Sonographic appearance of side strain injury.

Objective: The purpose of this study was to evaluate the role of sonography in assessing side strain in athletes.

Conclusion: Sonography is a useful tool for imaging the lateral abdominal musculature in patients with side strain, which occurs as a result of tearing of the internal oblique muscle from the lower four ribs or costal cartilage. Sonographic findings can be used to confirm the diagnosis, localize the site, and assess the characteristics of a tear.
