WATSON / SCAPHOID SHIFT TEST FOR SL LIGAMENT RUPTURE OF THE WRIST The scapholunate ligament is a very strong ligament between the scaphoid and the lunate and important for the stability of the wrist. It can be injured by a fall or a sudden load on the wrist and can occur together with a distal radius or carpal bone fracture. When untreated, it can lead to a so-called DISI, which stands for dorsal intercalated segmental instability, which is a dissociation between the scaphoid and the lunate. Acc

Anatomy 101 – The Lunate Bone (Wrist) The lunate is one of the central carpal bones, sitting in the proximal row of the wrist between the scaphoid and triquetrum, and articulating with the radius. How do you locate it? Clinically, the lunate is found on the dorsal aspect of the wrist, in line with the third metacarpal, just distal to the radius. It becomes easier to palpate with the wrist in slight flexion. Because of its central position and loading role, the lunate is the most commonly disloca

Anatomy Focus: Locating the LUNATE Bone The lunate is a crescent-shaped carpal bone located in the proximal row of the wrist, between the scaphoid (laterally) and triquetrum (medially). You can palpate it just distal to Lister’s tubercle of the radius by flexing the wrist — it will often become more prominent. Clinically, the lunate is the most commonly dislocated carpal bone due to its central position and articulation with multiple bones. It’s also vulnerable to Kienböck’s disease — a conditio
