Recently, we discovered MRI changes in the femoral head after internal fixation for the femoral neck fractures at a stage of no abnormal findings of X-rays. Soon after operation, MRI findings in both cases were in-homogeneous patterns of almost the whole femoral head. A few months later, these findings changed to a small band pattern and in the subsequent long term, the small band pattern remained unchanged in the weight bearing area. These results may suggest that the in-homogeneous pattern means the femoral head healed somewhat after ischemic damage due to the fracture and the band pattern means the healing is interrupted and necrosis occurs.
