RESUMEN
Iatrogenic fracture is not popular and might be recognized as a malpractice. Surgical error related to iatrogenic fracture which has occurred after an operation can be detected only by a surgeon. Stress riser fracture is another form of iatrogenic fracture also known as a Young's modulus fracture. As the majority of surgical related stress riser fractures can be preventive, the accurate prevalence is not known. The majority of fractures occurred in the weight bearing bones such as femur and tibia. The subtrochanter area is the most stress concentrated area in the human body, thus it is a common area for occurrence of stress riser iatrogenic fractures. We experienced 2 cases of stress riser iatrogenic fractures, which are related to technical errors, thus we report cases with literature review.
