Sep 16, 2024 · The ulnar collateral ligament of the wrist is an extrinsic dorsal ulnocarpal ligament and functions as a part of the triangular fibrocartilage complex as an ulnar stabilizer of the wrist 1-3.

May 31, 2018 · Pain on the pinkie (ulnar) side of the wrist is very common. It can result from injury to any of those bones, joint cartilage, ligaments (elastic bands connecting the bones to each other), or tendons (string-like fibers connecting the muscles the bones).

The ulnar collateral ligament of the wrist joint forms a thickening of the articular capsule on the medial side of the wrist joint (Brown et al., 1998). It arises from the ulnar styloid process and extends distally to insert onto the proximal surface of …

Jan 3, 2025 · The Ulnar Collateral Ligament of the Wrist attaches the ulnar styloid process to the triquetrum, pisiform and flexor retinaculum and contributes to the TFCC stabilizers of the ulnar side of the wrist

Mar 31, 2023 · The ulna is prevented from articulating with the carpal bones by the presence of a fibrocartilaginous ligament, the articular disk. Instead, the ulna articulates with the radius just proximal to the wrist – at the distal radioulnar joint.

The ulnar collateral ligament (internal lateral ligament, ulnar carpal collateral ligament or ulnar collateral ligament of the wrist joint) is a rounded cord, attached above to the end of the styloid process of the ulna, and dividing below into two fasciculi, one of which is attached to the medial side of the triquetral bone, the other to the ...

Apr 25, 2013 · We have divided our discussion of pertinent ligaments of the wrist into several broad categories: the intrinsic ligaments, the volar extrinsic ligaments, the dorsal extrinsic ligaments, and the ligaments of the thumb.

Oct 30, 2023 · The ulnotriquetral division is sometimes also referred to as the ulnar collateral (carpal) ligament. Working together, these ligaments serve to prevent palmar translocation of the ulnar carpal bones and allow the hand to follow the radius in its movements.

The radial and ulnar collateral ligaments of the wrist are true ligaments and can be seen at the floor of the first and the sixth extensor compartments, respectively, using high-resolution US. Based on their anatomic location, they most likely provide static stability to the wrist joint.

The ulnar collateral ligament of the wrist joint (internal lateral ligament, ulnar carpal collateral ligament) is a rounded cord, attached above to the end of the styloid process of the ulna, and dividing below into two fasciculi, one of which is attached to the medial side of the triquetral bone, the other to the pisiform and flexor retinaculum.
