Y1 - 2018 N1 - T2 - Reichman's Emergency Medicine Procedures, 3e AB - An ingrown toenail (onychocryptosis) is a common affliction that can occur in any toe. It most commonly afflicts the great toe, occurring when the lateral edge of the nail plate penetrates the soft tissue of the lateral nail fold. There are three stages of ingrown toenails.1 Stage I includes erythema, slight edema, and pain when pressure is applied to the lateral nail fold. Stage II includes the stage I findings plus signs of infection and a purulent drainage. Stage III is a magnification of the two previous stages with the addition of granulation tissue formation and lateral nail fold hypertrophy. Most ingrown toenails can be definitively managed in the Emergency Department by the Emergency Physician.
