UE part 2 trigger Flashcards
what humeral fx is MC in children
type A supracondylar
what Xray view is used for radial head visualization
oblique (radcap view, 45degre)
What humeral fracture is MC overall
type C intercondylar
weakness with flexion and adduction of the wrist suggests disruption of what nerve
ulnar
radial = extension
what nerves/arteries do supracondylar humeral fractures typically affect
radial artery/median nerve
epicondylar fx = ulnar and radial nerve
when do you see fat pad sail signs? what do they indicate
distal humeral fractures.
indicates intra articular bleeding or occult fx.
what type of distal humeral fracture must have NO angulation or displacement in order to avoid doing ORIF.
Type A supracondylar.
Type B can have displacement of <2mm and still use conservative tx
what is the difference in splinting for Type A and B distal humeral fractures
A - long arm cast at 90d (at neutral position i assume)
B - long arm cast at 90d either pronated (medial condylar fx) or supinated (lateral condylar fx)
what is the MC nerve affected in olecranon fxs?
ulnar
look it just runs right over it!:)
tx is long arm posterior splint with neutral forearm and to squeeze a rubber ball 5 mins/day.
olecranon fx with <2mm displacement
if >2mm then ORIF
if open then IV abx and consult ortho
pain/tenderness along lateral aspect of elbow. Limited ROM especially w pronation/supination.
radial head/neck fx
Sling with AROM after 24-48 hrs flexion, ext, pronation and supination. FU w ortho in 1 week
mason T1 radial head/neck fx
Sling and splint with ortho follow up in 2-3 days to discuss ORIF is tx for what type of radial head/neck fx
mason type 2-3 radial head/neck fx
what type of radial head/neck fx requires immediate ortho consultation
type IV (fx+ dislocation)
arm held semi-flexed adducted and pronated with refusal of ROM and tenderness over radial head
nursemaids elbow (radial subluxation0
elbow pain with wrist extension and supination is suggestive of what
lateral epicondylitis
point tenderness 1 cm distal to the epicondyle
medial or lateral epicondylitis
pain in the elbow with wrist flexion and pronation is suggestive of what
medial epicondylitis
when can you use a counterforce brace as treatment
epicondylitis
when do you get imaging for olecranon bursitis
only when there has been trauma involved
if we aspirate a large and non septic olecranon bursitis and cultures come back negative what is the next step
reaspirate and reculture.
if negative again and persistent swelling then aspirate again and give 1 mL corticosteroid injection
