title: [Several aspects of osteoarticular aging of the hand].
abstract: The articular amplitudes (abduction of the thumb, flexion/extension of the digital joints), arthritic localizations and the mineralization of the bones of the hand were studied in 155 subjects of both genders and classified by decades from 20 to 90 or more years old. There was a significant decrease in articular amplitudes with age and a considerable increase of arthritis especially after 70 years. Arthritic changes were seen most frequently in the distal interphalangeal joints, then with an equal prevalence, arthritis was encountered in the metacarpophalangeal and in the proximal interphalangeal joints. Articular chondrocalcinosis had a prevalence of 15 p. cent in subjects over 60 years and was always associated with arthritic changes in subjects over 80. The cortical index of the second metacarpal bone, which was chosen to express osteopenia, diminishes significantly with age only in female subjects.
