We are going to report three insufficiency fracture cases which are considered to be caused by osteoporosis, rheumatoid arthritis, steroid use and femoral shaft bowing among the patients not taking bisphosphonate. All cases are caused by low energy trauma and among these cases, one patient is being presented with a prodromal symptom and another patient complains of both prodromal symptoms and bilateral lesions.
