The authors describe the case of an athlete from the Brazilian national men's basketball team (sub-16) who reported pain in the right iliac region at the end of the season. Clinical and imaging exams revealed an iliac bone stress fracture. A conservative treatment of removing the load from the fracture in combination with physical therapy was chosen. The athlete improved satisfactorily and returned to the sport at the same level as prior to the injury after 14 weeks of treatment.
