Normal values for trabecular and cortical bone in the radius measured by computed tomography

Area of Science:

• Radiology
• Orthopedics
• Gerontology

Background:

• Bone density measurements are crucial for diagnosing conditions like osteoporosis.
• Understanding age-related bone changes is essential for clinical practice.
• Trabecular and cortical bone quantification provides insights into bone health.

Purpose of the Study:

• To measure trabecular and cortical bone in the radius of healthy adults.
• To evaluate the relationship between bone quantities and demographic factors (age, weight, height).
• To establish reference values for interpreting bone density in specific patient groups.

Main Methods:

• Utilized a specialized computed tomography (CT) system (ISOTOM) with an iodine-125 source.
• Quantified trabecular bone in the distal radius and cortical bone in the radius mid-shaft.
• Analyzed data from 262 normal adults across a wide age range (21-89 years).

Main Results:

• Established normative data for trabecular and cortical bone in the radius.
• Demonstrated correlations between bone quantities and age, weight, height, and body surface area.
• Provided a basis for comparing patient bone density to healthy individuals.

Conclusions:

• The study provides essential reference data for bone density assessment in the radius.
• Findings aid in the interpretation of bone measurements in women with osteoporosis and wrist fractures.
• Results contribute to understanding bone changes in osteoarthritis and related conditions.
