Abstract
The osteopetrosis is characterized by the osteosclerosis of the whole body and is a rare disease. We reported a case of subtrochanteric fracture of the femur accompanied by osteopetrosis on a female aged 62.
When operating, we had difficulty in drilling and tapping because the bone was very hard. Moreover, the cancellous bone was hardly able to be gathered from the iliac bone though the bone graft was done. We had another operation in seven months after the first operation because the fracture part had become a pseudoarthrosis.
The patient is not obtaining the bone union and are kept under observation.
