Free Vastus Lateralis Muscle Flap in Lower Extremity Reconstruction: Clinical Experiences

Abstract

Free-tissue transfers have become an accepted new method of treatments in reconstruction of the lower extremity since 1972. This treatment option has profoundly influenced the fate of many salvaged limbs that in retrospect would have been amputated. From Dec 2001 to Jul 2003, seven patients with defects over the lower extremity underwent reconstructions using a free vastus lateralis muscle flap. There were six males and one female with an average age of 58.1 years (range 48 to 66 years). All flaps except one were successful without major complications. The average follow-up was 9 months (range 6 to 12 months). The six patients with established wound complications experienced complete resolution of their ability. Limb salvage was achieved in these six patients and their ambulation was restored. In comparison with other muscle flaps, we found the vastus lateralis muscle flap is an excellent option for lower extremity reconstruction due to its advantages of ease in harvesting, allowing two-team approach, relatively long vascular pedicle as well as availability of adequate muscle volume and lower donor-site morbidity. Also, preoperative angiographic or Doppler confirmation is valuable to decrease flap complication.
