Name

# 4th Metacarpal

Pronunciation

(meta-kar-pal)

Notes

The fourth metacarpal bone (os metacarpale IV; metacarpal bone of the ring finger) [Fig. 4] is shorter and smaller than the third. The base is small and quadrilateral; its superior surface presents two facets, a large one medially for articulation with the hamate, and a small one laterally for the capitate. On the radial side are two oval facets, for articulation with the third metacarpal; and on the ulnar side a single concave facet, for the fifth metacarpal.
