ABFAS CBPS TREATMENT ACTUAL TEST
QUESTIONS WITH VERIFIED CORRECT
ANSWERS
●● Most common 5th metatarsal fracture
Answer: Avulsion fracture (about 50% of 5th met fractures)
●● normal IM between 4 and 5?
normal lateral bowing angle?
Answer: IM= 6.5-9.0
bowing angle=2.6
●● What is the Myerson procedure?
Answer: use of EHB in correction of HAV.
●● What is biologic fixation?
Answer:
●● stewart classification
Answer: 5th met base fracture
,●● benefit of ropivicaine over bupivaine
Answer: less cardiotoxicity, but much more expensive.
●● most common cause of peroneal spastic flatfoot?
Answer: tarsal coalition
●● What causes a local anesthetic to have faster onset?
Answer: Lower pKa
●● Where does the extensor apparatus originate/insert
Answer: There is no specific area that it originates from or inserts
●● What is a geode in medical terms??
Answer: A 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: Technetium binds to hydroxyapatite and is seen in areas of high
bone turnover.
Gallium binds to WBC's and is seen in areas of increased inflammation.
If used together, Technetium should be given first.
●● Which ASA class has 2-3x risk for post-op complications.
Answer: ASA class III: specifically a pulmonary complication
●● How is LMWH excreted?
, Answer: through the kidneys; should be avoided in those with kidney
failure
●● Which local anesthetic is lease likely to cause methemoglobinemia?
Answer: Marcaine
although is is very rare for the other local anesthetics anyway.
●● What does exposure mean in medical research?
Answer: Any factors or characteristics that may explain/predict a certain
outcome.
●● What types of fixation provide compression and also osteogenesis.
How do things provide osteogenesis?
Answer: Lag screws and dynamic compression plates.
The lack of motion stimulates osteogenesis
●● Why is alcohol used to dilute phenol?
Answer: phenol is insoluble in water, but is soluble in alcohol.
●● Should diuretics be held prior to surgery?
