Describe
Dx
posterior fat pad indicative of fx. (anterior fat pad also present but these are sometimes a normal variant).

MOI of Radial head fx
FOOSH
Sx indicative of radial head fx.
Hx consistent w/ FOOSH
Decreased pronation/supination
Describe
Diagnose
Radial head fx.
This photo does not have it - but a posterior fat pad would help to dx this - These are notoriously hard to see

Galeazzi Fx
VERY UNSTABLE - Immediate ORIF
Child presents w/ arm slightly flexed, refusing to use it. No swelling, and tenderness to palpation of radial head. TX?
Reduction-Pressure on the radial head w/ supination and flexion. If the child cannot almost immediately use the arm after get x-ray to r/o fx.
Nursemaids elbow
What action increases the sx/pain of lateral epidondylitis?
Gripping, forearm pronation and wrist extension against resistance (radiates down the forearm).
What action increases pain of Medial epicondylitis?
Pulling activities, forceful extension of elbow against resistance w/ forearm supinated and wrist flexion against resistance
Describe
Dx.
Tx
