What do people call a hand specialist?

That's the name: Hand care/hand surgery developed as a sub-specialty during the second world war; we have no latin name. Hand surgeons come from orthopaedics, plastic and general surgery; we have additional training in the upper limb beyond our post-graduate residency. We treat problems of nerve, vessel, bone, joint, skin; we treat the upper limb and hand as a functional unit... And work with hand therapists.

"doctor": Most plastic and orthopedic surgeons can do hand surgery. Ps usu better for soft tissue; ortho for joints. Wrist, esp arthroscopy usu done by drs that limit their practice to hand.
