Abstract

Atypical femoral fractures (AFFs) typically present in patients predisposed to brittle bones or greater biomechanical stresses along the shaft of the femur. Risk factors include, Asian population, women, high body mass index, and users of bisphosphonates, glucocorticoids, and proton pump inhibitors. Most commonly the injury occurs in the proximal or middle portion, but few studies have documented distal femoral stress fractures.

This case illustrates a patient presenting with right lower extremity pain for over a month and difficulty ambulating for a few days. He initially had a negative conservative work up when the pain started. The patient lacked high energy trauma history and other predisposing conditions. After imaging with both X-ray and MRI, he was diagnosed with an occult transverse stress fracture of the distal femoral diametaphysis. He was treated conservatively with non-weight bearing to the right lower extremity for 6 weeks. On follow up, his fracture healed well and clinically the patient was able to return to his daily activities.

This report emphasizes a unique fracture mechanism and location to the limited evidence of AFFs. The case urges clinicians to consider ordering additional imaging for patients if the provider has a high clinical suspicion of fractures. A comprehensive history is warranted for the case of occult fractures as knowledge of risk factors can help diagnostic accuracy and improve patient care.
