Use of 18F and a scintillation positron camera permitted the detection of radioactivity in the femoral head of dogs. Absence of 18F correlated with avascularity and the presence of 18F with vascularity of the femoral head. The findings were documented by histological and tetracycline labeling techniques. Revascularization of the femoral head was detected as early as 1 mth after surgically induced avascularity. Preliminary studies in patients support these observations. The results of this investigation suggest that this radioisotopic technique may prove to be a practical method of assessing femoral head circulation and predicting avascular necrosis of the femoral head. Early diagnosis of avascularity of the femoral head following femoral head fracture could significantly reduce the morbidity of this disease.
