What is a lunotriquetral liga?
lunotriquetral liga is one of several strips of connective tissue that connects the lunate and triquetral bones in the human hand. Two of the seven carpal bones grouped at the base of the hand just above the wrist, madness and triquetral are adjacent bones that are located near the ulna bone on the monument side of the hand. Together with the Scaphoid bone, these two bones form a proximal range of carpal bones or those that articulate with the forearm of the bones to form a wrist. Between madness and triquetral and running almost perpendicular to the forearms are lunotriquetral ligaments that fill the space between the side surface of the triquetral, the farthest of the two bones and the middle of the lunate.
Although the lunate and triquetral bones do not actually form a joint with ulna, the articulation between the bones of the proximal cardal series helps them to function as a unit. The articulating surfaces are smooth and four -sided and the jmasts between them, the intermediate joint, is an arthrodial or flat joint. Synovial joint, this articulation allows malThe degree of sliding bone movement around you.
Holding these intermediate articles together are three types of lunotriquetral ligament. Considered the strongest of the three, what connects madness and triquetral on their rear surfaces is the dorsal intermediate ligament that runs between two bones in the direction almost perpendicular to the forearms. A similar liga is also located between a lunate and a scaphoid bone.
On the front of these bones is a palm intermediate ligament that combines madness and triquetral bones on the opposite side of the back ligament, but which runs parallel to this lunotric ligament. Similarly, there is a palmar ligament between the lunate and the scaphoid bones.
runs between the lunate and the triquetral bones on their superior surfaces, the nearest wrist, is the third species of lunotriquetral ligament. Well -knownAbout interosseous intercarpal ligament, it is flushed with the highest aspects of these bones and exceeds the gap between the edges of the most adjacent to the wrist. It also travels perpendicular to the forearms and, as it runs in a direction that is parallel to the wrist hinge, this lunotriquetral ligament covers an area that articulates directly with the wrist joint.
