Arthrokinematic Laws. • The elbow joint is considered to be a complexed joint that functions as a modified or loose hinge joint. Limits motion of elbow to flexion and extension. Boutonniere deformity is a deformed position of the fingers or toes, in which the joint nearest the knuckle (the proximal interphalangeal joint, or PIP) is permanently bent toward the palm while the farthest joint (the distal interphalangeal joint, or DIP) is bent back away. When the concave surface is fixed and the convex surface moves on it, the convex surface rolls and glides in opposite directions.
