Subunit Principle: Key Element for Plantar Reconstruction with Free Sensate Flaps

Purpose: Plantar wounds represent a frequent practice of the plastic and reconstructive surgeon. The uniqueness high complexity microarchitecture biomechanics plantar region explain complex challenge its reconstruction. With advances in microsurgery, including subunit principle, both applied restoration defects through use sensorineural free flaps have allowed an optimal reconstruction.Methods: A descriptive, retrospective study was carried out period time established between January 2016 2019, obtaining total 18 patients with defects, reconstructed using sensory flaps. Tissue stability, recovery protective sensitivity, early ambulation, correct footwear were evaluated.Results: most etiology secondary to oncological resections due melanoma (n = 12, 66.7%), followed by gunshot 4, 22.2%). Subunit 3 frequently involved 38.9% 7). In 88.8% cases, used anterolateral thigh flap 16) lateral antebrachial 22.2% 2). survival rate 100%. An average seven points obtained at 6 months based on Semmes-Weinstein test. mean for return their daily activities 2.5 months. 94.4% 17) recovered ambulation could footwear. Conclusion: reconstruction must systematic approached, taking principle as central point. treatment unprecedented option
