There were fixed flexion deformities of the interphalangeal joints of both thumbs and fifth fingers, and webbing between each thumb and the forefinger.
Three-dimensional kinematics of the proximal interphalangeal joint: effects of raising the heels or the toe.
In this case the mean value of the human distal interphalangeal joint and the proximal interphalangeal joint is mapped to the distal joint of the robot hand.
The joint in the middle of the finger (proximal interphalangeal joint) and the one that is at the end of the finger (distal interphalangeal joint) are coupled.
When the palms of both hands are confronted, flexion contracture of the interphalangeal joint is evident in both thumbs and in the third finger of the upper hand.
The first two digits have interphalangeal joints that allow the digits to flex in to the palm as well as to open wide enough to admit large objects.
The articulations are: interphalangeal articulations between phalangeal bones, and metacarpophalangeal joints connecting the phalanges to the metacarpal bones.
The best examples of ginglymus are the interphalangeal joints and the joint between the humerus and ulna.
