Abstract

Gustilo Grade IIIB and IIIC open fractures of the lower extremity often involve complex wounds requiring bony fixation and soft tissue reconstruction. We present a case of a 32 year-old male who suffered a traumatic Gustilo Grade IIIB open fracture of the tibia and fibula with an extensive soft tissue defect. Reconstruction was first attempted with a turbocharged anterolateral thigh flap that failed due to venous thrombosis. Due to vascular injury, limited reconstructive options were available from the ipsilateral leg. Limb salvage was subsequently achieved with a chimeric cross-leg latissimus dorsi-serratus anterior (LD-SA) free flap based off the contralateral healthy leg, using the serratus for pedicle bridge coverage so that the latissimus could be fully used for defect coverage. Though not extensively described in the literature, this flap is a versatile reconstructive option for limb salvage in patients with Gustilo IIIB or IIIC injuries to the lower extremity.
