Repair of lateral calcaneal wound with the lateral supramalleolar flap pedicled with the end perforator of peroneal artery / 中华显微外科杂志

To explore the method and effect of repairing the soft tissue defect of the lateral heel with the retrograde lateral supramalleolar flap pedicled with the end perforator of peroneal artery. Methods From May, 2015 to February, 2018, 16 cases of lateral calcaneal soft tissue defect were repaired with the retrograde lateral supramalleolar flap pedicled with the end perforator of peroneal artery.All wounds were treated with one-stage dilata-tion and VSD to control infection. In cases of chronic calcaneal bone infection, the bone defect formed after extensive resection of infected bone was temporarily filled with antibiotic bone cement. The area of soft tissue defect on the lat-eral heel was 3.0 cm×2.0 cm-8.0 cm×5.0 cm, and the area of flaps was 3.5 cm×2.5 cm-8.5 cm×5.5 cm. The small donor area of the flap was sutured directly, and the larger area was repaired by skin grafting. Patients with chronic calcaneal bone infection underwent bone cement removal and autogenous bone transplantation after inducing mem-brane formation 6 to 8 weeks after flap transplantation. All cases were followed-up, including 7 cases outpatient fol-low-up and 9 telephone follow-up. Results All the 16 flaps survived smoothly. The donor and recipient areas of the flaps healed primarily. All cases were followed-up for 3 to 13 months. The flaps had good shape, no swelling, similar color to heel skin and no pigmentation.Ankle flexion and extension were not restricted.Four cases with chron-ic osteomyelitis of calcaneus healed well after second-stage bone grafting, with an average healing time of 8.5 months. Conclusion The retrograde lateral supramalleolar flap with the end perforator of peroneal artery is an ideal method for repairing the soft tissue defect on the lateral heel with simple operation and reliable blood supply.

Soft Tissue Reconstruction of the Foot Using the Distally Based Island Pedicle Flap after Resection of Malignant Melanoma

BACKGROUND: We report on our experience with using a distally based island flap for soft tissue reconstruction of the foot in limb salvage surgery for malignant melanoma patients. METHODS: A distally based sural flap was used for 10 cases for the hindfoot reconstruction, and a lateral supramalleolar flap was used for 3 cases for the lateral arch reconstruction of the mid- and forefoot after wide excision of malignant melanomas. RESULTS: The length of the flap varied from 7.5 cm to 12 cm (mean, 9.6 cm) and the width varied from 6.5 cm to 12 cm (mean, 8.8 cm). Superficial necrosis developed in four flaps, but this was successfully treated by debridement and suture or a skin graft. All thirteen flaps survived completely and they provided good contour, stable and durable coverage for normal weight bearing. CONCLUSIONS: The distally based sural flap is considered to be useful for reconstructing the hindfoot, and the lateral supramalleolar flap is good for reconstructing the lateral archs of the mid- and forefoot after resection of malignant melanoma of the foot.

Subcutaneous Fascial Pedicled Lateral Supramalleolar Flap

Soft-tissue reconstruction of the foot and ankle has long been a challenge for reconstructive surgeons. Limitations in the available local tissue and donor-site morbidity restrict the options. In an effort to solve these difficult problems, the authors have begun to use a subcutaneous fascial pedicled lateral supramalleolar flap. This report presents the authors' experience with five patients treated with this flap. The patients' ages ranged from 26 to 72 years; four of the patients were male and one was female. The cause of the soft-tissue defects involved acute trauma and malignant melanom. All flaps survived and provided satisfactory coverage of the defect. Compared with the classic lateral supramalleolar flap, when the perforating branch is interrupted in its course, it is possible to elevate this subcutaneous fascial pedicled flap. The distally based flap with a compound pedicle which is continuous with a vascular axis and a band of subcutaneous fascial pedicle has long pedicle. This procedure is valuable for remote defect of the foot. It is believed that this flap is versatile and effective and is a good addition to the available techniques used by reconstructive surgeons for coverage of the foot and ankle.

One-stage Reconstruction of Soft-tissue Defect including Achilles Tendon: A Case Report / 대한정형외과학회잡지

Open defect of the Achilles tendon with loss of overlying skin is very difficult to treat. This condition poses problems of combating infection, providing soft-tissue cover and bridging the gap in the tendon. This has been generally managed in multi-staged procedures. Once the infection is brought under control with debridement and antibiotics, skin cover is provided by the flap. The tendon itself is reconstructed later by a conventional technique. More recently, composite free-tissue transfers repairing the skin and tendon in a single stage have been reported. We describe a simple and very reliable one-stage procedure, using a lateral supramalleolar island flap, a fascia lata autograft and a peroneus brevis tendon transfer, which helps tendon units bridge the gap in the Achilles tendon, and thin and mobile skin to cover the defect in the skin. Our patient showed good result, so we report this case with a review of the literature.

Proximal Tibia Opening Wedge Osteotomy for Treatment of Genu Recurvatum after Ipsilateral Femoral Shaft Fracture / 대한정형외과학회잡지

In 1988, a new fascioutaneous flap, the Lateral supramalleolar flap, was introduced by Masquelet and Roman. The flap is designed on the lower third of the aspect of leg, and supplied by a cutaneous branch from the perforating branch of the peroneal artery. This perforating branch continues distally deep to the fascia along the anterior ankle and into the foot. This can be use as either proximally based rotation flap or distally based reversed pedicle island flap giving the flap an arc of rotation that allows coverage of the dorsal, lateral and plantar aspects of the foot, the posterior heel and the lower medial portion of the leg. The authors have recently used this flap for 13 cases of foot and ankle soft tissue defect reconstruction and all the cases, except two partial marginal necrosis, good postoperative course. In our opinion, this flap is useful for reconstruction of foot and ankle soft tissue defect which does not need nerve innervation. The main advantages of the flap are as follows 1. It may be a rather large flap(15×9cm2 ). 2. The pedicle is long(8cm) and easy to dissect. 3. The pivot of the pedicle is distal(sinus tarsi) and allows great local possibilities of coverage. 4. It does not require the sacrifice of a main artery.

Lateral supramalleolar flap.

Soft tissue coverge of the heel and ankle area is one of the most difficult problems encountered in reconstruction particularly when the major arterial trees of the lower extremity are injured. Lateral supramalleolar flap, an axial pattern skin flap, based on the cutaneous branch of the perforating branch of the peroneal artery, can be effectively utilized as a mean of resolution. Sacrifice of the main arteries (anterior, posterior tibial artery, or peroneal artery) is avoided, which is the great advantage of this flap. Twelve patients, ages 8 to 55 years, underwent the operation employing this type of flap. Four cases of soft tissue lost on the foot, were covered with such flaps. The flap healed satisfactorily except for two cases, one had minor skin slough at the edge of the flap and the other one had necrosis of one had necrosis of one third of the flap, requiring subsequent debridement, but healing took spontaneously. The only one disadvantage of this flap is the donor site scar.
