Computed axial tomography and Disulphine Blue in the evaluation of osteonecrosis of the femoral head.
Precise evaluation of bone loss and bone viability is necessary in order to select the most appropriate operation for patients with osteonecrosis of the femoral head. Bone destruction, and its exact location, can be assessed by computed axial tomography. The viability of remaining bone can be observed at operation by systemic vital staining with Disulphine Blue.
