Abstract
Fingernail and toenail injuries are common and require a refined approach for optimal cosmetic outcome. This chapter discusses management of nail and nail bed injuries, utilizing the newest data regarding epinephrine use in fingers and toes, using tissue adhesives for nail bed repairs, and the utility of prophylactic antibiotics for open distal phalanx fractures.

Presentation  
    Blunt trauma to the distal phalanx may result in nail avulsion, nail bed laceration, and distal phalanx fractures. The nail may be completely avulsed, partially held in place by the nail folds, or adhering only to the proximal nail bed (Fig. 135.1). On occasion, an exposed nail bed will have a pearly appearance, with minimal bleeding, making it seem as if the nail is still in place when it actually has been completely avulsed. See the anatomy of the fingernail in Fig. 135.2.
