Wrist and hand

Triquetrum

Os triquetrum

How to find it
Move half a centimetre distal and slightly palmar from the ulnar styloid. On radial deviation of the wrist the bone comes out under your finger.
What you use it for
With the pisiform it forms the ulnar cornerstone of the wrist. Tenderness here belongs to the examination of ulnar-sided wrist complaints, alongside the TFCC.
