Outcomes and Risk Factors in Microsurgical Forefoot Reconstruction.

Background:  Defects at the forefoot frequently require microsurgical reconstruction; however, reconstructive failure can lead to results inferior to primary amputation. The purpose of this study was to identify independent factors affecting surgical outcomes and hospitalization time in these patients.

Methods:  All patients that underwent free flap reconstruction of the forefoot between 2008 and 2019 were reviewed retrospectively.

WALANT-Epinephrine injection may lead to short term, reversible episodes of critical oxygen saturation in the fingertips.

Introduction: Although the WALANT technique's long-term safeness has been demonstrated in many studies, there are only few data investigating its short-term effects on tissue perfusion and oxygen levels. It was hypothesized that, temporarily, critical levels of tissue perfusion may occur.

Methods: Seventeen patients, who were scheduled for different procedures in WALANT technique, were injected with 5-7 ml of 1% Articain containing 1:200,000 epinephrine at the finger base.
