"Stingers" in adolescent athletes.

Brachial plexus injuries commonly occur in athletes participating in contact sports. The incidence of transitory brachial plexus injury is approximately 30% to 50% over the course of a high school, college, or professional football player's career. These injuries are called "stingers" or "burners" because of the associated tingling that occurs in the upper extremity after the injury. Brachial plexus injuries are poorly understood and sometimes are difficult to manage. Appropriate knowledge and understanding of these injuries along with prompt recognition, diagnosis, and treatment are essential for optimal care of the injured athlete and for the athlete's timely return to play. Most injuries occur by one of three mechanisms: traction, compression, or hyperextension and compression. Injuries are clinically classified as neurapraxia, neurapraxia/axonotmesis, and neurotmesis according to their symptomatology and the pattern of symptom resolution. Most injuries are either a neurapraxia or a neurapraxia/axonotmesis. Most athletes recover completely and can return to play after they are asymptomatic and have regained full sensation, strength, and range of motion. Protective equipment has been introduced to decrease the occurrence of stingers. Education of the athlete, the family, and coaches is important to help them to understand and to assist in managing these injuries.
