[When the pig escaped, the cattle gun hit the knee].

Injuries sustained from a cattle gun are typically more severe than they appear. Fractures and infection are the primary concerns due to a coupling of a sustained penetrating impact, contamination of the bolt and residual foreign material left after penetration. This is a case report of an injury caused by a cattle gun. The initial assessment did not match the actual magnitude of the injury. Due to the severity of injuries of this kind they require a thorough assessment as well as specialized treatment in terms of debridement and high-yield antibiotics, as well as the possible fracture treatments.
