Grafts/flaps

In this report, we present our experience on the use of the reverse sural flap for traumatic foot and ankle reconstruction. The patient selection and surgical refinement are discussed. From 2007 to 2010, 11 consecutive patients underwent modified reverse sural flap at the Chang Gung Memorial Hospital. The defects were located at the ankle (three cases), foot (two cases), and heel (six cases). Particular attention was paid to precise patient selection and surgical refinements. Patient selection was based on the lower limb vascular status by palpable distal pedal pulses and ankle brachial index ranging from 0...

OBJECTIVE: Defect coverage especially in exposed bone of the lower leg by pedicled muscle flaps in association with a split-thickness skin graft. Defect coverage oropharyngeal or at the upper extremity by free soleus flaps. INDICATIONS: Defects of the proximal and middle thirds of the anterior lower leg for the proximally pedicled soleus flap; defects of the middle and distal third of the anterior lower leg for the distally pedicled soleus flap. The free flap is almost ubiquitously useable...

This ultrasound study investigated the frequency, location, and diameter of segmental blood supply of 34 lower legs in relation to muscle size. Furthermore, we investigated the possibilities and constraints of distally pedicled peroneus brevis muscle flaps, which allow defect coverage down to the medial as well as the lateral ankle. In the proximal part of the peroneus brevis muscle, blood is supplied by branches from the anterior tibial artery that perforate the anterior intermuscular septum; in the distal part of the muscle, blood is supplied by branches from the peroneal artery that perforate the posterior intermuscular septum...

BACKGROUND: Peripheral vascular disease and/or diabetic neuropathy represent one of the main etiologies for the development of lower leg and/or diabetic foot ulcerations, and especially after acute trauma or chronic mechanical stress. The reconstruction of such wounds is challenging due to the paucity of soft tissue resources in this region. Various procedures including orthobiologics, skin grafting (SG) with or without negative pressure wound therapy and local random flaps have been used with varying degrees of success to cover diabetic lower leg or foot ulcerations...

Skin grafting provides an efficient way for diabetic wound closure when standard conservative therapy has failed and primary surgical closure is not an option. Pinch grafting provides an alternate method that can provide durable closure for soft tissue loss in the diabetic foot. An overview of this technique and its indications for diabetic foot wounds is presented.

A wide array of reconstructive options exists for soft tissue coverage of diabetic foot wounds; however, each case depends on the patient's medical comorbidities, wound type, anatomy of the affected site, and level of contamination. Although autologous skin grafts have traditionally played a pivotal role in the coverage of diabetic wounds, several advanced biological skin substitutes have become available, providing surgeons with additional choices in the management of these challenging wounds. This article reviews these surgical modalities by presenting indications for every option and clinical scenario that may benefit from their combined use...

The efficacy and durability of wound closure was examined in a prospective randomized unbalanced clinical trial using the application of a living serum-free cultured epidermal autograft in conjunction with wound-area debridement and a four-layer compression wrap (N=10) compared with wound-area debridement and a four-layer compression wrap in patients with hard-to-heal leg ulcers arising from confirmed venous stasis (N=5). All 15 patients who presented with full-thickness venous ulceration were treated weekly for 8 weeks, with a 12-week final evaluation...

A biologically active human skin allograft, currently distributed under the brand name TheraSkin(®), was examined for safety and efficacy in the treatment of venous leg ulcers (VLUs) and diabetic foot ulcers (DFUs). The objective was to determine if TheraSkin could serve as a safe and effective alternative to bioengineered skin substitutes such as Apligraf(®) and Dermagraft(®). The authors conducted a retrospective study of 214 consecutive patients seen at the Inova Wound Center (Mt Vernon, Virginia), with either a DFU or a VLU...

In some cases, the fibula osteocutaneous flap may not provide sufficient soft tissue for obliterating dead space after tumor ablation. This report describes a modified fibula osteocutaneous flap using a portion of soleus muscle to reduce postoperative complications. This study analyzed 20 patients who underwent ablative oral cancer surgery with mandibular segmental defect between September 2005 and June 2007. Of total, 17 cases were mandible complex defects and 3 were composite defects. Of total, 18 were men and 2 were women, respectively...

OBJECTIVE: To compare healing rates of inpatients and outpatients with chronic leg ulcers treated with pinch grafting and to define which of these patients would benefit most from the therapy. METHOD: This retrospective analysis reports the healing rates of 104 patients with 169 ulcers treated with pinch grafting during 1997-2007 at the Department of Dermatology, Tampere University Hospital. RESULTS: These relate to 17 outpatients with 18 pinch-grafted ulcers and 95 inpatients with 151 ulcers...

BACKGROUND: Defects of the distal third of the lower leg with exposed tendons or bone require either local or free flap coverage. Several flaps have been developed, and the distally pedicled peroneus brevis muscle flap has been proven to be a valid local flap alternative. PATIENTS AND METHODS: Peroneus brevis muscle is dissected from the lateral surface of the fibula from proximal to distal, but no further than approximately 3-6 cm proximally to the lateral malleolus, where the most distal vascular pedicle from the peroneal artery enters the muscle consistently...

BACKGROUND: Data regarding donor-site morbidity, postoperative clinical course, and functional and aesthetic outcome after gastrocnemius muscle flaps are rare. METHODS: Data regarding 218 consecutive patients treated with gastrocnemius muscle flaps were acquired from patients' charts and from contact with patients, with special reference to treatment and clinical course. Eighty-two were interviewed with a standardized questionnaire, 40 were examined physically, and 34 underwent dynamometric muscle function tests...

Various types of neurocutaneous flaps have been used for extremity reconstructions. However, the application of this technique to the dorsum of the foot has not been reported previously. The aim of this article is to evaluate the attempts and clinical results from dorsal pedal neurocutaneous flap procedures. Harvesting of these flaps included the medial, intermediate and lateral dorsal cutaneous nerves, the deep peroneal nerve and the nutrient arteries of these nerves. The vascular anatomy of these flaps was studied before the clinical usage of the procedure...

BACKGROUND: Full thickness skin grafts (FTSGs) remain a good option for resurfacing defects of the face, neck, and dorsum of the feet. It results in soft, pliable, functional skin with minimal contraction. However, FTSG may result in patchy or irregular "take" resulting in recurrent contractures and pigmentary discrepancies. This study examines the use of a negative pressure dressing (NPD) to increase FTSG take. METHODS: Wounds resulting from trauma, postburn contracture release, and an excision of a congenital nevus were included in the study...

BACKGROUND: Chronic venous leg ulcers represent an urgent and increasing problem for public health. The use of skin autografts results in a greater therapeutic success in healing chronic ulcers. OBJECTIVE: A simple method of skin autografting that could permit a wider use of skin grafts in outpatients is needed. A new technique allowing skin autografting in a simple one-step process, without complex surgical procedures or expensive technical supplies, is presented...

BACKGROUND: Venous leg ulceration is a recurrent, chronic, disabling condition. It affects up to one in 100 adults at some time. Standard treatments are simple dressings and compression bandages or stockings. Sometimes, despite treatment, ulcers remain open for months or years. Sometimes skin grafts are used to stimulate healing. These may be taken, or grown into a dressing, from the patient's own uninjured skin (autografts), or applied as a sheet of bioengineered skin grown from donor cells (allograft)...

Wide, full-thickness defects on the posterior aspect of the distal lower leg involving the Achilles tendon are usually repaired with free fasciocutaneous flaps or local skin flaps. The former require microvascular techniques; there is a donor-site scar due to skin grafting; and a longer operating time. The latter results in a wide scar near the donor defect. The authors developed a new reconstructive procedure using local fascia turned over to create a new Achilles tendon, and wrapping it with a posterior tibial adiposal island flap based on the dominant perforator of the posterior tibial artery, which was elevated from the medial aspect of the lower leg...

BACKGROUND: Venous leg ulcers are a major cause of morbidity, economic loss, and decreased quality of life in affected patients. Recently, biomaterials derived from natural tissue sources have been used to stimulate wound closure. One such biomaterial obtained from porcine small-intestine submucosa (SIS) has shown promise as an effective treatment to manage full-thickness wounds. Our objective was to compare the effectiveness of SIS wound matrix with compression vs compression alone in healing chronic leg ulcers within 12 weeks...

BACKGROUND: It is common for traumatologists to see avulsion injuries with resulting composite skin flaps. Simply reattaching the avulsed flap by suturing it back into its bed may result in ischemic necrosis of the distal portion of the flap. CASE REPORT: The authors present a case in which an extensive avulsion injury of the dorsum of the foot with amputation of the fourth and fifth toe was treated by defatting the avulsed flap and reattachment as a full-thickness graft...

Resurfacing the glabrous skin covering the human plantar and palmar surfaces constitutes a challenge to the plastic surgeon. Ideally, when this skin is lost, it should be replaced by the same type of tissue to provide strength, texture, and color match. This paper describes our experience with 9 palmar and plantar wounds which were successfully resurfaced with pinch grafts harvested from the non-weight-bearing area at the medial plantar arch of the foot. The patients were allowed to ambulate after surgery with partial or full weight-bearing as tolerated, the donor sites healed in 7 to 9 days without complication, and pinch grafts took 100%...
