RESUMO
Mild traumatic brain injuries, if repeated, can cause permanent brain damage, or even death. I examined five published documents(three judicial decisions, one official injury report, and one book)to analyze incidents in which high school students who, while practicing judo, experienced acute subdural hematoma(ASDH)with grave outcomes, despite the fact that they had been examined by neurosurgeons. The five students, first-grade boy and girl of junior high school and two first-grade boys and one second-grade girl of senior high school, were hit on the head during extracurricular judo practice and were taken to the neurosurgery department of different hospitals. They were all novices or unskilled players. The initial diagnoses were ASDH in three cases, concussion in one, and headache in one. Although the surgeons, except in one case, prohibited the students from returning to play, the juveniles resumed judo practice soon. Some of them complained of continued headaches, but they kept practicing. Between 17 and 82 days after the first injury, they received the fateful hits to their heads, and they were brought to the emergency rooms. MRI and CT revealed ASDH in all;two of them died, and the other three remain in persistent vegetative state. Neurosurgeons should take the initiative to prevent severe brain injury of young athletes through collaborations with the athletes themselves, fellow athletes, family members, coaches, teachers, athletic directors, and other physicians. They should pay close attention to headaches and other signs and symptoms of concussion and prohibit the athletes from returning to play until they are confirmed to be symptom free for recommended periods, insisting that safety comes first.
