Symptomatic glenoid labrum tears tend to occur in overhead athletes and middle aged laborers. Injuries can be provoked by a single, acute traumatic event, such as a traction injury while falling or in a more chronic manner, secondary to repetitive overhead motion. The most common complaint is shoulder pain, particularly with overhead activities. There may be feelings of instability, secondary to interposition of the labrum between the glenoid and humeral head, preventing congruent fit. Athletes may feel painful ‘catching’ or ‘popping’, particularly during the cocking phase of throwing or describe a loss of throwing velocity or ‘dead arm’ syndrome .
