Effect of cross-sectional imaging on negative appendectomy and perforation rates in children.

abstract：:Ankle trauma commonly results in significant injury. Knowledge of the anatomy of the normally nonopaque major supportive ligaments, and their relationships to the osseous structures seen on standard roentgenograms, facilitates interpretation of both plain films and ankle arthrograms. A group of normal, non-preserved a...
