The anterior talofibular ligament (ATFL) is most taut and most commonly injured in which ankle position?
Answer: Plantar flexion and inversion
The ATFL is most taut in plantar flexion and is the primary restraint against inversion in this position, making it the most commonly injured ligament in lateral ankle sprains.
Which carpal bone is most commonly fractured?
Answer: Scaphoid
The scaphoid is the most commonly fractured carpal bone, typically from a fall on an outstretched hand. Its blood supply enters distally, making proximal pole fractures susceptible to avascular necrosis.
The iliotibial band is a thickening of which fascial structure?
Answer: Fascia lata
The IT band is a lateral thickening of the fascia lata, the deep fascia of the thigh, with contributions from the tensor fasciae latae and gluteus maximus muscles.
The medial longitudinal arch of the foot is primarily supported by which passive structure?
Answer: Spring (plantar calcaneonavicular) ligament
The spring ligament (plantar calcaneonavicular ligament) directly supports the head of the talus and is the primary passive stabilizer of the medial longitudinal arch.
During the Thomas test, a positive result (leg rising off the table) indicates tightness of which structure?
Answer: Hip flexor complex (iliopsoas or rectus femoris)
A positive Thomas test — where the tested leg rises off the table when the opposite hip is fully flexed — indicates hip flexor tightness, specifically the iliopsoas and/or rectus femoris.
The terrible triad knee injury involves which three structures?
Answer: ACL, MCL, and medial meniscus
The terrible triad (O'Donoghue triad) classically describes combined injury to the ACL, MCL, and medial meniscus, typically from a valgus-external rotation force.
