Abstract

The relationship between long-term bisphosphonate usage and insufficiency fracture in osteoporotic elderly patients has been increased interest in recent years. Most reported insufficiency fractures are predominantly concentrated on proximal femoral shaft or pelvic bone. However, there was no report about insufficiency femoral neck fracture after long term use of bisphosphonate in domestic. We experienced a rare case of a 70-years-old woman who was diagnosed with bilateral insufficiency femoral neck fracture after 8 years use of alendronate. We performed an internal fixation using 6.5 mm diameter cannulated screws for the both insufficiency femoral neck fracture. Symptoms disappeared immediately after the surgery and there was no radiologic and clinical complication such as nonunion or delayed union up to the latest follow-up at 12 months postoperatively.
