This condition affects adolescent boys twice as much as adolescent girls, typically affecting boys 13-15 y.o. and girls11-15 y.o. There is also a 30% chance of asynchronous bilateral involvement (Stasikelies PJ et al 1996). Young men that are overweight appear to be affected most.

Clinical signs and symptoms include complaints of groin pain, worse with weight bearing activities, limited IR, increased ER ROM, and obligatory abduction and ER during passive flexion (Drehmann sign) (Drehmann 1979). Trendelenberg tests is often positive.
