Deep cut, joint of my finger, it was glued 10 days ago, bandage off, wound had been reopened, now scarring across the gap, too late for stitches? scar

Old cut: Go to hand surgeon wound can be closed late and can heal safely without stitches but you need an expert eval to choose best way.

Probably too late: It is probably too late for stitches at this time and probably better to allow it to heal and perform light massage to promote maturation of the scar tissue. I assume from the initial repair that no deep tissues were injured.
