Abstract

Muscular hemorrhages around the scapula are frequently found in fatal drowning cases without injuries in the upper back at time of autopsy. The present study investigated the frequency of muscular hemorrhages around the scapula and determined the mechanism responsible for this phenomenon. Muscular hemorrhages around the scapula were found in 104 of 164 (63.4%) bodies assessed. Hemorrhage in the infraspinatus muscle was most common, followed by the supraspinatus muscle. These muscular hemorrhages were not associated with upper extremity injuries and were most frequently found in accidental drowning cases (78.7%), followed by cases of suicide (56.0%), and in natural disease prior to drowning (19.0%). We examined muscular hemorrhage around the scapula and cervical injuries that restricted the active motion of upper extremities in drowning cases. The vertebral level of cervical injuries were related to muscular hemorrhages around the scapula. These results suggested that muscular hemorrhages around the scapula were not a result of agonal convulsions but were caused by consciously active excessive motion of the upper extremities while drowning. Investigations of the muscular hemorrhages around the scapula can provide insights towards the manner of fatal drowning.
