1 Which one of the following is true regarding
collagen?

Latin for ‘strand’.
B. Type 1 collagen is formed from three identical ‘alpha’ chains.
C. Type 3 collagen is formed from two different ‘alpha’ chains.

E. Collagen is stabilized by polymerization.
2 With regards to anticoagulants in microsurgery:
A. Heparin and antithrombin III have similar mechanisms of action.
B. Unfractionated and fractionated heparins have different proportions
of anti-Factor Xa and antithrombin activity.
C. Heparin-induced thrombocytopenia is a more frequent complication
of unfractionated prophylactic heparin than of fractionated
prophylactic heparin use.

than 16 years of age.

3 Which landmark publication related to free tissue
transfer is correct?
A. The first successful thumb replantation was performed by Komatsu
and Tamai in 1967.
B. The first clinical series of free tissue transfers was published by
Nakayama in 1969.
C. Cobbett performed the first successful free great toe-to-hand
transfer in humans in 1968.
D. McLean and Buncke performed the first free omentum flap in 1971.
E. None of the above is true.
4 Concerning composite tissue allotransplantation,
which of the following is true?
A. Corticosteroids are used for both maintenance therapy and
treatment of acute rejection episodes and act by inhibiting NF-B
activation and inflammatory cytokine production.
B. Antithymocyte globulin (ATG) is an induction agent which binds cell
surface antigens, and depletes T cells.
C. Tacrolimus (FK 506) blocks the production of IL-2 and has been
shown in recent studies to possibly speed up nerve regrowth.
D. Mycophenolate mofetil (MMF) prevents T-cell proliferation and
differentiation.
E. All of the above.
5 In relation to free tissue transfer, which one is true?
A. The anterolateral thigh free flap, by definition, is based on the
descending branch of the lateral circumflex femoral artery.
B. The superficial inferior epigastric artery pedicle is absent in
approximately 5% of cases.
C. The skin paddle of the fibula osteoseptocutaneous free flap is an
unreliable indicator of the blood supply to the fibula bone.
, 1 Basic principles and basic science
D. Some surgeons are capable of performing microsurgery without the
aid of a surgical microscope.
E. None of the above is true.
6 According to Mathes and Nahai:
A. The posterior interosseous artery flap is a Type C fasciocutaneous
flap.
B. The lateral arm flap is a Type C fasciocutaneous flap.
C. The scapular flap is a Type C fasciocutaneous flap.
D. The deltopectoral flap is a Type C fasciocutaneous flap.
E. None of the above is true.
7 With regards to toe-to-hand transfer:
A. The dominant blood supply to the great toe is the first plantar
metatarsal artery in 25% of cases and the first dorsal metatarsal
artery in 75% of cases.
B. A metacarpal hand results when all its fingers have been amputated
proximal to the proximal phalanx, with or without thumb involvement.
C. Repair of the toe extensor tendon(s) in the hand should be
performed after an accurate finger cascade has been achieved by
flexor tendon repair(s).
D. When reconstructing a Type IIC metacarpal hand by toe-to-hand
transplantations, finger reconstruction should usually precede
thumb reconstruction.
E. Nicoladoni was the first to report pedicled great toe-to-hand transfer.
8 Regarding free tissue transfer:
A. According to Koshima, supramicrosurgery (or supermicrosurgery) is
defined as microvascular dissection and anastomosis of vessels
measuring less than 0.5mm.
B. In 1960, Jacobson and Suarez reported successful experimental
microvascular anastomoses as small as 0.9mm in diameter.
