Nail-gun limb injuries.

We present four cases and a review of the literature regarding nail-gun related limb injury. Nail guns have significant potential to cause limb and other major injuries. In most cases improper use of the nail-gun is the single most important factor in causing such types of injuries. Treatment of these injuries requires careful assessment of the limb and the type of nail involved in order to enable safe extraction. We recommend the introduction of training in the workforce to encourage awareness of the danger of such devices. We also emphasize the continuing requirements for improved workplace safety and adequate safety equipment when working with such dangerous devices.
