Abstract
BACKGROUND Free flap selection in extremity reconstruction can be challenging. The ideal flap has to be thin and pliable to achieve optimal contour and function. We explore the role of the fascia-only anterolateral thigh (fALT) flap in extremity reconstruction. METHODS We conducted a retrospective review of our experience using fALT-free flap for extremity reconstruction over a 2-year period. Patient demographics, mechanism of injury, flap characteristics, complications- and follow-up were recorded. Descriptive statistics were calculated. RESULTS Twelve patients were included. The median (interquartile range [IQR]) age was 34 (28-52) years. One fALT flap was used for upper extremity reconstruction, while 11 flaps were used for lower extremity reconstruction (4 for lower third of the leg, 4 for dorsum of foot, and 3 for heel). The median (IQR) flap surface area was 90 (63-120) cm2 and time from injury to reconstruction was 10 (6-16) days. The postoperative course was uneventful for all flaps except for 1 flap failure and 1 delayed healing. The median (IQR) follow-up was 2 (1-4) months. In all cases, durable soft tissue reconstruction was achieved with no need for revisions. CONCLUSIONS The fALT-free flap can be successfully used in extremity reconstruction. The ALT fascia has robust perfusion that allows for the harvest of a large flap that can be surfaced with a split thickness skin graft. Its thin pliable tissue provides excellent contour for the hand, distal leg, and foot that does not require future thinning, optimizing the cosmetic and functional result.

Abstract
BACKGROUND Microsurgical free tissue transfer may be the only reconstructive option for lower extremity limb salvage. However, the functional and aesthetic results following free tissue transfer after initial salvage may be suboptimal, thus requiring secondary operations to facilitate definitive wound healing and/or refinement. METHODS A multi-institutional retrospective cohort study was performed including patients who underwent lower extremity free tissue transfer from January of 2002 to December of 2020. The authors' primary outcome variable was the presence of secondary surgery after free tissue transfer for lower extremity reconstruction. Independent variables (eg, wound cause, flap, donor type, recipient, comorbidities) were collected. Secondary surgery was categorized as (1) procedures for definitive wound closure and (2) refinement procedures. Multivariable logistic regression was performed to determine which variables were independently associated with the outcome. RESULTS A total of 420 free tissue transfers for lower extremity reconstruction were identified. Secondary surgery was performed in over half (57%) of the patients. Presence of diabetes (OR, 2.0; P = 0.01; 95% CI, 1.2 to 3.5) and use of a latissimus dorsi donor (OR, 2.4; P = 0.037; 95% CI, 1.1 to 5.4) were predictors of wound closure procedures. Fasciocutaneous (OR, 3.6; P < 0.001; 95% CI, 1.8 to 7.2) and myocutaneous (OR, 3.0; P = 0.005; 95% CI, 1.5 to 9.9) flaps were predictors of refinement procedures when compared with muscle-only flaps with skin grafts. CONCLUSIONS The majority of lower extremity free tissue reconstructions required secondary procedures to provide definitive wound closure and/or refinement. Overall, this study provides predictors of secondary surgery that will help formulate patients' expectations of lower extremity limb salvage. CLINICAL QUESTION/LEVEL OF EVIDENCE Risk, III.

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.

Abstract
OBJECTIVES To study the coverage period influence and various parameters concerning the microsurgical act on the patient clinical outcomes. METHODS We report 23 cases of reconstruction of lower limb loss of substance by free flap operated from 2010 to 2021. Among them, 9 patients were operated on as an emergency versus 14 in the secondary or late phase of the trauma. RESULTS The average age of injured patients operated on emergency was 42 years (17-68 years) and 34 years for the patients who undergo deferred surgery (17-57 years). The sex ratio (female/male) was 22% in patients operated on urgently and 7% in patients operated on later. Regarding the type of free flap, it was Serratus anterior muscle flap in 10 cases, Latissismus dorsi flap in 9 cases, ALT flap in 3 cases and Gracilis muscle flap in 1 case. There were 2 failures of vascularized free transfer (8.7%) with complete necrosis of the flap and 3 revision surgeries on venous thrombosis which finally made it possible to obtain 3 flap successes. We analyze the results (complications/osteitis) according to the time to coverage. CONCLUSIONS In our study, we did not find any significant difference between the groups operated in emergency and at a distance concerning the rate of infection and failure of the flaps.

Abstract
BACKGROUND Lower extremity reconstruction of the distal third of the leg is challenging. Free tissue transfer is the criterion standard. The COVID-19 pandemic encouraged seeking alternatives for resource consuming procedures. Bipedicled flaps are flaps with a dual-source subdermal perfusion. The purpose of this study was to assess outcomes of patients who had bipedicled flaps primary or auxiliary local flap for distal third leg/foot reconstruction. METHODS A retrospective review of patients undergoing lower extremity reconstruction (2020-2021) was performed. Inclusion criteria were patients older than 18 years with lower extremity wounds secondary to traumatic injury for which bipedicled flaps were used in the reconstruction. Exclusion criteria included lower extremity wounds secondary to peripheral vascular disease or diabetes. RESULTS Fourteen patients were included in the study. All patients had distal third of the leg/foot wounds, and 12 patients (87.5%) had concurrent leg fractures. In 8 patients (57.1%), the bipedicled flap was used to decrease the wound size and facilitate another concurrent flap: hemisoleus (21.4%), anterior tibialis muscle turnover (14.3%), medial plantar artery (14.3%), and posterior tibial artery perforator (14.3%). Mean wound size for bipedicle flaps used alone was 42.0 ± 18.3 cm2, whereas wounds that required a bipedicled flap with an additional flap were 69.9 ± 80.8 cm2 (P = 0.187). Two patients had partial flap necrosis (14.3%) but healed their defect. One patient had nonunion (7.1%). Limb salvage rate was 100%. CONCLUSIONS Bipedicled flaps can be used as an alternative to free flaps in distal third leg/foot defects in select patients. If distal extremity wounds cannot be covered with a bipedicled flap alone, the flap can be used an accessory flap to facilitate reconstruction with other local flaps.

Abstract
BACKGROUND Soft tissue reconstruction of the thigh defects can usually be achieved with local options. Free tissue transfer may be indicated in very large defects with exposed vital structures and/or a history of radiation therapy where the healing potential of local option is poor. In this study, we evaluated our experience on microsurgical reconstruction of oncological and irradiated thigh defects to assess the risk factors for complications. METHODS Institutional review board-approved retrospective case series study using electronic medical records from 1997 to 2020 was conducted. All patients with irradiated thigh defects derived from oncological resections who underwent microsurgical reconstruction were included. Patient demographics and clinical and surgical characteristics were recorded. RESULTS Twenty free flaps were transferred in 20 patients. Mean age was 60 ± 11.8 years, and median follow-up time was 24.3 months (interquartile range [IQR], 71.4-9.2 months). The most common type of cancer was liposarcoma (n = 5). Neoadjuvant radiation therapy was performed in 60%. Most commonly used free flaps were latissimus dorsi muscle/musculocutaneous flap (n = 7) and anterolateral thigh flap (n = 7) Nine flaps were transferred immediately after resection. Overall, 70% of arterial anastomoses were end-to-end, whereas 30% were end-to-side. Deep femoral artery branches were chosen as the recipient artery in the 45%. Median length of hospital stay was 11 days (IQR, 16.0-8.3 days), and median time to start weight-bearing was 20 days (IQR, 49.0-9.5 days). All were successful except for 1 patient who required additional pedicled flap coverage. The overall major-complication rate was 25% (n = 5, hematoma = 2, venous congestion requiring emergent exploration surgery = 1, wound dehiscence = 1, surgical site infection = 1). Cancer recurred in 3 patients. One required amputation due to cancer recurrence. Age (hazard ratio [HR], 1.14; P = 0.0163), tumor volume (HR, 18.8; P = 0.0006), and resection volume (HR, 2.24; P = 0.0019) were statistically significantly associated with having a major complication. CONCLUSIONS Based on the data, microvascular reconstruction of irradiated post-oncological resection defects shows high flap survival rate and success. Given the large size of flap required, the complex nature and size of these wounds, and history of radiation, wound healing complications are common. Despite this, free flap reconstruction should be considered in irradiated thighs with large defects. Studies with larger cohort and longer follow-up are still required.

Abstract
Aim: The goal of this study was to compare success rates of a regenerative limb salvage approach (rLS) using dehydrated human chorion amnion membrane (dHACM) to traditional flap-based limb salvage (fLS). Materials & methods: This prospective RTC enrolled patients presenting with complex extremity wounds over a 3-year period. Primary outcomes included success of primary reconstruction, persistence of exposed structures, time to definitive closure, and time to weight bearing. Results: Patients meeting inclusion criteria were randomized to fLS (n = 14) or rLS (n = 25). The primary reconstructive method was successful for 85.7% of fLS subjects and 80% of rLS subjects (p = 1.00). Conclusion: This trial provides strong evidence that rLS is an effective option in the setting of complex extremity wounds, with success rates comparable to traditional flaps. Clinical Trial Registration: NCT03521258 (ClinicalTrials.gov).

Abstract
BACKGROUND Advancements in lower extremity (LE) microsurgery have allowed for the expansion of indications for LE reconstructions. This project aims to better understand the temporal pattern and risk factors associated with LE free flap failure based on the clinical indication. MATERIALS AND METHODS We analyzed all patients undergoing LE free flap reconstruction from the American College of Surgeons National Surgical Quality Improvement Program 2012-2019 prospectively collected data to determine rates and timing of reoperation. Free flaps were stratified by indication, type, and timing of reoperation. Weibull survival models were used to compare rates of takebacks among time intervals. Multivariable logistic regression was used to identify independent predictors for unplanned reoperation. RESULTS Four hundred seven of LE free flaps were analyzed. There was a 14.5% rate (59/407) of unplanned reoperation within the first 30 postoperative days (PODs) after surgery. When stratified by the indication necessitating reoperation, patients with an underlying vascular indication had the highest rate of reoperation (40.9%). The reoperation rates were significantly different between indications (P < 0.05) The mean daily proportion of patients experiencing reoperation was highest during POD 0 to 2 (1.47% reoperations per day), which dropped significantly during POD 3 to 10 (0.55% per day) and again during POD 11 to 30 (0.28% per day, P < 0.05). African American race as well as malignant, prosthetic/implant, and wound/infectious indications were significant independent predictors for unplanned reoperation. CONCLUSIONS Lower extremity reconstruction is an important reconstructive option for the coverage of a myriad of defects. Understanding the differences between postoperative reoperation timelines among indication subtypes is important for updated flap monitoring protocols, optimizing ERAS pathways, and beginning dangle protocols.

Abstract
Background: Free tissue transfer is a valuable surgical option for the reconstruction of a myriad of complex lower extremity defects. Currently, there is a paucity of data that examines the risks of complications for each of these unique indications. Methods: Patients undergoing lower extremity free flap reconstruction from the ACS-NSQIP 2011–2019 database were stratified into groups based on the etiology and indication for reconstruction. Rates of major, surgical wound, and medical complications were compared over the first post-operative month. Multivariable logistic regression was used to identify complication predictors. Results: 425 lower extremity free flaps were analyzed. The most common indications for lower extremity free flap reconstruction were wound-related (29%), malignancy (21%), and trauma (17%). Seventeen percent of free flaps had a major post-operative complication, 9% had a surgical wound complication, and 16% had a medical complication. There were no significant differences in major complications between the indications. However, the independent risk factors for major complications varied widely. Those with an indication of malignancy and those who received a musculocutaneous free flap were significantly more likely to have a surgical wound complication compared to the remaining cohort ( p < 0.05). Those requiring free flap reconstruction for orthopedic hardware related concerns as well as those with wound related indications were significantly more likely to have a post-operative medical complication ( p < 0.05). Conclusion: Understanding the unique risk profiles between the various indications and populations of patients undergoing lower extremity free flap reconstruction is critical for providing accurate risk estimations and optimizing post-operative outcomes and monitoring.

Abstract
The anatomy and technique of free muscle flaps - in particular gracilis flap and latissimus dorsi flap - in lower extremity reconstruction have been well described. There is a paucity of data on potential risk factors in larger patient series that affect the outcome. The objective of this study was to address this lack of knowledge by reporting outcomes and complications of free muscle flaps as a primary option in lower extremity reconstruction. From 2009 to 2020, a total of 253 consecutive patients with soft tissue defects of the lower limb from trauma, infection or malignancies underwent lower extremity reconstructive surgery with 266 free muscle flaps. Complications requiring revision surgery were noted in 36.1% of cases. Total flap loss occurred in 10.5% of cases. Patients requiring revision surgery were older, more likely to be female, more likely to be active smokers, and more likely to have a higher ASA score. Lower extremity reconstruction with free muscle flaps has a relevant complication rate that both patient and reconstructive surgeon need to be aware of. Prospective studies should try to further assess the factors affecting the outcome.

Abstract
Composite injuries to the lower extremity from etiologies including trauma and infection present a complex dilemma for the reconstructive surgeon, and require multidisciplinary collaboration amongst plastic, vascular, and orthopaedic surgical specialties. Here we present our algorithm for lower-extremity reconstructive management, refined over the last decades to provide an optimized outcome for our patients. Reconstruction is predicated on the establishment of a clean and living wound, where quality of the wound-bed is prioritized over timing to soft-tissue coverage. Once established, soft-tissues and fractures are provisionally stabilized; our preference for definitive coverage is for microvascular free-tissue, due to the paucity of healthy soft-tissue available at the injury, and ability to avoid the zone of injury for microvascular anastomosis. Finally, definitive bony reconstruction is dictated by the length and location of long-bone defect, with a preference to utilize bone transport for defects longer than 5 cm.

Abstract
BACKGROUND Treatment for large defects in the non-weight-bearing Achilles tendon and soft tissues remains a reconstructive challenge. The free composite anterolateral thigh flap (ALT) with fascia lata (FL) has been indicated in the single-stage reconstruction of the Achilles tendon and soft tissue defect and this technique remain some disadvantages, such as the inability to perform primary flap thinning, requiring secondary flap thinning, and the delayed normalization of the range of motion of the ankle joint. The free chimeric ALT flap with FL was introduced as a novel alternative with many advantages in reconstructing the Achilles tendon and soft tissue defects. This paper reports the reconstruction of the massive Achilles tendon and overlying skin defects using free chimeric ALT flaps with FL. METHODS From June 2017 to October 2020, we performed on a series of 5 patients receiving free chimeric ALT flaps with FL to reconstruct the Achilles tendon and soft tissue defects. The age of patients ranged from 43 to 62 years old. All five patients had full-layer defects of the Achilles tendon with infection. The sizes of the skin defects ranged from 6 × 4 cm to 12 × 10 cm. The perforators from the descending branch of the lateral circumflex femoral arteries are located using a handheld Doppler. The perforators help to design the outline of the ALT flap and fascia flap. The skin flap was thinned under microscopy if the flap was too thick. The anastomosis was accomplished before insetting the flaps into the defect. RESULTS The size of the ALT flap ranged from 10 × 5 cm to 15 × 12 cm, and the size of the FL flap ranged from 7 × 4 cm to 10 × 8 cm. The mean perforator length for the skin flap and fascia lata was 3.3 cm (range, 2.5-5.0 cm) and 5.3 cm (range, 3.5-7.0 cm), respectively. Four patients received skin flap thinning up to 57%-79% of the flap thickness, while one patient did not need to debulk. The thickness of the ALT flap ranged from 6 to 13 mm. All the flaps survived completely and postoperative courses were uneventful without any complications. The follow-up time ranged from 12 to 51 months. All patients were able to stand and ambulate, and they were satisfied with the reconstructive results. CONCLUSIONS The free thin chimeric ALT with FL flap is appeared to be an appropriate treatment for the massive Achilles tendon and overlying skin defects. This may be a practical approach to improve the functional outcomes of patients with infected massive Achilles tendon and overlying skin defects.

Abstract
BACKGROUND Lower extremity salvage in the setting of nonhealing wounds requires a multidisciplinary approach for successful free tissue transfer. Patients with comorbidities including diabetes mellitus and peripheral vascular disease were previously considered poor candidates for free tissue transfer. However, amputation leads to functional decline and severely increased mortality. The authors present their institutional perioperative protocol in the context of 200 free tissue transfers performed for lower extremity salvage in a highly comorbid population. METHODS The authors reviewed an institutional database of 200 lower extremity free tissue transfers performed from 2011 to 2019. Demographics, comorbidities, wound cause and location, intraoperative details, flap outcomes, and complications were compared between the first and second 100 flaps. The authors document the evolution of their institutional protocol for lower extremity free tissue transfers, including standard preoperative hypercoagulability testing, angiography, and venous ultrasound. RESULTS The median Charlson Comorbidity Index was 3, with diabetes mellitus and peripheral vascular disease found in 48 percent and 22 percent of patients, respectively. Thirty-nine percent of patients tested positive for more than three hypercoagulable genetic conditions. The second group of 100 free tissue transfers had a higher proportion of patients with decreased vessel runoff (35 percent versus 47 percent; p < 0.05), rate of endovascular intervention (7.1 percent versus 23 percent; p < 0.05), and rate of venous reflux (19 percent versus 64 percent; p < 0.001). Flap success (91 percent versus 98 percent; p < 0.05) and operative time (500 minutes versus 374 minutes; p < 0.001) improved in the second cohort. CONCLUSIONS Standardized evidence-based protocols and a multidisciplinary approach enable successful limb salvage. Although there is a learning curve, high levels of salvage can be attained in highly comorbid patients with improved institutional knowledge and capabilities.

Abstract
BACKGROUND Complex lower limb reconstruction due to severe trauma remains a challenge for reconstructive surgeons. Here, we introduce a modified donor blood flow-preserved cross-leg anterolateral thigh flap procedure and evaluate its clinical efficacy. METHODS Between January 2013 and December 2019, 22 patients (range 10 to 64 years old) with unilateral lower limb injury underwent modified donor blood flow-preserved cross-leg anterolateral thigh flap procedures. Among them, 16 cases were traffic accidents, 5 cases were persistent ulcers, and 1 case was a degloving injury. The arterial pedicle of the flap was prepared in a Y-shaped fashion and microanastomosed to the posterior tibial artery of intact leg in a flow-through style. A split-thickness skin graft was applied to wrap the vascular pedicle after anastomosis. The flap was designed in a single or bilobed fashion according to the shape of the tissue defect. The operation time, the intraoperative blood loss and the length of hospital stays were recorded. The vascular pedicle was divided 4 weeks after anastomosis. Doppler ultrasound was performed to evaluate the blood flow of the donor posterior tibial artery during postoperative follow-up. RESULTS All 22 flaps survived. The tissue defects ranged from 12 × 6 to 21 × 18 cm2. The flap sizes ranged from 14 × 7.5 to 24 × 21 cm2. The average operation time, intraoperative blood loss and length of hospital stays were 6.73 ± 1.49 h, 280.95 ± 59.25 ml and 30.55 ± 2.52 days, respectively. Eighteen flaps were designed in a single fashion, while four were in bilobed fashion. Twenty patients underwent fasciocutaneous flap transplantations, while two underwent musculocutaneous flap transplantations. Two cases developed local lysis of the flap which healed after further debridement. Direct suture of the incision after flap harvest was performed in 16 cases, while additional full-thickness skin grafting was performed in the remaining 6 cases. Further bone transport procedures were performed in 15 patients who had severe tibia bone defects. The blood flow of donor posterior tibial artery was confirmed in all patients during follow-ups. All patients recovered flap sensation at the final follow-up. The postoperative follow-ups ranged from 18 to 84 months, and no long-term complications were observed. CONCLUSIONS The modified donor blood flow-preserved cross-leg anterolateral thigh flap procedure is an ideal method to repair severe lower limb trauma with tibial artery occlusion which avoids sacrificing the major artery of the uninjured lower limb.

Abstract
OBJECTIVE Opioid-based analgesia is often used in the management of postoperative pain in arthroplasty cases. This article analyses the safety of single-shot peripheral nerve block (PNB) and potential analgesic benefits in patients undergoing lower limb free flap reconstruction. METHODS A retrospective review including all patients undergoing lower limb reconstruction with free flaps between October 2017 and April 2020 was performed. Patients were divided into two groups based on PNB utilization. The use of oral opioids, post-operative pain scores, flap-related outcomes, patient morbidity, and length of hospital stay (LOS) were compared between groups. RESULTS Thirty-one patients who underwent lower limb reconstruction with free flaps, were finally included in the study. Preoperative PNB was performed on 14 patients, while 17 patients received general anesthesia (GA) alone. Pain at rest, measured using the visual analog scale (VAS) score, was significantly lower (2.2 ± 1.7 vs. 4.9 ± 1.7) in the PNB group on postoperative day 1 (POD). The mean [median]±SD amounts of opioids consumed in morphine milligram equivalent (MME) were significantly lower in the PNB group on both POD1 (33.5 [22.5] ± 33.9 vs. 61.6 [48.0] ± 39.0), POD2 (29.0 [15.0] ± 29.2 vs. 58.0 [52.5] ± 37.0) and cumulatively over 7 days (164.0 [197.0] ± 132.8 vs. 315.4 [225] ± 203.2). Complication rates and LOS were not statistically different between groups, although trending toward lower take-back procedures and major complications in the PNB group. CONCLUSION Preoperative single-shot PNB significantly reduced postoperative opioid use and patient-reported pain severity and was not associated with an increase in complication rates.

Abstract
Objective
Advances in reconstructive microsurgery in orthopedic surgery provided better functional and aesthetic results and avoided many indications for amputation. In high-volume trauma and orthopedic hospitals, microsurgical reconstruction is essential to reduce costs and complications for these complex orthopedic defects. We describe a microsurgical approach to traumatic wounds, tumor resection, bone defects, and free muscle transfer, performed by an orthopedic microsurgery unit. The objective of the present study was to evaluate predictor factors for outcomes of microsurgical flaps for limb reconstruction, and to provide a descriptive analysis of microsurgical flaps for orthopedic indications.
Methods
Cross-sectional prospective study that included all consecutive cases of microsurgical flaps for orthopedic indications from 2014 to 2020. Data were collected from personal medical history, intraoperative microsurgical procedure, and laboratory blood tests. Complications and free-flap outcomes were studied in a descriptive and statistical analysis.
Results
We evaluated 171 flaps in 168 patients; the indications were traumatic in 66% of the patients. Type III complications of the Clavien-Dindo Classification were observed in 51 flaps. The overall success rate of the microsurgical flaps was 88.3%. In the multivariate analysis, the risk factors for complications were ischemia time ≥ 2 hours (
p
= 0.032) and obesity (
p
= 0.007). Partial flap loss was more common in patients with thrombocytosis in the preoperative platelet count (
p
= 0.001).
Conclusion
The independent risk factors for complications of microsurgical flaps for limb reconstruction are obesity and flap ischemia time ≥ 2 hours, and presence of thrombocytosis is a risk factor for partial flap loss.

Abstract
INTRODUCTION Soft tissue reconstruction is a routine component of lower extremity trauma care and focus is increasingly being directed towards understanding functional outcomes. This study aims to quantify functional recovery and identify variables associated with functional outcomes of patients who undergo traumatic limb salvage. METHODS A retrospective review was performed of patients with lower extremity traumatic injuries requiring vascularized soft tissue reconstruction at a Level 1 trauma center between July 2007-December 2015. Postoperatively, patients were administered the 36-Item Short Form Health Survey Version 2 (SF-36v2) and the Lower Extremity Functional Scale (LEFS) questionnaires by telephone. Demographics, perioperative variables, and postoperative outcomes were analyzed by univariate and bivariate analysis. RESULTS Forty-two patients with 42 flaps and a mean of 12.7 months follow up were included in the study. Limb salvage was successful in 38 patients (90.5%). Patients ≥ 40 years old had significantly worse SF-36v2 scores in physical functioning (P ≤0.01) and mental health (P ≤0.05) than their younger counterparts. Patients who had pre-existing hypertension demonstrated significantly lower physical functioning (P ≤0.01). Role limitation due to emotional health was significantly lower in patients who were female (P ≤0.01) or required revision surgery (P ≤0.01). The mean LEFS score was 37.7 ± 18.5. CONCLUSIONS Patients exhibited poor functional outcomes following major limb trauma with attempted limb salvage based on two validated patient reported outcomes measures (PROMs). Patient characteristics should be considered in evaluating candidates for reconstruction to optimize outcomes and to effectively counsel patients on their functional prognosis.

Abstract
Background Microvascular free tissue transfer (FTT) is a reliable method for reconstruction of complex soft tissue defects. The goal of this study was to utilize time-driven activity-based cost (TDABC) accounting to measure the total cost of care of FTT and identify modifiable cost drivers.
Methods A retrospective review was performed on patients requiring FTT at a single, level-I academic trauma center from 2013 to 2019. Patient and surgical characteristics were collected, and six prospective FTT cases were observed via TDABC to collect direct and indirect costs of care.
Results When stratified by postoperative stay at intensive care units (ICUs), the average cost of care was $21,840.22, while cases without ICU stay averaged $6,646.61. The most costly category was ICU stay, averaging $8,310.99 (40.9% of nonstratified overall cost). Indirect costs were the second most costly category, averaging $4,388.07 (21.6% of nonstratified overall cost). Overall, 13 of 100 reviewed cases required some form of revision free-flap, increasing cumulative costs to $7,961.34 for cases with non-ICU stay and $22,233.85 for cases with ICU stay, averaging up to $44,074.07 for patients who stayed in the ICU for both procedures. An increase in cumulative cost was also observed within the timeframe of the investigation, with average costs of $8,484.00 in 2013 compared to $45,128 for 2019.
Conclusion Primary drivers for cost in this study were ICU stay and revision/reoperation. Better understanding the cost of FTT allows for cost reduction through the development of new protocols that drive intraoperative efficiency, reduce ICU stays, and optimize outcomes.

Abstract
BACKGROUND The purpose of this study was to compare the reconstructive outcomes of soft-tissue defects around foot and ankle with local or free flaps and attempt to provide an optimal strategy for these patients in comparison with the conventional guidelines. METHODS A retrospective review of all continuous patients with foot and ankle reconstruction using different flaps from 2010 to 2018 was performed. Based on the flap types, the patients were divided into 2 groups: local flap group and free flap group. Outcomes were assessed according to the flap survival rate, recipient complications, aesthetic outcomes, and donor-site complications. RESULT A total of 130 flaps including 47 free flaps and 83 local flaps were collected. There was no difference in flap survival rate between the 2 groups; however, a significant difference in aesthetic outcomes was noted between them: the free flap group presented a better overall aesthetic outcomes in comparison with the local flap group in terms of color and contour match. Moreover, local flaps had more donor-site morbidities including the need for skin grafting and wound infection. CONCLUSIONS Free flaps in wound coverage of foot and ankle can achieve better outcomes than local flaps in terms of recipient benefits and donor-site compromise with a comparable flap survival rate.

Abstract
Summary
Background
Despite continuous surgical advances, reconstruction of complex lower extremity wounds remains challenging. The indication of local flaps or microsurgical free tissue transfer depends on the anatomical location and size of the defect, as well as the comorbidities and general condition of the patient. In this study, local and free flap reconstruction of distal lower extremity defects was assessed, and postoperative complications and limb salvage were analyzed.
Methods
A total of 34 patients were included in this retrospective study. Distal lower extremity defects were of traumatic (29%) and non-traumatic (71%) etiologies. Patient characteristics, flap selection, postoperative complications, and limb preservation within the first 12 months were assessed and compared by reconstructive treatment concept. Statistical analysis included parametric and non-parametric tests. The two-sided alpha was set at 5% for all statistical tests.
Results
While 21 patients were treated with local flaps, 13 patients underwent microsurgical free flap reconstruction. The most common comorbidities were peripheral vascular disease and diabetes. Local flaps included the gastrocnemius muscle flap, soleus flap, sural flap, and plantaris medialis flap. The most commonly used free flaps for soft tissue reconstruction were latissimus dorsi and gracilis muscle flaps. The overall lower extremity preservation rate was 94.1%. There was one case of below-knee amputation 1 month after free flap reconstruction, and one case of first-ray amputation of the foot after local flap coverage.
Conclusion
Reconstruction of lower extremity defects can be achieved by local or free flap reconstruction. Flap selection is influenced by anatomical location, defect size, and patient factors.

Abstract
In order to address complex extremity injuries, the orthoplastic approach uses plastic, orthopedic, and microsurgical techniques and includes other disciplines to optimize limb salvage. This collaboration, if created early in treatment, allows for more expedient and individualized solutions to a variety of extremity injuries resulting in decreased hospital stay, fewer complications, and improved functional outcomes. The orthoplastic approach does not merely avoid amputation, but also improves patient function and quality of life in the short and long term.

Abstract
Free tissue transfer to the lower extremity for limb salvage remains challenging. A comprehensive approach includes patient selection, flap selection, selection of the recipient vessels, flap dissection, flap preparation, microvascular anastomosis, flap inset, immediate postoperative care, intermediate postoperative care, and further follow-up care. Each step in this comprehensive approach has its unique considerations and should be executed equally to ensure an optimal outcome. Once acquired, some clinical experience along with adequate microsurgical skill, good surgical judgment, well instructed and step-by-step intraoperative execution, and a protocol-driven practice, successful free tissue transfer to the lower extremity can be accomplished.

Abstract
BACKGROUND The gracilis muscle free flap has proven to be a dependable tool for the reconstructive microsurgeon for coverage of small- to medium-sized lower-extremity soft tissue defects because of its reliable anatomy, ease of elevation, and minimal donor site morbidity. We describe our experience with the adductor magnus muscle free flap which we have utilized in cases when confronted with the rare situation in which the dominant vascular pedicle to the gracilis muscle is insufficient or absent. METHODS We conducted a retrospective chart review of a single surgeon's experience (EG Melissinos) over an 18-year period of all patients that underwent adductor magnus muscle free flap coverage for lower-extremity soft tissue injuries. RESULTS Twenty-four adductor magnus free flaps in 24 patients were performed over an 18-year period (2000-2018). All of the adductor magnus muscle free flaps were performed with the initial intention of gracilis muscle harvest for lower-extremity soft tissue coverage. The most common wound etiology was motor vehicle collisions (8 patients, 33%). All of the adductor magnus free flaps were used for coverage of lower-extremity wounds in the following anatomic locations: distal third (10 patients, 41.7%), ankle (11 patients, 45.8%) and foot (3 patients, 12.5%). All flaps were successful. There were minimal donor site complications. Limb salvage rate was 100%. CONCLUSIONS Use of the adductor magnus muscle free flap is a reasonable alternative to the gracilis muscle in cases when unfavorable gracilis vascular anatomy is encountered intraoperatively. It can be easily and safely harvested within the same donor incision and permits reliable coverage of small- to medium-sized lower-extremity soft tissue defects while avoiding the morbidity of a secondary donor site.

Abstract
BACKGROUND Arterial revascularization and free flap reconstruction is safe and effective for limb salvage in patients with critical limb-threatening ischemia (CLTI). This study aimed to determine whether reconstruction outcomes were affected by the time interval between endovascular treatment and free flap transfer in lower extremity reconstruction for critical limb ischemia. METHODS Patients who underwent endovascular intervention and subsequent free flap reconstruction with >6 months of follow-up were reviewed. Those with wounds with oncological and traumatic etiologies were excluded. Patients' demographics, risk factors, details of microsurgical procedures, details of endovascular intervention, and flap outcomes were collected. RESULTS Overall, 64 consecutive patients (M:F = 50:14 and mean age, 57.3 [range, 29-82] years) were evaluated between November 2011 and October 2019. Angioplasty failed in three patients. For soft-tissue reconstruction, anterolateral free flaps were used most frequently (n = 54 and 84.4%). Flap-related complications developed in 12 cases, of which five cases included total flap necrosis. The interval between endovascular intervention and free flap transfer was not associated with flap loss in multivariate regression analysis. Patients with kidney transplants and higher serum creatinine were associated with total flap necrosis. Advanced age, failed angioplasty, and perfusion status of the pedal arch were associated with major flap complications. CONCLUSION The time interval between endovascular treatment and free flap reconstruction was not associated with flap complications. Free flap reconstruction of chronic wounds caused by CLTI can be safely planned regardless of the time duration from preoperative angioplasty.

Abstract
In a patient with a high-voltage electrical burns, the extent of burning is greatest at the entrance and exit points of the electric current. As the exit point is usually the ankle and/or foot, these areas may be the most severely damaged. As local tissue is limited in this region, free tissue transfer is usually required for reconstruction. Eleven anterolateral thigh free flaps were placed for the reconstruction of foot and ankle defects caused by electrical burns. When the defects were large, we placed the flaps with two or three perforators. In six patients, recipient vessels were prepared in the trauma region or immediately adjacent thereto. Reconstructions were performed at an average of 23.18 days after the burns, and the average hospitalization time was 42.27 days. Patients with burns on the dorsum of the foot often required toe amputations. In patients who underwent direct reconstruction (without debridement), re-operations were required because of graft loss in other burnt areas. The foot and ankle are the regions most damaged by electrical burns. Vessels in the trauma zone or immediately proximal thereto can serve as recipient vessels. Even when the defect is sizeable, a large anterolateral thigh flap with multiple perforators can be harvested. No vascular problem was encountered during early or late reconstruction. The free flap is very reliable when used to reconstruct foot tissue defects caused by electrical burns.

Abstract
BACKGROUND Even though the benefit of free tissue transfer is uncontested in complex reconstructive cases, vascular compromise and/or flap failure remain a challenge for the surgeon and identification of possible risk factors can aid in the preoperative planning. The aim of this study was to identify the individual risk factors leading to flap failure and/or vascular compromise in free tissue transfers in a single institution over a period of 10 years and to create an index predicting these problems, as well as finding predictors of other postoperative complications. METHODS Data from all the patients undergoing free tissue transfers between 2009 and 2018 were retrospectively analyzed (demographics, comorbidities, flap failure, vascular compromise, and other complications). The results from the univariate and multivariate analyses were used to create an index. RESULTS A predictability index with three classes (low, moderate, and high risk) was calculated for each patient, based on defect etiology and the presence of coronary heart disease, diabetes, smoking, peripheral arterial vascular disease, and arterial hypertension. A patient with moderate-risk index had 9.3 times higher chances of developing vascular compromise than those in the low-risk group, while a high-risk index had 18.6 higher odds (p=0.001). American Society of Anesthesiologists (ASA) classification was found to be a predictor of complications in free tissue transfer (p=0.001). CONCLUSION If patients at a high risk of vascular compromise could be identified preoperatively through this predictability index, patient counseling could be improved and the surgeon might adapt the reconstructive plan and choose an alternative reconstructive strategy.

Abstract
Wounds of the lower extremity involving the distal third of the leg remain a significant challenge due to anatomic location and often poor host physiology. Perforator-based propeller flaps may provide rapid coverage of these wounds with a relatively low rate of major complications and often readily managed minor complications. A thorough vascular evaluation must be performed prior to the procedure to ensure adequate flap design and selection of the correct perforator is performed. They have the added advantage over their soft tissue free flap counterparts in that they have significantly less host morbidity with similar rates of total necrosis.

Abstract
Introduction: Coagulation assessment is often missing in microvascular surgery. We aimed at evaluating the predictive value of thromboelastometry for free flap thrombosis in microvascular surgery patients. Materials and Methods: We enrolled 103 adult patients with traumatic injuries scheduled for microvascular free flap surgery into a prospective observational study. Thirty-six patients with recent trauma underwent surgery within 30 days (ES group), and were compared with 67 trauma patients who underwent surgery later than 30 days (late surgery, LS group) after the injury. Rotational thromboelastometry (RTE) was performed before surgery. Functional fibrinogen to platelet ratio (FPR) ≥ 42 was selected as the main hypercoagulability index. Free flap thrombosis was set as primary outcome. Thrombotic risk factors and duration of surgery related to free flap thrombosis were secondary outcomes. Statistical significance p < 0.05; not significant NS. Results: Six patients (16.7%) in the ES group and 10 (14.9%) in the LS group had free flap thrombosis (NS). In the entire cohort, free flap thrombosis rate increased in the presence of thrombogenic comorbidities (OR 4.059, CI 1.33-12.37; p = 0.014) and prolonged surgery times (OR 1.007, CI 1 - 1.012; p = 0.05). Although hypercoagulability occurred more frequently in the ES group (44.4%) than in the LS group (11.9%; p < 0.001), it was not associated with higher free flap thrombosis rate. In ES group patients with surgery times > 240 min, the risk of free flap thrombosis increased (OR 3.5, CI 1.16-10.6; p = 0.026) with 93.3% sensitivity and 86.7% specificity (AUC 0.85; p = 0.007). In contrast, in LS patients hypercoagulability increased the odds of free flap thrombosis (OR 8.83, CI 1.74-44.76; p = 0.009). Moreover, a positive correlation was found between FPR ≥ 42 and free flap thrombosis rate (r = 0.362; p = 0.003). In the LS group, the presence of thrombogenic comorbidities correlated with free flap thrombosis rate (OR 7, CI 1.591-30.8; p = 0.01). Conclusions: In LS patients with thrombogenic comorbidities, thromboelastometry supports the detection of hypercoagulability and predicts free flap thrombosis risk. In ES patients, postoperative hypercoagulability did not predict free flap thrombosis. Prolonged surgery time should be considered as a risk factor.

Abstract
Objectives. Lower extremity ulcers are quite common in patients with autoimmune diseases. Due to chronic use of immunosuppressants, these wounds may develop into deeper wounds resulting in exposure of bone or tendon, which in turn may require free tissue transfers for coverage. The author reviewed perforator free flap transfers performed in this group of patients and analyzed the results. Methods. A retrospective review was performed on all patients who underwent perforator free flap transfer for coverage of lower extremity ulcers without trauma, over a 10-year period. Patient demographics, administered immunosuppressants, and flap and donor site complications were analyzed. Results. Twenty-two perforator free flap transfers were performed in patients with autoimmune diseases, including 18 thoracodorsal perforator flaps, 2 anterolateral thigh flaps, and 2 deep inferior epigastric artery flaps. There was no total flap loss, but there was a high rate of partial flap necrosis (40.9%) and wound dehiscence (40.9%). Intake of corticosteroids was significantly associated with postoperative complications ( P < .05). Conclusion. As partial loss of flap and wound dehiscence is much more common in this group of patients, treatment may take longer, and a fully informed consent should be obtained preoperatively. Surgeons should not avoid performing perforator free flap transfers in patients with autoimmune diseases under immunosuppression; instead, much more preparation and caution are required.

Abstract
BACKGROUND Free tissue transfer for lower limb reconstruction has become a workhorse procedure for limb-salvage. Compared with other recipient sites, the lower extremity has a higher risk of microvascular complications, in particular with venous anastomosis. The study's objective is to evaluate the evidence, safety, and efficacy of venous coupler use in microsurgical anastomosis in lower limb reconstruction to provide objective appraisal of the surgical techniques. METHODS A systematic review (SR) and meta-analysis (MA) were performed analyzing articles from PubMed, Cochrane, Embase, and Web of Science from January 1990, to August 2018. Abstracts and titles were screened and assessed for eligibility by independent reviewers. Following full-text review, articles were included in the SR and MA. Case reports were excluded. Cochrane Collaboration and the Quality of Reporting of Meta-analyses (QUOROM) guidelines were followed. RESULTS Out of 15 included studies that met the inclusion criteria for the SR, 9 were included in MA. Patients treated with venous couplers did not experience more surgical complications (risk ratio (RR) 0.79; 95% confidence interval (CI) 0.48-1.33; p = .38), total failure (RR 0.61; 95% CI 0.22-1.70; p = .34), venous compromise (RR 0.72; 95% CI 0.23-2.27; p = .57), arterial compromise (RR 0.85; 95% CI 0.25-2.88; p = .80), partial failure (RR 0.77; 95% CI 0.33-1.77; p = .54), or reoperation (RR 11.79; 95% CI 0.49-286.55; p = .13) in comparison with hand-sewn anastomosis. CONCLUSIONS Outcomes of venous couplers in lower limb reconstruction are comparable to those of hand-sewn anastomosis. However, this study was limited by the quality of the available literature. Additional prospective studies should aim to directly compare both techniques and potential further benefits in clinical trials.

Abstract
Objective Free flap surgeries constitute the basis of reconstruction surgery in patients with major defects. Prediction of complications that cause flap loss in such patients is important in terms of reducing the length of hospital stay and expenses. We aimed to retrospectively investigate the effect of co-morbidities and the coagulation status on flap loss and complications in patients with reconstructed free flap. Methods Demographic data, smoking, alcohol habits, co-morbidities, coagulation tests and thromboelastogram results from preoperative, intraoperative and postoperative anaesthesia and surgical records of patients undergoing free flap surgeries between January 2015 and June 2017 were retrospectively screened. Results Flap success rate was found to be 96.1% in total 77 patients with free flap. Coagulation related complication rate, such as thrombosis, haematoma and partial necrosis, were 22.1%. There was a significant relationship between age, chronic obstructive pulmonary disease and hypercholesterolaemia and flap loss (p=0.006, p=0.025 ve p=0.025, respectively). Flap complications were more frequent in patients with chronic obstructive pulmonary disease and hypertension. Laboratory test results revealed no statistical correlation between flap complications and flap loss with preoperative and postoperative TEG. Conclusion Advanced age, co-morbidities such as hypertension and chronic obstructive pulmonary disease are associated with complications and flap loss in free flap surgery. However, there were no clinically significant association of complications and flap loss with laboratory tests showing coagulation. We believe that standardised protocols should be established in terms of preparation, intraoperative management and postoperative follow-ups because the time between taking the coagulation tests and postoperative anticoagulant administration should be standardised in such surgeries.

Abstract
Performing a greater number of free flap procedures inevitably results in an increase in the number of cases that experience free flap failure. In cases that require a second free flap after the failure of the first, recipient vessel selection becomes difficult. Furthermore, recipient vessel selection can be complicated if the vessel is deep in the recipient site, or if there is an increased risk of vessel damage during the dissection. Thus, we present our experience where a subfascial vessel beneath the deep fascia was used as a recipient vessel for a second free flap in lower extremity reconstruction due to total or partial first flap failure.Between January 2010 and April 2015, 5 patients underwent second free flap reconstruction using a subfascial vessel as the recipient vessel. The flaps were anastomosed in a perforator-to-perforator manner, using the supermicrosurgery technique. We measured the sizes of the flaps, which varied from 5 × 3 to 15 × 8 cm, and the recipient subfascial vessel diameters.The mean time for the dissection of the recipient perforator was 45 minutes. All the flaps exhibited full survival, although a partial loss of the skin graft at the flap donor site was observed in 1 patient; this defect healed with conservative management.We recommend using a subfascial vessel as the recipient vessel for both first and second free flaps, especially if access to the major vessel is risky or challenging.

Abstract
BACKGROUND Clinical indications are expanding for the use of fasciocutaneous free flaps in lower extremity traumatic reconstruction. The authors assessed the impact of muscle versus fasciocutaneous free flap coverage on reconstructive and functional outcomes. METHODS A multicenter retrospective review was conducted on all lower extremity traumatic free flaps performed at Duke University (1997 to 2013) and the University of Pennsylvania (2002 to 2013). Muscle and fasciocutaneous flaps were compared in two subgroups (acute trauma and chronic traumatic sequelae), according to limb salvage, ambulation time, and flap outcomes. RESULTS A total of 518 lower extremity free flaps were performed for acute traumatic injuries (n = 238) or chronic traumatic sequelae (n = 280). Muscle (n = 307) and fasciocutaneous (n = 211) flaps achieved similar cumulative limb salvage rates in acute trauma (90 percent versus 94 percent; p = 0.56) and chronic trauma subgroups (90 percent versus 88 percent; p = 0.51). Additionally, flap choice did not impact functional recovery (p = 0.83 for acute trauma; p = 0.49 for chronic trauma). Flap groups did not differ in the rates of flap thrombosis, flap salvage, flap loss, or tibial nonunion requiring bone grafting. Fasciocutaneous flaps were more commonly reelevated for subsequent orthopedic procedures (p < 0.01) and required fewer secondary skin-grafting procedures (p = 0.01). Reconstructive and functional outcomes remained heavily influenced by injury severity. CONCLUSIONS Muscle and fasciocutaneous free flaps achieved comparable rates of limb salvage and functional recovery. Flap selection should be guided by defect characteristics and reconstructive needs. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.

Abstract
Background: The purpose of this study was to introduce a comprehensive approach to lower extremity free-tissue transfer and report the clinical outcome that has been achieved with this approach. Methods: The comprehensive approach developed by the author includes patient selection, flap selection, selection of the recipient vessels, flap dissection, flap preparation, microvascular anastomosis, flap inset, immediate postoperative care, intermediate postoperative care, and further follow-up care. Each part of this approach has its own special considerations. In an 8-year period, 28 consecutive lower extremity free-tissue transfers were performed in 28 patients by the author. The clinical outcomes were recorded based on the success of free-tissue transfer, any reoperations related to the revision of microvascular anastomosis, and any partial or total flap loss during an 8-year follow-up. Results: All 28 lower extremity free-tissue transfers were performed successfully. All patients were discharged home once they tolerated dangling. No reoperations were needed for revision of microvascular anastomosis. No total or partial flap loss was encountered. Overall success of free-tissue transfer to the lower extremity in this series was 100%. Conclusions: An ideal outcome of free-tissue transfer to the lower extremity can be accomplished with this comprehensive approach developed by the author. With good surgical judgment, adequate microsurgical skill, step-by-step intraoperative execution, and a protocol-driven clinical practice, the reconstructive surgeon should be able to improve his or her success for free-tissue transfer to the lower extremity.

Abstract
BACKGROUND Reconstruction of the popliteal fossa using a free flap is challenging. Therefore, to facilitate easier free flap reconstruction of the popliteal fossa, we use a medial sural artery perforator (MSAP) free flap with a medial sural vessel as the recipient vessel, as it provides several advantages based on many reports. METHODS This report describes the authors' experience and outcomes with this technique. Between October 2010 and January 2015, 10 patients with medium-sized defects in their popliteal fossa underwent MSAP free flap reconstruction using the medial sural vessel as the recipient vessel. The flap size and thickness were evaluated, as well as the pedicle length, for each case. RESULTS The skin flap sizes ranged from 60-112 cm2. The average flap thickness was 6 mm (range = 4-8 mm), and the average pedicle length was 7.5 cm (range = 6-9 cm). Full flap survival was observed in nine cases, and flap tip necrosis was observed in one case during a mean follow-up of 15 months (range = 3-36 months). MSAP free flap reconstruction was performed for moderate-sized defects in the popliteal fossa, using the medial sural vessel as the recipient vessel. CONCLUSION The obvious advantages of this technique included simple vascular anastomosis (minimal size discrepancy), no intraoperative position changes, and good aesthetic outcomes (replacing like with like).

Abstract
Background There have been significant advancements in lower extremity reconstruction over the last several decades, and the plastic surgeon's armamentarium has grown to include free muscle and fasciocutaneous flaps along with local perforator and propeller flaps. While we have found a use for a variety of techniques for lower extremity reconstruction, the free gracilis has been our workhorse flap due to the ease of harvest, reliability, and low donor site morbidity. Methods This is a retrospective review of a single surgeon's series of free gracilis flaps utilized for lower extremity reconstruction. Demographic information, comorbidities, outcomes, and secondary procedures were analyzed. Results We identified 24 free gracilis flaps. The duration from injury to free flap coverage was ≤ 7 days in 6 patients, 8-30 days in 11 patients, 31-90 days in 4 patients, and > 90 days in 3 patients. There were 22 (92%) successful flaps and an overall limb salvage rate of 92%. There was one partial flap loss. Two flaps underwent incision and drainage in the operating room for infection. Two patients developed donor site hematomas. Four patients underwent secondary procedures for contouring. Our subset of pediatric patients had 100% flap survival and no secondary procedures at a mean 30-month follow-up. Conclusion This study demonstrates the utility of the free gracilis flap in reconstruction of small- to medium-sized defects of the lower extremity. This flap has a high success rate and a low donor site morbidity. Atrophy of the denervated muscle over time allows for good shoe fit, often obviating the need for secondary contouring procedures.

Abstract
BACKGROUND Currently, increased interest in the perforator-pedicled propeller flap should not obscure the fact that it is, in reality, a complex procedure requiring experience and monitoring similar to free flaps. Through a meta-analysis, the authors aimed to identify the risk factors of perforator-pedicled propeller flap failure in lower extremity defects. METHODS The MEDLINE, PubMed Central, Embase, and Cochrane databases were searched from 1991 to May of 2014 for articles describing perforator-pedicled propeller flaps in the lower extremity. The study selection met the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Fixed-effects models were used. RESULTS Forty articles complied with the inclusion criteria, representing 428 perforator-pedicled propeller flaps. The most common cause was posttraumatic (55.2 percent). Most of the defects were at the distal third of the lower leg (45.6 percent). The arc of rotation was 180 degrees for 34.3 percent. Complications were found in 25.2 percent, including partial necrosis (10.2 percent) and complete necrosis (3.5 percent). Complete flap survival was found in 84.3 percent. The authors identified three significant risk factors: age older than 60 years (relative risk, 1.61; p = 0.03), diabetes (relative risk, 2.00; p = 0.02), and arteriopathy (relative risk, 3.12; p = 0.01). No significant results were found regarding smoking status other than a tendency (p = 0.06), acute cause (p = 0.59), posttraumatic cause (p = 0.97), distal third of the lower leg (p = 0.66), fascia inclusion (p = 0.70), and pedicle rotation greater than 120 degrees (p = 0.41). CONCLUSION Age older than 60 years, diabetes, and arteriopathy are significant risk factors of perforator-pedicled propeller flap complications in the lower extremity. CLINICAL QUESTION/LEVEL OF EVIDENCE Risk, IV.

Abstract
INTRODUCTION Currently, increasingly reconstructive surgeon consider the failure rates of perforator propeller flaps especially in the distal third of the lower leg are too important and prefer to return to the use of free flap at first line option with failure rates frequently lower than 5%. So, we performed a systematic review with meta-analysis comparing free flaps (perforator-based or not) and pedicled-propeller flaps to respond to the question "what is the safest coverage for distal third of the lower limb?" METHODS This review was conducted according to PRISMA criteria. From 1991 to 2015, MEDLINE®, Pubmed central, Embase and Cochrane Library were searched. The pooled estimations were performed by meta-analysis. The homogeneity Q statistic and the I2 index were computed. RESULTS We included 36 articles for free flaps (1,226 flaps) and 19 articles for pedicled-propeller flaps (302 flaps). The overall failure rate was 3.9% [95%CI:2.6-5.3] for free flaps and 2.77% [95%CI:0.0-5.6] for pedicled-propeller flaps (P = 0.36). The complication rates were 19.0% for free flaps and 21.4% for pedicled-propeller flaps (P = 0.37). In more detail, we noted for free flaps versus pedicled-propeller flaps: partial necrosis (2.70 vs. 6.88%, P = 0.001%), wound dehiscence (2.38 vs. 0.26%, P = 0.018), infection (4.45 vs. 1.22%, P = 0.009). The coverage failure rate was 5.24% [95%CI:3.68-6.81] versus 2.99% [95%CI:0.38-5.60] without significant difference (P = 0.016). CONCLUSION In the lower limb the complications are not rare and many teams consider the free flaps to be safer. In this meta-analysis we provide evidence that failure and overall complications rate of perforator propeller flaps are comparable with free flaps. Although, partial necrosis is significantly higher for pedicled-propeller flaps than free flaps, in reality the success of coverage appears similar. © 2016 Wiley Periodicals, Inc.

Abstract
BACKGROUND Limb elevation is a commonly used approach for reducing edema and increasing venous drainage. Considering the anatomy of the sural flap with retrograde perfusion and hence potentially difficult blood outflow, the best angle for positioning the leg following operation is not yet known. METHODS A total of 14 patients undergoing sural flap lower limb reconstruction were enrolled in the study. We assessed the perfusion dynamics of the flaps using the oxygen-to-see (O2C) device that combines laser light, to determine blood flow, and white light to determine the relative amount of hemoglobin and oxygen saturation. Three different positions were evaluated: 45° angle downward, the horizontal position, and 45° angle upward. RESULTS The blood flow was significantly higher in the 45° upward position compared to the 45° downward position. The relative amount of hemoglobin was significantly lower in the 45° upward position compared to the 45° downward position. No significant differences with regard to oxygen saturation were observed. CONCLUSION The results of this study show a more precise pattern of perfusion due to different positioning. The 45° upward position of the leg generally maintains the best blood flow and venous drainage. However, compared to horizontal positioning, these differences were not statistically significant. As an elevation of 45° can be uncomfortable for patients, we recommend an elevation of the leg which approximates the 45° upward position but is still comfortable.
