Metacarpophalangeal and interphalangeal flexion of the thumb: influence of sex and age, relation to ligamentous injury.
The flexion of the metacarpophalangeal and interphalangeal joints of both thumbs of 101 normal controls and of 10 patients with ligamentous injuries was measured. There is a close correlation between dominant and nondominant thumbs. With advancing age mobility of both joints decreases significantly. Stiffer joints are more vulnerable to ligamentous injuries.
