Elbow and Forearm Flashcards
most common type of elbow dislocation?
posterior; both radius/ulna
fracture association with elbow dislocation
ulnar fracture
msot common elbow fracture in adults? kids?
radial head fracture in adults, supracondylar fracture in peds
fat pad sign
elevation of anterior/posterior fat pads; posterior fat pad is diagnostic for fracture , usually radial head
sail sign: elevation of the anterior fat pad, less specific
essex lopreseti fracture/dislocation
- radial head fracture
- tearing of the interosseous membrane
- ulnar dislocation at the distal radioulnar joint (DRUJ)
monteggia fracture-dislocation
- ular fracture
2. radial dislocation at elbow
galeazzi fracture-dislocation
- distal third radius fracture
2. ular dislocation at DRUJ
Colles fracture
distal radius fracture, dorsal angulation; usually intraarticular
MOA for Colles fracture
FOOSH; most common injury to distal forearm
Hutchinson/chaufferu’s fracture
fracture radial/lateral disal radius into the styloid and radiocarpal joint
perilunate dislocation
lunate aligned with radius, but capitate is not;
lunate dislocation
lunate dislocated volarly; capitate still relatively aligned with radius;
which is associated more with fracture? lunate or perilunate
perilunate
scapholunate ligament injury common sign?
terry thomas; increased scapholunate interval –> SLAC
causes of SLAC
scapholunate advanced collapse
from scapholunate chronic ligament injury, osteoartritis, CPPD arthropathy, chronic untreated dissociation
