seizures and electrical shock
deltoid malfunction, which nerve
axillary
most common hip dislocation
posterior
H and P for ligament tear
pain welling that is worse with joint stress
decreased ROM
ligament instability
what imaging confirms ligament tear
MRI
what is the knee triad injury
medical collateral
lateral meniscus

5th metacarpal neck
fracture humerus puts what nerve at risk
radial
management for hip fracture
anticoagulate since at risk for AVN and DVTs
which bone fracture puts one at major risk for blood loss
pelvic
which back pain is worse at rest and better with activiy
ankylosing spondylitis
radiating pain that is worse with standing and walking

what is erb duchenne
superior trunk injury
caused from shoulder dystocia usually
will have waiteris tup
claw hand injury
ulnar nerve
will have weak finger adduction
poor 4th and 5th finger flexion
lumbrical weakness
clinical features of axillary nerve injury
cannot should abduct or elevate
klumpke palsy
posterior and medial cord injury from hyperabduction of the arm
will have claw hang, poor wrist and hand function assoc with horner syndrome
Tx for osteoporosis
prevention
bisphosphonates decrease osteoclast activity, increase bone densiity and decrease fracture risk
selective Estrogen R modulators like raloxifene help increase bone density
pulsatile teriparatide (recombinanat PTH) stimulates osteoblasts and bone remodeling
why is hormone replacement not recommended anymore for osteoporosis
increased risk for breast cancer, DVTs, CAD and stroke
signs of osteopetrosis
increased fractures, blindness or deafness, bony compression of nerves, impaired healing
labs in osteopetrosis
decreased Hb, decreased Hct
increased acid phosphatase, increased CK
Tx for osteopetrosis
transfusion marrow components for osteoclast production, activity restriction
signs of paget disease of bone
deep bone pain, increased fractures, tibial bowing, kyphosis, increased cranial diameter, deafness
labs in pagets disease of bone
increased alk phos
increased urine hydroxyproline
normal Ca and phosphate
my hat no longer fits
paget disease
Tx pagets of bone
bisphosphonates and calcitonin
osteogenesis imperfecta
defective production collagen
fractures with minimal trauma, blue sclera, skin and teeth deformities, possible deatness, joint hypermobility
do not give this for acute attack gout
allopurinol
how does allopurinol work
inhibit uric acid formation
how does probeneci work
inhibits kidney uric acid resorption
what is pseudogout made of
Calcium pyrophosphate dihydrate deposition disease
joint aspirate is + birefringent, rhomboid crystals
pseudogout
Tx pseudogout
NSAIDs and colchicine
msot common cause septic joint
Staph sureus
labs in septic joints
increased WBC, inc ESR and CRP
joint aspiration will show numerous WBC with high Neutrophils
decreased glucose
+ cultures
Tx gonorrhea septic arthritis
IV ceftriazone and doxy
Tx S aureus septic joint
penicillinase R penicillin
Tx gram negative septic joint
aminoglycoside
msot common cause osteomyelitis in sickle cell patient
salmonella
common osteomyelitis in IV drug users
pseudomonas
erythema chronicum migrans
bulls eye
lymes
what happens in lymes early disseminated state
myocarditis cardiac arrhythmias heart block bells palsy sensory-motor neuropathies, aseptic meningitis or meningoencephalitis
What happens in lymes late disseminated stage
few months to years later, chronic synovitis, monoarthritis or oligoarthritis, subacute encephalopathy or polyneuropathy
labs for lymes
ELISA and western blot for Ab
Tx lymes
doxycycline, amoxicillin or cefuroxime
what causes OA
chronic noninflammatory joint degeneration involving articular cartilage deterioration
risk factors for OA
advanced age, FMH, obesity, previous joint trauma, repetitive joint stress
joint stiffness and pain that worsens with activity and weight bearing
worse in DIP in hands with heberden nodes and PIPs bouchard nodes
degenerative joint disease
XR in degenerative joint disease
osteophyte formation, joint space narrowing, subchondral bone sclerosis and subchondral bone cyst formation
RA vs OA
RA affects both sides body in symmetric distribution
DIP joints spared
OA asymmetric may only affect one joint
DIP frequently involved
bony protuberances on DIP
heberden nodes
bony protuberances on PIP
bouchard nodes
Tx OA
activity modification, heat, analgesics, NSAIDs, weight loss, PT, corticosteroid, or hyaluronic acid injections
what causes RA
chronic inflammatory disorder. synovial hypertrophy with granulation tissue formation on articular cartialge (pannus)
HLA in RA
HLA DR4
signs Sx RA
PIP and MCP joints
symmetric polyarthropathy
morning stiffness with pain
swan neck deformity
flexed DIP with hyperextended PIP
RA
boutonniere deformity
flexed PIP
RA
other manifestations RA besides hand joints
subcutaneous nodules, pleuritis, pericarditis, scleritis
labs in RA
RF + in 75%
+ anti citrullinated peptide Ab ACPA
+ ANA in 40%
joint aspiration will show 5,000-50,000 luekocytes
false + RPR or VDRL
