Wiederherstellung der verbrannten Extremität durch Transplantation freier Lappenplastiken

Free tissue transplantation in burn reconstruction presents a major challenge to reconstructive surgeons. The results of a retrospective analysis of 68 free flaps in 55 patients are reported. This experience facilitated the establishment of reconstructive principles and a decision-making algorithm for primary and secondary reconstruction of burned extremities. Fourty-two free flaps were used for primary reconstruction. The indications were predominantly extremity salvage.The safety of the microsurgical procedures is correlated with the timing of the reconstruction. The failure rate of the free flaps was 24% in primary reconstruction. Due to an increased post-traumatic thrombogenicity, the period between 5 and 21 days had the highest risk of flap failure (40%).Twenty-six flaps were used for secondary reconstruction, with a success rate of 100%. Due to their elasticity, adipo- and fasciocutaneous flaps provide a useful option for the release of contractures. The large variability demonstrated by the use of 19 different types of free flaps showed that the reconstruction of burned extremities requires a reconstructive concept individualized to each patient as well as sophisticated microsurgical techniques. This clearly demonstrates the importance of a close link between primary burn treatment and reconstructive plastic surgery.
