The hand is a commonly injured area of the body, with 16% to 22% of all hand injuries occurring at work. We present two cases of nail-gun injuries to the hand and outcomes of nail removal. 5, 13, 14, 19 Consequently, a systematic approach toward understanding the mechanisms of nail-gun injury, as well as recognizing complicating factors in the surgical management of these injuries, is essential for appropriately treating these patients. Direct bony injuries to the digits, hand, and wrists as well as penetrating injuries to the interphalangeal and radiocarpal joints have been described. 7, 11 The majority of injuries involve retained nails with trauma limited to the surrounding soft tissues. 2, 12 – 20 Most of these workplace injuries occur during routine use and are due to accidental discharge, careless handling of equipment, overpenetration of structures by the projectile, ricochet or shattering of the projectile, and the structural unsoundness of the receiving material. 5, 12 – 14 The radial aspect of the nondominant hand, as it is typically used to grip or steady the structures being nailed, can easily cross the nail's line of fire, and thereby is the body part most often injured. Since the introduction of pneumatic-powered nail guns to the construction industry in 1959, there has been an increasing number of industrial accidents involving these devices, with the most frequent area of injury being the hand. In both devices energy is utilized to fire bolts, metal studs, nails, pins, and fasteners into wood, metal, concrete, and masonry by pressing a contact trip or sequential triggering mechanism on the gun. ![]() 5, 8 – 10 The more commonly used lower velocity nail guns, in comparison, eject nails indirectly by activating a captive piston usually by means of compressed air. 2, 3, 6, 7 High-velocity devices eject nails by detonating explosive cartridges directly behind the gun barrel. 3 – 5 This can be equated to the firing capacity of a. 2 Powered by either an explosive charge or compressed air, this tool generates enough force to fire a projectile up to 10 cm in length, with velocities as high as 1400 feet per second, into fully stressed concrete. The nail gun is a mechanical device used to frame wooden structures, secure wood to concrete supports, and in multiple other construction and home improvement applications. 1 In addition, nail guns are frequently utilized by the nonprofessional consumer population for general construction. Pneumatic nail guns are efficient, readily available, and easy to use, making them a common tool employed in residential construction and wood-production industries. Nail-gun injuries to the hand necessitate appropriate evaluation techniques, understanding of surgical management versus nonsurgical management, and awareness of potential pitfalls in treatment. Conclusion: Healthcare providers must understand and educate patients on the prevention mechanics of nail-gun injuries. Treatment is based on the severity of injury and the presence and location of barbs on the penetrating nail. Nail-gun injuries to the hand vary in severity on the basis of the extent of structural damage. Operative removal of the nail and wound care resulted in successful treatment in both cases. Results: Two patients present with soft tissue injuries to the hand with the nail embedded and intact at the injury site. A review of the literature and discussion of clinical evaluation and treatment of nail-gun injuries to the hand are presented. Materials and Methods: We report on two patients with nail-gun injuries to the hand. The most common site of nail-gun injuries in both industrial and nonoccupational settings is the hand. ![]() When used properly with appropriate safety precautions, it can facilitate production and boost efficiency however, this powerful tool also has the potential to cause serious injury. ![]() Background: The nail gun is a commonly utilized tool in carpentry and construction.
