Skin-softening techniques. Encourage the patient to apply warm compresses or to soak the toe in warm water for 10 to 20 minutes a day.
Barriers may be inserted between the nail and the periungual skin. Daily intermittent barriers may be used to lift the nail away from the lateral nail fold during regular hygiene activities. Tell the patient that a continuous barrier may be created using gauze or any variety of dental floss placed between the nail and the lateral nail fold, then secured in place with tape and changed daily.
Gutter splint. The gutter splint consists of a plastic tube that has been slit longitudinally from bottom to top with iris scissors or a scalpel. One end is then cut diagonally for smooth insertion between the nail edge and the periungual skin. When placed, the gutter splint lies longitudinally along the edge of the nail, providing a barrier to protect the toe during nail growth. The tube may be obtained by trimming a sterilized vinyl intravenous drip infusion, the catheter from an 18-gauge or larger needle (with the needle removed), or a filter straw. This tube can be affixed with adhesive tape, sutures, or cyanoacrylate.7
Patient-controlled taping. An adhesive tape such as 1-inch silk tape is placed on the symptomatic edge of the lateral nail fold and traction is applied. The tape is then wrapped around the toe and affixed such that the lateral nail fold is pulled away from the nail.8
