What pathologic condition might stress images of the ankle evaluate?

Stress imaging of the ankle is specifically designed to assess the integrity of the ankle joint and its stabilizing structures under load. Inversion and eversion injuries can result from excessive lateral or medial forces applied during activities, leading to ligamentous strain or tearing. Stress images help visualize how the ligaments respond to these forces, revealing potential injuries that may not be apparent on standard X-rays. This imaging technique is particularly useful for diagnosing instability and assessing the extent of soft tissue damage, making it an effective method for evaluating inversion and eversion injuries of the ankle.

While fractures, arthritis, and sprains can also be evaluated through various imaging techniques, stress imaging is primarily targeted at identifying issues related to excessive motion caused by inversion or eversion, hence its specific relevance to those types of injuries.
