Hand surgeon Mark Yuhas, MD answers your questions about ulnar-sided wrist pain.
What does it mean to have “ulnar-sided” wrist pain?
Pain on the ulnar side of the wrist refers to pain in the region of the wrist on the “pinky side” of the wrist joint. The structures on the pinky side of the wrist make a complex interaction with bones, joints, ligaments, and tendons. They allow us to grip, twist the forearm and wrist, and move the wrist forward (flexion) and backward (extension). In the wrist, injury or wearing down of these structures may lead to pain or instability.
What are some causes of ulnar-sided wrist pain?
In a relatively small area on the ulnar side of the wrist, there are many different structures. The main structures that cause pain in this part of the wrist are ligaments (soft tissue that connects bone to bone), tendons (soft tissue that connects bone to muscle), bone, or cartilage (allow joints to move smoothly). Also on this side of the wrist is the triangular fibrocartilage complex (TFCC) which is a group of soft tissue structures that work together.
