[Specific features of wounds with a self-defense traumatic weapon "Osa"].

Specific features and outcomes of wounds with a traumatic weapon of self-defense "Osa" were analyzed in 24 patients. Mean age of the wounded was from 21 to76 years. In 20 patients there was a single wound, in 4 patients it was multiple, in 7--blunt, in 12--perforating and 5 patients had gutter wounds. All the patients were treated according to the principles of field military surgery. Five patients had severe wounds: penetrating fracture of the skull (2 of them died), fracture of the shoulder (1 case), injury of the main artery (1 case), of the pleura (1 case). The wounds were closed up by primary intention in 19 patients, by second intention in 4 patients. The authors' experience shows that a traumatic weapon of self-defense "Osa" rather often caused permanent harm to health and can be mortal. Active surgical strategy in treatment of such patients prevents the development of serious infectious complications.
