Bone mineral mass was measured in normal subjects and osteoporotic patients at two forearm sites (proximal and distal of the 8 mm site between the two forearm bones) by single photon absorptiometry and in the spine and whole body by dual photon absorptiometry. There were no signs of preferential low spinal bone mass in 28 patients with vertebral fractures. Their bone mass was at all sites 26% to 37% lower than the premenopausal mean value and 7% to 13% lower than in age-matched normal women. In 45 patients with forearm fractures bone reduction was also universal but only 3% to 6% lower than in healthy women of comparable age. The spinal bone mass in all the patients was significantly related to both forearm measurements with coefficients of correlation of 0.58-0.61 and s.e.e. of 18%. Compared to the premenopausal normal range the distal forearm site had a greater sensitivity in identifying patients with vertebral fractures than had the spinal measurement (chi-square test, p < 0.01). We thus conclude that patients with vertebral fractures have universal osteoporosis and that measurement of spinal BMC had no predictive advantages over that of the forearm bone mass for population studies. J NucÃ-Med 28:960-965,1987"one mass in young, healthy women in different regions is interrelated while the representati vity of local bone measurements has been questioned in elderly and osteoporotic women (1,2). Although studies indicate that the rate of trabecular bone loss exceeds the cortical loss in the first postmenopausal years (3,4), bone is lost from all parts of the skeleton (5). In elderly women, the reduction in bone mass is the same at central and peripheral measuring sites (6) and in osteoporotic pa tients with hip fracture it is uniformly low (6-8). Many factors influence the rate of bone loss. Some individuals will lose more than others at individual sites, and frac tures are likely to occur at sites with the lowest bone mass.The prevalence of fractures of the distal forearm and the spine increases rapidly a few years after the meno pause. It has been claimed that vertebral fractures are the result of a predominant loss of trabecular bone (8), and a preferential low spinal bone mass, estimated by

The relationship between physical fitness and bone mass in the femoral neck, lumbar spine, and forearm was studied in 84 normal women. Femoral neck and lumbar spine bone mineral density and forearm bone mineral content were estimated by absorptiometry. Fitness was quantitated from predicted maximal oxygen uptake. Femoral neck and lumbar bone mineral density were significantly correlated with fitness as well as age and weight.in the 46 postmenopausal'subjects, fitness was the only significant predictor of femoral neck bone mineral density, and both weight and fitness predicted the lumbar bone mineral density. These data represent the first demonstration of a correlation between physical fitness, and, by implication, habitual physical activity, and bone mass in the femoral neck; they also support the previous reported correlation between lumbar bone mass and physical activity. The data suggest that increased physical fitness may increase bone mass at the sites of clinically important fractures in osteoporosis.

“…Most previous studies of bone loss from the distal radius in patients with Colles' fracture scanned at sites proximal to the fracture site (3,4,(6)(7)(8)(9), where the bone is mainly cortical; at those sites bone mineral content was 5-7% below normal. The one exception was the study by Hesp et al (5) in which UDR-BMD was measured by a combined computed tomography/ single photon absorptiometry technique.…”

“…Much less is known about the extent of bone loss from the ultradistal radius (UDR),I i.e., the distal 3 cm of the radius, in women with type I osteoporosis and Colles' fracture or the relationship of loss at this site to loss in the vertebrae. Most densitometric measurements have been made proximal to the usual site of Colles' fracture, in a region containing 5-50% trabecular bone (3)(4)(5)(6)(7)(8)(9).…”

We measured bone mineral density (BMD) at the lumbar spine (LS-BMD) and ultradistal radius (UDR-BMD) in 42 postmenopausal normal women and in 108 postmenopausal osteoporotic women (55 with vertebral fracture, 34 with Colles' fracture, and 19 with both fractures). By receiver operating characteristic analysis, LS-BMD was better than UDR-BMD (P < 0.01) as an indicator of vertebral fracture; the converse was true for Colles' fracture (P < 0.01). Although UDR-BMD and LS-BMD were lower in each of the three fracture groups than in controls (P < 0.01), the pattern of bone loss differed (P < 0.001, analysis of variance): with vertebral fracture, LS-BMD decreased relatively more than UDR-BMD, with Colles' fracture, UDR-BMD decreased relatively more than LS-BMD; and with both fractures, decreases in LS-BMD and UDR-BMD were similar. We conclude that both types of fracture are caused by excessive bone loss but the difference in bone loss at the two sites is a major factor in determining which will fracture.
