Background Soleus muscle flap can be used in different modifications to reconstruct lower limb defects. It can be proximally based, distally based, island or reversed flow flap. The first description of the soleus muscle as an island flap supplied by one distal perforator was reported by Yajima et al ( Plast Reconstr Surg . 1995;96:1162–1168). However, its use as a propeller flap supplied by the distal perforators and rotated for more than 90 degrees was not described yet. Obejectives The aims of the study are to study the detailed vascular anatomy of the distal perforators of the soleus muscle flap and to demonstrate the applicability of using it as a propeller flap. Patients and Methods A total number of 42 patients were included in this study. These patients had various distal leg and foot defects. All patients were assessed preoperatively by Doppler study and computed tomography angiography to define the vascular status of the leg. The muscle was raised as a reversed flow flap, based on 1 or more distal perforators and its feeding vessel (posterior tibial artery) after being dissected and divided proximally. The muscle was rotated for more than 90 degrees to reach distal leg defects and approximately 180 degrees to reach the foot defects. Results All flaps survived completely with good and durable coverage. The vascularity of the limb was not affected in all patients. There was no functional donor site morbidity. Conclusions The reversed flow hemisoleus muscle flap supplied by the distal perforators and the posterior tibial artery has a great arc of rotation that can cover all distal leg, ankle, and foot defects. Therefore, it can be used as alternative to free flap in lower extremity reconstruction. A new nomenclature is suggested for this flap which is the propeller hemisoleus muscle flap.
