The etiology of the isolated superficial radial nerve neuropathy is often associated with repeated use of wrist watches, falling, forearm fractures, surgical operations such as fracture fixation and arthroscopic procedures, steroid injections, acupuncture, use of handcuffs, repetitive supination, pronation, ulnar flexion
activities, compression of extensor carpi radialis and/or brachioradialis tendons, presence of neuroma, lipoma or ganglion cyst in the wrist as well as exposure to excess cold.
The investigator took ROM measurements for the metacarpophalangeal joints, the interphalangeal joints, and the wrist (palmar flexion, hyperextension, radial flexion, ulnar flexion
Although much of the literature refers to the treatment of radial head dislocation (anterior or posterior) by means of an ulnar osteotomy (ulnar flexion
or extension osteotomies for the treatment of anterior and posterior dislocation of the radial head), described by Bouyala and colleagues (14-16) and Hiramaya and coworkers, (17) the main indication of this procedure is the presence of residual deformity of the ulna or radius with a concave radial head articular surface.
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).
