—Report of Four Cases—

Abstract

Four cases of acute subdural hematoma in judo players are presented. Three were teenagers and one a young adult. Three sustained very severe injuries involving rupture of the bridging vein draining into the superior sagittal sinus without primary cortical laceration. These four cases are described and the incidence and nature of judo-related head injuries are discussed.
