Final answer:
The talar tilt test primarily assesses the integrity of the anterior talofibular ligament, which is the most commonly injured ligament during an inversion ankle sprain.
Step-by-step explanation:
The talar tilt test for inversion assesses the integrity of the ankle ligaments. Specifically, the anterior talofibular ligament (ATFL) is evaluated, as it is the most commonly injured ligament during an inversion ankle sprain. Following the ATFL, the calcaneofibular ligament (CFL) is also likely to be injured.
The talar tilt test involves passively inverting the ankle and assessing for excessive movement, which would suggest a sprain or tear of these ligaments, especially the ATFL. Ankle sprains are common injuries, particularly among athletes, and understanding the sequence of ligament involvement is crucial for accurate diagnosis and treatment.
