Simultaneous bilateral femoral neck stress fractures in a young military cadet: a rare case report

Simultaneous bilateral femoral neck stress fracture in healthy young adult is one of the very rare clinical entities that an orthopedic surgeon may encounter once in lifetime. Bilateral femoral neck stress fractures have been very well documented in elderly and osteomalacia patients; however, its simultaneous occurrence in a healthy adult is challenging to diagnose and manage. This article describes a 34-year-old man a military personnel who sustained bilateral stress femoral neck fractures, during a routine training activity. The patient was come to our institution, and a full endocrine evaluation was performed and proved unremarkable. He underwent closed reduction and internal fixation of the fractures using cannulated screws on both the sides. At 1-year follow-up, the fractures went on to complete union. Despite strict non-weight-bearing instructions for initial 3-month period, patient bore weight on the limbs resulting in varus union on the left side. Our case emphasizes the significance of obtaining a complete and thorough medical history on physical examination and appropriately counseling patients regarding activity level even after successful fixation.
