Back 4

D. 2/3

Front 5

Which of the following is incorrect ?
A. Scaphoid fractures are considered unstable with as little as 1 mm

displacement.
B. The vascular supply to the scaphoid consists of small perforators

solely from the radial artery.
C. A Barton fracture is a fractured distal radius involving displacement of a large fragment of the radial articular surface.
D. A Bennet fracture involves an intra-articular fracture of the base of the thumb metacarpal , with subluxation / dislocation of the

carpometacarpal joint.

Back 5

B. Multiple blood supplies:

1. Radial artery perforators
2. Palmar artery perforators
3. Superficial artery perforators.

Front 6

In regards to elbow dislocations, which of the following is incorrect?
A. The most common type is posterolateral dislocation (90%).
B. Dislocation nomenclature relates to the position of the distal humerus
C. The most commonly injured nerve is the ulnar nerve.
D. Patients tend to hold their arm flexed at 45 degrees.

Back 6

B. Position of the Olecranon fossa to the

distal humerus.

Front 7

Which of the following is incorrect ?
A. The most common type of ankle dislocation is the Posterior type.
B. The Gustilo grading System refers to Open leg fractures with the

associated degree of tissue / skin damage.
C. The Gustilo Grading system has 3 main classification categories.
D. Compartment syndrome can not occur when there is a break in soft tissue in the leg.

It can

Front 8

In regards to Paediatric Supracondylar

fractures, which of the following is correct?
A. It is the second most common Paediatric elbow fracture, after

radial head fractures.
B. The rate of neurovascular complications are as high as 15%.
C. The highest incidence of nerve injury is to the median nerve.
D. The radial artery can frequently spasm, making radial pulse

assessment unreliable for vascular damage, if it is absent.

Back 8

D.

A = Most common Paediatric elbow fracture (60%)
B = 7%
C = Ulnar nerve.

Front 9

Which of the following is correct?
A. Bony injuries occur in up to 20% of shoulder dislocations.
B. A Hill-Sachs deformity is a fracture of the anterior glenoid lip.
C. Luxatio erecta is a posterior shoulder dislocation.
D. A Bankart lesion is a compression fracture of the humeral head.

Back 9

C.

A = 30%
B. = Bankart lesion
D = Hill-Sachs deformity

Front 10

In regards to tibial plateau fractures , which of the following is incorrect?
A. They typically result from direct trauma to the knee.
B. Fracture of the lateral tibial plateau is the most common type.
C. Lateral tibial plateau fractures are associated with injuries to the lateral collateral ligament and anterior cruciate ligament.
D. Medial tibial plateau fractures are associated with lateral collateral

ligament and posterior cruciate injuries.

Back 10

C. Lateral tibial fracture= medial collateral ligament + Anterior cruciate ligament

injuries.

{ Medial tibial plateau fractures = lateral

colateral ligament + Posterior

cruciate injuries }

Front 11

In regards to Achilles tendon rupture, which of the following is incorrect?
A. A Positive Thompson test = calf squeeze = no plantar flexion.
B. The vascular supply to the achilles is adjacent to its insertion into the calcaneum.
C. Risk factors include prior steroid use, flouroquinolones, periodic

strenuous exercise, and older age.
D. The achilles is the longest and strongest tendon in the human body.

Back 11

B. Vascular Supply to the achilles Tendon is

2-6 cm proximal to the calcaneus insertion.

Front 12

Which of the following is incorrect?
A. The syndesmosis of the ankle is one of 3 main groups of ligaments

stabilising the ankle joint.
B. The anterior talofibular ligament is the weakest of the ankle's lateral ligament complex.
C. Traction is contraindicated in femoral fractures if there is sciatic nerve injury, or an open fracture.
D. With phalangeal joint fractures / dislocations of the hand, digits are

frequently radially deviated.

Back 12

D. Ulnar deviated due to the radial collateral ligament rupturing 6 times more commonly than the ulnar collateral ligament .
