In performing anterior talus HVLA, what is the thrust technique primarily described as?

• A. Plantarfexion with compression
• B. Dorsiflexion with traction and a high-velocity thrust
• C. Eversion with rotation
• D. Inversion with distraction

Answer: (B)

An anterior talus HVLA uses a rapid, high-velocity impulse delivered with the ankle in dorsiflexion and a small amount of traction to open the joint surfaces. This positioning facilitates an anterior glide of the talus within the ankle mortise, and the quick thrust provides the necessary force to overcome the joint resistance in a controlled, low-amplitude motion. The dorsiflexed position is essential because it brings the talus into a position where moving it forward is feasible, while traction ensures there’s enough space for the adjustment. Other vectors described in the choices do not capture the characteristic anterior glide combined with dorsiflexion and a rapid impulse.
