Which treatment works the best and fastest for finger laceration?

Stiching: There is only one treatment is to approximate the wound edges. Depending on the depth of the laceration and its width, you may need to have it sewn (sutures placed) or may just have it glued or steri strips (pieces of glu like paper) placed or if really superficial may just need to have a bandade place over it.

Depends: Some need sutures. Butterfly bandages. Or even surgery. Depends on the location on the finger and the depth of the laceration.

Suturing is faster: Depends on what needs to be repaired, but assuming the skin is separated; cleaning and suturing the wound closed will allow it to heal faster than leaving it open. There are possible risks so it should be evaluated by a medical professional.

Tendons,Nerves,Blood: In addition to the skin on the finger which needs to be closed, there are other vital structures in the fingers that may need prompt attention by a doctor. This includes the tendons that straighten and bend the fingers; nerves that give sensation; arteries that carry blood; and bones. If there is any difficulty moving the finger, numbnes in the tip or the tip is pale go to the er.

General wound care: The fasted and quickest method to assure optimal healing is accurate and close tension free approximation of the wound edges to expedite wound epithelialization and minimize inflammation in a clean but moist environment.
