Microsurgery techniques are being applied to an expanding range of orthopaedic problems. Now the term super-microsurgery, coined by Koshima et al., is used to apply to the anastomosis of submillimeter vessels that is necessary in distal replants and perforator flaps. The discussion presented in this chapter includes microsurgical procedures appropriate for surgery of the hand, including the repair of small vessels and nerves; the transfer of composite tissue grafts using microvascular techniques in the upper and lower extremities; and our approach to the replantation of amputated parts.
