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.
