title: Fascial feeder and perforator-based V-Y advancement flaps in the reconstruction of lower limb defects.
abstract: The principle of the V-Y advancement flap has been used since its first description by Blasius (1848) for reconstruction of smaller defects. We wish to describe V-Y advancement flaps, the design of which includes distinct perforator or fascial feeder vessels, which may originate from periosteum, muscle, cutaneous nerve or from large tendon sheaths. These flaps are planned in an oblique manner when there is a defect over the anterior, antero-lateral or antero-medial aspect, and in a vertical manner when there is a defect over the posterior aspect of the leg. The main advantage of this design is the ability to close the secondary defect primarily, allowing adequate cover of the defect, particularly in the pre-tibial region, without the unsightly divot left by a split skin graft in this area. When the flap includes branches of the long saphenous nerve on the medial aspect, superficial peroneal nerve laterally or sural nerve posteriorly it results in a sensate flap, giving protection in this vulnerable area, which has previously not been possible. We describe 40 cases where perforator-based V-Y advancement flaps have been used to cover large defects of the lower leg following excision of malignant skin lesions and in selected trauma cases that do not involve degloving injuries. This technique allows adequate soft tissue cover in the pre-tibial area and around the ankle with excellent aesthetic results. The planning, operative technique and the results with case presentations have been described.
