Femoral neck stress fracture in a young female recruit: case report

Abstract

INTRODUCTION Femoral neck stress fractures are uncommon and depending on their location, can be at high risk for non-union and significant morbidity. Their prevalence is higher among runners and military recruits, and women seem to be at higher risk. METHODS A 27-year-old female, who was enrolled in military recruit, reported left side groin pain after a strenuous running exercise. Due to persistent pain an X-Ray was ordered, which revealed no signs of acute lesions. Further imaging studies with CT scan and MRI identified a compression-type femoral neck stress fracture. RESULTS The patient was submitted to conservative treatment consisting of restricting from full weight-bearing. Six weeks after she initiated partial weight-bearing, becoming asymptomatic at seven months. Follow-up imaging studies revealed union of the fracture. DISCUSSION This diagnosis should be considered when evaluating military and athlete populations. Early recognition of these injuries is crucial because complication and morbidity rates are high.
