An "Expanded Zone" Concept for Soft Tissue Coverage of the Upper Extremity: Upper Extremity "Expanded Zones".

Vascularized soft tissue coverage of open wounds of the lower extremity has long been predicated on the zone of injury and the available local flap donor site options found therein. A hypothesis was presented decades ago in this journal that attempted to extend a similar approach to simplify upper extremity coverage as well, but appears to have long been forgotten. However, with the emergence of the fasciocutaneous flap and its offspring the perforator flap, now a plethora of additional local flap options within the upper extremity may justify this idea being further considered.

On a Hunt for the "True" Septocutaneous Perforator: A Histology Cross-Section Study.

Background:  Modern trends in reconstructive surgery involve the use of free perforator flaps to reduce the donor site morbidity. The course of perforator vessels has a great anatomic variability and demands detailed knowledge of the anatomical relationships and the variability of the course of the perforators. The numerous modifications to perforator nomenclature proposed by various authors resulted in confusion rather than simplification.
