A unha em pinça pode apresentar três tipos clínicos, mais comuns, sendo a unha em telha um deles. As causas podem ser hereditárias ou adquiridas. Os dedos dos pés são acometidos com maior freqüência.

“…Although these procedures can have high cure rates, they are considered invasive with prolonged healing time, associated pain, and the possibility of postoperative infections and are not recommended for elderly patients or for those with associated comorbidities. 1,6,8,[13][14][15] Phenol application time remains a challenge. An effective tourniquet and the removal of blood from the surgical wound are important factors, reducing the contact time of phenol on the nail matrix.…”

[7][8][9][10][11][12] Zook's procedure proposes flattening the nail bed and lateral portions of the matrix using dermal grafts that are placed through the incision from the tip of the finger to the matrix.
