Celie KB, Guo S, Raya J, Fahradyan A, Carey J, Salibian AA. The cross-leg free flap: A systematic review of the literature. Microsurgery 2024; 44:e31144. [PMID: 38342999 DOI: 10.1002/micr.31144] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Revised: 11/07/2023] [Accepted: 12/19/2023] [Indexed: 02/15/2024]
Abstract
BACKGROUND Free tissue transfer is a mainstay treatment for lower extremity soft tissue injuries. When the traditional cross-leg flap cannot provide enough coverage, a cross-leg free flap (CLFF) is a limb-saving alternative. The aim of this study is to conduct a systematic review of the literature published on the CLFF. METHODS We conducted a systematic review of articles describing the CLFF, according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Inclusion criteria included articles with primary data on the CLFF. Exclusion criteria included those describing pedicled cross-leg flaps or lacking complete data. Data analysis was performed using SPSS 29.0. RESULTS Our review included 28 articles encompassing 130 patients who underwent free tissue transfer. Most were male (63.8%) with a mean age of 32.4 years. Latissimus dorsi was the most common flap type (30.0%), followed by vertical rectus myocutaneous (20.0%). Average flap size was 301.8 cm2 , with trauma in the lower third of the leg being the most common indication (73.1%). The contralateral posterior tibialis was the most common recipient artery (84.1%) followed by the anterior tibialis (9.5%). Complications included amputation (1.4%), partial graft loss, thrombosis, hematoma, prolonged pain, nonunion, and seroma; a forest plot was used to illustrate the low overall adverse events rate. Although bivariate analysis identified age, flap size, type, location, and donor site as variables significantly impacting the incidence of complications (p < .05), this was not sustained in a multivariate logistic regression model. CONCLUSION The CLFF remains an excellent option for limb salvage when a suitable recipient vessel is unavailable. Our review demonstrates 1.4% flap failure and an acceptable complication rate. While most cases in our review describe muscle flaps, we report a complex case of limb salvage using an unusually large anterolateral thigh flap.

The Autonomization Principle in Vascularized Flaps: An Alternative Strategy for Composite Tissue Scaffold In Vivo Revascularization. Bioengineering (Basel) 2023; 10:1440. [PMID: 38136031 PMCID: PMC10740989 DOI: 10.3390/bioengineering10121440] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Revised: 11/28/2023] [Accepted: 12/07/2023] [Indexed: 12/24/2023] Open
Abstract
Autonomization is a physiological process allowing a flap to develop neo-vascularization from the reconstructed wound bed. This phenomenon has been used since the early application of flap surgeries but still remains poorly understood. Reconstructive strategies have greatly evolved since, and fasciocutaneous flaps have progressively replaced muscle-based reconstructions, ensuring better functional outcomes with great reliability. However, plastic surgeons still encounter challenges in complex cases where conventional flap reconstruction reaches its limitations. Furthermore, emerging bioengineering applications, such as decellularized scaffolds allowing a complex extracellular matrix to be repopulated with autologous cells, also face the complexity of revascularization. The objective of this article is to gather evidence of autonomization phenomena. A systematic review of flap autonomization is then performed to document the minimum delay allowing this process. Finally, past and potential applications in bio- and tissue-engineering approaches are discussed, highlighting the potential for in vivo revascularization of acellular scaffolds.

Reliability and Safety of Cross-Leg Free Latissmus Dorsi Muscle Flap in Reconstruction of Mutilating Leg Injuries Using End-to-Side Anastomosis. Arch Plast Surg 2023; 50:507-513. [PMID: 37808335 PMCID: PMC10556300 DOI: 10.1055/a-2126-7058] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2022] [Accepted: 07/04/2023] [Indexed: 10/10/2023] Open
Abstract
Background Free tissue transfer is considered the gold standard option for the reconstruction of distal leg defects. Free tissue transfer using recipient vessels in the contralateral leg (cross-leg bridge) is a potential option to supply the flap if there are no suitable recipient vessels in the injured leg. Most studies have described this technique using end-to-end anastomosis which sacrifices the main vessel in the uninjured leg. This study evaluated the use of a cross-leg free latissimus dorsi muscle flap for the reconstruction of defects in single-vessel legs, using end-to-side anastomosis to recipient vessels in the contralateral leg without sacrificing any vessel in the uninjured leg. Methods This is a retrospective study that included 22 consecutive patients with soft tissue defects over the lower leg. All the reconstructed legs had a single artery as documented by CT angiography. All patients underwent cross-leg free latissimus dorsi muscle flap using end-to-side anastomosis to the posterior tibial vessels of the contralateral leg. Results The age at surgery ranged from 12 to 31 years and the mean defect size was 86 cm 2 . Complete flap survival occurred in 20 cases (91%). One patient had total flap ischemia. Another patient had distal flap ischemia. Conclusion Cross-leg free latissimus dorsi muscle flap is a reliable and safe technique for the reconstruction and salvage of mutilating leg injuries, especially in cases of leg injuries with a single artery. As far as preservation of the donor limb circulation is concerned, end-to-side anastomosis is a reasonable option as it maintains the continuity of the donor leg vessels.

Efficacy of a “provisional incision” for longitudinal flap division after free-flap surgery. JPRAS Open 2022; 34:64-72.

Abstract
Fix and flap surgery for severe open limb fractures is already a standard treatment. In cases where the fracture is complicated or accompanied by bone defects, secondary surgery is required for fracture sites covered with a myocutaneous flap after the soft tissue condition has stabilized. We applied the delayed procedure concept used for distant flaps and attempted to prevent postoperative myocutaneous flap necrosis by performing a provisional incision prior to the longitudinal incision of the flap. We report the course of five cases of the longitudinal division of the myocutaneous flap using “provisional incision” after free-flap surgery for severe open fracture and verify its usefulness. In this case series, five patients with severe open limb fractures treated from 2020 to 2021 who underwent longitudinal incision of the myocutaneous flap using provisional incision after free-flap surgery were included. The types of flaps used for soft tissue reconstruction in the acute phase, the reasons for the need for secondary surgery, the period from soft tissue reconstruction to additional surgery, and the healing status of soft tissue after secondary surgery were all investigated retrospectively. The types of flaps used for soft tissue reconstruction were latissimus dorsi myocutaneous flap in four cases and anterolateral thigh flap in one case. The breakdown of secondary surgery was osteosynthesis in one case, plate removal in one case, and bone cement removal and autologous bone grafting in three cases. The period from soft tissue reconstruction to secondary surgery ranged from 6 weeks to 4 months. In all cases, the wound healed without necrosis of the myocutaneous flap. For the treatment of severe open limb fractures, longitudinal division of the myocutaneous flap using “provisional incision” is a safer approach to the necessary secondary surgery and reduces the possibility of necrosis of the flap.

Abstract
BACKGROUND Distal lower limb reconstruction is one of the most difficult and challenging tasks in plastic surgery. Despite the continuous advances in microsurgical techniques, pedicled cross-leg flaps still have a major role particularly in pediatric patients. Many techniques have been described to maximize the potential of the cross-leg flaps. The introduction of fasciocutaneous flaps has provided more potentials and made lower leg reconstruction easier and more successful. The description of perforator system in the leg has also made a revolution in the regional reconstruction. In this report, we present a new modification that increases the reach and facilitates the inset of the flaps. METHODS The flap is taken from the posteromedial skin of the middle third of the leg. The design is determined by the location, size, and shape of the defect. The base of the flap should contain at least 2 perforators located by Doppler device. After elevation of the fasciocutaneous flap, 2 back cuts are performed in the upper and lower edge of the flap base preserving the 2 previously located perforators. RESULTS Fifty patients, 32 males and 18 females, were reviewed and presented. Age of the patients ranged from 4 to 13 years and the defect size ranged from 20 to 130 cm. All flaps survived with 3 flaps had mild marginal ischemia, 2 flaps had mild infection, and 1 flap had partial dehiscence. CONCLUSIONS Back cuts made at the edges of the base of a cross-leg flap, preserving the feeding perforators, can increase the flap reach without jeopardizing its viability. It is also an easy to do technique and does not require any extra equipment or time.

Abstract
Treatment of traumatic loss of bone and tissue substance in the foot necessitates special consideration of the anatomy and physiology of the segment. The causes of foot trauma are multiple and in many cases violent, leading to progressive tissue deterioration that may require multi-phased debridement. The therapeutic objective is to reconstruct a functional foot permitting painless pushing off, walking and footwear use by restoring a stable bone framework, with resistant covering satisfactorily adjusted to the different zones of the foot. While coverage of the back of the foot must be fine, coverage of the plantar zones will be padded. The reconstructive surgeon shall be particularly attentive to plantar sensitivity. To take up the surgical challenge, it is of paramount importance to fully master a wide-ranging therapeutic arsenal ranging from conventional grafts to composite free flaps in view of proposing the solution most suited to the type, size and location of the loss of substance, all the while striving to generate as few sequelae as possible at the donor site. In order for reconstruction to be successful, multidisciplinary collaboration between plastic surgeons, orthopedists and physician is highly recommended.

Abstract
When there is no suitable vessel in the injured leg for microsurgical transfer, cross-leg free flaps can be considered for lower extremity reconstruction. This report describes patients who experienced lower extremity trauma and underwent reconstruction with cross-leg free flaps with preserved blood flow in the recipient artery. Anterolateral thigh flap is preferred for small to moderate defects. The descending branch of the lateral femoral circumflex artery was dissected 2 cm proximally and distally and was prepared in a T-shape. The branches of the T were anastomosed to the recipient artery in the contralateral leg in the first session of the cross-leg free flap procedure. After 3 weeks, the flap artery was separated from the bifurcation. For large defects, the latissimus dorsi flap was chosen. The thoracodorsal artery was anastomosed to the contralateral posterior tibial artery in the first session. After 3 weeks, to provide recipient vessel integrity, the thoracodorsal artery was transected from the flap and anastomosed to the distal stump of the posterior tibial artery. Between January 2017 and January 2019, 8 defects were reconstructed using an anterolateral thigh flap; the remaining 4 defects were reconstructed using a latissimus dorsi flap. All flaps survived without complications. Anterograde flow distal to the anastomosis was confirmed in all recipient arteries via Doppler ultrasound. In cross-leg free flaps, the continuity of the recipient artery can be established to prevent diminished blood flow to the recipient extremity.

Abstract
Cross-leg flaps are a useful reconstructive option for complex lower limb defects when free flaps cannot be performed owing to vessel damage. We describe the use of the extended distally based sural artery flap in a cross-leg fashion for lower extremity coverage in three patients. To maximise the viability of these extended flaps, a delay was performed by raising them in a bipedicled fashion before gradual division of the tip over 5 to 7 days for cross-leg transfer. Rigid coupling of the lower limbs with external fixators was critical in preventing flap avulsion and to promote neovascular takeover. The pedicle was gradually divided over the ensuing 7 to 14 days before full flap inset and removal of the external fixators. In all three patients, the flaps survived with no complications and successful coverage of the critical defect was achieved. One patient developed a grade 2 pressure injury on his heel that resolved with conservative dressings. The donor sites and external fixator pin wounds healed well, with no functional morbidity. The cross-leg extended distally based sural artery flap is a reliable reconstructive option in challenging scenarios. Adequate flap delay, manoeuvres to reduce congestion, and postoperative rigid immobilization are key to a successful outcome.

Abstract
Gustilo Grade IIIB and IIIC open fractures of the lower extremity often involve complex wounds requiring bony fixation and soft tissue reconstruction. We present a case of a 32 year-old male who suffered a traumatic Gustilo Grade IIIB open fracture of the tibia and fibula with an extensive soft tissue defect. Reconstruction was first attempted with a turbocharged anterolateral thigh flap that failed due to venous thrombosis. Due to vascular injury, limited reconstructive options were available from the ipsilateral leg. Limb salvage was subsequently achieved with a chimeric cross-leg latissimus dorsi-serratus anterior (LD-SA) free flap based off the contralateral healthy leg, using the serratus for pedicle bridge coverage so that the latissimus could be fully used for defect coverage. Though not extensively described in the literature, this flap is a versatile reconstructive option for limb salvage in patients with Gustilo IIIB or IIIC injuries to the lower extremity.

Abstract
Limb salvage in an irradiated patient with limited recipient vessels leaves few options for reconstruction. Cross-leg free flaps have been used to reconstruct defects that would otherwise lead to amputation in patients with no ipsilateral recipient vessels. We present the first documented case of a cross-leg free flap for limb salvage in a radiated bed after infection and tumour resection.

Abstract
INTRODUCTION A muscle flap can survive a pedicle injury under favourable conditions. In the reconstruction of compound limb injuries, the wound milieu is variable and may affect the rate and manner of neovascularisation. Our aim is to determine the effect of some key clinical variables on neovascularisation in muscle flaps in an animal model. METHODOLOGY The pectoralis profundus was raised in 60 rats and covered with a skin graft. Fifteen rats were allocated to each of the following groups: separation of the flap from the skin inset (S), inflammation by inoculation with Staphylococcus aureus (I), flap elevation with harmonic scalpel (H) and preservation of the motor nerve (N) as well as compared to controls (C). Graft take and wound complications were assessed five days later, as well as perfusion before and after pedicle ligation, by laser Doppler flowmetry and neovascularisation using barium angiography. RESULTS Flaps with an intact motor nerve had significantly higher graft take than controls (59% vs 29%). Perfusion change was lesser in all study groups than in controls, although the extent of flap necrosis was not significantly different. Only flaps raised with the harmonic scalpel generated more new vessels than controls at the inset (9.6 vs 3.2), particularly at the origin of the muscle (1.10 vs 0.19). CONCLUSIONS All study groups were less dependent on their pedicle for perfusion than controls. The use of the harmonic scalpel and increased inflammation seem pro-angiogenic, although they do not reduce flap necrosis after simulated pedicle injury. Neovascularisation will preferentially bridge to the skin at the inset rather than tissues in the base of the wound. It is likely that flap necrosis is the result of a combination of unfavourable variables rather than one in isolation.

Abstract
BACKGROUND In the experience of our centre, 33% of reconstructed compound lower limb injuries will need an orthopaedic revision.1 A flap may be re-raised through numerous methods, and historically, the approach of choice has been based on the principle of protecting the vascular pedicle rather than the inset. Our aim was to determine whether a marginal versus a split approach to re-raising inferred a higher risk of flap necrosis and whether more attention should be paid to protecting the inset of the flap, particularly at the distal portion. METHOD A pedicled pectoralis profundus muscle flap was raised in 32 Sprague-Dawley rats and transposed to the lateral chest wall. After 21 days, the flaps were randomised into one of four treatment groups according to the surgical approach and whether or not the anatomical vascular pedicle was ligated. Necrosis was assessed 48 h later, both clinically and through the analysis of digital photographs. RESULTS The rate of necrosis in the marginal group was higher than that in the split group (63% vs 0%, p < 0.001, McNemar). More necrosis occurred in the former when the pedicle was ligated (p < 0.001, Fisher's exact test). Measured necrosis was also higher in the marginal group (18% vs 0%, p = 0.002, Wilcoxon signed-rank test). Twenty-nine percent more flap could be raised using the split approach (p = 0.001, Mann-Whitney U test). CONCLUSIONS Splitting a muscle flap produces significantly less necrosis than incising the inset, regardless of whether the pedicle is in flow. It also offers wider exposure of structures deep to the flap. These findings provide a detailed model for human trials, which is presented as a proposed management algorithm. It also highlights conditions that must be met for translation to a human population.

Abstract
INTRODUCTION Free muscle flaps are being used more commonly for complex lower limb reconstruction. Up to 33% of flaps used to reconstruct lower limb trauma will require an orthopaedic procedure after reconstruction. To date there have been only case reports detailing the variable survival of muscle flaps after actual or simulated pedicle injury and the process and timeframe of neovascularisation remains undefined. We aim to show that perfusion of a muscle flap is possible after injury to its anatomical vascular pedicle. METHODS Pedicled muscle flaps were raised and transposed to a cutaneous inset on the chest wall in a rodent model. Each flap was subjected to simulated pedicle injury at a variable time. Allocation was by computer randomisation. Flap perfusion was assessed before and after pedicle injury followed 48 h later by sacrifice of the animal and static angiography of the flaps. RESULTS By the 21st day after inset, all flaps survived simulated pedicle injury. Prior to this, flap survival was significantly lower (p = 0.017, Fisher's Exact Test). Clinical signs at the time of pedicle injury did not predict flap survival. Most new vessels form at the distal part of the inset (p < 0.01, ANOVA). The total number does not change with time (p = 0.82, ANOVA). New vessels anastomose preferentially with skin. The fall in perfusion after pedicle ligation was significant for all groups except the day 35 group (p = 0.53). CONCLUSIONS Muscle flaps can perfuse after an injury to the anatomical vascular pedicle through neovascularisation at the inset. These new vessels are evident early but may not function adequately to perfuse the flap. Regional variations in neovascularisation suggest that a gradient of ischaemia drives this process. Inset at the cutaneous level is important, which has implications for buried muscle flaps. The correlation between change in flap perfusion after pedicle injury and flap necrosis suggests a role for the former in determining the capacity of a muscle flap to tolerate a pedicle injury and thereby the approach to re-raising it.

Microsurgery 2017; 38:89-93.

Abstract
In free-flap reconstruction of the lower extremity, due either to trauma or pre-existing vascular disease, healthy vessels may not be readily available in the proximity of the defect. A variety of options including a cross-leg free flap, vein grafts, arteriovenous loops, and "bridging" flaps have been used to address the issue. The purpose of this report is to present a case in which a 72-cm long extended bilateral deep inferior epigastric artery perforator (DIEP) free flap was used for coverage of a 20 × 25 cm soft tissue defect of the lower leg following a Gustilo grade IIIC fracture in a 29-year-old man. Because usable recipient vessels were far from the zone of injury, and to avoid complications accompanying long vein grafts, a long flap was necessary. The exposed tibia required coverage with a free flap, but peripheral portions of the defect with exposed muscles could be covered with a skin graft. Thus, a 72 × 12 cm flap was chosen. The flap was based on both bilateral DIEPs and on the superficial circumflex iliac artery (SCIA). The flap survived completely with no complications. After one debulking surgery, the flap and the donor site showed pleasing cosmesis, and the patient could walk without crutches at 18 months after the first surgery. In cases where no healthy recipient vessels can be found close to the defect, we believe that the use of an extended bilateral DIEP flap may be a feasible option which shortens or precludes vein grafts with no additional flap donor sites.

Abstract
BACKGROUND The management of a high voltage electrical injury and lower limb salvage remains a challenging task for plastic surgeons. Reconstruction with flaps is often the only alternative to limb amputation. The purpose of this study was to present a cross flow-through pedicle free latissimus dorsi muscle flap for the salvage of severely traumatized lower limbs perfused by one remaining vessel (a single vessel lower limb) in high voltage electrical injuries. METHODS In this retrospective study, between 2000 and 2014, six men underwent cross-leg free Latissimus dorsi muscle flap operations for limb salvage. They had soft tissue lower leg defects due to high voltage electrical injuries. Their medical records were retrospectively reviewed. All had only one artery that perfused the leg. Free pedicled thoracodorsal artery latissimus dorsi flaps were harvested and connected to the contralateral posterior tibial artery. RESULTS All defects were successfully covered. No flap loss or major amputation occurred during follow-up (mean; 5.9 years). A computerized tomography angiogram showed intact vessel continuity in the recipient vascular system. The patients were able to walk without any apparatus or assistance after long term follow-up. CONCLUSION We recommend that the cross flow-through pedicle free muscle flap should be considered as a salvage procedure for single vessel lower extremities resulting from high voltage electrical burns. Extremity perfusion was not compromised by this procedure.

Abstract
Composite tissue loss in extremities involving neurovascular structures has been a major challenge for reconstructive surgeons. Reconstruction of large defects can only be achieved with microsurgical procedures. The success of free flap operations depends on the presence of healthy recipient vessels. In cases with no suitable donor artery and vein or in which even the use of vein grafts would not be feasible, the lower limb can be salvaged with a cross-leg free flap procedure. We present a case with a large composite tissue loss that was reconstructed with cross-leg free transfer of a combined latissimus dorsi and serratus anterior muscle flap. This case indicates that this large muscle flap can survive with the cross-leg free flap method and this technique may be a viable alternative for large lower extremity defects that have no reliable recipient artery.

Abstract
This article details the experiences of United States military reconstructive surgeons in the soft tissue management of war wounds of the foot and ankle resulting from the conflicts in Iraq and Afghanistan. War wounds from this conflict are commonly caused by blast and fragmentation, and are characteristically extensive, heterogeneous, and severe. Multiple serial débridement episodes are routinely necessary because of deterioration of the wounds over time, which is in contrast to civilian trauma wherein fewer débridement episodes are generally required. Wound therapy adjuncts, such as subatmospheric wound dressing and synthetic dermal replacement, have been used extensively with favorable results. Pedicled flaps, such as the distally based sural neurofasciocutaneous flap, are reliable, and avoid the risks and technical demands associated with microsurgery. Free tissue transfer, such as the anterolateral thigh flap, the latissimus dorsi muscle flap, and the rectus abdominis muscle flap, are powerful reconstructive tools, and have been extensively used in the reconstruction of war wounds of the foot and ankle.

Abstract
BACKGROUND There have been many studies comparing the patency rates of end-to-end and end-to-side microvascular anastomoses in both arteries and veins. Most of them failed to demonstrate a significant difference. The purpose of this study was to compare three different combinations of microvascular anastomoses in a rat vasospasm model, and determine which type of anastomosis is the most tolerant to vasospasm. METHODS Ninety Wistar rats were divided into three groups (n = 30 for each). In each group, a free pectoral skin flap was elevated and microsurgically transferred to the anterior cervical region. In group 1, end-to-end anastomoses were performed on both arteries and veins, in group 2 end-to-side anastomoses were performed on arteries and end-to-end anastomoses were performed on veins, and in group 3 end-to-end anastomoses were performed on arteries and end-to-side anastomoses were performed on veins. After revascularization, vasospasm was induced with topical epinephrine. Flap survival was assessed on day 3, and the success rates of the three groups were compared. RESULTS The flap success rate was 73.3% (22 of 30) in group 1, 66.7% (20 of 30) in group 2, and 96.7% (29 of 30) in group 3. The differences between groups 1 and 3 and between groups 2 and 3 were statistically significant. Overall, venous thrombosis was much more frequent than arterial thrombosis. CONCLUSIONS In a rat epinephrine-induced vasospasm model, venous thrombosis was much more frequent than arterial thrombosis. The type of arterial anastomosis did not affect the success rate, but end-to-side venous anastomosis had a higher success rate than end-to-end venous anastomosis.

Abstract
BACKGROUND Pedicled cross-extremity flaps for lower limb wound coverage have been replaced by free tissue transfer in the last two decades. However, there are certain difficult situations where the free flap cannot be employed and alternative methods are needed. We describe our experience with cross-leg flap in 18 patients for the reconstruction of difficult leg defects in which no suitable recipient vessels were available for microvascular anastomosis in the vicinity of the defect. MATERIALS AND METHODS 18 patients (17 men and 1 woman) with mean range 31.5 yrs(range 18-70 yrs) grade III B tibial fractures were included in the study. fasciocuteneous cross leg flap was employed and extremities were immobilized by external Fixator. RESULTS Fifteen flaps were completely available with two had marginal necrosis and one supsficial epidermal necrosis. No complications were related to the donor site, flap, or by immobilization are noted. Each patient resumed essentially normal gait and activity without any stiffness of joints related with the flap or external fixator. CONCLUSION The addition of external fixator stabilization aids greatly in wound care, as well as for general ease of the patient mobility and positioning. Cross-leg flap offers the possibility of salvaging limbs that are otherwise nonreconstructable.

Abstract
The authors present a case where a cross-leg fillet flap from an amputated limb allowed reconstruction of the contralateral disrupted Achilles tendon and provided neurotized soft tissue. Achilles tendon reconstruction of the left leg was achieved by utilizing vascularized extensor tendons from the dorsum of the right foot based on the dorsalis pedis circulation. Neurotization was accomplished end to side between a cutaneous nerve from the dorsum of the foot and the recipient sural nerve. Healing was complete and without complication. Cross-leg flaps including tendon and nerve may be used to reconstruct complex lower-extremity injuries, even when free flaps are not feasible.

Abstract
This retrospective study was designed to evaluate a salvage technique for free flaps suffering venous congestion by using a cross-leg vein repair in patients with venous-impaired lower extremities. Four free flap reconstructions were performed using the latissimus dorsi muscle to reconstruct soft tissue defects in the lower extremity. The recipient artery was confined to the ipsilateral leg and the venous anastomosis was performed with a long saphenous vein from the contralateral side. The legs were immobilised together by means of an external fixator. All patients were males with a mean age of 31 years. The mean time of pedicle division was 8.8 days (7-10). The mean size of the free flap was 186.5 cm(2). All flaps survived after pedicle division without venous congestion. There were no complications such as joint stiffness or donor site morbidity except for a linear scar. The cross-leg venous repair is a refinement of a salvage procedure for compromised free flaps used in the reconstruction of severe soft tissue defects in vascularly compromised lower extremities.

Abstract
Alternative techniques for pedicle transfer of a reverse radial forearm flap for hand coverage, and a latissimus dorsi myocutaneous free flap for pelvic wound coverage, are illustrated. Exteriorization of the vascular pedicle of a reverse radial forearm flap allows a greater arc of movement of the flap for more distal coverage, and avoids the potential vascular compromise of tunnelling under a tight skin bridge. Two-stage transfer of a latissimus dorsi myocutaneous free flap on a wrist carrier pedicle may be useful in circumstances when local recipient vessels are inadequate for free flap transfer. Although both of these vascular pedicle modifications have drawbacks, they may be of value in limited circumstances. Their advantages and limitations are discussed.

To repair a 10 x 16 cm soft tissue defect of right lower leg that accompanied with occluded anterior and posterior tibial arteries in a 30-year-old man who sustained comminuted type III(B) Gustilo open tibial and fibular fracture, we present a successful reconstruction by using a large distally based sural island flap perfused by the lowermost perforator of the peroneal artery. This flap is a useful alternative for distal extremity reconstruction when anterior and posterior tibial arteries are occluded, as large flaps can be elevated safely based on only one peroneal perforator.

Abstract
The indications for free flaps have been more or less clarified; however, the course of reconstruction after the failure of a free flap remains undetermined. Is it better to insist on one's initial choice, or should surgeons downgrade their reconstructive goals? To establish a preliminary guideline, this study was designed to retrospectively analyze the outcome of failed free-tissue transfers performed in the authors hospital. Over the past 8 years (1990 through 1997), 3361 head and neck and extremity reconstructions were performed by free-tissue transfers, excluding toe transplantations. Among these reconstructions, 1235 flaps (36.7 percent) were transferred to the head and neck region, and 2126 flaps (63.3 percent) to the extremities. A total of 101 failures (3.0 percent total plus the partial failure rate) were encountered. Forty-two failures occurred in the head and neck region, and 59 in the extremities. Evaluation of the cases revealed that one of three following approaches to handling the failure was taken: (1) a second free-tissue transfer; (2) a regional flap transfer; or (3) conservative management with debridement, wound care, and subsequent closure by secondary intention, whether by local flaps or skin grafting. In the head and neck region, 17 second free flaps (40 percent) and 15 regional flaps (36 percent) were transferred to salvage the reconstruction, whereas conservative management was undertaken in the remaining 10 cases (24 percent). In the extremities, 37 failures were treated conservatively (63 percent) in addition to 17 second free flaps (29 percent) and three regional flaps (5 percent) used to salvage the failed reconstruction. Two cases underwent amputation (3 percent). The average time elapsed between the failure and second free-tissue transfer was 12 days (range, 2 to 60 days) in the head and neck region and 18 days (range, 2 to 56 days) in the extremities. In a total of 34 second free-tissue transfers at both localizations, there were only three failures (9 percent). However, in the head and neck region, seven of the regional flaps transferred (47 percent) and four cases that were conservatively treated (40 percent) either failed or developed complications that lengthened the reconstruction period because of additional procedures. Six other free-tissue transfers had to be performed to manage these complicated cases. Conservative management was quite successful in the extremities; most patients' wounds healed, although more than one skin-graft procedure was required in 10 patients (27 percent). In conclusion, a second free-tissue transfer is, in general, a relatively more reliable and more effective procedure for the treatment of flap failure in the head and neck region, as well as failed vascularized bone flaps in the reconstruction of the extremities. Conservative treatment may be a simple and valid alternative to second (free) flaps for soft-tissue coverage in extremities with partial and even total losses.

Abstract
Tensor fascia lata is utilized in the management of complex soft-tissue injuries and defects, but has not been described in the literature in the use of tissue interposition with resection of talocalcaneal middle facet coalitions. This article is a case presentation of a resection of a middle facet coalition with interposition of an allograft of tensor fascia lata. At 14 months postoperative follow-up, range of motion of the subtalar joint was noted to be 20 degrees, and without pain or crepitus. There was no radiographic evidence of degenerative changes in Chopart's joint. The patient returned to all routine and sports activities without pain. He was satisfied with the outcome of the procedure.

Abstract
For the injury of the lower leg associated with both bone and soft-tissue defect, the combined free flap and the Ilizarov distraction method were described as a useful treatment modality. During the procedure of distraction, however, revisions were frequently needed to change the pin position or to change the flap configuration. In case of flap ischemia, distraction should be delayed or abandoned. Then, a vascularized bone transfer might be necessary. To avoid these complications and achieve safe distraction, the configuration of the flap with its vascular pedicle should be carefully planned in terms of the future bony lengthening procedures and the concomitant soft-tissue changes of the lower leg. According to the response of local tissue to the distraction process, the lower limb can be divided into four compartments (active mobile, passive mobile, receptive, and restrictive). The configuration of the transferred free flap with its vascular pedicle can be classified into five types. To minimize the undue forces to the vascular pedicle and reduce the possibility of vascular compromise, the transferred free flap should have the configuration that its vascular pedicle lies in the territory of the mobile compartment. In performing free-tissue transfer combined with the Ilizarov method in the lower extremity, the configuration of the flap with its vascular pedicle should be carefully planned, and the characteristics of lower leg tissue should be kept in mind during the distraction.

Abstract
A 36-year-old woman sustained an amputation of her right leg at the thigh level and a degloving injury of her left foot and ankle region in an accident during a suicide attempt. Primarily, her left foot was covered with a split skin graft, resulting in a soft-tissue defect at the medial malleolus and at the calcaneus bone. Reconstruction was planned with a free latissimus dorsi muscle flap. Preoperative examinations revealed an arteria peronea magna with a hyperplastic peroneal artery solely providing arterial blood supply to the foot. The arteria peronea magna divided into two branches proximal to the upper ankle joint, replacing the dorsal pedis artery and the medial plantar artery. Tibial posterior and tibial anterior arteries were hypoplastic-aplastic. Microvascular end-to-end anastomoses of the flap vessels to the medial branch ("medial plantar artery") of the arteria peronea magna and its concomitant vein at the medial malleolar bone level were successfully performed. The postoperative course was uneventful. Four weeks postoperatively, the patient started walking assisted by a prosthesis on her right thigh stump. This experience demonstrates that even in a case of arteria peronea magna, free flap surgery for lower limb salvage is a reliable and worthwhile method.

Abstract
The proper selection of a recipient vessel is essential for the success of free tissue transfer, especially when the transfer is to the lower extremity. However, a general agreement on which vessel to use has not been reached yet. Conflicting data have been reported on the survival and outcome of the transferred flaps, depending on the vessel used or the location of anastomosis. The aim of this study was to identify the patterns and problems in the selection of recipient vessels for free tissue transfer to the lower extremity and to establish a general guideline for proper selection. From September of 1990 to December of 1997, 50 consecutive, microvascular, free tissue transfers were performed on the lower extremity. The causes requiring soft-tissue coverage included trauma (25), unstable scar (11), chronic osteomyelitis (7), and tumors (7). The mean follow-up period was 22.4 months (range, 2 to 41 months). In 25 cases, the posterior tibial vessel was used as the recipient vessel. The microvascular anastomosis was done proximal to the zone of injury in 45 cases. The two most important factors in the selection of a recipient vessel are the site of injury and the vascular status of the lower extremity. Less important factors include the flap to be used, method, and site of microvascular anastomosis. All the currently feasible options for recipient vessels are included, and the opinions of other surgeons are reviewed. A general guideline is established, and an algorithm for the proper selection of a recipient vessel is proposed. This algorithm is a fast and convenient guide for evaluating the wound and planning the free flap to the lower extremity.

Abstract
From November 1993 to June 1997, long-bone defects in 40 trauma patients were reconstructed with free osteoseptocutaneous fibula flaps. To determine the necessity of routine angiography in traumatized lower limbs before free flap transplantation, a prospective study was carried out. The study subjects were 34 patients, 25 males and 9 females, with an average age of 40.6 years. Reconstruction was performed primarily for bone defects after Gustillo type III b open fractures in 17 patients and secondarily for malunion and osteomyelitis in 17 patients. Reconstructed bone defects included 25 tibias and 9 femurs. Normal pedal pulses were palpable in 31 patients. Angiographic findings were abnormal in seven patients. In the three patients with abnormal pedal pulses, the particular nonpalpable pulses correlated with the vascular lesions shown in the angiograms (one in the tibial anterior artery and two in the tibial posterior artery). Four patients with either injury of the peroneal artery (three cases) or pseudoaneurysm of the tibial anterior artery (one case) had normal pedal pulses. In all patients, microvascular transplantations were performed successfully. Our study demonstrates the importance of thorough clinical evaluation. Preoperative angiography of the injured lower limbs did not provide relevant additional informations in this series. Familiarity with all available techniques makes it possible to cope with almost any difficult posttraumatic vascular condition. Routine recipient-site angiography before microsurgical reconstruction, therefore, seems unjustified.
