Names
- Volar Radiotriquetral Ligament
- Long Radiolunate Ligament
- Radiolunotriquetral Ligament
- Volar Radiolunate Ligament
General
- Large, intracapsular, extrinsic palmer radiocarpal ligament
- Palmer stabilizer of the wrist joint
Gross Anatomy
- Origin: palmar surface of the radial scaphoid fossa
- Insert: lunate, triquetrum

Ultrasound Features
- Transducer: volar aspect of radial side of wrist, slightly extended
- Start in longitudinal plane and rotate towards triquetrum
- Ligament appears as echogenic, fibrillary structure attaching distal radius to lunate, triquetrum[3]
