The investigator took ROM measurements for the metacarpophalangeal joints, the interphalangeal joints, and the wrist (palmar flexion, hyperextension, radial flexion, ulnar flexion).
The investigator recorded ROM measurements for the metacarpo-phalangeal joints; the interphalangeal joints; and the wrist palmar flexion, hyperextension, radial flexion, and ulnar flexion.
Nerves were located according to specific twitches elicited by their stimulation (musculocutaneous nerve; forearm flexion: median; radial flexion
of the wrist, second and third finger flexion, pronation: ulnar; ulnar flexion of the wrist, fourth and fifth finger flexion, thumb adduction: radial; wrist and/or finger extension with or without forearm extension).
Early editions of Merrill's Atlas of Radiographic Positions and Radiologic Procedures[1,2] use radial flexion
and ulna flexion to describe movement toward the radial or ulna side of the wrist, with no mention of the word "deviation." Newer editions of Merrill's, however, note that ulna flexion or movement toward the ulna is "sometimes nebulously called radial deviation."
