How to get the most out of your gastrocnemius and soleus flaps.

Abstract

Gastrocnemius and soleus flaps represent the workhorse local flaps to cover soft tissue defects of the proximal 1/3 and middle 1/3 of the leg, respectively. An important consideration before conducting a local flap is whether the flap can provide adequate coverage. The utility of the gastrocnemius flap can be increased using multiple techniques to increase the arc of rotation including the posterior midline approach, dissection at the pes anserinus and medial femoral condyle origin, scoring the fascia, and inclusion of a skin paddle. Concerning the soleus flap, the hemisoleus flap represents a technique to increase the arc of rotation. With a soleus flap, one must consider the soft tissue defect location, size, and perforator blood supply because these factors influence what soleus flap technique to use. This article discusses how to make the most out of gastrocnemius flaps and soleus flaps regarding maximizing coverage and ensuring successful flap outcome.
