A 74-year-old woman reported chronic thigh pain for 1 month. She had a history of an osteoporotic stable intertrochanteric fracture that was successfully treated with a short intramedullary nail 3.5 years prior. However, after union, the neck-shaft angle of the femur changed from 125\u00b0 to 117\u00b0. She had been on alendronic acid therapy to prevent a secondary osteoporotic fracture. A recent radiograph and bone scan suggested an insufficiency fracture around the level of the distal interlocking screw. Revision surgery with a long intramedullary nail was performed, and complete union was observed 1 year postoperatively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>This case suggests that subsequent insufficiency fracture can occur after complete union of an intertrochanteric hip fracture.
