Scaphoid (She) Largest bone in the proximal carpal row Most commonly fractured bone in the wrist

Lunate (Looks) Gets it’s name from its semilunar shape

Triquetral (too) Sits below the Pisiform

Pisiform (Pretty) Sits on top of the Triquetral/ Triquetrum

Trapezium (Try) Sits below the 1 st metacarpal

Trapezoid (To) Sits directly below 2 nd metacarpal

Capitate (catch) Sits directly below the 3 rd metacarpal

Hamate (her) Sits below the 4 th and 5 th metacarpal

Metacarpals I - Thumb II - Index III - Middle IV - Ring V - Pinkie

Phalanges Digit 1 (thumb) has a proximal and distal phalange Digits 2 – 5 each have a proximal, middle and distal phalange
