Hamate (left) (Os hamatum)
Educational content only — not medical advice.
Anatomy
A distal-row carpal whose hook (hamulus) projects to the palm; the ulnar nerve crosses in front of it in Guyon canal, the little-finger flexors sling from it, and it bounds the ulnar side of the carpal tunnel. This is the left member of the pair.
Clinical notes
Hook fracture is notorious among golfers and tennis players from the grip; palmar pain overlaps ulnar-nerve symptoms because the adjacent canal runs beneath the hook.
