Normal values for trabecular and cortical bone in the radius measured by computed tomography.
Quantities related to the amount of trabecular bone in the distal radius and cortical bone in the radius mid-shaft have been measured in 262 normal adults of both sexes aged 21-89 years by computed tomography (CT). A special-purpose CT system (ISOTOM) which incorporated a source of 125I (29 keV) was used to make the measurements. The relationships between these quantities and age, weight, height and surface area have been evaluated, and the results have been used to draw conclusions on the significance of values measured in female patients with osteoporosis, Colles' fracture of the wrist and generalised osteoarthritis.
