What symptom indicates the presence of a posterior ankle impingement?

• A. Pain during forced dorsiflexion
• B. Swelling around the ankle joint
• C. Loss of range of motion
• D. Crepitus during movement

Answer: (A)

Pain during forced dorsiflexion is a hallmark symptom of posterior ankle impingement. This occurs when the structures at the back of the ankle, such as the posterior talofibular ligament or the bony prominence of the heel, become compressed or pinched during the dorsiflexion movement. As the foot is brought upward toward the shin, the posterior structures are stretched, and if there is an impingement, it can lead to localized pain. Other symptoms like swelling, loss of range of motion, or crepitus can be associated with various ankle conditions, but they are not specific indicators for posterior ankle impingement. Swelling may suggest inflammation or injury, loss of range of motion can occur in multiple ankle issues, and crepitus indicates joint dysfunction, which might not be exclusive to impingement. The specific pain during forced dorsiflexion directly points to the mechanics of posterior ankle impingement, making it a critical symptom to consider during assessment.
