ABFAS RAPID FIRE
#MUST KNOW
FAS BOARDS:
Neuroma Sx: injure DTML->adjacent contractures
Triple arthrodesis complication: NON-union TN common
Mitchell bunion: distal metaphysis, rectangular wedge, shortening, transfer metatarsalgia
Gastroc recession: sural nerve/>14cm above calc tuberosity safe (posterolateral)
Sequestrum: necrotic bone that is separated by granulation tissue from surrounding living bone
Involucrum: new bone that has formed around dead bone. Involucrum can become perforated
Cloaca: openings/tracts in the involucrum
Acute osteo:
+Tc (phase 3)
+Gallium
Chronic osteo:
+Tc
-Gallium
Ga-67: Diffuse uptake=Soft tissue infection
In-111:
+=Acute OM
-=Chronic OM
Cellulitis:
-Tc
+Gallium
Congenital vertical talus: LATERAL forced PF=*no correction*
Cellulitis: > signal T2/poorly defined
Bone scan shows:
Bladder/Kidneys, facial, sternum, scapula tips, spine, SI J’s, epiphyseal growth centers
1st MTP fusion position:
10-15 DF
10-20 Valgus
Bunion: ABH mm(slides beneath met H)->pulls on proximal phalanx->pronation
