Missile Injury by A Weed Wacker Resulting in a False Aneurysm of the Brachial Artery

A novel now commonly used device in many countries called a "weed-wacker" is a mechanical rotating device with a cord used to trim lawns and grass. A case of a 14-year old boy with a false aneurysm of the brachial artery is presented; he sustained a missile injury by a piece of rusty steel projected by use of a weed wacker. Missile injuries by nail guns and bullets have been documented in the literature; however, this mechanism of injury by a weed-wacker has never been previously described and is presented as a unique mechanism of injury and brings attention the issue of safety with the use of the weed-wacker.
