Reconstruction of the replanted hand with latissimus dorsi muscle and serratus anterior fascia combined flap

Reconstruction with the latissimus dorsi muscle flap, combined with the serratus anterior fascia flap, was performed to cover two large and separate palmar and dorsal forearm skin defects in a patient, whose hand had been replanted 20 days earlier after traumatic amputation at the distal forearm level. As a result, a total forearm amputation was salvaged by microsurgical replantation and a free combined flap of the subscapular system. This new application of the combined flap allowed the reconstruction of large and separate wounds of the replanted hand, and provided gliding surfaces for tendons.

Reverse sural island flap elevated from the proximal third of the leg: its reliability and versatility in distal leg and foot reconstruction

Soft tissue loss around the distal third of the leg and foot has remained a considerable challenge. A reconstructive option providing supple tissue, while avoiding the complexity and the high technical demand of free flaps is a welcome alternative. The sural island flap largely satisfies these criteria. A number of authors have suggested raising the skin island from the junction of the middle and upper third of the leg to improve its reliability. However, raising the flap over the upper third of the leg may provide a larger amount of tissue and often makes dissection of its most distal perforator unnecessary. This study aims to assess the reliability and versatility of the reverse sural island flap elevated from the proximal third of the leg for soft tissue reconstruction of the distal leg and foot. Consecutive patients with soft tissue loss around the distal third of the leg and the ankle region requiring flap cover who met the inclusion criteria were managed using the distally based sural island flap elevated from the upper third of the leg. The outcome has been analysed. There were 15 patients, 11 males and four females with an age range of 22 to 54 years. Thirteen patients had distal third open tibial fractures while two had open calcaneal injuries. Nine resulted from motorcycle accidents, four from motor vehicular accidents while two were gunshot wounds. Flap sizes ranged from 10 × 7 cm to 22 × 12 cm. Thirteen flaps had full survival while two flaps had partial necrosis. All donor sites were skin grafted with 95% to 100% graft take. The use of the reverse sural island flap elevated from the proximal third of the leg for coverage of soft tissue defects of the distal leg and foot is safe and reliable in our experience. It provides a sizeable amount of soft tissue while maintaining a robust blood supply.     

Fasciocutaneous flaps in reconstruction of soft tissue defects below the knee

Reconstruction of soft tissue defects of the lower leg from 1966-2003, using fasciocutaneous flaps is discussed in this paper. Our experience with soft tissues defects in 69 patients is shown here. Different types of fasciocutaneous flaps were used (proximally and distally based fasciocutaneous flap, island, fasciosubcutaneous) based on septocutaneous perforators of all 3 main arterial trunks of the lower leg. We had complete or almost complete necrosis in only 4 patients, whereas in other patients flaps survived. Results obtained using fasciocutaneous flaps, even in reconstruction of war wounds convinced us that fasciocutaneous flaps are reliable method of reconstruction of the soft tissue defects of the lower leg, especially its distal third and regions of malleoli.     

The posterior tibial artery perforator flap: an alternative to free-flap closure in the comorbid patient

Wounds of the distal third of the leg with exposed bone traditionally require free flaps for coverage. Although this often provides good results, patients with multiple comorbidities cannot undergo the long operating times and multiple surgical sites required for these complex procedures. We reviewed the use of posterior tibial (PT) perforator flaps as an alternative to free flaps for distal leg wound coverage in ill patients. Six patients (mean age, 53 years) with multiple comorbidities that precluded free-flap closures were treated with PT perforator flaps to cover complex distal leg wounds. The most common comorbidity was cardiac disease. Five patients had Gustilo grade IIIB open tibial fractures and one had a chronic wound. Mean flap size was 8x5.5 cm with a mean of one perforator per flap. Mean operating room time was 103 minutes. Four flaps were done without general anesthesia. There were no perioperative cardiopulmonary events. With a mean follow-up of 15 months, all flaps survived and all patients were ambulatory. There were no cases of malunion, nonunion, infection, wound breakdown, or partial flap loss. The PT perforator flap is a reliable choice for patients with open leg wounds and comorbidities precluding free-flap closure.     

Wound coverage considerations for defects of the lower third of the leg

Anatomical features of the lower third of the leg like subcutaneous bone surrounded by tendons with no muscles, vessels in isolated compartments with little intercommunication between them make the coverage of the wounds in the region a challenging problem. Free flaps continue to be the gold standard for the coverage of lower third leg wounds because of their ability to cover large defects with high success rates and feasibility of using it in acute situations by choosing distant recipient vessels. Reverse flow flaps are more useful for the coverage of the ankle and foot defects than lower third leg defects. The perforators in the lower third leg on which these flaps are based are often damaged during the injury. In medium-sized defects of less than 50 cm² size, local transposition flaps, perforator flaps, or propeller flaps can be used. Preoperative identification by the Doppler is essential before embarking on these flaps. Of the muscle flaps, the peroneus brevis flap can be used in selected cases with small defects. In spite of all recent developments, cross-leg flaps continue to remain as a useful technique. In rare occasions when other flaps are not possible or when other options fail it can be a life boat. In the author''s practice free flaps continue to be the first choice for coverage of wounds in the lower third leg with gracilis muscle flap for small and medium defects, latissimus dorsi muscle flap for large defects and anterolateral thigh flap when a skin flap is preferred.KEY WORDS: Free flaps, perforator flaps, lower leg defects     

Soft-tissue reconstruction of an open tibial wound in the distal third of the leg: a new treatment algorithm

Over the past 4 years, a total of 33 patients, each with an open tibial wound in the distal third of the leg, underwent a skin-grafted muscle flap reconstruction according to the new treatment algorithm developed by the author. When the size of the soft-tissue defect was less than 50 cm, a pedicled medial hemisoleus muscle flap was used for the soft-tissue coverage (n = 20). If the soleus muscle was traumatized, a small free muscle flap (ie, gracilis) was then used (n = 3). When the size of the soft-tissue defect was greater than 50 cm, a larger free muscle flap (ie, rectus abdominis or latissimus dorsi) was selected (n = 10). All patients were followed for up to 4 years. Three patients with a medial hemisoleus muscle flap developed insignificant distal flap necrosis and were treated subsequently with debridement and flap advancement. Five patients with a free muscle flap required an additional operation, and 2 patients had a subsequent debulking procedure of the flap for contour improvement of the leg. Reliable soft-tissue coverage with a well-healed tibial wound, evident fracture healing, and good contour of the leg were achieved in all 33 patients during follow-up. Following this new treatment algorithm, a selected option for an open tibial wound in the distal third of the leg can provide reliable soft-tissue coverage for different sizes of open tibial wounds and may offer a more cost-effective approach for managing such a complex clinical problem.     

Reverse sural artery flap: caveats for success

Complex open wounds of the distal third of the leg and ankle remain a reconstructive challenge for the plastic surgeon. In many cases, these wounds are best addressed with a free tissue transfer. Although this group has performed more than 400 free flaps to the leg during the past 6 years, free tissue transfer can be an arduous operation that requires a team approach and substantial donor site morbidity for the patient. In recent years, the authors have favored the reverse sural artery fasciocutaneous flap in 11 patients for its ease of dissection, limited morbidity, and preservation of major vessels to the limb. Caveats for successful performance of the reverse sural artery flap include Doppler evidence of patent peroneal perforators, placement of a lazy T-shape skin paddle over the distal gastrocnemius muscle bellies, inclusion of the lesser saphenous vein to augment venous drainage, and, lastly, careful dissection to provide a wide adipofascial pedicle.     

Reverse fasciosubcutaneous flap versus distally pedicled sural island flap: two elective methods for distal-third leg reconstruction

In case of soft-tissue injury to the distal third of the leg, a safe and effective repair technique should be adopted. The use of complex procedures such as free flaps and cross-leg flaps is not always advisable. The authors present two methods that have proved to be both reliable and effective in obtaining long-lasting satisfactory results: the reverse fasciosubcutaneous sural flap and the reverse fasciocutaneous island sural flap. Since 1992 the authors have operated on 25 patients affected by traumatic tissue loss of the distal third of the leg and the calcaneal region. They used the fasciosubcutaneous flap in 14 patients and the sural flap in 11. Both of these flaps are technically simple, safe, and effective, and cause minimal injury to the donor site. The sural flaps are more useful for moderate-size wounds, especially in the calcaneal region, whereas the fasciosubcutaneous flap is better for repairing larger lesions of the leg and the ankle.     

The laterally extended medial hemisoleus flap for reconstruction of a tibial wound in the distal third of the leg

A soleus flap as a local reconstructive option for soft-tissue coverage of a tibial wound in the distal third of the leg has never been well recognized. In a 2-year period, seven patients underwent reconstruction of a less extensive tibial wound (4 × 3 to 10 × 4 cm) in the distal third of the leg after orthopedic trauma with the laterally extended medial hemisoleus flap. The flap was elevated with emphasis on the preservation of the most distal perforators from the posterior tibial vessels to the flap as possible while allowing adequate rotation of the flap to cover the exposed tibia and/or hardware and on the possible preservation of foot planter flexion by reconstruction of the proximal Achilles’ tendon. In this series, there was no total or partial flap loss. All patients healed their tibial wounds primarily with reliable soft-tissue coverage, evidenced fracture healing, and good cosmetic outcome during follow-up. Thus, the laterally extended medial hemisoleus flap described by the author can be a reliable option for soft-tissue coverage of a less extensive tibial wound in the distal third of the leg. It offers a more cost-effective approach for managing this unique problem and can be performed by most reconstructive surgeons without microsurgical expertise.     

Distally based posterior tibial artery perforator flap for coverage of defects around the ankle,heel and lower third of leg

Introduction

Reconstruction of distal leg region remained a difficult task. Free flaps had long been considered as a gold standard for these regions. However, due to various limitations of the free flap, a local fasciocutaneous flap could be considered as a good alternative. In this study, the use of a distally based posterior tibial artery perforator flap had been evaluated in the coverage of defects around the ankle, heel, and lower third of a leg. The study also outlined the donor-site morbidity and the technical details of the surgical procedure.

Methods

In this prospective study, a total of 42 patients with distal lower leg defects were included. The defects were located on the lower third of the leg (n?=?23), ankle (n?=?11), and heel (n?=?8). Reconstruction was performed using distally pedicled posterior tibial artery perforator flaps. Patients were evaluated in terms of viability of the flap, functional gain, and donor-site morbidity. The technical details of the operative procedure have also been outlined.

Results

All the flaps survived well, with the exception of one patient, who experienced complete flap loss. Minor complications were, however, noted in four other patients: One patient developed superficial epidermolysis; one developed postoperative venous congestion, which subsided within 3 days by conservative means, and in two patients, partial loss of the skin graft occurred at the donor site but healed completely with dressing and antibiotics. The patients were followed up for an average period of 6 months, ranging from 1 to 13 months. Donor-site morbidity was minimal.

Conclusions

It was concluded that the distally based pedicled posterior tibial artery perforator flap was a reliable, easy, less time-consuming, and versatile procedure for covering the defects around the ankle, heel, and lower third a leg. Level of Evidence: Level IV, therapeutic study     

The reversed medial hemisoleus muscle flap and its role in reconstruction of an open tibial wound in the lower third of the leg

The usefulness of a reversed hemisoleus muscle flap as a local reconstructive option for soft-tissue coverage of an open tibial wound in the lower third of the leg has never been acknowledged. Over the past 2 years, 8 patients underwent soft-tissue reconstruction of an open tibial wound (3 x 3 to 10 x 6 cm) in the lower third of the leg with the reversed medial hemisoleus muscle flap modified by the author. The flap was dissected with attention to preserve several critical perforators from the posterior tibial vessels to the flap as possible while allowing adequate turnover of the flap to cover the exposed tibia or hardware. There was no total flap loss, and limb salvage was achieved in all patients. Only 2 patients developed insignificant distal flap necrosis, and they were treated subsequently with debridement and flap readvancement. All patients had reliable healing of their tibial wounds, with good reconstructive and cosmetic outcomes of their flap reconstructions during follow-up. Therefore, the author believes that the reversed medial hemisoleus muscle flap can be a good choice for soft-tissue coverage of a sizable open tibial wound in the lower third of the leg and may be used successfully to replace free tissue transfer in selected patients.     

Lip reconstruction in noma sequelae

Noma is a grangenous stomatitis which might extend to other facial structures leading to extensive soft tissue and bony defects. Reconstruction of noma sequellae should take into account a few principles in relation to the particular aspect of this disease: (1) correction of the mandibular constriction; (2) removal of scar tissue in order to recreate the initial defect; (3) reconstruction of the missing bony framework; (4) reconstruction of the maxilla and upper lip before building the nose in case it is destroyed; (5) anticipation of the facial growth. Reconstruction of the lips, in case of extensive defects often necessitates a distant skin flap. As free flaps, the forearm fascio-cutaneous flap or the serratus musculo-cutaneous flap were used according to the size of the defect. The mucosal part of the lip is usually reconstructed with a local flap from the adjacent lip or an heterolabial flap (Estlander flap).     

Transverse splitting of the gracilis muscle free flap: Maximal use of a single muscle

The gracilis muscle, based on the dominant pedicle, has been used extensively for free tissue transfer. Recent studies have described the constant anatomy, ease of dissection, and low donor-site morbidity of the distal segmental gracilis free muscle flap. We present three cases of free distal segmental gracilis muscle transfer. In one case, the gracilis muscle was divided transversely into one proximally based and one distally based free flap and used for coverage of two separate wounds in a patient with bilateral open calcaneal fractures. In two cases, the preserved proximal gracilis was used as a reoperative free flap after failure of the initial distal segmental gracilis free muscle. With recent advances in microsurgery and ever-growing demands for low donor-site morbidity, it is important to ensure each free muscle flap harvested is used efficiently. Use of the free distal segmental gracilis muscle flap maximally uses one muscle while minimizing donor site morbidity and retaining the proximal muscle for future uses.     

The cross-leg flap: still a useful flap in children.

Reconstruction of the distal lower limb and foot is a difficult problem, especially where large areas of skin loss have occurred. The cross-leg flap is a safe and reliable alternative to free tissue transfer in paediatric lower limb trauma. By incorporating fascia or muscle the versatility of the flap can be enhanced. Our experience with the cross-leg flap in children during the last 5 years is discussed.     

Pedicled neurocutaneous anterolateral thigh flap for groin reconstruction – A case report

Several different flaps based on the feeding vessels of sensitive nerves have been described in the limbs. This article reports the case of a neurocutaneous flap based on the lateral femoral cutaneous nerve (LFCN), employed for reconstruction of an inguinal defect. A 61‐years‐old female patient had undergone vulvectomy and bilateral inguinal lymphadenectomy for vulvar cancer with postoperative left groin wound breakdown. After a 3 weeks negative pressure therapy course, she presented a 10 × 4 cm skin and subcutaneous defect with undermined edges in the left inguinal area. Reconstruction with 14 × 6 cm pedicled left anterolateral thigh flap was planned. After the dissection of the vascular pedicle and of the sensitive nerve, complete thrombosis of both the veins and arterial spasm of perforating pedicle was detected. As the flap color was good, and slow marginal bleeding was present, we inspected the small vessels surrounding the nerve that were pulsating. To confirm the vascularization coming from the neural pedicle, we clamped the perforator and performed intraoperative indocyanine green (ICG) fluorescence angiography that showed a good fluorescence of the flap with a proximal to distal pattern of progression. The flap was transferred on the neural pedicle, survived completely, and wounds healed normally. Three months after surgery, the patient underwent radiotherapy, with uneventful course. In her last follow‐up, 2 years after surgery, patient was free of disease and the flap showed normal scarring. This is the first case reported of a pedicled neurocutaneous flap based on the LFCN, indicating that in case of unsuitable perforators it could be an alternative pedicle.     

First web space post-burn contracture types: Contracture elimination methods

First web space adduction contractures are a common consequence of hand burns. Many reconstructive techniques are used and investigation for more effective methods continues. Effective hand reconstruction usually considers anatomy as its foundation. Based on the experience of over 500 web space contracture elimination cases, three anatomical types of thumb adduction contractures were identified: edge, medial and total. Edge contractures (80% of all thumb adduction contractures) are caused by a fold in which only one sheet is scarred, either the palmar or dorsal surface. The contraction is caused by a trapeze-shaped length deficiency of the scar sheet, which has a surface surplus in width. Reconstruction consists of surface deficiency compensation with trapezoid flap prepared from the non-scarred side and skin-fat tissues of the web space. In most cases, the small scar-fat trapezoid flaps should be prepared from the non-scarred side to cover the donor wounds on both sides of the main flap. Medial contractures (10% of thumb adduction contractures) are caused by the fold, both sheets of which are scarred and have trapeze-shaped surface deficiency in length and surplus in width. Both fold sheets are converted into one or several pairs of trapezoid scar-fat flaps by radial incisions. The oppositely located flaps are transposed towards each other. As a result of the counter flaps transposition, the contracture is eliminated; the web space's shape and depth are restored by the use of flaps alone or in combination with skin grafting. The trapeze-flap plasty is very simple and effective with the length gain of up to 100-200%. Neither flap loss nor re-contracture occurs. Total contractures (about 10% of all) have no fold. Reconstruction consists of the creation of the central zone of the first web space depth with the rectangular subdermal pedicle flap; the wounds on both sides of the flap are skin grafted. The flap sustains normal web depth and prevents the contracture recurrence and skin graft shrinkage.     

Lappenplastiken zur Defektdeckung am distalen Unterschenkel

Soft tissue defects in the distal lower leg region are challenging to treat, especially in trauma cases. To achieve early closure of the defect, pediculated adipofascial or muscle flaps can be used as well as free flaps. The pediculated adipofascial suralis flap has a reliable blood supply and a broad radius so this flap can be used for almost every defect location on the distal lower leg except for defects larger than 10?×?10 cm. The donor site defect does not lead to major problems and is well tolerated. The soleus flap can cover defects in the middle third and proximal distal third of the lower leg with its muscle. The donor site defect is occasionally associated with reduced calf functioning but is tolerated well most of the time. Because of these advantages, the pediculated adipofacial suralis flap and the soleus muscle flap can be used instead a microvascular free flap for the closure of defects in the distal lower leg region.     

Peroneus brevis rotation flap: anatomic considerations and clinical experience

BACKGROUND: Large soft tissue defects of the distal third of the leg are common occurrences at trauma centers. Massive defects often require vascularized free tissue transfer for coverage; however, smaller defects may frequently be closed by rotation of local tissue. The peroneus brevis muscle is ideally located to provide coverage of the exposed distal fibula. METHODS: An anatomic dissection of the peroneus brevis muscle and its vascular pedicles was performed in 10 fresh cadaveric leg specimens. Patients who underwent this procedure at our institution were retrospectively reviewed. RESULTS: Each dissected muscle had an average of 3.5 vascular pedicles (range, 2-6), which arose from the peroneal artery in all but two cases. The average distance of the distal pedicle from the tip of the lateral malleolus was 6.7 cm (range, 3.5-12.0 cm). The muscle belly ended an average of 6.0 mm proximal to the tip of the lateral malleolus. Half of the specimens had muscle bellies that extended to or past the tip of the lateral malleolus. This rotation flap has been successful in covering four wounds with exposed distal fibula in four patients. CONCLUSION: The anatomic characteristics of the peroneus brevis muscle are ideal for soft tissue coverage of the distal fibula. Ease of elevation and reliability have made this rotational flap the procedure of choice for small soft tissue defects over the distal fibula at our institution.     

The lateral arm free flap in lower extremity reconstruction

Reconstruction of skin defects of the distal third of the leg and foot is often a difficult task. Shape, resistance to shearing stresses in the weight-bearing surface and sensibility are the main features that have to be restored. For coverage of this region, the authors have used, in selected patients, the lateral arm flap (LAF) since 1994. This flap is thin, easy to dissect and has the possibility to be innervated through the posterior cutaneous nerve of the arm. Fourteen cases are presented. The drawbacks of this flap are the loss of sensibility in the forearm (partially transient) and the scar on the arm, which can be rather unsightly in young ladies and when big flaps are harvested skin graft is needed.
