My finger is crooked from a fracture a few years ago. is there any way to fix it that doesn't involve a bone cut?

X-ray needed: it would be difficult the question without an x-ray. However via the description it most likely would involve surgical intervention.

Fingers than Toes.: Fingers are a lot like toes. Almost any angular deformity can be corrected with just one or more cuts of a saw. The real issue is whether or not, or exactly how much, mobility will be sacrificed to correct the deformity. Not always, but most of the time, loss of range of motion is a consequence of such corrective surgeries. This result is a little more acceptable in the toes than in the fingers.
