The lunate bone (semilunar bone) is a carpal bone in the human hand. It is distinguished by its deep concavity and crescentic outline. It is situated in the center of the proximal row carpal bones, which lie between the ulna and radius and the hand. The lunate carpal bone is situated between the lateral scaphoid bone and medial triquetral bone.

[5] Increased AP distance indicates the lunate facet fracture. [8]

The two medial fragments (which together create the lunate fossa) are grouped together as the medial complex. [8]
