps tendon
May resemble a rotator cuff tendinitis, or the two may co-exist
**treatment are a lot the same
lateral rotation will expose areas a lot better **
Biceps tendinitis sxs. ?
anterior shoulder pain
Biceps tendinitis PE, signs ?
+ Yergason test (resisted supination) and it aggravated biceps tendon
**elbow at 90 against the body and resist supination **
Biceps tendinitis tx ?
Activity modification
rest
NSAIDs
Steroid injection into sheath of tendon (if into tendon, can degenerate or rupture the tendon – “Popeye sign”
have to be really careful with these
Biceps rupture what defect ?
“Popeye defect”
**still some function of biceps and maybe no surgery for olde rman but a young kid then yea surgery to reattach it
tx - surgical correction if there is a complete tear of a tendon head **
Adhesive Capsulitis aka ?
“Frozen Shoulder”
