Use of the TASER electronic control device by law enforcement and civilians is increasing. Advocates for the use of the device believe that it has reduced the number of officer and suspect injuries. However, the use of the device is not without complications. Many of these injuries to superficial body structures or those sustained in the postactivation fall have been described in the literature. Injury to deep structures of the abdomen and chest were previously thought to be unlikely given the length of the TASER barb. This case report of a 16-year-old male patient who suffered a pneumothorax after TASER activation is thought to be the first reported in the literature.
