We experienced a case of crush injury of the hand for which we performed a flap surgery and treated the necrotic parts placement using cultured allogeneic keratinocytes (Kaloderm^®) with good results.

The patient was a 31-year-old woman whose left middle finger was caught in a door, causing a crush injury. Although primary repair was performed, a 2 × 2.5-cm-sized necrosis developed, and a V-Y advancement flap was performed after the removal of dead tissues. However, a 1 × 2-cm-sized partial necrosis occurred and was treated using Kaloderm^®.

After the use of Kaloderm^®, the patient’s wound was healed, and no complications, except for mild pain, were observed for 1 year after the surgery.

If a necrotic site appears after flap placement of fingertip, its treatment is difficult. If used well, Kaloderm^® may be a good option for necrosis of the fingertips and other areas that are difficult to cure.
