The dorsal radiocarpal ligament (posterior ligament) is less thick and strong than its volar counterpart, and has a proximal attachment to the posterior border of the distal radius. Its fibers run medially and inferiorly to form a distal attachment at the dorsal surfaces of the scaphoid (navicular bone of the hand), lunate , and triquetral .
The palmar intercarpal ligaments are also two, connect the scaphoid and lunate, and the lunate and triangular; they are less strong than the dorsal, and placed very deeply behind the Flexor tendons and the volar radiocarpal ligament. The interosseous intercarpal ligaments are two narrow bundles, one connecting the lunate with the scaphoid, the ...
The dorsal surface is rough for the attachment of ligaments. The volar surface presents, on its medial part, an oval facet, for articulation with the pisiform; its lateral part is rough for ligamentous attachment. The lateral surface, the base of the pyramid, is marked by a flat, quadrilateral facet, for articulation with the lunate.
The traditional portals are at the back of the hand (dorsal side), because many neurovascular structures are at risk at the palmar side of the hand. Table 1. Different portals that can be used during Wrist Arthroscopy [16] Dorsal Radial portals The portals lay between the dorsal extensor compartments. [17] 1-2 portal:
The radius is part of two joints: the elbow and the wrist. At the elbow, it joins with the capitulum of the humerus, and in a separate region, with the ulna at the radial notch. At the wrist, the radius forms a joint with the ulna bone. The corresponding bone in the lower leg is the tibia.
Radiocarpal ligament can refer to: Dorsal radiocarpal ligament (ligamentum radiocarpale dorsale) Palmar radiocarpal ligament (ligamentum radiocarpale palmare)
Open surgery is usually required for degenerative or more complex TFCC injuries, or if additional damage to the wrist or forearm caused instability or displacement. It is a more invasive surgical technique compared to arthroscopic treatment, but the surgeon has better visibility and access to the TFCC.
Dorsal ligament can refer to: Dorsal radioulnar ligament; Dorsal radiocarpal ligament; Dorsal cuboideonavicular ligament; Dorsal intercarpal ligament; Dorsal intercuneiform ligaments; Dorsal tarsometatarsal ligaments; Dorsal metatarsal ligaments
