Anatomy Bones Carpal Bones Scaphoid Lunate Triquetral Pisiform Trapezium Trapezoid Capitate Hamate Easy way of remembering carpal bones..starting from the lateral most bone of the proximal row.. "SHE LOOKS TOO PRETTY,TRY TO CATCH HER" She-Scaphoid,Looks-lunate,Too-triquetral,Pretty-pisiform;;Try- trapezium,To-trapezoid,Catch-capitate,Her-hamate

Carpal Bones S. Scaphoid L. Lunate T. Triquetrum P. Pisiform Tm. Trapezium Td. Trapezoid C. Capitate H. Hamate (*=hook)
4
"SHE LOOKS TOO PRETTY,TRY TO CATCH HER" She – Scaphoid Looks – Lunate Too- Triquetral Pretty – Pisiform Try – Trapezium To – Trapezoid Catch – Capitate Her - Hamate
5
Scaphoid (She) Largest bone in the proximal carpal row Most commonly fractured bone in the wrist
6
Lunate (Looks) Gets it’s name from its semilunar shape
7
Triquetral (too) Sits below the Pisiform
8
Pisiform (Pretty) Sits on top of the Triquetral/ Triquetrum
9
Trapezium (Try) Sits below the 1 st metacarpal
10
Trapezoid (To) Sits directly below 2 nd metacarpal
11
Capitate (catch) Sits directly below the 3 rd metacarpal
12
Hamate (her) Sits below the 4 th and 5 th metacarpal
13
Metacarpals I - Thumb II - Index III - Middle IV - Ring V - Pinkie
14
Phalanges Digit 1 (thumb) has a proximal and distal phalange Digits 2 – 5 each have a proximal, middle and distal phalange
15
Hand Joints CMC- Carpometacarpal Joints Connects Carpal Bones to metacarpals MP - Metacapophalangeal Joints Connects Metacarpals and Proximal Phalanges PIP- Proximal Interphalangeal Joints (2 -5) Connects Proximal Phalanges and Middle Phalanges DIP- Distal Interphalangeal Joints (1 – 5) Connects Middle Phalanges and Distal Phalanges
16
Carpal Order Wrist to Finger tips Carpal bones Carpometacarpal Joints Metacarpals (1 – 5) Metacapophalangeal Joints (1 -5) Proximal Phalanges (1 – 5) PIP- Proximal Interphalangeal Joints (2 -5) Middle Phalanges (2 – 5) DIP- Distal Interphalangeal Joints (1 – 5) Distal Phalanges (1 – 5)
