subchondral cyst
Insertion of EDB - ANSWER ->Extensor apparatus near
base of proximal phalanx. changes to X-ray machine for
fiberglass cast - ANSWER ->increase mA by 1.5x
What motion unlocks the knee during gait cycle? -
ANSWER ->Pronation of the
STJ, this causes the femur to rotate laterally which will
unlock the knee
,Which inhaled anesthetic is the most cardioprotective? -
ANSWER ->isoflurane
What is the half life of heparin? - ANSWER ->6 hours
Difference between technetium and gallium - ANSWER

Gallium binds to WBC's and is seen in areas of increased
inflammation.
If used together, Technetium should be given first.
