The palmar ulnocarpal ligament is a ligament of the radiocarpal joint. It consists of ulnolunate, ulnocapitate, and ulnotriquetal ligaments. [2]

The palmar ulnocarpal ligament is a strong, fibrous structure composed of multiple bundles of fibers, including the ulnocapitate, ulnolunate, ulnotriquetral, and ulnopisiform ligaments. The fibers of these ligaments are often confluent and indistinguishable from each other (Moritomo, 2013).

The ulnotriquetral, ulnocapitate, and ulnolunate ligaments originate together at the fovea of the ulnar head and the base of the ulnar styloid. These ligaments, along with the palmar radioulnar (RU) ligament, extend distally like a fan in the coronal plane and insert at the palmar aspects of the triquetrum, capitate, and lunate (Figs. 1, 2 ...

2024年3月7日 · the most important intrinsic ligaments are the scapholunate interosseous ligament and lunotriquetral interosseous ligament

2023年10月30日 · The palmar ulnocarpal ligament arises from the anterior margin of the triangular fibrocartilage complex, the palmar radioulnar ligament and ulnar styloid process. It divides into three parts and courses distally obliquely towards the capitate, lunate and triquetrum bones, forming the unlocapitate, ulnolunate and ulnotriquetral divisions ...

The primary palmar radiocarpal extrinsic ligaments are: radioscaphocapitate (RSC), long radiolunate (LRL), and short radiolunate (SRL) ligaments. The palmar ulnocarpal ligaments are the superficial ulnocapitate and the deeper ulnolunate and ulnotriquetral ligaments.

The palmar ulnocarpal ligament is a ligament of the wrist joint that attaches the styloid process of the ulna to the lunate and triquetral bones.

2023年11月9日 · The palmar ulnocarpal group of ligaments include the ulnotriquetral, ulnocapitate and ulnolunate ligaments. As implied by the nomenclature, these ligaments help to stabilize the triquetrum, lunate and capitate bones by anchoring them to the palmar region of the ulna.

The ulnocarpal complex (triangular fibrocartilage complex; TFCC) represents an intricate system of structures which secures motion guidance, stability and pressure transmission in the ulnocarpal compartment of the wrist joint. Anatomically, this complex consists of …

The ligaments of the wrist can be divided into extrinsic and intrinsic ligaments. The extrinsic ligaments connect the carpal bones to the radius or metacarpals. They can be further separated into volar (palmar) and dorsal ligaments.
