A 25-year-old man presented with hook nail and painful atrophic pulp over the tip of the terminal phalanx of the right thumb 3 months following a crush injury. Lateral nail folds were poorly defined and the nail was curved. The patient was unable to pick up objects with a precision pinch. Reconstruction was performed with Atasoy antenna procedure.
