Radial Sensory Nerve Entrapment

Fifty-one patients with entrapment of the radial sensory nerve were examined. The entrapment was usually due to a crush or twisting injury to the wrist or forearm or to repetitive pronation supination movements at work. Presenting symptoms were usually pain or burning over the dorsoradial aspect of the wrist, aggravated by pinching or gripping activities. Results of physical examination demonstrated a positive Tinel's sign over the radial sensory nerve as it exits the deep fascia, a false-positive Finkelstein test, and a positive hyperpronation provocative test. The results of nonoperative and surgical management are presented.
