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 articular capsule of the knee joint is the wide and lax joint capsule of the knee. It is thin in front and at the side, and contains the patella, ligaments, menisci, and bursae of the knee. [1] The capsule consists of an inner synovial membrane, and an outer fibrous membrane separated by fatty deposits anteriorly and posteriorly. [2]
A meniscus (pl.: menisci or meniscuses) is a crescent-shaped fibrocartilaginous anatomical structure that, in contrast to an articular disc, only partly divides a joint cavity. [1] In humans, they are present in the knee, wrist, acromioclavicular, sternoclavicular, and temporomandibular joints; [2] in other animals they may be present in other ...
Radiocarpal ligament can refer to: Dorsal radiocarpal ligament (ligamentum radiocarpale dorsale) Palmar radiocarpal ligament (ligamentum radiocarpale palmare)
The joints of the proximal row are arthrodial joints, The scaphoid, lunate, and triquetrum are connected by dorsal, volar, and interosseous ligaments. The dorsal intercarpal ligament are two in number and placed transversely behind the bones of the first row; they connect the scaphoid and lunate, and the lunate and triquetrum.
There are four groups of ligaments in the region of the wrist: [8] The ligaments of the wrist proper which unite the ulna and radius with the carpus: the ulnar and radial collateral ligaments; the palmar and dorsal radiocarpal ligaments; and the palmar ulnocarpal ligament. (Shown in blue in the figure.)
During supination, the superficial palmar and the deep dorsal ligaments are tightened, [citation needed] preventing palmar translation of the ulna. In pronation, this is reversed: the superficial dorsal and the deep palmar ligaments are tightened and prevent dorsal translation of the ulna. [citation needed]
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
