Healing Magic and Physical Disabilities

[TheFlyingPhoton]

In my game, there is an NPC who has suffered a major injury to one of her arms, and at this point the hand is nonfunctional. My players may wish to resolve that, so is there any particular healing magic that would do so? A physical disability like this isn't a standard game condition, and the only thing I can find related is Regeneration healing amputation and several spells resolving mental conditions (which are often mechanical conditions).
Should I go with Regeneration, or something lower like a Heal or Restoration?

i would say only regenerate and/or wish/miracle will heal the person of that ''condition'', regenerate say that severed body members, broken bone and ruined organ grow back.

so a hand that is no longer functional is missing thing to make it work properly, so it will be grow back to make it functional again.

but that's just my interpretation of the situation and the spell regenerate

I agree, though if the injury isn't too severe a limited wish may be enough. Alternately, a divine caster could research a lesser regenerate spell that only mends bones and small tissues but doesn't regrow entire organs. All with GM fiat of course.
