1. According to the Hawkins classification of talar neck fractures, which type involves a
subluxation or dislocation of both the subtalar joint and the tibiotalar joint?
A. Type I
B. Type II
C. Type III
D. Type IV
Answer: C
Conceptual Explanation: Hawkins Type III is defined by a talar neck fracture with
dislocation of both the subtalar and ankle (tibiotalar) joints. Type IV adds the talonavicular
joint.
,2. What is the reported incidence of avascular necrosis (AVN) in a Hawkins Type IV talar neck
fracture?
A. 0-15%
B. 25-50%
C. 75-90%
D. 接近100%
Answer: D
Conceptual Explanation: Hawkins Type IV fractures have an AVN rate approaching 100%
due to the disruption of all three major blood supply routes (sinus tarsi, tarsal canal, and
deltoid branches).
3. In the Lauge-Hansen classification, what is the sequence of injuries for a Supination-
External Rotation (SER) injury?
A. AITFL rupture, fibula fracture (spiral), PITFL rupture, medial malleolus fracture
B. Medial malleolus fracture, AITFL rupture, fibula fracture, PITFL rupture
C. AITFL rupture, PITFL rupture, fibula fracture, medial malleolus fracture
D. Fibula fracture, AITFL rupture, PITFL rupture, medial malleolus fracture
Answer: A
, Conceptual Explanation: SER sequence: 1. Anterior-inferior tibiofibular ligament (AITFL)
rupture; 2. Spiral fibular fracture; 3. Posterior-inferior tibiofibular ligament (PITFL) or
posterior malleolus; 4. Medial malleolus or deltoid ligament.
4. Which Sanders classification type describes a calcaneal fracture with three articular
fragments in the posterior facet, specifically with lines through the primary and
central/lateral aspects?
A. Type IIIAB
B. Type IIA
C. Type IIB
D. Type IIIBC
Answer: A
Conceptual Explanation: Sanders Type III fractures involve two fracture lines and three
fragments. Type IIIAB involves fractures through the lateral (A) and central (B) columns.
5. A ‘Snowboarder’s fracture’ refers to which specific injury?
A. Fracture of the posterior process of the talus
B. Fracture of the lateral process of the talus
C. Spiral fracture of the 5th metatarsal
D. Anterior process calcaneal fracture
Answer: B
