largest carpal bone | capitate |
most frequently fractured carpal bone | scaphoid |
bones of the forearm | radius and ulna |
which forearm bone is the lateral | radius |
which forearm bone is medial | ulna |
which forearm bone is longer | ulna |
radial head articulates with | capitulum of humerus |
how many views of the forearm are there? | 2 PA and lateral |
radiographic views of the hand | PA, oblique, lateral |
when the hand is in the PA position, what position is the thumb in? | oblique |
