The Application of Posttransfer Free Flap Expansion for Management of Severe Foot Crush Injury with Extensive Soft Tissue Loss: A Case Report.

Reconstruction of posttraumatic soft tissue defects has been revolutionized after the application of microvascular free flaps. However, standard flaps are limited in size and may not completely cover the defect. Flap expansion which is indicated in large defects with extensive soft tissue loss or shortage of donor tissue enables tension-free closure of large defects, minimal donor site morbidity, and better aesthetic outcomes.
