| Research Abstract |
We assessed which part of the femoral head was the key point of a collapse, and also examined whether a collapsed region was associated with the size of necrotic lesion. Then, the results suggested that a collapse may begin at the lateral boundary of the necrotic lesion, and the size of the necrotic lesion seemed to contribute to the distribution of a collapse. We also examined the reparative process of osteonecrosis using SPECT/CT with 99mTc methylene diphosphonate. Then, during the time before collapse, there was a gradual increase in the tracer uptake around the necrotic lesion, shifting the main region from anteriorly to laterally.
