Q1. Which structure forms the primary weight-bearing surface of the heel?
A. Calcaneal fat pad
B. Plantar fascia
C. Achilles tendon
D. Flexor hallucis longus tendon
Correct Answer: A
Rationale: The calcaneal fat pad is a specialized adipose structure that absorbs shock and
distributes weight during heel strike. Option B is incorrect because the plantar fascia supports the
arch but is not the primary weight-bearing surface. Option C is wrong because the Achilles tendon
transmits force from the calf muscles to the calcaneus. Option D is incorrect because the flexor
hallucis longus tendon flexes the great toe and does not bear weight. Understanding the anatomy of
the heel is essential for diagnosing heel pain and pressure-related pathologies.
Q2. Which bone is the keystone of the medial longitudinal arch?
,A. Navicular
B. Calcaneus
C. Talus
D. First metatarsal
Correct Answer: A
Rationale: The navicular bone is considered the keystone of the medial longitudinal arch
because it receives support from the posterior tibial tendon and maintains arch height. Option B is
incorrect because the calcaneus forms the posterior foundation of the arch. Option C is wrong
because the talus transmits body weight to the foot but does not serve as the arch keystone. Option
D is incorrect because the first metatarsal supports the anterior arch but is not the keystone.
Recognizing the navicular's role is critical for evaluating flatfoot deformity.
Q3. Which muscle is the primary invertor of the foot?
A. Tibialis posterior
B. Peroneus longus
C. Peroneus brevis
D. Extensor digitorum longus
Correct Answer: A
Rationale: The tibialis posterior is the primary invertor of the foot and also supports the
medial longitudinal arch during gait. Option B is incorrect because the peroneus longus everts the
foot. Option C is wrong because the peroneus brevis also everts the foot. Option D is incorrect
because the extensor digitorum longus dorsiflexes the toes and assists with dorsiflexion.
Understanding muscle function is essential for diagnosing tendon dysfunction and prescribing
orthotics.
Q4. Which ligament is most commonly injured in an ankle inversion sprain?
A. Anterior talofibular ligament
B. Calcaneofibular ligament
C. Posterior talofibular ligament
D. Deltoid ligament
Correct Answer: A
Rationale: The anterior talofibular ligament is the most commonly injured ligament in ankle
inversion sprains because it is the weakest and most anteriorly located lateral ligament. Option B is
incorrect because the calcaneofibular ligament is injured in more severe sprains. Option C is wrong
,because the posterior talofibular ligament is rarely injured. Option D is incorrect because the deltoid
ligament is injured in eversion sprains. Recognizing the mechanism of injury guides appropriate
treatment and rehabilitation.
Q5. What is the normal range of ankle dorsiflexion during gait?
A. 5 degrees
B. 10 degrees
C. 15 degrees
D. 20 degrees
Correct Answer: B
Rationale: Normal ankle dorsiflexion required during gait is approximately 10 degrees, which
allows the tibia to advance over the planted foot. Option A is incorrect because 5 degrees is
insufficient for normal gait and suggests equinus. Option C is wrong because 15 degrees exceeds
normal requirements and may indicate hypermobility. Option D is incorrect because 20 degrees is
well above normal. Assessing dorsiflexion is critical for diagnosing equinus deformity and planning
treatment.
Q6. Which structure is the primary dynamic stabilizer of the medial longitudinal arch?
A. Posterior tibial tendon
B. Plantar fascia
C. Spring ligament
D. Deltoid ligament
Correct Answer: A
Rationale: The posterior tibial tendon is the primary dynamic stabilizer of the medial
longitudinal arch, providing active support during weight-bearing. Option B is incorrect because the
plantar fascia provides passive support. Option C is wrong because the spring ligament provides
static support. Option D is incorrect because the deltoid ligament stabilizes the ankle medially.
Posterior tibial tendon dysfunction is a common cause of adult-acquired flatfoot.
Q7. Which metatarsal is most commonly fractured in a Jones fracture?
A. First metatarsal
B. Second metatarsal
C. Fifth metatarsal
D. Third metatarsal
, Correct Answer: C
Rationale: A Jones fracture occurs at the proximal metaphyseal-diaphyseal junction of the fifth
metatarsal and is prone to nonunion due to poor blood supply. Option A is incorrect because first
metatarsal fractures are less common. Option B is wrong because second metatarsal fractures are
stress fractures. Option D is incorrect because third metatarsal fractures are rare. Recognizing the
location of a Jones fracture is essential for determining treatment and prognosis.
Q8. What is the primary function of the plantar fascia?
A. Support the medial longitudinal arch
B. Dorsiflex the ankle
C. Evert the foot
D. Flex the toes
Correct Answer: A
Rationale: The plantar fascia supports the medial longitudinal arch by acting as a tension band
during weight-bearing and gait. Option B is incorrect because dorsiflexion is performed by the tibialis
anterior. Option C is wrong because eversion is performed by the peroneal muscles. Option D is
incorrect because toe flexion is performed by the flexor muscles. Plantar fasciitis is a common cause
of heel pain due to repetitive strain.
Q9. Which nerve is most commonly affected in tarsal tunnel syndrome?
A. Tibial nerve
B. Sural nerve
C. Superficial peroneal nerve
D. Deep peroneal nerve
Correct Answer: A
Rationale: The tibial nerve is most commonly affected in tarsal tunnel syndrome as it passes
through the tarsal tunnel behind the medial malleolus. Option B is incorrect because the sural nerve
supplies the lateral foot and is not in the tarsal tunnel. Option C is wrong because the superficial
peroneal nerve supplies the dorsum of the foot. Option D is incorrect because the deep peroneal
nerve supplies the first web space. Recognizing nerve compression syndromes guides diagnosis and
treatment.
Q10. What is the normal angle of gait in adults?
A. 5 to 10 degrees
