During passive dorsiflexion at the talocrural joint, which structure primarily limits the motion?
Understand the Problem
The question is asking which anatomical structure primarily limits the motion during passive dorsiflexion at the talocrural joint, essentially testing knowledge of anatomy and biomechanics related to the ankle joint.
Answer
Calcaneofibular ligament.
The calcaneofibular ligament primarily limits motion during passive dorsiflexion at the talocrural joint.
Answer for screen readers
The calcaneofibular ligament primarily limits motion during passive dorsiflexion at the talocrural joint.
More Information
The calcaneofibular ligament is key for stabilizing the lateral aspect of the ankle, particularly limiting inversion and assisting in weight-bearing during dorsiflexion.
Tips
A common mistake is confusing the calcaneofibular ligament with the anterior talofibular ligament, which primarily restrains the ankle in different movements.
