The hamate bone is a small wrist (carpal) bone located on the ulnar side of your hand—that’s the same side as your ring and little fingers.

Quick Scoop: Where it is

  • It sits in the distal row of the carpal bones, closer to your fingers than to your forearm.
  • It is the most medial bone of that row, meaning it’s on the inner side of the wrist toward the little finger.
  • It lies:
    • Proximal (just above) the bases of the 4th and 5th metacarpal bones (ring and little fingers).
* Distal (just below) the lunate bone.

* Medial (toward the little finger) to the capitate bone.

* Lateral (toward the thumb) to the triquetrum bone.

A key landmark is its hook-shaped projection (the “hook of hamate”) on the palm side of the wrist, which helps form the borders of the carpal tunnel and Guyon’s canal.

TL;DR: The hamate bone is a wedge-shaped carpal bone in the distal row of your wrist, on the little-finger side, just above the bases of the ring and little finger bones, with a distinctive hook on the palm side.
