Trauma Flashcards
Inlet iliac oblique best view to determine
AP screw position within pubic ramis
Inlet obturator oblique view best to determine
Position of supraacetabular screw within tables of ilium
Indications for fixing glenoid/scapular neck fractures
Translational displacement >1cm, angulation >40 deg
Obturator oblique view best for
Anterior column/posterior wall, ruling out joint penetration
Best view for AC joint
Zanca
Southwick angle is used to determine
Severity of SCFE slip; >60 deg = severe
Boundaries of ilioinguinal approach: medial window
Medial to external iliac artery/vein
Boundaries of ilioinguinal approach: middle window
Between external iliacs and iliopectineal fascia/psoas
Boundaries of ilioinguinal approach: lateral window
Lateral to iliopectineal fascia/psoas
Provides stability to thumb MCPJ in flexion
Proper collateral ligament
Cozen fracture and associated deformity
Pediatric proximal tibia, valgus deformity
Define pilon Chaput fragment
Anterolateral tibial fragment, attached to AITFL
Define pilon Volkmann fragment
Posterolateral tibial fragment, attached to PITFL
Anteromedial coronoid fracture is associated with:
Elbow LCL rupture and varus posteromedial rotatory instability
Deforming forces of Bennett’s fracture
EPL, adductor pollicis longus, abductor pollicis longus
Most common tarsal fracture in lateral subtalar dislocation
Cuboid
PER
High, oblique fibula fracture & medial mal fracture
PAB
High, comminuted fibula fracture & medial mal fracture
SADD
Vertical medial mal fracture
Iliac oblique best view to determine
Evaluate trajectory relative to sciatic notch
Outlet obturator oblique best view to determine
Start for supra-acetabular screw (teardrop view)
Lateral sacral view best to determine
Trajectory of iliosacral screws
Indications to pin both hips in unilateral SCFE
Endocrine disease, open triradiates, or age <10 (girls)
Lesser tuberosity transfer is indicated for
Reverse Hill-Sachs (ie, posterior dislocation only)
