Upper Extremity Joints
Joints of the Hand
When Hand and Wrist Specialists refer to hand joints, they talk about the palmar or volar surface (the palm side of the hand), the dorsal surface (the back side), the radial side (toward the thumbs), and the ulnar side (toward the little fingers). The joints in the hands contain cartilage surfaces at the ends of the bones. Cartilage allows for smooth surface gliding.
