The selection of recipient vessels is crucial when reconstructing traumatized lower extremities using a free flap. When the dorsalis pedis artery and/or posterior tibial artery cannot be palpated, we utilize computed tomography angiography to verify the site of vascular injury prior to performing free flap transfer. For vascular anastomosis, we fundamentally perform end-to-side anastomosis or flow-through anastomosis to preserve the main arterial flow. In addition, in open fracture of the lower extremity, we utilize the anterolateral thigh flap for moderate soft tissue defects and the latissimus dorsi musculocutaneous flap for extensive soft tissue defects. The free flaps used in these two techniques are long and include a large-caliber pedicle, and reconstruction can be performed with either the anterior or posterior tibial artery. The preparation of recipient vessels is easier during the acute phase early after injury, when there is no influence of scarring. A free flap allows flow-through anastomosis and is thus optimal for open fracture of the lower extremity that requires simultaneous reconstruction of main vessel injury and soft tissue defect from the middle to distal thirds of the lower extremity.

Flap Closure

Covering defects by free-tissue transfers enable surgeons to reconstruct or salvage the lower extremity injured or amputated in high-energy traumas which result in extensive damage to soft tissue, bone, tendons, vessels and nerve. The timing of the reconstruction using flaptechniques is extremely important. It can be divided into three categories: "primary free flap closure" (12 to 24 hours), "delayed primary free flap closure" (2 to 7 days), and "secondary free flap closure" (after 7 days). Our treatment of choice in an isolated complex injury of a lower extremity with a soft tissue defect is "primary free flap closure" providing improved funcional and aesthetic results, and psychologically benefit through lowered morbidity of the patient.

Sole Of The Foot

Free flap transfer for soft tissue defects involving the sole of the foot have been important in limb salvage. The functional capacity of 16 patients is documented. From our data, free flaps to weightbearing surfaces of the foot give satisfactory results in patients less than 40 years old and salvage is rewarding. Older patients had less than satisfactory results. When the only alternative is an amputation, free flap salvage may still be indicated.

Objectives. Lower extremity ulcers are quite common in patients with autoimmune diseases. Due to chronic use of immunosuppressants, these wounds may develop into deeper wounds resulting in exposure of bone or tendon, which in turn may require free tissue transfers for coverage. The author reviewed perforator free flap transfers performed in this group of patients and analyzed the results. Methods. A retrospective review was performed on all patients who underwent perforator free flap transfer for coverage of lower extremity ulcers without trauma, over a 10-year period. Patient demographics, administered immunosuppressants, and flap and donor site complications were analyzed. Results. Twenty-two perforator free flap transfers were performed in patients with autoimmune diseases, including 18 thoracodorsal perforator flaps, 2 anterolateral thigh flaps, and 2 deep inferior epigastric artery flaps. There was no total flap loss, but there was a high rate of partial flap necrosis (40.9%) and wound dehiscence (40.9%). Intake of corticosteroids was significantly associated with postoperative complications ( P < .05). Conclusion. As partial loss of flap and wound dehiscence is much more common in this group of patients, treatment may take longer, and a fully informed consent should be obtained preoperatively. Surgeons should not avoid performing perforator free flap transfers in patients with autoimmune diseases under immunosuppression; instead, much more preparation and caution are required.

Soft tissue loss in the lower leg presents a challenge for reconstructive surgeons. When a defect is large, free flap transfer provides a well-established method, but local flaps are more convenient for small to moderately sized soft tissue defects. When a defect is very small, even local flaps are too invasive, leave additional scar, and cause bulky flaps. We present our case aiming to underline the usefulness of percutaneous aponeurotomy and lipofilling in a small lower leg defect with several advantages.
