Radial nerve entrapment or compression in the upper extremity is relatively rare compared to medial nerve or ulnar nerve entrapment and compression. Various syndrome types are defined according to the location of radial nerve entrapment and the pattern of symptom expression. In the upper arm, Saturday night palsy or honeymoon palsy occurs. Around the elbow, posterior interosseous nerve entrapment syndrome, which involves pure motor symptoms, and radial tunnel syndrome, which mainly involves pain symptoms, can develop. Finally, superficial radial nerve entrapment occurs in the distal forearm and has the symptom of painful or abnormal sensory disturbances of the hand. Conservative treatment is usually the first choice for radial nerve neuropathy, unless there is motor paralysis. Surgical treatment can be considered if there is no improvement after adequate conservative treatment.
