Stress fracture in general is a well-known condition that can be found commonly in healthy athletes and military personnel. These fractures occur due to bone fatigue in response to the repetitive stress of exercise. Although few reports on stress fractures among military personnel and active young athletes can be found in previous literature, we present this case report of a young military soldier that had a completely displaced neck of femur fracture with no functional limitation for seven days prior to seeking medical advice; the patient was operated on and followed for three years after and did not develop complications associated with this kind of fracture. A reduction of neck of femur fracture and fixation in valgus position to maintain good reduction with weight-bearing as done in our case have assisted in reducing avascular necrosis (AVN) risk despite the high displacement and delayed operative intervention due to the patient's late presentation.
