How to Remember the Carpal Bones
Eight wrist bones in two rows. One mnemonic to memorize both rows in five minutes. Then flashcards to make it permanent.
The carpal bones are eight small bones arranged in two rows of four at the wrist. Every anatomy and medical student memorizes them; every one forgets them by second-year unless the memory is spaced. The classic mnemonic — 'Some Lovers Try Positions That They Can't Handle' — is one of the most-used in anatomy education because it works.
The mnemonic — both rows in one sentence
'Some Lovers Try Positions That They Can't Handle.'
- S — Scaphoid
- L — Lunate
- T — Triquetrum
- P — Pisiform
- T — Trapezium
- T — Trapezoid
- C — Capitate
- H — Hamate
The proximal vs distal split
Proximal row (closer to forearm): Scaphoid, Lunate, Triquetrum, Pisiform. Distal row (closer to fingers): Trapezium, Trapezoid, Capitate, Hamate. The mnemonic reads left-to-right lateral-to-medial.
Clinical high-yield
Scaphoid is the most commonly fractured carpal — the classic fall on outstretched hand. Blood supply is retrograde, so proximal-pole fractures risk avascular necrosis. Anatomical snuffbox tenderness = suspect scaphoid fracture.
Frequently asked questions
How is 'Trapezium' distinguished from 'Trapezoid'?
Trapezium is lateral (thumb side), articulates with the first metacarpal. Trapezoid is medial to it. Memorize 'Trapezium goes with Thumb' — both start with T.
Which carpal is the pea-shaped sesamoid?
Pisiform — from Latin 'pisum' (pea). Sits on top of the triquetrum. Palpable at the ulnar side of the wrist.
Are there cleaner alternatives to the classic mnemonic?
'Straight Line To Pinky, Then To Come Home' works if you don't like the classic. Whichever sticks is the right one.
Do I need to memorize joint articulations?
For preclinical anatomy, yes. Focus on scaphoid-radius, lunate-radius, pisiform-triquetrum, trapezium-first-metacarpal, hamate-hook (Guyon's canal).
Any Step 1 relevance?
Yes — scaphoid fracture, hook of hamate fracture (median vs ulnar nerve), triangular fibrocartilage complex injury, and carpal tunnel content all show up.
