Changes in structure of bone in these patients included two types: bone oxalosis and renal osteodystrophia.   Case report : The patient was a child aged 10 years old under dialysis due to renal failure. He had a fracture of femoral neck and two times subtrochanteric fracture. Conclusion: One of the most places for fracture in these patients is proximal of femur.
