Subtrochanteric Femoral Fracture in a Patient on Alendronate Therapy: A Case Report

Bisphosphonates are currently widely used in the treatment of osteoporosis. Recent reports have attributed atypical femoral fractures to long term use of bisphosphonates. We present a case of such a low energy subtrochanteric femur fracture in a lady who was on alendronate therapy for three years. Radiological evaluation revealed features similar to those found in other reported cases, demonstrating that this fracture could have been predicted if the patient was closely monitored.
