In this study, the vascularization of the septo-fasciomyocutaneous vessels originating from the fibular artery was defined as basis for a chimeric flap for free microvascular tissue transfer in reconstructive surgery. For this purpose ten fresh cadaver legs were dissected and the vessels running into the posterior intermuscular septum (PIS) were identified after injection of methylene blue. The number of vessels were noted and evaluated at the lateral border of the proximal, middle and distal thirds of the fibula length. In addition, methylene blue injection was performed to confirm the connection between the fibular artery and the overlaying fascia through these septal vessels and adjacent muscles as the lateral hemisoleus (HS) and the flexor hallucis longus (FHL) muscle.
All specimens had periosteo-septal vessels running in the lateral aspect of the fibula originating into the resected fibular bone, the fasciocutaneous flap and dorsally located muscles. The mean number of vessels was 7.6 with a mean diameter of 1.2 ± 0.6 mm (range: 0.3–3.0 mm). 88.9% of the vessels occurred in the proximal and middle thirds of the legs. The described anatomy allows to raise a flap which could be dissected as a triple fascio-osteomyocutaneous flap for microvascular tissue transfer.
