Avascular necrosis and its relation to lipid and purine metabolism.

Serum uric acid, triglycerides, cholesterol, and lipoprotein levels were determined in 35 patients with primary avascular necrosis of the femoral head. The results were compared with a control group and a group of gouty patients. Frequency distribution of the data in the three groups was found to be of the log normal type, and the statistical calculations were performed after log transformation of the serum values.
