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.
