Brief Summary

In the field of reconstructive microsurgery, donor site morbidity after free flap harvest is one of the key factors to consider when choosing among different options of free flap. Peroneal artery-based free flap, such as fibula flap or peroneal flap, is one of the popular options of free flap. There are a plenty of literature using a variety of modalities to evaluate the donor site morbidity after free fibula harvest, such as gait analysis. Elastography has been used to evaluate the stiffness change of soft tissue, such as skeletal muscle, or liver. The purpose of this study is to use elastography to evaluate the stiffness of lower leg muscle after peroneal artery-based free flap harvest.
