What are the 2 most anterior carpal bones?
Where is the anatomical snuff box located?
half-moon shaped carpal bone
articulates to the the pisiform
sits on the anterior side of triquetrum and looks like a pea stuck to it
articulates with the base of 1st metacarpal
its rounded head fits into the cresent shape of the lunate
the "hook", it projects anteriorly
The 1st metacarpal contains _________ on its _________ side below the neck.
small sesamoid bones
A________ is often seen on the 2nd metacarpal.
What is formed by the concave surface of the carpal bones?
What projection is used to best demonstrate the carpal canal?
Tangential-CR barely skims the part to decrease superimposition
What is best visualized in the tangential projection?
hamulus of hamate
