The distal radioulnar joint is located between the radius and the ulna at the wrist. All the movements of the wrist are performed by the muscles of the forearm. Formed by the head of the ulna and the ulnar notch of the radius, this joint is separated from the radiocarpal joint by an articular disk lying between the radius and the styloid process of the ulna. The lunate is forced anteriorly, and compresses the carpal tunnel, causing the symptoms of carpal tunnel syndrome. There are four ligaments of note in the wrist joint, one for each side of the joint. The wrist joint (also known as the radiocarpal joint) is a synovial joint in the upper limb, marking the area of transition between the forearm and the hand. Proximally – The distal end of the radius, and the articular disk (see below). Anterior and posterior ligaments support the joint (in other words, these ligaments are close to the front and to the back of the wrist, respectively). Some of your joints are called ball and socket joints because, like with the hip, the ball of the hip fits into the socket, and allows you to swing your leg. The third functional class of joints is the freely movable diarthrosis joints.

The capsule of the joint is lax and extends from the inferior sacciform recess to the ulnar shaft. The scaphoid bone of the hand is the most commonly fractured carpal bone – typically by falling on an oustretched hand (FOOSH). The synovial joints are characterized by the presence of synovial fluid within a space that encapsulates the articulating surfaces (surfaces that touch each other) of the joint. You get flexion, extension, abduction, adduction and you get circumduction, which is a combination of all these movements. What type of joint is the wrist? This means that a fracture to the middle (or ‘waist’) of the scaphoid may interrupt the blood supply to the proximal part of the scaphoid bone rendering it avascular. The carpal tunnel is bounded by the carpal bones deeply, thus forming its floor, and the flexor retinaculum superficially, forming its roof. Wrist ligaments are best assessed with dedicated wrist MRI. This website uses cookies to improve your experience while you navigate through the website.
