What does the talotibial joint swing test assess?

• A. Assesses any restriction in talus motion relative to the tibia
• B. Measures dorsiflexion range of the ankle
• C. Tests for spring ligament integrity
• D. Evaluates subtalar joint inversion

Answer: (A)

The test is about how freely the talus moves inside the tibial mortise. By gently swinging or oscillating the talus against the tibia, you’re checking for any restriction in talus motion relative to the tibia. If motion is limited, it points to capsular or ligamentous tightness or articular restriction at the talotibial joint. It’s not a measure of overall dorsiflexion range at the ankle (that looks at the talocrural joint’s motion in a different way), nor a test of the spring ligament, nor an assessment of subtalar joint inversion. So the key idea is evaluating how freely the talus moves relative to the tibia.
