Diagnosis of aseptic necrosis of the talus by bone scintigraphy. Case report.

Bone scintigraphy is a very useful technique for detection of aseptic necrosis. We have used this diagnostic tool in a patient to detect aseptic necrosis of the talus, a common complication stemming from foot injuries. The scintigraphic pattern is rather typical and antedates any other radiographic changes. This technique appears to be very useful for diagnosis and follow-up of aseptic necrosis occurring during talar injuries.
