Q

Patient had improperly fitted axillary crutch and suffered
injury to a branch of the brachial plexus. Which is the most likely finding?

A. Weakness of arm abduction
B. Hand of benediction
C. Ape hand
D. Cyclist palsy
E. Weakness in extending the forearm and wristdrop
A

E.

The affected nerve with improperly fitted crutches
is the radial nerve. Yes, the first impulse for this
question is to think axillary nerve is the answer
because it’s an axillary crutch. BUT THAT’S
WRONG. The correct answer is radial nerve!
The axillary nerve, with the posterior humeral
circumflex artery actually courses much higher
posteriorly via the quadrangular space.
The radial nerve, along with the deep brachial
artery courses posteriorly via the triangular
interval and is more susceptible to injury from the
axilla.
Weakness of arm abduction - axillary nerve
Hand of benediction – Median nerve
Ape hand – median nerve
Cyclist palsy – ulnar nerve
Weakness in extending the forearm – radial nerve

Q

Which of the following is not involved in the transmission of weight while standing?

A. Sacrum
B. Pelvis
C. Femur
D. Tibia
E. Fibula
A

E

The fibula is just a bone for anchoring muscles. In
fact, it’s so insignificant, you can use it for bone
grafting! The part used for grafting is the middle
third because this contains the nutrient artery.

Q

A 5-year-old male presented with painless testicular mass. If the mass proved to be a malignancy, the earliest affected lymph nodes would be:

A. Lumbar (aortic) lymph nodes

nodes initially. Remember that the origin of the
gonadal arteries is the aorta, therefore the
lymphatics will also course similarly.
