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

The term wrist is applied to the upper limb region formed by all the carpal bones. The hand connects with the forearm through the radiocarpal (wrist) joint. However, the articular complex of the wrist consists of the following joints: 🔸Radiocarpal (wrist) joint - ellipsoid (condyloid) joint formed between the radius and the lunate and scaphoid bones of the proximal carpal row. 🔸Midcarpal joint - series of plane (gliding) joints between the carpal bones of the proximal and distal rows. Overall,
