Bone density of the lumbar spine was measured in 712 male and female subjects ranging in age between 16 and 96 years at 11 medical instructions all over Japan, to establish normative values for each age and sex group. The peak bone mass of 0.75 g/cm2 was reached in the 30s in males and that of 0.76 g/cm2 in the 40s in females. The lumbar spine density obtained by this method showed good parallelism with the Singh index and degree of lumbar spine bone loss according to Jikei University method. A high correlation was also found between the bone density obtained by this method and that obtained by Lunar DP-4 (r=0.902, n=28). Spinal compression fracture was found in about 2/3 of the subjects with L2 - L4 bone density measured in the anterior-posterior direction of less than 0.58 g/cm2 and 3/4 of those with the corresponding value less than 0.49 g/cm2. Bone density less than 0.49 g/cm2 was therefore tentatively called the range predicting fracture (dangerous range) and that between 0.49 and 0.58 as the range warning fracture (warning range).
