[The "light" version of a perforator flap: significance of the Keystone Designed Perforator Flap Concept (KDPFC) in the lower extremity].
Since the KDPFC was first described by Behan et al. in 2003, there have been a number of publications about this technique with case series between 1 and 300 flaps, and some have described further modifications of the design of the flap. The flap design resembles the keystone of a Roman arch and is based on the angiosome concept. The flap is a perforator flap, but does not require microsurgical dissection or preparation of the perforators. The technique is efficient and relatively simple to perform. With a few exceptions, it can be performed anywhere on the body. Although there are a large number of publications, not much data has been published on the complications, limitations and disadvantages of the technique. ⋯ The KDPFC is a valuable addition to the reconstructive armamentarium. Although delayed wound healing has been observed in some cases, this flap concept can replace other local or regional flaps, also in more complex situations. Care must be taken in patient selection and, in particular, in large defects and difficult topographical areas on the distal lower leg. In these situations, other reconstructive options may be more appropriate.
