Ligaments in your wrist include: Ulnocarpal and radiocarpal ligaments: Ligaments that stabilize your whole wrist while it moves. Collateral ligaments: These are the same ligaments as the ones in your hand. They run on both sides on the outside of your wrist and hold your wrist in place.
There are four main ligaments located at the wrist joint: Palmar radiocarpal – located on the palmar (anterior) side of the joint. It passes from the radius to both rows of carpal bones. Its function, apart from increasing stability, is to ensure that the hand follows the forearm during supination.
One of the most commonly fractured bones in this region is the distal radius and scaphoid, while the most commonly injured ligament/sprain is the scapholunate ligament that plays an important role in wrist stability.
intrinsic ligaments. originate and insert on carpal bones. the most important intrinsic ligaments are the scapholunate interosseous ligament and lunotriquetral interosseous ligament. Characteristics. volar ligaments are secondary stabilizers of the scaphoid. volar ligaments are stronger than dorsal ligaments.
The intrinsic and extrinsic wrist ligaments play a vital role in the stability of the wrist joint. There are numerous ligaments but included below are the most clinically significant. Wrist ligaments are best assessed with dedicated wrist MRI.
There are two collateral ligaments that connect the forearm to the wrist, one on each side of the wrist. As its name suggests, the ulnar collateral ligament (UCL) is on the ulnar side of the wrist. It crosses the ulnar edge (the side away from the thumb) of the wrist.
Moving back around to the palmar surface of the wrist, we identified the four ligaments which form the palmar ulnocarpal ligaments – the ulnocapitate ligament, the ulnolunate ligament, the ulnotriquetral ligament, and the ulnopisiform ligament.
Note that the ulna is not part of the wrist joint itself, as it articulates with the distal via the distal radioulnar joint (DRUJ). The four ligaments responsible for maintaining the stability of the joint are the palmar and dorsal radiocarpal ligaments and the ulnar and radial collateral ligaments. The palmar radiocarpal ligaments are the ...
Wrist motion is controlled by the ligaments and the proximal forearm muscles. This article discusses the key anatomical structures of the wrist which enable functional movement, including the bony structures, articulations, ligaments, muscles, nerves and the vascular supply.
Ligaments support the wrist by linking the bones that make up the joint. Description. Ligaments are strong, fibrous tissues that connect bones to other bones. The ligaments in the wrist help to keep the bones in proper position and stabilize the joint.
