Detailed Description:

To evaluate bleeding, all patients with onychocryptosis will be operated on with the same technique. In the experimental groups, once the surgical procedure has been completed on both edges of the nail, hemostatic collagen will be applied in the experimental groups (experimental group 1- medium porosity collagen and experimental group 2-high porosity collagen) In all groups, including the control, once the intervention was finished, the same bandage was performed with the same number of gauze pads. At 72 hours, the gauze set will be removed to weigh it using a precision balance and quantitatively evaluate the amount of bleeding. In this way, a comparative study can be carried out between the 3 groups and determine if there are statistically significant differences or not, and can determine if lyophilized hemostatic collagen is useful in nail surgery and if there are significant differences between both experimental groups, determining if the percentage of porosity in a hemostatic is relevant in the hemostatic effect.}}
