The use of vascularized, composite and prepared free transplants is a recent technique. Two types of transplants were grafted in rats (150 operated cases). For the prefabricated free transplants, each component remains vascularized by rami of the main pedicle: vessels, nerves, bone, periosteum, cartilage, muscle, skin (50 cases). The graft is transplanted immediately. Neovascularized free transplants are quite different, the various components being laid around the vascular pedicle (100 cases). Neovascularization revascularizes the components. The free graft is transplanted 5 weeks after being prepared. The period of observation ranges from 3 to 12 months. Observation includes macroscopy, arteriography, histology and intravascular dye injections. The results with prefabricated free transplants show normal vascularization of soft tissues. There is bone in all cases, it is normal in 80% of cases. In neovascularized transplants, the bone is normal in 33% of cases only, and totally resorbed in 46%. Prefabricated free transplants produce better results than neovascularized free transplants and must be preferred. The merit of these composite free transplants is that they produce free transplants selectively, using various tissues and chosen vascular pedicles. These transplants are a useful and futuristic alternative for highly sophisticated reconstructive surgery.
