My son age 15 fractured his left ilium..uring a lacrosse game...the very tip of the wing broke off and with that his ligament tore..we went to a ortho?

Apophysis-sartorious: Rest, ice, and decreased activity is the usual treatment of choice for injury to the iliac crest. The growth plate is likely just about to close via the apophysis. This is where several muscle take their origin. In your son's case, it is likely an apophyseal fracture, minimally displaced, and amenable to nonoperative treatment
