Overview

Overview

Finger nails are used for scratching, in defense, and, more obviously, to pick up small objects. However, the nail also protects the fingertip, contributes to tactile sensation, and plays an important role in the regulation of peripheral circulation. An abnormal nail is both a cosmetic and functional problem in that it catches on objects, particularly cloth, and causes finger pain and damage to the object.

Indications

Nail deformities that require nail removal can occur secondary to anything that causes injury or deformation of the nail bed. This may include infection, [1] self-mutilation, tumor, or trauma, as in the following [2] :

  • Onychocryptosis (ingrown nail) [3]
  • Onychogryposis (deformed, curved nail)
  • Onychomycosis (fungal infection of the nail) [4] (see the image below)

  • Chronic recurrent paronychia (inflammation of the nailfold) [5] (see the image below)

Anesthesia

Although many procedures like nail removal can be carried out safely under local ring block, some patients may opt for general anesthesia. The following anesthetic procedures are commonly used:

Equipment

Equipment includes the following:

  • Surgical preparatory supplies
  • Syringe, 5 mL
  • Needle, 27 gauge (ga)
  • Local anesthetic without epinephrine
  • Finger tourniquet (eg, rubber band, small Penrose drain, or the finger part of a glove)
  • Iris scissors or small Kutz periosteal elevator (nail elevator)
  • Straight hemostats (2)
  • Nonadherent gauze and tubular gauze dressing

Positioning

Position the patient supine.

Abduct the arm.

Place the hand on an arm extension with the palm facing down.

Technique

Scrub and drape the finger in a sterile fashion.

Administer local anesthetic to ring-block the finger.

Confirm that anesthesia is achieved (wait 5-10 min).

Use a straight hemostat to firmly secure a finger tourniquet around the base of the finger.

Insert the blades of curved Iris scissors or a small periosteal elevator beneath the free edge of the nail (hyponychium). Gently open and close the Iris scissors blades or gently press the nail bed with the small periosteal elevator. Advance proximally in between the nail plate and the nail bed until the instrument reaches the nail fold.

Take appropriate care to avoid any further damage to the nail bed or overlying nail fold during this process.

Once the nail is sufficiently separated from the nail bed, it is gently removed by applying firm and steady distal traction using a hemostat.

Pearls

Apply a tourniquet at the base of the finger to minimize bleeding.

Take appropriate care to avoid any further damage to the nail bed or overlying nail fold during nail removal.
