A new technique for hemipelvectomy.

A new technique for hemipelvectomy has been developed in which a large anterior well vascularized flap is used. The preservation of an anterior flap is essential if the posterior flap cannot be preserved because of tumor involvement. The vascularized anterior flap may be superior to the posterior flap because of less dermal necrosis. Use of the anterior flap may increase the ease of hemipelvectomy and reduce blood loss at operation.
