Principles of definitive soft tissue coverage with flaps.

Despite the emergence of negative pressure wound therapy with reticulated open cell foam (NPWT/ROCF) as delivered by V.A.C.(R) Therapy (KCI, San Antonio, TX) for orthopaedic trauma, vascularized tissue transfer whether it be pedicle, free, or tissue transfer using the operating microscope or as an island, remains the mainstay of soft tissue reconstruction for orthopaedic traumatology. The critisism of microvascular procedures has been that they are lengthy, costly, and required technical expertise to perform. While technical skills are required, microsurgical care has evolved into a routine operation with high degrees of success in experienced hand. The problem that still remains is access to surgeons who are interested in soft tissue reconstruction and can perform definitive coverage with flaps. There is a need in the orthopaedic community to solve the problem of lack of flap surgeons and as a result, NPWT/ROCF has been touted as the answer to flap reconstruction. NPWT/ROCF is an important addition to soft tissue reconstruction but it serves as a bridge rather than definitive coverage in many hands. Just as wound technology is evolving with tissue substitutes, growth factors and NPWT/ROCF flaps technology continues to advance with new perforator flaps and local regional flaps, particularly the sural flap, coming on line as mainstays of soft tissue reconstruction.
