ABSTRACT Reconstruction of defects around the ankle region has always been challenging for plastic surgeons. Distally based lateral and medial leg adipofascial flaps are among the flaps of choice for coverage of this difficult region. Presented here is the authors' clinical experience with these flaps, particularly emphasizing the complicated attempts in diabetic patients.
Seven skin defects around the ankle were reconstructed with lateral and medial leg adipofascial flaps. The lowermost perforators of the peroneal or posterior tibial artery were identified preoperatively, and a straight incision through skin only was made proximal to this perforator. With the skin flaps reflected, the adipofascial flap was than raised in the subfascial plane. The perforators to be retained in the base were located and the flap was then turned over to cover the defect, followed by application of a split-thickness skin graft over the flap. The donor site was closed primarily.
The ages of the patients ranged from 25 to 80 years, and the size of the flaps ranged from 3 x 5 cm to 7 x 10 cm. Four defects were reconstructed with lateral leg adipofascial flaps, and medial leg adipofascial flaps were used in three. Two flaps healed uneventfully. Partial or total graft loss and partial flap necrosis were observed in five patients, four of whom were diabetic.
Leg adipofascial flaps offer a valuable option for repair of defects around the ankle in many cases. However, adipofascial flaps should be used with caution in old, diabetic patients and, when performed, the probability of a second or third procedure should be considered.

    ABSTRACT: Lower extremity diabetic wounds have been a challenge to clinical surgeons because of the higher risk of limb ischemia, soft-tissue infection, and soft-tissue loss caused by the pathology of the disease. In the published data, the most commonly used reconstruction techniques include pedicled flaps, microsurgical muscle or musculocutaneous flaps, and microsurgical fasciocutaneous or perforator flaps. However, there is still no consensus about which type of flap should be preferred among various reconstructive options. It is therefore the aim of this study to review current articles describing distal lower extremity flap reconstruction in patients with diabetes to survey reported results from the literature.

    ABSTRACT: The distally based posterior tibial adipofascial flap is a useful option for distal leg and ankle coverage. Traditionally, its dimension is constrained by a length-to-width ratio of 2:1. We have increased this ratio to 4:1 by including the great saphenous vein and saphenous nerve with the flap. These structures with their venoneural network, and their connections with posterior tibial artery perforators, form the vascular axis of the flap. In our series of 21 flaps, 70% (n = 15) had ratios of 3:1 or higher. In remaining 30% (n = 6), the ratio was 2:1, as the defects were more proximal. Complications include one complete flap loss due to compression from tunneling and one superficial tip necrosis. Postoperatively, we performed wet-to-wet dressings, phlebotomy, and delayed skin grafting to optimize flap survival. Of 21 flaps, 20 were healthy after an average follow-up of 24 months.

    ABSTRACT: Soft tissue defects in the distal third of the lower leg are persistent and constitute a major problem in the reconstructive surgery. This study presents an analysis of the anatomical vascularization filed of ascending branch of the peroneal artery ramus perforans (PARS). The aim of this study was to assess reliability of the distal flap on the antero-lateral aspect of a lower leg distal third. Direct gentiana violet injection into the interosseal perforator of ten fresh cadaveric lower legs with subsequent corrosion acrylic preparation was performed to reveal vascularization filed of the ascending branch of the PARP. Height, length, diameter and communication of perforating branch and its subsequent smaller ascending and descending branches were determined. The CAMIA software was used. Our results show that the PARP is always present. Its origin from the peroneal artery is at the medial height of 66 mm when measured from the inferior border of the lateral malleolus. Medium length of ramus perforans is 51.7mm. After transition through the interosseous membrane, ramus perforans divides into ascending and descending branches. The diameter proximal to the level of bifurcation is 1.37 mm (variation 1.0-1.8 mm), and the diameter of the ascending branch distal to the level of bifurcation is 1 mm. Using CAMIA software, the medium length, width and area of the vascularization filed labeled with gentian violet were calculated to be 164 mm (variation 125-210 mm), 66 mm (57-77 mm), and 10,305 mm2 (6,385 mm2-14,341 mm2), respectively. Our results support the use of fasciocutaneous distal flap, vascularized by the ascending branch of the PARP for reconstruction of soft tissue defects in the distal third of the lower limb, malleolar regions and dorsum.
