Navicular
- Tubercle is medial
- Hold by tubercle with nonarticular side up, tip of tubercle points to side
Medial (1st) cuneiform
- Kidney shaped articular surface distal
- Rough, nonarticular surface medial
- Kidney facet away from you and navicular facet toward you, only other facet towards side.
Intermediate (2nd) cuneiform

Lunate
-Flat side on table and most concave facet toward you, remaining facet rises up and toward side.
Triquetral
- Smallest facet is for pisiform & medial
- Square facet distal, long facet medial, facet for pisiform is superior and on side.
Pisiform
