radial column takes about 75% of load, while the ulnar column takes about 25% of load. Radial and Ulnar Deviation Radial deviation: the scaphoid flexes

The examiner applies passive ulnar deviation to the patient's wrist while their other hand holds their forearm on the ulnar side. A positive test is where
