Avulsion of the iliac crest cartilage is an infrequent, rarely described lesion. Young and adolescent athletes are prone to this lesion. Indirect trauma caused by contraction of the muscles inserted at the iliac crest and the angulation move-ment of the trunk in direction opposite to the contraction is the most common mechanism causing cartilage tearing. As most of the cases do not present direct trauma, diagnosis can be missed if that possibility is not considered. Two cases attended by our Service are described. Lesion in the cartilage was observed due to an indirect trauma (abrupt muscular contraction). Both cases were treated and the evoluti-on was excellent.
