MSK misc Flashcards
What is the MC ligament injured in ankle injury
anterior talofibular ligament
what is the “dinner fork deformity” fx
colles fx
(dorsally angulated extra-articular distal radius fracture)
What is the garden spade deformity fracture
smith fx
(extra-articular metaphysis fracture of the radius with volar angulation and displacement)
What x-ray views are needed to evaluate for shoulder dislocation
axillary and “Y” view
Shoulder dislocation:
what is a bankart lesion
fracture of glenoid
Shoulder dislocation:
What is the Hill-sach’s lesion
dent in the humeral head
what artery could be damaged with femoral neck fx
medial circumflex femoral artery
is anterior or posterior dislocation more common in hip dislocations
Posterior= 90%
(hip adducted, flexed, internally rotated)
what will be seen on x-ray in posterior hip dislocation
femoral head superior to acetabulum
(PS)
what will be seen on x-ray in anterior hip dislocation
femoral head inferior to the acetabulum
(AI)
Knee injuries should make you worried about injury to what artery
popliteal artery injury
(dx w/ CT angio)
what nerve is commonly injured with knee dislocation
peroneal nerve
(foot drop)
is a knee dislocation an optho emergency? what is key to tx
OPTHO EMERGENCY
early reduction is key
positive birefringement crystals
Pseudogout
MC location for herniated disc of cervical spine
C5-C6/C6-C7
what is the gold standard for dx of osteomyelitis? What is the x-ray triad?
gold= bone aspiration
X-ray triad: demineralization, periosteal reaction, bone destruction
+Finklestein test
(patient’s thumb is placed in the palm of the hand and the wrist is abruptly deviated to the ulnar aspect of the wrist, causing pain on the radial aspect.)
DeQuervain’s Tenosynovitis
What is used to ensure radial and ulnar artery flow, particularly when evaluating a ganglion cyst
Allen’s test
What 3 special tests are used to evaluate for rotator cuff tear/tendinopathy
empty can test, full can test, arm drop
What 3 special tests are used to evaluate for subacromial impingement?
Neers
Hawkins
Drop arm
what is the most sensitive test for an ACL tear
Lachmans
What are two special tests for eval of Meniscus tear
McMurray test/Apley test
+Thompson test
Achilles rupture
patient with instability of the knee in all directions should make you think of what
tibiofemoral dislocation
(nerve injury: common peroneal nerve
Artery injury: popliteal artery)
what two groups of meds increase risk of achilles tendon rupture
fluoroquinolones
glucocorticoids
