We reports two cases of femoral stress fractures, one at femoral neck, the other at distal femur. Femoral stress fracture is not uncommon in reported literature, but most of reported cases limited in military recruits and athlethes. There are few reports about femoral stress fractures of civilians. Early dignosis is difficult because complaints are vague and poorly localized, so displacement occurs and misdiagnosis is made. The purpose of this report is to call attention to the importance of early diagnosis of stress fracture of the femur so that displacement and misdiagnosis, which may lead to prolonged in capacitation or to the necessity for surgical intervention, may be prevented.
