1. Which of the following Lauge-Hansen stages represents a fracture of the medial malleolus
or rupture of the deltoid ligament in a Supination-Eversion injury?
A. Stage 1
B. Stage 2
C. Stage 3
D. Stage 4
Answer: D
Conceptual Explanation: In the Lauge-Hansen Supination-Eversion (SER) classification,
Stage 4 is the final stage involving the medial side (medial malleolus fracture or deltoid
ligament rupture).
2. What is the normal range for Bohler’s angle on a lateral foot radiograph?
A. 5 to 15 degrees
B. 60 to 75 degrees
C. 45 to 60 degrees
D. 25 to 40 degrees
,Answer: D
Conceptual Explanation: Bohler’s angle is formed by the intersection of two lines on a
lateral radiograph of the calcaneus; a normal range is 25 to 40 degrees. A decrease suggests
a calcaneal compression fracture.
3. Which organism is most commonly associated with osteomyelitis following a puncture
wound through a rubber-soled shoe?
A. Staphylococcus aureus
B. Pseudomonas aeruginosa
C. Streptococcus pyogenes
D. Escherichia coli
Answer: B
Conceptual Explanation: Pseudomonas aeruginosa is notoriously associated with
puncture wounds through rubber-soled shoes because the organism thrives in the moist
environment of the foam/rubber padding.
4. In a Hawkins Type II talar neck fracture, what is the approximate reported risk of avascular
necrosis (AVN)?
A. 0-15%
B. 20-50%
C. 80-90%
, D. 100%
Answer: B
Conceptual Explanation: Hawkins Type II fractures involve a talar neck fracture with
subluxation or dislocation of the subtalar joint, typically resulting in an AVN risk of 20-
50%.
5. Which of the following tests is most specific for diagnosing a rupture of the Achilles
tendon?
A. Lachman test
B. Mulder’s click
C. Thompson test
D. Silfverskiold test
Answer: C
Conceptual Explanation: The Thompson test (calf squeeze test) is the clinical gold
standard for identifying a complete rupture of the Achilles tendon.
6. What is the most common site for a tarsal coalition?
A. Talonavicular and Calcaneocuboid
B. Naviculocuneiform and Metatarsocuneiform
C. Taloncalcaneal and Calcaneonavicular
D. Cubocuneiform and Astragalonavicular
