Abstract
BACKGROUND Perforator flaps have revolutionized lower limb reconstruction by offering single-stage thin, pliable coverage with an excellent aesthetic match. Although anastomosis of the flap to a major artery remains the gold standard, perforator-to-perforator anastomosis has several advantages, including expedient recipient dissection and increased recipient options in vessel-depleted extremities. The aim of this study was to compare flap survival when a perforator or major artery was used as a recipient vessel. METHODS A retrospective cohort of free perforator flaps for lower limb reconstruction was reviewed. Demographics, comorbidities, vascular status, defect characteristics, operative details, and complications were recorded. Outcomes for perforator and major artery recipients were compared. RESULTS Four hundred twenty-three flaps were performed for various reasons using perforator flaps. The total limb salvage rate was 98.8 percent. Total and partial flap failure rates were 6.1 percent and 9.0 percent, respectively. Comparing perforator recipients [n = 109 (25.8 percent)] to major artery recipients [n = 314 (74.2 percent)], there was no significant difference in total (p = 0.746) or partial flap failure (p = 0.212). Significant factors between the groups included larger flap size with major artery recipients (p = 0.001) and shorter operative time when using a perforator recipient (p = 0.012). CONCLUSIONS Perforator-to-perforator anastomosis is a reliable option that affords equivalent rates of flap success compared to major artery anastomosis in lower extremity reconstruction. The authors advocate using a major artery recipient in defects where the axial vessels are easily accessible. A perforator recipient is a viable alternative in defects where access to the axial vessels is inconvenient and in patients with limited recipient options.

Abstract
BACKGROUND Human adipose-derived stem cells (hASCs) play an important role in regenerative medicine. OBJECTIVE Exploring the mechanism of Rg1 in the promotion of the proliferation and adipogenic differentiation of hASCs is important in regenerative medicine research. METHODS To observe ginsenoside Rg1 in promoting the proliferation and adipogenic differentiation of hASCs, Rg1 medium at different concentrations was established and tested using the cell counting kit-8 (CCK-8) assay, oil red O staining, alizarin red, and alcian blue. Compared to the control, differentially expressed genes (DEGs) were screened via DEG analysis, which was carried out in the Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses. To explore the relationship among mRNA, long non-coding RNA (lncRNA) and microRNA (miRNA), we constructed a competing endogenous RNA (ceRNA) network. RESULTS In this study, Rg1 was observed to promote the proliferation and adipogenic differentiation of hASCs. Additionally, enriched BPs and KEGG pathways may be involved in the promotion process, where FXR1 and Lnc-GAS5-AS1 were found to be regulatory factors. The regulatory network suggested that Rg1 could regulate the adipocytokine signaling pathway and IL-17 signaling pathway via FXR1 and Lnc-GAS5-AS1, which served as the mechanism encompassing the promotion of Rg1 on the proliferation and adipogenic differentiation of hASCs. CONCLUSION A comprehensive transcriptional regulatory network related to the promotion ability of Rg1 was constructed, revealing mechanisms regarding Rg1's promotion of the proliferation and adipogenic differentiation of hASCs. The present study provides a theoretical basis for optimizing the function of hASCs.

Soft-tissue reconstruction in lower-leg fracture-related infections: An orthoplastic outcome and risk factor analysis. Injury 2021; 52:3489-3497. [PMID: 34304885 DOI: 10.1016/j.injury.2021.07.022] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/25/2021] [Revised: 07/02/2021] [Accepted: 07/13/2021] [Indexed: 02/02/2023]
Abstract
Introduction Fracture-related infection (FRI) is a severe post-traumatic complication which is occasionally accompanied by a deficient or even avital soft-tissue envelope. In these cases, a thoroughly planned orthoplastic approach is imperative as a vital and intact soft-tissue envelope is mandatory to achieve fracture union and infection eradication. The aim of this study was, to analyse if soft-tissue reconstruction (STR) without complications is associated with a better long-term outcome compared to FRI patients with STR complications. In particular, it was investigated if primary flap failure represented a risk factor for compromised fracture union and recurrence of infection. Patients and Methods Patients with a lower leg FRI requiring STR (local, pedicled and free flaps) who were treated from 2010-18 at the University Hospital Basel were included in this retrospective analysis. The main outcome measure was the success rate of STR, further outcome measures were fracture nonunion and recurrence of infection. Results Overall, 145 patients with lower leg FRI were identified, of whom 58 (40%) received STR (muscle flaps: n = 38, fascio-cutaneous flaps: n=19; composite osteo-cutaneous flap: n = 1). In total seven patients required secondary STR due to primary flap failure. All failures and flap-related complications occurred within the first three weeks after surgery. Secondary STR was successful in all cases. A high Charlson Comorbidity Index Score was a significant risk factor for flap failure (p = 0.011). Out of the 43 patients who completed the 9-month follow-up, 11 patients presented with fracture nonunion and 12 patients with a recurrent infection. Polymicrobial infection was a significant risk factor for fracture nonunion (p = 0.002). Primary flap failure was neither a risk factor for compromised fracture consolidation (p = 0.590) nor for recurrence of infection (p = 0.508). Conclusion: A considerable number of patients with lower-leg FRI required STR. This patient subgroup is complex and rich in complications and the long-term composite outcome demonstrated a high rate of compromised fracture consolidation and recurrent infections. It appears that secondary STR should be performed, as primary flap failure was neither a risk factor for compromised fracture consolidation nor for recurrence of infection. We propose to monitor these patients closely for three weeks after STR.

Abstract
BACKGROUND Distal lower extremity reconstruction can be challenging in terms of flap design. Bulky flaps result in limited mobility accompanied with the need of customized footwear. Raising the ALT-flap in a superficial fascial plane (thin ALT-flap) can be beneficial. This study evaluates thin ALT-flaps for lower distal extremity reconstruction. METHODS In a retrospective study, patients that underwent microvascular extremity reconstruction at the level of the ankle and dorsal foot at the University of Freiburg from 2008-2018 were reviewed. RESULTS 95 patients could be included in the study (35 perforator flaps, 8 fascia flaps and 54 muscle flaps).Among the perforator flaps, 21 ALT-flaps were elevated conventionally and 14 in the superficial fascial plane (thin ALT-flap). Among the conventional ALT-flaps, there was one flap loss (5%) and one successful revision (5%). 5(24%) flaps received secondary thinning. 57%(n = 12) were able to wear conventional footwear. There were 2(15%) successful revisions of thin ALT-flaps. 100% of thin ALT-flaps survived and 85%(n = 11) of the patients wore ordinary footwear after defect coverage.Among fascial flaps, 50%(n = 4) had to be revised with 2(25%) complete and 1 (13%) partial flap loss. All patients achieved mobility in ordinary shoes (n = 8).In muscle flaps, there were 7(13%) revisions and 5(9%) flap losses. 5(9%) flaps received secondary thinning. Only 33%(n = 18) were mobile in ordinary footwear. CONCLUSION The thin ALT-flap is a save one-stage evolution for lower distal extremity reconstruction with a favorable flap survival rate. Compared with conventional ALT-flaps it might be beneficial in reducing the need for expensive custom fitted shoes and secondary thinning procedures.

Abstract
OBJECTIVES To evaluate the outcomes of patients who underwent soft tissue flap coverage during treatment of a tibia fracture nonunion. DESIGN Retrospective analysis on prospectively collected data. SETTING Academic medical center. PATIENTS/PARTICIPANTS One hundred fifty-seven patients were treated for a fracture nonunion after a tibia fracture over a 15-year period. Sixty-six patients had sustained an open tibial fracture initially and 25 of these patients underwent soft tissue flaps for their open tibia fracture nonunion. INTERVENTION Manipulation of soft tissue flaps, either placement or elevation for graft placement in ununited previously open tibial fractures. MAIN OUTCOME MEASUREMENTS Bony healing, time to union, ultimate soft tissue status, postoperative complications, and functional outcome scores using the Short Musculoskeletal Functional Assessment (SMFA). This group was compared with a group of open tibial fracture nonunions that did not undergo soft tissue transfer. RESULTS Bony healing was achieved in 24 of 25 patients (96.0%) who received flaps at a mean time to union of 8.7 ± 3.3 months compared with 39 of 41 patients (95.1%) at a mean 7.5 ± 3.2 months (P > 0.05) in the noncoverage group. Healing rate and time to union did not differ between groups. At latest follow-up, the flap coverage group reported a mean SMFA index of 17.1 compared with an SMFA index of 27.7 for the noncoverage group (P = 0.037). CONCLUSIONS Utilization of soft tissue flaps in the setting of open tibia shaft nonunion repair surgery are associated with a high union rate (>90%). Coverage with or manipulation of soft tissue flaps did not result in improved bony healing rate or time to union compared with those who did not require flaps. However, soft tissue flap coverage was associated with higher functional scores at long-term follow-up. LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
The complex lower extremity wound is frequently encountered by orthopedic and plastic surgeons. Innovations in wound care, soft tissue coverage and surgical fixation techniques allow for improved functional outcomes in this patient population with highly morbid injuries. In this review, the principles of reconstruction of complex lower extremity traumatic wounds are outlined. These principles include appropriate initial evaluation of the patient and mangled extremity, as well as appropriate patient selection for limb salvage. The authors emphasize proper planning for reconstruction, timing of reconstruction and the importance of an understanding of the most appropriate reconstructive option. The role of different reconstructive and wound care modalities is discussed, notably negative pressure wound therapy and dermal substitutes. The role of pedicled flaps and microvascular free-tissue transfer are discussed, as are innovations in understanding of perforator anatomy and perforator flap surgery that have broadened the reconstruction surgeon’s armamentarium. Finally, the importance of a multidisciplinary team is highlighted via the principle of the orthoplastic approach to management of complex lower extremity wounds. Upon completion of this review, the reader should have a thorough understanding of the principles of contemporary lower extremity reconstruction.

Abstract
Microsurgical free flap reconstruction in acute burn care offers the option of reconstructing even challenging defects in a single stage procedure. Due to altered rheological and hemodynamic conditions in severely burned patients, it bears the risk of a higher complication rate compared to microsurgical reconstruction in other patients. To avoid failure, appropriate indications for free flap reconstruction should be reviewed thoroughly. Several aspects concerning timing of the procedure, individual flap choice, selection and preparation of the recipient vessels, and perioperative measures must be considered. Respecting these specific conditions, a low complication rate, comparable to those seen in microsurgical reconstruction of other traumatic limb defects, can be observed. Hence, the free flap procedure in acute burn care is a relatively safe and reliable tool in the armamentarium of acute burn surgery. In reconstructive burn care, microsurgical tissue transfer is routinely used to treat scar contractures. Due to the more robust perioperative condition of patients, even lower rates of complication are seen in microsurgical reconstruction.

Abstract
Over the past two decades, management of open distal tibial fractures has evolved such that a staged approach, with external fixation and débridement during the index procedure, followed by definitive fixation and wound closure at a later date, is often considered the standard of care. Although definitive treatment of these complex injuries is often done by a multidisciplinary team of surgeons well versed in periarticular fracture repair and soft-tissue coverage in the distal extremity, the on-call orthopaedic surgeon doing the index procedure must understand the principles and rationale of the staged treatment algorithm to avoid compromising definitive treatment options and ensure the best possible patient outcome. The mechanism of injury, neurovascular status, size and location of soft-tissue injury, fracture pattern, and concomitant injuries in the polytraumatized patient should direct the treatment plan and anticipated outcomes. This review focuses on evaluation and management of these complex injuries with an emphasis on early aggressive débridement, principles of initial fracture fixation, and modern options for soft-tissue coverage, including local and free tissue transfer.

Abstract
INTRODUCTION Coverage of circumferential wounds on limbs is a challenging reconstructive job. Here, we propose a skin flap-based algorithm to reconstruct circumferential wound with the chain-linked design and combined transplantation of ALTP and DIEP flap, which could achieve full-coverage and simultaneously primary donor-site closure. PATIENT AND METHODS From December 2007 to December 2018, 14 patients with circumferential would on upper or lower limbs underwent reconstruction with ALTP or DIEP flap, by the technique of combined transplantation or chain-linked design, or both. The wound was classified into five different types according to the width compared to the donor site (overall magnitudes and regularity), which was separately reconstructed by five different wound decomposition and corresponding flap design. Flap survivorship, complication on recipient or donor site and any secondary surgeries have been recorded. RESULTS 14 patients were successfully treated with 22 flaps, including seven patients reconstructed with one flap (4 bi-pedicled, 2 tri-pedicled), 6 patients reconstructed with two flaps (1 in mono-pedicled, 5 in multi-pedicled), one with 3 flaps and skin grafts. Only one donor site was not directly closed, and one experienced dehiscence but finally healed. All flaps survived uneventfully but three had minor edge necrosis and later treated with skin graft. CONCLUSION The algorithm is practical in circumferential wound resurfacing on limbs for allowing flexible design, sufficient coverage, and low donor site morbidity.

Abstract
BACKGROUND The free anterior branch split latissimus dorsi flap has a reliable anatomy and advantages over the traditional latissimus dorsi flap. By preserving the posterior branch of the thoracodorsal nerve, morbidity at the donor site is reduced, preserving shoulder strength. METHODOLOGY The purpose of this article is to review our experience with the split latissimus flap, describe our surgical technique, and finally review representative cases of reconstruction in different anatomical regions. RESULTS From April 2017 to October 2020, 39 free split latissimus flaps were performed at a single center. Flaps were performed for coverage in the upper extremity (n = 2), lower extremity (n = 32), and head and neck (n = 5). Flap success rate was 97.4%. Mean dimensions of the flap were 17.0 × 8.3 cm, with a mean area of 145 cm2. CONCLUSIONS The flap has a broad application and can be utilized in many different reconstructive scenarios including for coverage of defects in the extremities, trunk, and head and neck.

Abstract
BACKGROUND Function and cosmesis are crucial in upper extremity reconstruction. Yet, there persists a lack of outcome evaluations, particularly regarding differences between free flap types. METHODS In a single-center retrospective analysis, outcomes were compared between patients with cutaneous or muscle free flaps for distal upper extremity reconstruction between 2008 and 2018. The Disabilities of Arm, Shoulder and Hand -Score, Michigan-Hand (MHQ), and Short Form 36 Health Survey (SF-36) Questionnaires were assessed, motor function was quantified, and self-reported measures of cosmesis were compared, including the Vancouver Scar-Scale (VSS), MHQ aesthetics-subscale (MAS), and Moscona's cosmetic validation-score (CVS). RESULTS One-hundred forty-one cases were identified, with a shift toward cutaneous flaps over the study period. Muscle flaps were used for larger defects (251 vs. 142 cm2, p = 0.008). Losses, thromboses, and donor-site complications were equally distributed. Partial necroses were more frequent in muscle flaps (11 vs. 1%, p = 0.015). Seventy patients with 53 cutaneous versus 17 muscle flaps were reexamined. There was no difference in the timing of flap coverage (after 16 vs. 15 days, p = 0.79), number of preceding (2 vs. 1.7, p = 0.95), or subsequent operations (19/53 vs. 5/17, p = 0.77). Patients with cutaneous flaps showed higher grip strength (25 vs. 17 kg, p = 0.046) and reported better hand function (MHQ: 58 vs. 47, p = 0.044) and general health (SF-36: 70 vs. 61, p = 0.040), as well as more favorable appearance (MAS: 71 vs. 57, p = 0.044, CVS: 77 vs. 72, p = 0.048), and scar burden (VSS: 0 vs. 3, p < 0.001). CONCLUSION Cutaneous flaps yielded better motor function, self-perceived cosmesis, patient satisfaction, and quality of life in our cohort of distal upper extremity reconstructions.

Free Medial Plantar Flap Versus Free Dorsal Myocutaneous Flap for the Reconstruction of Traumatic Foot Sole Defects. Ann Plast Surg 2021; 84:S178-S185. [PMID: 32294068 DOI: 10.1097/sap.0000000000002373] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/27/2022]
Abstract
BACKGROUND Trauma can cause large defects in the weight-bearing foot sole. The reconstruction of such defects poses a major challenge in providing a flap that is durable, sensate, and stable. The pedicled medial plantar flap has been commonly used for reconstructing heel and plantar forefoot defects; however, the ipsilateral instep region is usually compromised by trauma. The purpose of this article was to report the use of contralateral free medial plantar flaps for the coverage of weight-bearing plantar defects and to compare these with distant free flaps. METHODS Between 2005 and 2019, 15 patients (10 men and 5 women) with weight-bearing foot plantar defects were treated with a contralateral medial plantar flap, 11 (7 men and 4 women) with either a latissimus dorsi flap or a scapular flap. The average age was 18.07 ± 10.14 years (range, 4-34 years) and 26.55 ± 13.05 years (range, 13-56 years), respectively. Surgery was performed as a primary or secondary reconstruction after a trauma by the same surgical team. RESULTS The mean size of defects was 9.73 ± 3.55 × 6.43 ± 2.8 cm in the contralateral free medial plantar flap group and 17.14 ± 6.84 × 11.41 ± 4.29 cm in the free dorsal flap group. All flaps survived in both groups. In the instep flap group, the appearance was satisfactory, the flap was durable, and tactile sensation was preserved in all patients, and none required a revision procedure. Two patients experienced delayed union of the donor-site grafted skin. In the dorsal flap group, 5 patients complained of a partial necrosis or delayed union at the recipient site, and 9 developed recurrent ulcerations over the weight-\bearing area. Five patients achieved only partial sensation in the flap. CONCLUSIONS The contralateral medial plantar flap provides superior appearance, duration, and sensation over distant muscle flaps, without recurrent ulcerations. However, dorsal myocutaneous flaps may be used as a substitute when the defects are beyond the maximum boundaries of the instep area or are combined with bone loss.

Abstract
INTRODUCTION Dangling protocols are known to vary by surgeon and center, and their specific regimen is often largely based on single surgeon or institutional experience. A systematic review was conducted to derive evidence-based recommendations for dangling protocols according to patient-specific and flap-specific considerations. METHODS A systematic review was performed using PubMed, Embase-OVID and Cochrane-CENTRAL. Study design, patient and flap characteristics, protocol details, dangling-related complications, and flap success rate were recorded. Studies were graded using the Oxford Center for Evidence-Based Medicine Levels of Evidence Scale. Data heterogeneity precluded quantitative analysis. RESULTS Eleven articles were included (level of evidence (range):IIb-IV; N (range):8-150; age (range):6-89). Dangling initiation, time, and frequency varied considerably. Flap success rate ranged from 94 to 100%. Active smoking, diabetes, and hypertension are associated with characteristic physiologic changes that require vigilance and potential protocol modification. Early dangling appears to be safe across a variety of free flap locations, sizes, and indications. Axial fasciocutaneous flaps may tolerate more aggressive protocols than muscular flaps. While flaps with single venous anastomosis tolerate dangling, double venous or flow-through anastomoses may provide additional benefit. Major limitations included small sample sizes, uncontrolled study designs, and heterogeneous patient selection, dangling practices, monitoring methods, and outcome measures. CONCLUSIONS Significant heterogeneity persists in postoperative dangling protocols after lower extremity microvascular reconstruction. Patient comorbidities and flap characteristics appear to affect tolerance to dangling. We propose two different standardized pathways based on risk factors. Clinical vigilance should be exercised in tailoring lower extremity protocols to patients' individual characteristics and postoperative course.

Abstract
BACKGROUND Traumatic lower extremity injuries involving the foot and ankle can have devastating consequences and represent a complex reconstructive challenge. To date, there are limited reports on microsurgical reconstruction for foot and ankle defects in children. This study aims to evaluate clinical and functional outcomes of free flaps for pediatric foot and ankle injuries. METHODS This is a retrospective review of patients undergoing free flaps for traumatic foot and ankle defects at a pediatric trauma center between 2000 and 2015. Patients with less than 5-year follow-up were excluded. Demographics, clinical characteristics, and postoperative outcomes were evaluated. RESULTS Thirty patients undergoing 30 flaps were analyzed. The mean age was 11.9 years (range: 2 to 17 years). Muscle flaps (n = 21, 70%) were more common than fasciocutaneous flaps (n = 9, 30%). Limb salvage with functional ambulation was achieved in 96.7% of patients (n = 29). The complication rate was 33.3% (n = 10), with wound breakdown (n = 6, 20.0%) as most common feature. There were no significant differences in limb salvage, total or partial flap loss, fracture union, and donor-site complications based on flap type. Fasciocutaneous flaps were more likely to require revision procedures for contour compared with muscle flaps (55.6 vs. 9.5%, p = 0.013). Mean follow-up was 8.5 years. CONCLUSION Microsurgical reconstruction of pediatric foot and ankle defects results in high rates of limb salvage. A defect- and patient-centered approach to reconstruction, emphasizing durable coverage and contour, is critical to facilitating ambulation and ensuring favorable long-term functional outcomes.

Abstract
The clinical management of large bone defects continues to be a difficult clinical problem to manage for treating surgeons. The induced membrane technique is a commonly employed strategy to manage these complex injuries and achieve bone union. Basic science and clinical evidence continue to expand to address questions related to the biology of the membrane and how interventions may impact clinical outcomes. In this review, we discuss the basic science and clinical evidence for the induced membrane technique as well as provide indications for the procedure and technical tips for performing the induced membrane technique.

Abstract
Fracture-related infection (FRI) is one of the most challenging complications following operative management of fractures. It can have profound implications for the patient, can be associated with considerable morbidity and often lead to impaired outcomes. There are significant healthcare-related costs. In recent years, there has been significant progress towards developing preventative strategies. Furthermore, diagnostic algorithms and management protocols have recently been reported. Lack of a strong evidence base has previously hindered efforts to implement these and develop established standards of care. There are multiple aspects of care that need to be considered and a multi-disciplinary approach is recommended. In this narrative review, we present the most up-to-date recommendations in the prevention, diagnosis and management of FRI.

Muscle Cuff in Distal Pedicled Adipofascial Sural Artery Flaps: A Retrospective Case Control Study. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2021; 9:e3464.

Abstract
Background: Amputation after open tibial fracture occurs in 3% of cases. The rate increases when flap reconstruction is required. The standard care involves microsurgical tissue transfer although the pedicled reverse sural artery adipofascial flap (PRSAF) is a local alternative in patients endangered by a prolonged operative time. Incorporation of a gastrocnemius muscle cuff in this flap can be used to fill dead space and increase healing potential. Literature shows superior survival rates for both PRSAF and inclusion of a muscle cuff in comparison with the cutaneous version. The aim of the study was to compare the outcome of the PRSAF and the musculoadipofascial version (PRSMAF). We hypothesize that the PRSMAF provides similar lap viability and flap-related complication rates as does the adipofascial version. The muscle component may reduce the long-term osteomyelitis rate. Methods: Patients were evaluated retrospectively after reconstruction with either PRSAF or PRSMAF. Preoperative osteomyelitis, flap survival, complications and osteomyelitis clearance were analyzed. Results: The study shows preliminary results supporting the potential use of the PRSMAF. We compare either 23 PRSMAF or 20 PRSAF flaps. We found no statistically significant differences in flap survival or in complication rate. Conclusions: Although the anatomical situation may sometimes dictate the use of a free flap, a technically less-complicated option may in some cases offer a viable alternative. This study shows that the PRSMAF can serve as an alternative for complex bone defects in the limb, though it does not provide statistical improvement to the PRSAF.

Abstract
BACKGROUND We aimed to compare different methods to treat lower leg soft tissue defects with tibia fracture using free flaps and pedicled flaps. We also highlighted the aesthetic outcome after using 1-stage secondary debulking procedure for tibia area. PATIENTS AND METHODS From December 2000 to March 2017, 83 patients with lower leg defects and tibia fractures were reconstructed using 71 free flaps and 12 pedicled flaps. One-stage secondary debulking procedures were performed for 39 patients after flap reconstruction. Infection control and aesthetic outcomes using 5-point Likert scale were reviewed after a 16-month follow-up. RESULTS Twenty-five myocutaneous free flaps, 45 fasciocutaneous free flaps, 1 fibula free flap, 12 pedicled flaps of which 8 were distally based sural artery flaps, and 4 medial gastrocnemius flaps were used. The flap survival rate was 100%. There was no recurrence of osteomyelitis in any patient after reconstruction with any of these flaps. Using a 5-point Likert scale, performance of a 1-stage secondary debulking procedure showed statistically significant difference in terms of contour, color, and texture compared with the group without debulking procedure. CONCLUSIONS The use of free flaps and pedicled flaps in the reconstruction of lower leg defects with tibia fracture is reliable and results in good infection control. A 1-stage secondary debulking procedure delivers excellent long-term aesthetic outcome after reconstruction of the tibia area.

Abstract
Improved knowledge of vascular anatomy has enabled surgeons to preoperatively identify perforators and design free-style flaps based on that perforator. Options for choosing the optimal donor site tissues are increased with the free-style technique. This reduces donor site morbidity while providing the same reconstructive success as traditional free skin flaps. The free-style technique allows the surgeon to successfully complete reconstruction when aberrant anatomy is encountered. With the necessary skills in perforator flap dissection and supermicrosurgery, the armamentarium of the reconstructive microsurgeon has been expanded with the introduction of free-style perforator free flaps.

Abstract
Lower limb salvage after major trauma is a complex undertaking. For patients who have suffered multi-level trauma to their lower limb we postulated that pelvic injury or ipsilateral lower limb injury proximal to the site of a free flap may increase the rate of post-operative complications. All patients who underwent lower limb free flap reconstruction as a result of acute trauma between January 2010 and December 2017 were included. The patients were divided into the study group (50 patients), who sustained a lower limb or pelvic injury proximal to the free flap site, and control group (91 patients) who did not sustain proximal lower limb or pelvic trauma. Complication rates were compared between the two groups. Overall, the proximal trauma group anastomotic thrombosis rate of 18.0% was significantly higher than the control group thrombosis rate of 2.2%. There was no statically significant difference in rates of hematoma, swelling or infection. Flap loss rate in the proximal trauma group was 4.0%, compared to the control group at 2.2%. All patients with a failed flap went onto have a successful reconstruction with a subsequent flap in the acute admission and there were no amputations. In the proximal injury study group despite the significantly increased rate of microvascular thrombosis requiring revision, the ultimate primary free flap survival rate was still 96%. Overall, severe coexisting proximal trauma predicted a higher venous microvascular complication rate but was not a contraindication to limb salvage.

Abstract
Advancements in microsurgery have made lower extremity reconstruction possible even after major soft tissue loss or tibial nerve disruption. There is an ongoing paradigm shift in the indications for amputation versus salvage and in flap selection protocols for different areas of the lower extremity. Initial evaluation, patient selection, triage, and timing of reconstruction are essential factors that can influence functional and aesthetic outcomes. The emergence of perforator flaps and the application of new concepts such as free-style flaps, propeller perforator flaps, thinning of free flaps, and supermicrosurgery have provided reconstructive surgeons with many techniques to decrease donor-site morbidity and improve outcomes. This includes options for reconstruction on extremities with single or no adequate runoff vessels. We present a review of the major advancements in reconstructive surgery for salvage of the traumatic lower extremity.

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
In the diabetic and peripheral vascular disease population there is a high risk of further amputation following a primary amputation. Amputation surgery is often approached negating the biomechanics of the lower extremity leading to complications or additional surgery. Implementing appropriate tendon balancing of stump and applying orthoplastic techniques will improve outcomes. This article introduces the basic techniques to a wider audience of foot and ankle surgeons. Specifically, this article is intended to be a descriptive guide for the use of tendon balancing and intrinsic muscle advancements in the various levels of foot amputations.

Abstract
BACKGROUND Radiation therapy causes histopathologic changes in tissues, including fibrosis, loss of tissue planes, and vascular damage, which can lead to chronic wound formation. Patients with nonhealing, irradiated wounds and comorbidities that affect microvasculature suffer a "double hit", which leads to delayed wound healing. Local wound care and grafts are commonly insufficient. In this study, we evaluated limb salvage outcomes and long-term complications after free tissue transfer (FTT) in patients with chronic, irradiated leg wounds. METHODS We retrospectively reviewed patients with irradiated lower extremity wounds who underwent FTT from 2012 to 2017. Primary outcomes included limb salvage, ambulation, and overall flap success. Reconstruction involved complete excision of irradiated tissue and coverage with well-vascularized tissue. RESULTS Seven free flaps in six patients were identified. Average age was 68.4 years and average BMI was 27.8 kg/m2. Comorbid conditions included hypertension (57.1%), peripheral vascular disease (57.1%), underlying hypercoagulability (42.9%), diabetes (14.3%), and tobacco use (14.3%). Wounds were present for an average of 25.5 months prior to FTT. Donor sites included anterolateral thigh (71.4%), vastus lateralis (14.3%), and latissimus dorsi (14.3%). Overall flap success rate was 100% with one patient requiring reoperation for dehiscence. Limb salvage rate was 85.7% with one patient undergoing elective amputation due to pain. All patients could ambulate (one used a prosthesis) at a mean follow-up time of 1.4 years. CONCLUSIONS Radiation therapy in a comorbid population often leads to the formation of chronic nonhealing wounds. We advocate for earlier consideration of FTT to provide healthy vascularized tissues, thereby avoiding prolonged wound care and patient burden. Successful limb salvage outcomes can be achieved.

Abstract
BACKGROUNDS Chronic osteomyelitis is a major challenge in orthopaedic surgery; it is the result of open fracture, periprosthetic infection and septic arthritis. Osteomyelitis leads to fracture nonunion. The treatment of bone infection and infected nonunion consists primarily of the complete removal of infected and avascular bone and soft tissue from the surgical site, followed by local and systemic pathogen-specific antibiotic therapy and temporary stabilisation, but may lead to massive skeletal and soft tissue defects. The use of free or pedicled vascularised bone transfers and callus distraction techniques (bone transport) has been recommended for large bone defects. The aim of this study is to evaluate the results of patients affected by infected non-unions of the lower limbs, treated with a corticoperiosteal flap from the medial femoral condyle and to investigate the donor site morbidity of this flap. MATERIALS AND METHODS The patients were 11 males (average age of 45.6 years), who presented a nonunion of the tibial diaphysis in 7 cases and non-union of femoral diaphysis in 4 cases, treated with free or pedicled corticoperiosteal flap. In all patients, surgical debridement was performed before the flap of infected bone and soft tissues that would not contribute to wound healing. Clinical and radiographic evaluations of the recipient site were performed. Preoperative and postoperative X-ray and MRI scans after the 3-year follow-up of the donor site were performed, in order to observe possible bone restoration and any complications. RESULTS The patients reported complete clinical and radiographic bone healing in 90.9 % of cases. As regards donor site, there were no differences between the medial femoral donor condyle compared to the contralateral site, due to complete regeneration of donor site bone. MRI investigation showed complete restoration of the donor site with vascularised bone in all patients. CONCLUSIONS Our results suggest that the use of bone flaps for the treatment of infected non-unions is an effective procedure, that must be performed after accurate debridement of the non-union site. The corticoperiosteal flap seems to have few morbidities on the donor site and a high percentage of successful bone healing.

Emergency Repair of Severe Limb Injuries With Free Flow-Through Chimeric Anterolateral Thigh Perforator Flap. Ann Plast Surg 2020; 83:670-675. [PMID: 31233403 DOI: 10.1097/sap.0000000000001913] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/26/2022]
Abstract
BACKGROUND Complex limb trauma often involves both soft tissue and vascular defects, and is challenging for surgeons. The traditional musculocutaneous flap cannot achieve a 3-dimensional wound repair. Here we report our experience with a single-stage reconstruction and revascularization performed on complex extremity injuries using a free flow-through chimeric anterolateral thigh perforator (ALTP) flap. PATIENTS AND METHODS Seventeen patients (16 men; aged 19-55 years) with complex soft tissue defects attended our hospital from January 2010 to November 2017. All patients underwent reconstruction based on free flow-through chimeric ALTP flap for complex injuries in their extremities. The wound size ranged from 16 × 8 to 45 × 30 cm. The injured artery was flow-through anastomosed with the descending branch of the lateral femoral circumflex artery to regain blood flow. The muscle flap was used to fill the deep dead space on the injury site. The skin and fascial flaps were used for superficial cover. The donor site defects were sutured directly in 6 patients; simultaneous skin grafts were applied in the remaining 11 patients. RESULTS The ALTP flaps survived in 15 patients. Failure necessitated limb amputation in 2 patients. Six patients received both skin and fasciae flaps; 11 received flaps comprising the skin, fasciae, and vastus lateralis muscle. Partial necrosis after skin grafting was observed in 11 patients, and the wounds healed either by dressing change (1 patient) or second skin graft (10 patients). All donor sites healed without complications. All patients were followed up for 5 to 60 months (mean, 21.8 months). CONCLUSIONS The flow-through chimeric ALTP flap can be used for 1-stage reconstruction of 3-dimensional soft tissue defects and vascular gap. It is feasible for managing complex injuries of both the upper and lower extremities in emergency settings.

Abstract
BACKGROUND The microsurgical reconstruction of complex lower limb defects has become a routine procedure with high success rates. The emphasis has changed from ensuring flap 'success' to providing a reconstruction, which is also aesthetically pleasing. The aim of this study was to compare patients' satisfaction with aesthetic outcomes, following muscle or fasciocutaneous free flap reconstruction to the lower limb. METHODS Data were collected retrospectively between July, 2013 and May, 2018 at a single institution. The inclusion criteria were adult patients who had successful free tissue transfers to the lower limb following any aetiology. A Likert Scale questionnaire was sent to all patients who met these criteria. The questionnaire included questions related to the reconstruction and donor site. RESULTS Questionnaires were sent to 83 patients who met the inclusion criteria. Forty-seven (57%) patients responded, of which 22 (47%) underwent reconstruction with muscular flap and 25 (53%) with fasciocutaneous flap. A statistically significant difference between the two groups was found in relation to flap texture (p = 0.003). Patients with fasciocutaneous flap reconstruction being more satisfied. No significant difference was observed for contour, similarity to the contralateral side, bulkiness of flap, colour match, scar, or overall appearance. The comparison of donor site results revealed no significant difference between the two groups CONCLUSIONS: Despite increase in success in lower extremity reconstruction, many patients still find aesthetic results suboptimal and this affects an individual's global sense of well-being. Aesthetic restoration should be viewed as an integral part of lower limb reconstruction. LEVEL OF EVIDENCE Therapeutic, III.

New insights from a cohort study of the anterolateral thigh flap (ALT) versus ALT-Vastus lateralis flaps. J Plast Reconstr Aesthet Surg 2020; 74:268-276. [PMID: 33020036 DOI: 10.1016/j.bjps.2020.08.097] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2019] [Revised: 06/19/2020] [Accepted: 08/26/2020] [Indexed: 10/23/2022]
Abstract
The benefits of the muscle in open lower limb fractures remain to be determined. This study compared statistically equivalent groups of open tibial fractures treated by free anterolateral thigh (ALT) flaps or ALT flaps incorporating muscle (ALT-Vastus lateralis/ALT- VL). Method and Results: Chang Gung Memorial Hospital, Taiwan, 2004-2008, 49 free flaps in open lower limb fractures (38 open tibial) were specifically reconstructed with free ALT or ALT-VL flaps. Risk factors for non-union: equivalent between the two groups, with no differences in smoking, steroids, diabetes, time to flap and the AO classification of soft tissue and bone injury. Comparison of union rates: no difference was noted between groups in the Radiographic Union Score in Tibial Fractures (RUST) at 3, 6, 9 and 12 months. The only factor significantly associated with non-union was presence of a SPRINT trial defined 'critical' bone defect with odds ratio 14.4 (95% CI 1.36 - 131.5), with no association with AO bone classification, flap type, comorbidity or flap size. Patient-reported outcomes: the ALT-VL group showed improved patient satisfaction (p = 0.01, Cohen's d = 1.1). Functional outcomes (Enneking score) were not statistically significant, but the ALT-VL group trended towards significance in function and skin quality domains. Conclusions: Based on the results of this study, one can conclude that the degree of bone injury (specifically a 'critical' defect) is of greater relevance than flap choice with regard to fracture consolidation. Muscle does not result in improvements to union, the speed of union or deep infection. However, better PROMs may be related to the inclusion of the muscle around the fracture site.

Abstract
Wound healing and coverage of soft tissue defects of distal tibia are challenging. Free tissue transfer is treatment of choice for distal tibial defects. However, resources for free tissue transfer are not readily available and they increase morbidity to host. Local and regional flaps play a key role in management of these defects with less demanding or specialized requirements. The soleus muscle flap is the workhorse flap for midtibia soft tissue defects and is used in reverse fashion to reach the distal third of the tibia. Despite minor complications, distally based medial hemisoleus flap is reliable in limb salvage cases.

Abstract
Immune reactions are a key factor in determining the destiny of bone substitute materials after implantation. Macrophages, the most vital factor in the immune response affecting implants, are critical in bone formation, as well as bone biomaterial-mediated bone repair. Therefore, it is critical to design materials with osteoimmunomodulatory properties to reduce host-to-material inflammatory responses by inducing macrophage polarization. Our previous study showed that calcium silicate (CS) bioceramics could significantly promote osteogenesis. Herein, we further investigated the effects of CS on the behavior of macrophages and how macrophages regulated osteogenesis. Under CS extract stimulation, the macrophage phenotype was converted to the M2 extreme. Stimulation by a macrophage-conditioned medium that was pretreated by CS extracts resulted in a significant enhancement of osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs), indicating the important role of macrophage polarization in biomaterial-induced osteogenesis. Mechanistically, oncostatin M (OSM) in the macrophage-conditioned medium promoted osteogenic differentiation of BMSCs through the ERK1/2 and JAK3 pathways. This in vivo study further demonstrated that CS bioceramics could stimulate osteogenesis better than β-TCP implants by accelerating new bone formation at defective sites in the femur. These findings improve our understanding of immune modulation of CS bioactive ceramics and facilitate strategies to improve the in vitro osteogenesis capability of bone substitute materials. Calcium silicate (CS) bioceramics significantly promoted osteogenesis by the regulating of macrophage polarization. ERK1/2 and JAK3 pathways mediated the osteogenic differentiation stimulated by CS. CS played a promising osteoimmunomodulatory agent for bone induction.

Abstract
Cutaneous substance loss in the leg is frequent; more often than not, it is trauma-related. It calls for complex management and necessitates the application of all current reconstruction techniques, particularly microsurgery. As regards treatment, the available therapeutic arsenal is highly diversified, ranging from a simple free flap skin graft to local and locoregional flaps. During reconstruction, the surgeon is subjected to several constraints insofar as the objectives of the operation are esthetic as well as functional. Ideally, the fineness of the skin covering the anterior side of the leg will have been scrupulously respected. Reconstruction is aimed at producing a stable and reliable cutaneous envelope while limiting the morbidity of the donor site. The development of free perforator flaps corresponds to these two criteria by producing a fine flap adapted to the cutaneous thickness of the leg and limiting any functional and esthetic sequelae at the donor site.

Abstract
Abstract
Background A 36-year-old male was involved in a motor vehicle accident, presenting with a Guistillo's IIIB crush injury to the upper extremity. A severely comminuted ulnar fracture resulted in a 10-cm bone defect with significant overlying soft tissue injury.
Methods The injury resulted in a wide zone of injury with inadequate collateral vascularity at the level of the elbow and distal viability dependent on the brachial artery. An osteocutaneous free fibular flap and fasciocutaneous anterolateral thigh flap were used to reconstruct the defect with both flaps anastomosed in an end-to-side fashion to the brachial artery.
Results The upper extremity was successfully salvaged, and the patient discharged from hospital at postoperative day 10. Both free flaps survived with no donor or recipient site complications at a follow-up period of 2 years.
Conclusion The case illustrates the challenges inherent to significant Guistillo's IIIB injuries with insufficient recipient vessels over a large zone of injury. While performing anastomoses outside the zone of injury is preferred, this case demonstrates the success of performing multiple anastomoses to the brachial artery in an end-to-side fashion within the zone of injury.

Abstract
OBJECTIVE The purpose of this study was to evaluate the results of the medial adipofascial flap (MAF) in infected tibia fractures reconstruction and to identify criteria for success or failure. PATIENTS AND METHODS Fifty-nine patients treated with a MAF were enrolled. Age, BMI, tobacco use and bone status were recorded. Early and late postoperative complications were assessed. Bone healing and flap success were systematically evaluated at 12 months. RESULTS Tibia fractures were initially open in 48 cases (81%) and closed in 11 cases (19%). Infection was acute (<30 days) in 9 cases (15%) and chronic in 50 (85%). Thirty-one patients (53%) experienced no early postoperative complications (<30 days). There were 10 (17%) cases of necrosis of the skin graft, 2 (3%) cases of necrosis and 4 (7%) haematomas in the harvesting area, 7 (12%) cases of partial flap necrosis at its tip and 4 (7%) flap failures. None of the criteria was statistically correlated with the occurrence of a complication. At 12 months, 53 flaps (90%) were successful. Immediate skin graft were significantly correlated with flap success (P=0.05). Forty-six patients (78%) had complete bone healing documented by CT scan. CONCLUSION The MAF provides a reliable alternative for lower leg reconstruction. Its major advantages are sparing of the major leg vessels, no donor site morbidity and relatively easy and rapid dissection.

Abstract
BACKGROUND In recent years, the progress of anatomical knowledge and microsurgical techniques, in particular the development of perforator flaps, has risen the number of flaps available for lower leg reconstruction. The esthetic consequences of flap choice and harvest do have an impact on patients' quality of life. Nowadays, more researchers evaluate the esthetic changes following lower limb reconstruction. OBJECTIVES This review aims to summarize the available evidence on the esthetic outcome of lower limb reconstruction. DATA SOURCES A systematic review was planned to identify the most relevant indexed articles on this subject. The search was performed on Pubmed database without date of publication limits. STUDY ELIGIBILITY CRITERIA All papers about reporting information about the esthetic outcome of lower limb reconstruction were selected. Case reports and the articles not including specific information about complications, secondary procedures, and outcomes were excluded. The articles were categorized according to their topic and date of publication. The full texts of all the articles were obtained and read thoroughly. The references for each article were screened to identify articles that were eventually left outside our database search. PARTICIPANTS, AND INTERVENTIONS One hundred and eight articles were retained for the definitive review. Eleven review articles were kept because they represented a good source of information. Thirty-three articles were added after reading the full texts. The articles appear highly heterogeneous and at, this stage, only a critical and qualitative analysis could be performed. RESULTS We found information about 7895 lower reconstructions, 1295 local flaps, 6546 free flaps. LIMITATIONS The esthetic evaluation is intrinsic subjective. Many psychological and cultural factors influence both the patient and the surgeon. There is not a validated assessment tool for the esthetic outcome of lower leg reconstruction. Therefore, no quantitative analysis was performed. CONCLUSIONS Some ancient techniques are today obsolete, like the rectus abdominis free muscle flaps and perhaps free forearm flap, others are always useful, like gracilis and latissimus dorsi free flap. ALT flap is the most versatile perforator flap today available, but the SCIP flap is gaining the favor of a growing number of surgeons. Local flaps will be always performed with success but their indications should not be pushed beyond the medium-size defects. The best cosmetic outcome for each patient cannot necessarily be obtained neither with the easiest techniques nor with the most technically demanding ones. It is necessary to develop validated tools to assess the cosmetic outcome of lower limb reconstruction.

Abstract
Fracture-related infection (FRI) remains a challenging complication that creates a heavy burden for orthopaedic trauma patients, their families and treating physicians, as well as for healthcare systems. Standardization of the diagnosis of FRI has been poor, which made the undertaking and comparison of studies difficult. Recently, a consensus definition based on diagnostic criteria for FRI was published. As a well-established diagnosis is the first step in the treatment process of FRI, such a definition should not only improve the quality of published reports but also daily clinical practice. The FRI consensus group recently developed guidelines to standardize treatment pathways and outcome measures. At the center of these recommendations was the implementation of a multidisciplinary team (MDT) approach. If such a team is not available, it is recommended to refer complex cases to specialized centers where a MDT is available and physicians are experienced with the treatment of FRI. This should lead to appropriate use of antimicrobials and standardization of surgical strategies. Furthermore, an MDT could play an important role in host optimization. Overall two main surgical concepts are considered, based on the fact that fracture fixation devices primarily target fracture consolidation and can be removed after healing, in contrast to periprosthetic joint infection were the implant is permanent. The first concept consists of implant retention and the second consists of implant removal (healed fracture) or implant exchange (unhealed fracture). In both cases, deep tissue sampling for microbiological examination is mandatory. Key aspects of the surgical management of FRI are a thorough debridement, irrigation with normal saline, fracture stability, dead space management and adequate soft tissue coverage. The use of local antimicrobials needs to be strongly considered. In case of FRI, empiric broad-spectrum antibiotic therapy should be started after tissue sampling. Thereafter, this needs to be adapted according to culture results as soon as possible. Finally, a minimum follow-up of 12 months after cessation of therapy is recommended. Standardized patient outcome measures purely focusing on FRI are currently not available but the patient-reported outcomes measurement information system (PROMIS) seems to be the preferred tool to assess the patients' short and long-term outcome. This review summarizes the current general principles which should be considered during the whole treatment process of patients with FRI based on recommendations from the FRI Consensus Group.Level of evidence: Level V.

Abstract
Neoadjuvant treatment and surgical resection for sarcoma patients can often leave devastating wounds necessitating soft-tissue coverage in the form of free flaps. There is still debate as to the optimal flap for reconstruction of defects in irradiated fields. We aim to describe our experiences with free fasciocutaneous and free muscle flaps for sarcoma reconstruction in the setting of radiation therapy. A retrospective chart review was conducted encompassing all patients requiring soft-tissue reconstruction secondary to sarcoma resection from January 2010 to June 2019. Patient characteristics, flap viability and post-operative healing outcomes were all recorded and examined. In total, 49 patients who underwent 51 free-flaps were identified. Of these, 30 flaps were fasciocutaneous, while 21 were muscle-based. Most patients received pre-operative radiotherapy (76.5%), although these rates were not different between groups of flap type, and had no significant association with post-operative outcomes. Complication rates (31.3%) and re-operative rates (21.6%) were also comparable between flap types. Diabetes mellitus was significantly associated with delayed wound healing (p < .016), while the presence of peripheral vascular disease had a significant association with post-operative infection (p < .006). This study shows that free fasciocutaneous and free muscle-based flaps are both viable options for soft-tissue reconstruction demanded by sarcoma resection, even in the setting of radiation. Peripheral vascular disease and diabetes mellitus may confer increased wound complications.

Abstract
Purpose: This study aims to assess the efficacy and safety of Pelnac dermal regeneration template assisted by vacuum sealing drainage (VSD) and a split-thickness skin graft to cover the large skin and soft-tissue defects at foot and ankle. Methods: This study began from March 2013, up to February 2017. A total of 16 patients met the inclusion and exclusion criteria and were included. For every patient, 2 separate operations were performed, the first being thorough debridement of necrotic tissues immediate coverage of VSD at continuous negative pressure suction, and the second being the autologous split-thickness skin graft. At each follow-up, relevant data were documented. Results: The average follow-up was 16.5 months (range, 12 to 42 months). No infections, hematoma, or seroma were observed. 13 out of 16 patients had a complete skin graft "take" (100%). Patients' satisfaction of esthetic appearance was 76.5 ± 5.2/100. The VSS value was 2.2 ± 2.1, representing a good result. Regarding the sensory recovery, the response "normal or near normal" could be obtained in 14/16 patients. Mean AROM for extension/flexion of the ankle was 48.5 ± 4.8° (range 35-62°), and 93.7% (15/16) of patient could obtain a satisfying functional result. Conclusions: Our report indicated Pelnac provided an effective method for management of complex wounds with underlying bone or tendons exposed.

Abstract
Osteocutaneous reconstruction can be challenging because of concomitant injuries and limited donor sites. There is a paucity of data on limb salvage outcomes following combined soft-tissue reconstruction and bone transport or Masquelet procedures. The authors reviewed a consecutive series of open tibia fracture patients undergoing soft-tissue reconstruction with either distraction osteogenesis or Masquelet technique. Endpoints were perioperative flap complications and bone union. Fourteen patients with Gustilo type IIIB open tibia fractures were included. Half of the group received muscle flaps and the remaining half received fasciocutaneous flaps. Ten patients (71.4 percent) underwent distraction osteogenesis and the remaining patients underwent Masquelet technique. Average bone gap length was 65.7 ± 31.3 mm (range, 20 to 120 mm). In the bone transport group, the average external fixation duration was 245 days (range, 47 to 686 days). In the Masquelet group, the average duration of the first stage of this two-stage procedure (i.e., time from cement spacer placement to bone grafting) was 95 days (range, 42 to 181 days). Bone union rate, as determined by radiographic evidence, was 85.7 percent. There was one complete flap failure (7.1 percent). One patient underwent below-knee amputation after failing bone transport and developing chronic osteomyelitis and subsequent infected nonunion. Our case series demonstrates that nonosteocutaneous flap methods of limb reconstruction are a viable option in patients with segmental long bone defects, with a bone union rate of 85 percent and a limb salvage rate over 90 percent in patients with Gustilo type IIIB fractures. CLINICAL QUESTION/LEVEL OF EVIDENCE:: Therapeutic, IV.

Microsurgery 2020; 40:473-478. [PMID: 31912944 DOI: 10.1002/micr.30556] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2019] [Revised: 11/11/2019] [Accepted: 12/26/2019] [Indexed: 11/11/2022]
Abstract
BACKGROUND Free flap reconstruction after lower extremity trauma remains challenging with various factors affecting overall success. Increasing defect and flap size have been demonstrated to be a surrogate for overall injury severity and correlated with complications. In addition, larger free flaps that encompass more tissue theoretically possess high metabolic demand, and may be more susceptible to ischemic insult. Therefore, the purpose of our study was to determine how flap size affects microsurgical outcomes in the setting of lower extremity trauma reconstruction. METHODS Retrospective review of 806 lower extremity free flap reconstructions performed from 1979 to 2016 among three affiliated hospitals: a private university hospital, Veterans Health Administration Hospital (VA), and a large, public hospital serving as a level 1 trauma center for the city. Soft tissue free flaps used for below the knee reconstructions of traumatic injuries were included. A receiver operating curve (ROC) was generated and Youden index was used to determine the optimal flap size for predicting flap success. Based on this, flaps were divided into those smaller than 250 cm2 and larger than 250 cm2 . Partial flap failure, total flap failure, takebacks, and overall major complications (defined as events involving flap compromise) were compared between these two groups. Multivariate logistic regression was performed to determine whether flap size independently predicts complications and flap failures, controlling for injury-related and operative factors. RESULTS A total of 393 patients underwent lower extremity free tissue transfer. There were 229 flaps (58.2%) with size <250 cm2 and 164 flaps (41.7%) ≥ 250 cm2 . ROC analysis and Youden index calculation demonstrated 250 cm2 (AUC 0.651) to be the cutoff free flap for predicting increasing flap failure. Compared to flaps with less than 250 cm2 , larger flaps were associated with increased major complications (33.6% vs. 50.0%, p = .001), any flap failure (11.8% vs. 25.0%, p = .001) and partial flap failure (4.8% vs. 14.6%, p = .001). Logistic regression analysis controlling for age, flap type, era of reconstruction, number of venous anastomoses, presence of associated injuries, presence of a bone gap, vessel runoff, and flap size identified increasing flap size to be independently predictive of major complications (p = .05), any flap failure (p = .001), partial flap failure (p < .001), and takebacks (p = .03). Subset analysis by flap type demonstrated that when flap size exceeded 250 cm2 , use of muscle flaps was associated with significantly increased flap failure rates (p = .008) while for smaller flap size, there was no significant difference in complications between muscle and fasciocutaneous flaps. CONCLUSION Increasing flap size is independently predictive of flap complications. In particular, a flap size cutoff value of 250 cm2 was associated with significantly increased flap failure and complications particularly among muscle-based flaps. Therefore, we suggest that fasciocutaneous flaps be utilized for injuries requiring large surface area of soft tissue reconstruction.

Comparison of Fasciocutaneous and Muscle-based Free Flaps for Soft Tissue Reconstruction of the Upper Extremity. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2019; 7:e2543. [PMID: 32537297 PMCID: PMC7288888 DOI: 10.1097/gox.0000000000002543] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2019] [Accepted: 10/02/2019] [Indexed: 10/28/2022]
Abstract
Soft tissue free flap reconstruction of upper extremities has proven to be reliable and essential for limb salvage and function. Nevertheless, comparative data regarding flap outcome are still lacking. The present study aimed to compare procedural features and individual complication rates of different free flaps used for upper extremity reconstruction. Methods The authors evaluated retrospectively the results of 164 free flaps in 149 patients with upper extremity defects. Chart reviews were performed from April 2000 to June 2014, analyzing flap choices, complication, and success rate assessment for patients >18 years old, with a soft tissue defect of the upper extremity. Chosen flap types were classified as fasciocutaneous (including adipocutaneous) and muscle-based, respectively. We comparatively analyzed total flap loss, flap survival after microsurgical revisions, and susceptibility rates for thromboses rates and partial flap necrosis. Results Defect size was larger when muscle-based flaps were used (231 ± 38.6 versus 164 ± 13.7 cm2, P < 0.05). Outcome analysis revealed a tendency towards higher arterial thrombosis rates for muscle flaps (10.2% versus 4.3%) and venous thrombosis rates for fasciocutaneous flaps (2% versus 7%). Total flap loss (6.1% versus 7.8%) and flap survival after vascular revisions (75% versus 70.6%) showed comparable rates. Partial flap necrosis was generally higher in muscle-based flaps (22.4% versus 8.6%, P = 0.02) with impact on patients' hospital stay (37.2 ± 4.69 and 27.11 ± 1.62 days, n = 115, P = 0.01), while no differences in partial necrosis rates were noted in flaps larger than 300 cm2 (25% versus 10%, P = 0.55). There was a trend over time towards using fasciocutaneous-based flaps more frequently with a final overall percentage of 83.7% between 2012 and 2014. Conclusions Microsurgical tissue transfer to the upper extremity is safe and reliable, but flap-type specific procedural and measures should be taken into consideration. Total flap loss as well as flap survival after microsurgical revisions are not altered between these flaps. They differ, however, in their susceptibilities for thromboses rates, partial flap necrosis and thus require individual risk stratification and flap placement.

Abstract
The purpose of this study was to assess the efficacy and safety of Pelnac and split-thickness skin graft for management of complex wound with underlying bone/tendon exposure at forearm and hand.This is a prospective study, beginning from March 2013 up to May 2017. There were 13 patients, with age of 31.2 years. All of them underwent the staged Pelnac and split-thickness skin graft to manage the complex wound with bone/tendon. Postoperatively, scheduled follow-up was conducted.The average follow-up was 15 months. There were no infections, wound necrosis, hematoma, or seroma during the phase when Pelnac was applied. There was 100% "take" of the Pelnac in 12/13 patients. In 11 patients, there was complete skin graft "take". Patients' satisfaction for the esthetic appearance of the grafted area was 75.0 ± 8.5/100. The VSS value was 2.9 ± 2.5. Regarding the sensory recovery, the response of "normal or near normal" could be obtained in 7/13 patients, "slight loss" in 5 patients and "significant loss" in 1 case. The average DASH score was 27.2 ± 18.5, and most patients (12/13) could obtain an acceptable ability to perform the daily activities.Pelnac dermal template is a favorable alternative to flap reconstruction in the treatment of complex wound with underlying tissues exposure.

Abstract
The treatment of complex injuries of the lower extremities in geriatric and/or multimorbid patients requires optimized preoperative and perioperative management as well as differentiated and interdisciplinary surgical approaches. Timely and definitive treatment should be strived for to avoid longer periods of immobilization. Temporary external stabilization of complex fractures, when necessary, should be followed by permanent loading stable internal osteosynthesis as soon as possible. Accompanying soft tissue defects are reconstructed after wound débridement using the full armamentarium of plastic and reconstructive surgical procedures, including microvascular free flap. In the context of perfusion compromised soft tissue situations, negative pressure wound therapy can provide sterile temporary defect coverage and aid in preconditioning poorly vascularized tissue before definitive reconstruction. A clarification of the vascular status in geriatric patients is paramount and relevant perfusion disorders should be treated either by intervention or open surgery before complex reconstructive interventions. Close interdisciplinary coordination of the various surgical procedures is imperative in order to guarantee an optimized stable reconstructive outcome with acceptable patient risk. Taking these principles into account, the reconstruction of complex trauma to the extremities can be carried out even in geriatric or multimorbid patients in specialized interdisciplinary surgical centers with excellent functional results.

Abstract
Since the advent of microsurgery, and expanding expertise in the field, extensive traumatic wounds of leg have been managed successfully with free tissue transfer. Various patient-related factors may preclude the use of free flaps even in units with available expertise and infrastructure. It is in such situations that the "cross-leg flap" comes into play. In these cases, instead of attempting complicated anastomotic techniques or anastomosis in the zone of trauma, it is better to perform the simpler and more reliable cross-leg flap. In this study, we try to show the utility of a cross-leg flap based on a retrospective study of 198 patients who underwent cross-leg flap in our institute over a period of 15 years extending from November 2003 to March 2018. MATERIALS AND METHODS Case sheets of all patients who underwent cross-leg flap from November 2003 to March 2018 were reviewed. The location of defect in the leg, the indication for cross-leg flap, the pattern of cross-leg flap, and perioperative complications were noted. RESULTS A total of 198 patients underwent cross-leg flap for traumatic soft tissue injury of leg during this period. The most common reason for performing cross-leg flap was poor pulsatility of the recipient artery as seen intraoperatively, followed by the economics of the procedure wherein the initial cost of free flap was found significantly higher compared with cross-leg flap. All flaps survived with partial necrosis occurring in 23 patients. All flaps settled well by 2 years' time. Bony union/fracture healing evaluation was not a part of this study. CONCLUSION Cross-leg flap is still a useful tool for leg wound coverage even in microsurgical unit in situations precluding free flap coverage.
