Femoral neck stress fractures in children and adolescents.

Abstract

Five new cases of femoral neck stress fracture in children and adolescents are added to seven cases in the literature. All patients were involved in increased repetitive activity without evidence of violent trauma. Most fractures healed uneventfully with appropriate treatment. However, increased morbidity from displacement of the fracture, delayed union, nonunion, or avascular necrosis does occur in this age group and needs to be avoided. A delayed union healed after treatment in a spica cast; a nonunion and a displaced fracture healed after internal fixation. All patients returned to their previous level of activity. Our treatment algorithm addresses the unique differences associated with this injury in immature patients and allows for early diagnosis and treatment to prevent complications.
