This is a BIG de-markation debate between plastics and orthopods.
Feet are undoubtedly orthopaedic.
Hands are in the realm of plastics (and reconstructive surgeon) although some orthopaedic surgeons specialise in hands as well. In our Emergency Department (level 6 ED, tertiary referral hospital) hands are only referred to the plastic surgeons.
Which ever specialty you go to make sure they are a hand specialist not a generalist plastics/orthopaedic surgeon.
