Q

Memonic for carpal bones

Which side do you start at and which side do you finish at?

A

Some Lovers Try Positions That They Can’t Handle

Scaphoid
Lunate
Triquetrum
Pisiform
Trapezium
Trapezoid
Capitate
Hamate

Start on the radial side, work your way across to pisiform, then back to radial for trapezium and finish on the ulna side with hamate
