Reconstruction of the Femoral Diaphysis Using the Vascularized Fibula Flap: A Case Report

The vascularized fibula flap is often utilized in various reconstructive surgeries to cover a bone or soft tissue defect due to its generous length, adequate vascularization, and the possibility of removal with minimal loss of limb function. We present a 32-year-old male patient with a 27-cm femoral diaphysis defect caused by a high-impact car accident, which led to multiple femoral fractures and was further complicated by osteomyelitis. Initial consultations with other physicians advised limb amputation as the sole approach due to the severity of the case and potential complications. Upon presentation at Kuzanov Clinic, the possibility of salvaging the limb using the vascularized fibula flap was proposed. A 27-cm fibula flap was harvested and transplanted to the femoral defect. Anastomosis was established between the vasculature of the flap and the recipient zone. A few months after the surgery, an upper fibular fracture occurred, which later healed, and the fibula hypertrophied. At a 10-year follow-up, the patient remains ambulatory, with limb shortening effectively managed with a custom shoe.

Vascularized Free Fibula Flap for Limb Salvage After Long Bone Tumor Resection in Pediatric Patients: A Single-Center Seven-Year Experience From a Developing Country

Background Pediatric long bone sarcomas pose significant challenges, requiring a delicate balance between oncological control and limb preservation. Limb salvage surgery has emerged as a preferred approach, with vascularized free fibula flap reconstruction showing promise in achieving favorable outcomes. The objective of this study was to evaluate the clinical outcomes of limb salvage surgery, including complication rates, functional outcomes, long-term survival, and disease recurrence. Method A retrospective analysis was conducted on pediatric patients undergoing limb salvage surgery for long bone sarcomas using vascularized free fibula flaps. Data from a single center's experience over a seven-year period were analyzed, including patient demographics, tumor characteristics, surgical techniques, complications, and functional outcomes. Follow-up assessments were performed regularly to monitor bone healing, disease recurrence, and functional recovery. Results Fifteen pediatric patients underwent limb salvage surgery with vascularized free fibula flap reconstruction, with a focus on 10 cases meeting inclusion criteria. Osteosarcoma was the most common histological diagnosis (seven, 70%), predominantly affecting the lower extremities (six, 60%). Surgical procedures varied based on tumor location, with most reconstructions utilizing osteocutaneous fibula flaps (eight, 80%). The flap survival rate was 10 (100%), with no instances of flap failure. Immediate complications occurred in three (30%) of cases, primarily surgical site infections, while one patient experienced delayed non-union and fracture requiring additional surgery. Functional outcomes were generally favorable, with seven (70%) of patients retaining functional limbs during follow-up. Conclusion In conclusion, our study demonstrates that vascularized free fibula flap reconstruction in pediatric long bone sarcomas can achieve high flap survival and acceptable short-term functional outcomes. Our series supports the technical feasibility of this approach, and delayed complications such as non-union and metastasis underscore the need for careful long-term surveillance and further prospective studies.

Physical Activity and Quality of Life After Distal Femur Tumor Resection and Limb Salvage

Background/Objectives: Distal femur tumor resection with limb salvage is a demanding procedure that offers hope for patients by preserving the limb rather than opting for amputation. While limb salvage can improve both physical function and psychological well-being, there's limited knowledge on how active patients remain afterward and how their Quality of Life (QoL) is affected, especially regarding physical activities and sports. This study investigates the quality of life of the patients through the development of motor activity, focusing on both physical and sporting activity of the above-mentioned individuals and their physical abilities to participate in activities of daily and sporting life after surgery. Methods: This study involved 16 patients aged 19-47 years who had undergone surgical resection and replacement of the distal femur for the treatment of sarcoma and were selected by random sampling from a total of 72 patients who had undergone a similar procedure. To explore the topic in depth, the researchers followed the triangulation method. From July 2023 to February 2024, we used surveys and interviews to explore their physical activity (PA) levels, sports participation, and QoL. This study included the International Physical Activity (PA) Questionnaire (IPAQ), the University of California and Los Angeles (UCLA) Activity Score, and semi-structured interviews. The data were analyzed using the statistical software packages SPSS 25 and Excel. Results: Most participants reported moderate to high levels of PA, according to IPAQ, and continued engaging in sports, with swimming, walking, and stair climbing being the most common activities. No significant relationship was found between their PA levels and factors such as age, BMI, or the side of the affected limb. Interviews showed that patients' motivation and their surgeon's guidance played key roles in their return to regular activities, though many exercised less frequently or intensely than recommended. Conclusions: Patients who undergo limb salvage surgery following distal femur tumor removal generally maintain a good level of physical activity, which supports their QoL. Encouraging these patients to stay active and even engage in sports appears feasible, especially when guided by medical professionals. These findings highlight the potential benefits of tailored rehab programs to improve long-term health and QoL in sarcoma survivors, although larger studies are needed for more comprehensive insights.

3D Bioprinting in Limb Salvage Surgery

With the development of 3D bioprinting and the creation of innovative biocompatible materials, several new approaches have brought advantages to patients and surgical teams. Increasingly more bone defects are now treated using 3D-bioprinted prostheses and implementing new solutions relies on the ability of engineers and medical teams to identify methods of anchoring 3D-printed prostheses and to reveal the potential influence of bioactive materials on surrounding tissues. In this paper, we described why limb salvage surgery based on 3D bioprinting is a reliable and effective alternative to amputations, and why this approach is considered the new standard in modern medicine. The preliminary results of 3D bioprinting in one of the most challenging fields in surgery are promising for the future of machine-based medicine, but also for the possibility of replacing various parts from the human body with bioactive-based constructs. In addition, besides the materials and constructs that are already tested and applied in the human body, we also reviewed bioactive materials undergoing in vitro or in vivo testing with great potential for human applications in the near future. Also, we explored the recent advancements in clinically available 3D-bioprinted constructs and their relevance in this field.

Comparison of safety and efficacy of femoropopliteal arterial disease using different dose drug-coated balloons: Systematic review and meta-analysis

BACKGROUND

Endovascular therapy with balloon percutaneous angioplasty (PTA) in the femoro-popliteal segment is frequently performed, however, long-term favorable outcomes and patency remain challenging, with restenosis rates reaching 60% post-standard balloon angioplasty. Drug-coated balloons (DCBs) have shown promise in improving these outcomes; Paclitaxel, used in DCBs, inhibits hyperplasia and smooth muscle cell proliferation, reducing restenosis; however, the optimal dose of Paclitaxel remains unclear, with high-dose (HD-DCB [>3 mg/mm2]) and low-dose (LD-DCB [<2.0 mg/mm2]) options available. This meta-analysis aims to compare the efficacy and safety of HD-DCB and LD-DCB in treating femoropopliteal arterial disease.

METHODS

We followed PRISMA guidelines and conducted a comprehensive search of PubMed, EMBASE, Cochrane, Scopus, and Mendeley up to May 27, 2024. We included randomized controlled trials and cohort studies comparing HD-DCB and LD-DCB in patients with femoropopliteal arterial disease. Data were extracted on baseline characteristics, outcomes, and study quality. The Newcastle-Ottawa Scale and ROB2 tool were used for bias assessment. Outcomes included overall survival (OS), limb salvage (LS), freedom from clinically driven target lesion revascularization (CD-TLR), and major amputation.

RESULTS

Six studies comprising 2563 patients were included. HD-DCB showed a significant benefit in limb salvage at 6 months (RR = 0.38, 95% CI = 0.18-0.78, p = .009) but not at 12 months (RR = 3.08, 95% CI = 0.14-67.13, p = .47). No significant difference was observed in overall survival between HD-DCB and LD-DCB at either 6 months (RR = 1.53, 95% CI = 0.25-9.57, p = .65) or 12 months (RR = 1.21, 95% CI = 0.17-8.84, p = .85). HD-DCB was associated with an increased risk of perioperative complications (RR = 1.90, 95% CI = 1.14-3.17, p = .01) and a higher, though not statistically significant, risk of major amputation (RR = 4.73, 95% CI = 0.54-41.52, p = .16).

CONCLUSION

HD-DCB may offer advantages in limb salvage over LD-DCB in the short term, but this comes with an increased risk of perioperative complications. These findings underscore the need for careful patient selection when considering HD-DCB for femoropopliteal artery disease.

Trabecular metal collars in endoprosthetic replacements: do they osseointegrate?

Aims

Limb salvage surgery (LSS) is the primary treatment option for primary bone malignancy. It involves the removal of bone and tissue, followed by reconstruction with endoprosthetic replacements (EPRs) to prevent amputation. Trabecular metal (TM) collars have been developed to encourage bone ingrowth (osseointegration (OI)) into EPRs. The primary aim of this study was to assess whether OI occurs when TM collars are used in EPRs for tumour.

Methods

A total of 124 patients from July 2010 to August 2021 who underwent an EPR for tumour under the West of Scotland orthopaedic oncology team were identified. Overall, 81 patients (65%) met the inclusion criteria, and two consultants independently analyzed radiographs at three and 12 months, as well as the last radiograph, using a modified version of the Stanford Radiological Assessment System.

Results

OI of the TM collar occurred in approximately 65% of patients at last radiograph. The percentage of patients with OI at three months (65.4%) reflected the 12-month (65%) and long-term (64.4%) follow-up. The median amount of OI across all radiographs was one at all three timepoints, with only five cases (11.1%) showing OI in all four zones at last radiograph. Radiolucency at the bone:collar junction was present in 23 cases (28.4%) at three months, but only four (6.7%) showed progression of this at 12 months. The interobserver reliability was found to be highly reliable in all parameters (p < 0.001).

Conclusion

OI occurs in approximately 65% of TM collars, and is similar at three months, 12 months, and last radiograph. The extent of OI at the bone:collar junction was found to have decreased at longer-term follow-up. Furthermore, radiolucency at the bone-collar impact junction does occur in some patients but only a low number will show radiolucency progression at longer-term follow-up.

Epidemiology and Impact of Limb Loss in the United States and Globally

The main causes of limb loss include trauma, complications from diabetes and peripheral arterial disease, malignancy, and congenital limb deficiency. There are significant geographic variations in the incidence of upper and lower, and major and minor limb loss worldwide. Limb loss is costly for patients and the health care system. The availability of orthotic and prosthetic services, along with cost of services, represents barrier to care and contributes to morbidity and mortality. More research is needed, especially in low-income and middle-income countries to describe the extent of limb loss.

Failure Modes in Orthopedic Oncologic Reconstructive Surgery: A Review of Imaging Findings and Failure Rates

Limb salvage surgeries utilizing endoprostheses and allografts are performed for a variety of oncologic conditions. These reconstructions can fail and require revision for many reasons, which are outlined and classified into mechanical failures (soft tissue failures, aseptic loosening, structural failure), non-mechanical failures (infection, tumor progression), and pediatric failures (physeal arrest, growth dysplasia). Distinct radiologic and clinical findings define specific failure subtypes but are sparsely illustrated in the radiology literature. Specifically, an understanding of the organizational structure of the failure modes can direct radiologists' search for post-reconstruction complications, enhance an appreciation of their prognostic significance, and facilitate research by standardizing the language and conceptual framework around outcomes. The purpose of this review is to highlight the key radiologic findings and imaging studies of each failure mode in orthopedic oncologic reconstructive surgery in the context of risk factors, failure rates, prognosis and survival statistics, and clinical decision-making regarding chemotherapy, radiation, and revision surgery.

A Two-Step Approach to the Surgical Treatment of Soft-Tissue Sarcomas

Background: Nowadays, limb-sparing procedures are the gold standard in the treatment of soft-tissue sarcomas of the limbs. Wide tumor resection with appropriate oncological margins, reconstruction, and stabilization of the involved bone and joint and restoration of the soft tissue lost are essential in order to obtain good clinical and functional outcomes. Tumor excision and soft-tissue reconstruction performed in one-step surgery is chosen by many centers as the preferred approach; however, according to our experience in some selected patients, two-step surgery performed using a dermal regeneration template first and then a margin revision, taking into account the definitive results of the anatomopathological exam conducted over the surgical specimen from the previous surgery, associated with definitive reconstruction surgery over a healthy bed of granulated tissue, showed many potential benefits. Methods: A retrospective observational study was conducted on thirteen patients who underwent a two-step reconstruction procedure using dermal substitution after soft-tissue sarcoma excision. Results: Clinically, the enrolled patients achieved excellent contour and cosmesis of their surgical wounds, with a mean VSS value of 3.07. During the follow-up period, no local recurrences were observed in any patient. Conclusions: Two-step surgery represents the most suitable solution to allow surgical radicality with minimal recurrency and adequate soft-tissue reconstruction, avoiding the possibility of wasting autologous tissue. Our patients generally embraced this approach and the management that followed.

Virtual reality-based surgical planning simulator for tumorous resection in FreeForm Modeling: an illustrative case of clinical teaching

The importance of virtual reality (VR) has been emphasized by many medical studies, yet it has been relatively under-applied to surgical operation. This study characterized how VR has been applied in clinical education and evaluated its tutorial utility by designing a surgical model of tumorous resection as a simulator for preoperative planning and medical tutorial. A 36-year-old male patient with a femoral tumor who was admitted to the Affiliated Jiangmen Traditional Chinese Medicine Hospital was randomly selected and scanned by computed tomography (CT). The data in digital imaging and communications in medicine (*.DICOM) format were imported into Mimics to reconstruct a femoral model, and were generated to the format of *.stl executing in the computer-aided design (CAD) software SenSable FreeForm Modeling (SFM). A bony tumor was simulated by adding clay to the femur, the procedure of tumorous resection was virtually performed with a toolkit called Phantom, and its bony defect was filled with virtual cement. A 3D workspace was created to enable the individual multimodality manipulation, and a virtual operation of tumorous excision was successfully carried out with indefinitely repeated running. The precise delineation of surgical margins was shown to be achieved with expert proficiency and inexperienced hands among 43 of 50 participants. This simulative educator presented an imitation of high definition, those trained by VR models achieved a higher success rate of 86% than the rate of 74% achieved by those trained by conventional methods. This tumorous resection was repeatably handled by SFM, including the establishment of surgical strategy, whereby participants felt that respondent force feedback was beneficial to surgical teaching programs, enabling engagement of learning experiences by immersive events which mimic real-world circumstances to reinforce didactic and clinical concepts.

Global Research Trends in Limb Salvage Surgery for Osteosarcoma: Findings from a Bibliometric and Visualized Analysis over 15 Years

Background

Limb salvage surgery in osteosarcoma requires a multidisciplinary team of experts, due to which research interest has remained limited globally. This article analyzes research trends over 15 years from 2007 to 2022.

Materials and Methods

Publications on limb salvage surgery in osteosarcoma were retrieved using the Web of Science. Bibliometric analysis of the publication metadata was done using R software. VOS viewer software was used to analyze the bibliographic coupling, co-citation, co-authorship, and co-occurrence to report the current trends in global research on limb salvage surgery in osteosarcoma.

Results

A total of 693 articles were retrieved. On applying the inclusion and exclusion criteria, a publication metadata of 276 articles was analyzed using the methodology mentioned. Annual scientific production on the subject has shown a steady rising trend globally. China has the highest number of publications on the topic; however, the USA has the highest citations globally. The Journal "Clinical Orthopedics and Related Research" remains the pioneer in the topic with the highest number of publications and H index among all journals. Most of the research interest is generated in the developed countries of the USA, Europe, and China. Keyword analysis suggested 4 clusters of surgical reconstruction, Survival, Chemotherapy, and general management related. Newer keywords such as biological reconstructions, allograft, metastases, cell, and chemotherapy suggest future research topics in the field.

Conclusion

Research interest in limb salvage surgery in osteosarcoma continues to grow with the introduction of concepts such as biological reconstructions and allografts. However, for more inclusive research on the topic, research interest must also be encouraged in underdeveloped and developing countries.

Successful megaprosthesis in a nearly amputated lower extremity after crush injury: A case report and literature review

Crush injury is one of the most challenging decisions for a surgeon to decide whether to proceed with an amputation or salvage a limb. We presented a 24-year-old man who complained of having suffered a crushed thigh 12 h before admission to the hospital. The patient was driving a truck and hit the iron bridge barrier, which penetrated his left thigh. The patient's left foot was cold, pallid, and pulseless, with a MESS score of 11. The femur x-ray showed a displaced fracture of the left femur associated with a 15 cm bone defect. The patient was diagnosed with a crush injury on the left femur with vascular compromise. We performed a proximal femoral megaprosthesis for a crush injury on the lower extremity, After the sixth year's follow-up, it shows a good outcome and increased quality of life for this patient. In addition, there was an improvement in the Harris Hip Score and EQ5D score. Megaprosthesis used to treat a crush injury revealed good functional outcomes despite the MESS score of 11. A multi-professional approach to the patient is essential for decision-making regarding limb salvage rather than the use of a score.

Understanding Gangrene in the Context of Peripheral Vascular Disease: Prevalence, Etiology, and Considerations for Amputation-Level Determination

Gangrene is a grave complication of peripheral vascular disease (PVD), characterised by tissue necrosis due to inadequate blood supply. This review article comprehensively explores gangrene in PVD, encompassing its prevalence, aetiology, clinical presentation, diagnostic modalities, management strategies, prognosis, and future directions. Key factors influencing outcomes, including the timeliness of intervention and the choice between limb salvage and amputation, are identified. Moreover, this review underscores the importance of early detection and multidisciplinary care, emphasising the significance of patient-centred approaches. It also calls for increased awareness, continued research, and innovative solutions to improve the lives of individuals grappling with gangrene in the context of PVD.

Lower limb amputation rehabilitation status in India: A review

Rehabilitation of lower limb amputation in developing countries is quite challenging. Though there are basic to highly advanced prostheses available in India, the set-up is still facing difficulties in developing countries. Prosthetic management is difficult due to lack of availability of prostheses and reduced affordability among low income populations. In this review we highlighted the lower limb amputation and prosthetic rehabilitation status in India. Currently, India is advancing well in the rehabilitation field, but further studies are required to provide more evidence and recommendation.

Outcomes of Surgical Reconstruction Using Custom 3D-Printed Porous Titanium Implants for Critical-Sized Bone Defects of the Foot and Ankle

BACKGROUND

Treating critically sized defects (CSDs) of bone remains a significant challenge in foot and ankle surgery. Custom 3D-printed implants are being offered to a small but growing subset of patients as a salvage procedure in lieu of traditional alternates such as structural allografts after the patient has failed prior procedures. The long-term outcomes of 3D-printed implants are still unknown and understudied because of the limited number of cases and short follow-up durations. The purpose of this study was to evaluate the outcomes of patients who received custom 3D-printed implants to treat CSDs of the foot and ankle in an attempt to aid surgeons in selecting appropriate surgical candidates.

METHODS

This was a retrospective study to assess surgical outcomes of patients who underwent implantation of a custom 3D-printed implant made with medical-grade titanium alloy powder (Ti-6Al-4V) to treat CSDs of the foot and ankle between June 1, 2014, and September 30, 2019. All patients had failed previous nonoperative or operative management before proceeding with treatment with a custom 3D-printed implant. Univariate and multivariate odds ratios (ORs) of a secondary surgery and implant removal were calculated for perioperative variables.

RESULTS

There were 39 cases of patients who received a custom 3D-printed implant with at least 1 year of follow-up. The mean follow-up time was 27.0 (12-74) months. Thirteen of 39 cases (33.3%) required a secondary surgery and 10 of 39 (25.6%) required removal of the implant because of septic nonunion (6/10) or aseptic nonunion (4/10). The mean time to secondary surgery was 10 months (1-22). Multivariate logistic regression revealed that patients with neuropathy were more likely to require a secondary surgery with an OR of 5.76 (P = .03).

CONCLUSION

This study demonstrated that 74% of patients who received a custom 3D-printed implant for CSDs did not require as subsequent surgery (minimum of 1-year follow-up). Neuropathy was significantly associated with the need for a secondary surgery. This is the largest series to date demonstrating the efficacy of 3D-printed custom titanium implants. As the number of cases using patient-specific 3D-printed titanium implant increases, larger cohorts of patients should be studied to identify other high-risk groups and possible interventions to improve surgical outcomes.

LEVEL OF EVIDENCE

The mangled extremity: assessment, decision making and outcomes

The management of the mangled extremity continues to pose a significant challenge for ortho- paedic trauma surgeons. This article provides a comprehensive, up-to-date literature review on the assessment of complex limb injuries, and the variables that affect decision-making and outcomes in both limb salvage and amputation. Initial assessment involves using a systematic approach, saving life before limb, with early involvement of the relevant surgical specialities and multidisciplinary team. The decision to attempt limb salvage or perform amputation can be extremely difficult. Scoring systems can be used as a guide but should not be wholly relied upon; instead more emphasis should be placed on the surgeon's experience, extent of soft tissue damage, and patient factors and wishes. Outcomes following amputation versus limb salvage are comparable, with some studies suggesting amputation may be favourable. It is important to advise patients and families on what treatment is in their best interest so they can make an informed decision, and this must utilise a multidisciplinary approach.

American Brachytherapy Society (ABS) consensus statement for soft-tissue sarcoma brachytherapy

PURPOSE

Growing data supports the role of radiation therapy in the treatment of soft tissue sarcoma (STS). Brachytherapy has been used for decades in the management of STS and can be utilized as monotherapy or as a boost to external beam radiation. We present updated guidelines from the American Brachytherapy Society regarding the utilization of brachytherapy in the management of STS.

METHODS AND MATERIALS

Members of the American Brachytherapy Society with expertise in STS and STS brachytherapy created an updated clinical practice guideline including step-by-step details for performing STS brachytherapy based on a literature review and clinical experience.

RESULTS

Brachytherapy monotherapy should be considered for lower-recurrence risk patients or after a local recurrence following previous external beam radiation; a brachytherapy boost can be considered in higher-risk patents meeting implant criteria. Multiple dose/fractionation regimens are available, with determination based on tumor location and treatment intent. Techniques to limit wound complications are based on the type of wound closure; wound complication can be mitigated with a delay in the start of brachytherapy with immediate wound closure or by utilizing a staged reconstruction technique, which allows an earlier treatment start with a delayed wound closure.

CONCLUSIONS

These updated guidelines provide clinicians with data on indications for STS brachytherapy as well as guidelines on how to perform and deliver high quality STS brachytherapy safely with minimal toxicity.

Heel Pad Reconstruction With Medial Plantar Flap

The heel of the foot is covered by highly specialized thick, glabrous skin containing fibroadipose tissue with numerous fibrous septae traversing the subcutaneous tissue, which acts as a shock-absorbent and prevents shearing of the skin. The loss of heel pad would cause interruption of the propelling function of the foot during walking. Therefore, heel pad reconstruction is an important procedure for wound closure in the acute phase and also functional reconstruction in delayed cases. We report a case of heel pad deformity in a patient who presented to us with left heel pain and inability to fully bear weight, which has caused her walking difficulty, following a road traffic accident. She sustained a degloving injury of the left foot and an open fracture of left calcaneum with ruptured Tendon Achilles in which the wound was initially addressed with failed reverse sural flap and the wound was allowed to heal by secondary intention. Delayed heel reconstruction was carried out with a propeller medial plantar flap and split skin graft. Postoperatively, the patient had improved functional and esthetic outcome.

Skin Graft Techniques

Management of extensive lower extremity soft tissue and skin loss can be a very difficult to achieve by any surgeon. There can be several associated comorbidities that need to be considered and addressed with these patients. The approach is multifactorial and requires commitment from both the surgeon as well as the patient. There are several protocols that have been formulated throughout the literature addressing soft tissue and skin coverage of the limbs. This article provides a review of the literature and describes the evaluation, harvesting, transplantation, and management of skin grafting techniques to the lower extremities.

The role of plastic and reconstructive surgeon in trauma care: Perspectives from a Level 1 trauma centre in India

Background

As the morbidity and mortality due to trauma are ever increasing, there is proportionally growing need of trauma care facilities across the country. In the context of expanding designated trauma care facilities, the role of plastic and reconstructive surgeon needs to be analysed and defined at least at a Level 1 trauma centre.

Materials and Methods

We included the patients who were operated under the department of plastic, reconstructive & burns surgery at a Level 1 urban trauma centre between January 2016 and December 2017. We analysed the demographic data and categorised operative data according to anatomical areas and interacting specialties.

Results

A total of 1539 procedures were performed under the division of plastic reconstructive and burn surgery. Amongst them, 81% were male, and 19% were female. Mean age was 27.3 years (range: 3-90 years). The anatomical locations treated were upper limb (49%), lower limb (35%), head and neck (8%) and trunk (8%). Interdepartmental cases were 600 and majority of them were in collaboration with orthopaedics (n = 298), general surgery (n = 163), neurosurgery (79) and maxillofacial surgery (60).

Conclusion

There is a significant role of plastic surgeon at a Level 1 trauma centre in India. The plastic surgeon's interventions are limb saving and sometimes lifesaving, many at times morbidity of post-traumatic sequelae are either prevented or treated. Along with other core specialties involved in the management of trauma, plastic surgeons play an integral role in a Level 1 trauma centre. The policymakers should take note to augment the number of plastic surgeons at a Level 1 apex trauma centre on par with other specialties, as the workload is heavy and is steadily on an increasing trend.

Lymph node transfer for refractory infectious sites caused by trauma

OBJECTIVE

In this report, we placed focus on the immunological function of lymph nodes and performed lymph node transfer via a free flap to a site of refractory infection.

CASE AND RESULTS

Case 1 describes a 34-year-old male suffering from compound fractures with severe crush injuries and burns in the right ankle joint. A 20 × 15 cm skin defect was observed around the right malleolus medialis, along with denuded tendons with bacterial infection. After conservative treatment, we transferred a lymph-node-containing free superficial circumflex iliac artery perforator flap to the region, with minimum debridement. No recurrence of wound infection appeared. Case 2 describes a 73-year-old male patient suffering from extensive contused wound in the right crus. Despite conservative treatment, the tibia gradually became denuded with computed tomography and magnetic resonance imaging revealing degeneration of the tibial cortex. We performed a free superficial circumflex iliac artery perforator flap containing lymph nodes to the chronic infection area. The wound area healed successfully.

CONCLUSION

In conclusion, lymph node transfer has a potential of treatment infection sites.

Massive segmental bone loss due to pantibial osteomyelitis in children reconstructed by medial fibular transport with Ilizarov frame

Objectives

Vascularized or non-vascularized fibula transport is a novel procedure for limb salvage but has been associated with high failure rates and complications. Ipsilateral medial fibular transport (IMFT) using Ilizarov apparatus is a modification of the procedure to prevent complications and increase success rate. This article presents the largest series of limb salvage for massive tibial bone loss in children due to pan-osteomyelitis by IMFT with Ilizarov apparatus.

Methods

A case series of 12 patients with a mean age of 12 (6-18) years is described. At the first stage of surgery, the excision of all dead bone was performed, and Ilizarov without traction apparatus was applied. In second stage, ipsilateral fibula is gradually transferred to tibial defect with the help of ilizarov olive wires. In the third stage, the freshening of docking sites of fibula to tibia was performed. The minimum follow up was of two years.

Results

Hypertrophy of the transported fibula accompanied by full weight bearing and satisfactory joint motion occurred in all patients. Removal of sequestrated bone resulted in control of infection in 27.17 ± 7.76 days. Fibular transport took 16.58 ± 4.14 days. The length of tibial bone loss replaced by fibula was 9.50 ± 2.23 cm. The mean days required for union after freshening of the docking site was 76.58 ± 6.20 days.

Conclusions

Ilizarov frame for pan tibial osteomyelitis with bone excision and medial fibular transport works well for limb salvage in children.

Limb salvage with microvascular free fibula following primary bone sarcoma resection

Background:

Extremity sarcomas are challenging to manage. Total eradication of tumour has to be balanced with restoration of limb function to prevent mortality and morbidity. Disease-free survival with maximum limb function is the ultimate goal in these patients.

Materials and Methods:

We present a series of ten cases of extremity malignancies, where limb salvage was attempted with microvascular free fibula for limb reconstruction from the period of 2008 to 2015.

Results:

Of the ten cases in the study, there were two females and eight males. There were nine patients with lower limb malignancies and one patient with upper limb malignancy. There were four patients with Ewing's sarcoma of femur, five patients with osteosarcoma of femur and one patient with chondrosarcoma of the humerus. The follow-up period ranged from 1.2 to 6.2 years with mean follow-up of 3.1 years. There were two deaths during follow-up, both were due to distant metastasis. The assessment of the function was done on the basis of Musculoskeletal Tumour Society functional score. Maximum score was 30 and minimum score was 24, the average score being 26. Of the eight surviving patients, three patients had full weightbearing, four patients had partial weightbearing at end of 2 years and one patient of upper limb reconstruction had complete upper limb function. None of the patients had to undergo limb amputation.

Conclusion:

Limb salvage with vascularised fibula graft offers good functional outcome along with good disease-free survival rates.

Staged reconstruction brachytherapy has lower overall cost in recurrent soft-tissue sarcoma

Purpose

Adjuvant brachytherapy (AB) with immediate (IR) and staged reconstruction (SR) are distinct treatment modalities available for patients with recurrent soft tissue sarcoma (STS). Although SR may offer local control and toxicity benefit, it requires additional upfront procedures, and there is no evidence that it improves overall survival. With the importance of value-based care, our goal is to identify which technique is more cost effective.

Material and methods

A retrospective review of 22 patients with recurrent extremity STS treated with resection followed by AB alone. Hospital charges were used to compare the cost between SR and IR at the time of initial treatment, at 6-month intervals following surgery, and cumulative cost comparisons at 18 months.

Results

Median follow-up was 31 months. Staged reconstruction (n = 12) was associated with an 18-month local control benefit (85% vs. 42%, p = 0.034), compared to IR (n = 10). Staged reconstruction had a longer hospital stay during initial treatment (10 vs. 3 days, p = 0.002), but at 18 months, the total hospital stay was no longer different (11 vs. 11 days). Initially, there was no difference in the cost of SR and IR. With longer follow-up, cost eventually favored SR, which was attributed primarily to the costs associated with local failure (LF). On multivariate analysis, cost of initial treatment was associated with length of hospital stay (~$4.5K per hospital day, p < 0.001), and at 18 months, the cumulative cost was ~175K lower with SR (p = 0.005) and $58K higher with LF (p = 0.02).

Conclusions

In recurrent STS, SR has a longer initial hospital stay when compared to IR. At 18 months, SR had lower rates of LF, translating to lower total costs for the patient. SR is the more cost-effective brachytherapy approach in the treatment of STS, and should be considered as healthcare transitions into value-based medicine.

Propeller Flap for Complex Distal Leg Reconstruction: A Versatile Alternative when Reverse Sural Artery Flap is Not Feasible

Reverse sural artery fasciocutaneous flap has become a workhorse for the reconstruction of distal leg soft tissue defects. When its use is not feasible, perforator-based propeller flap offers a better, easier, faster, and cheaper alternative to free flap. We present our experience with two men both aged 34 years who sustained Gustilo 3B injuries from gunshot. The donor area for reversed sural artery flap was involved in the injuries. They had early debridement, external fixation, and wound coverage with perforator-based propeller flaps. The donor sites were covered with skin graft. All flaps survived. There were minor wound edge ulcers due to the pressure of positioning that did not affect flap survival and the ulcers healed with conservative management. Perforator-based propeller flap is a versatile armamentarium for reconstruction of soft tissue defects of the distal leg in resource-constrained settings, especially when the donor area for a reverse flow sural flap artery is involved in the injury.

Flap decisions and options in soft tissue coverage of the lower limb

THE LOWER EXTREMITIES OF THE HUMAN BODY ARE MORE COMMONLY KNOWN AS THE HUMAN LEGS, INCORPORATING: the foot, the lower or anatomical leg, the thigh and the hip or gluteal region. The human lower limb plays a simpler role than that of the upper limb. Whereas the arm allows interaction of the surrounding environment, the legs' primary goals are support and to allow upright ambulation. Essentially, this means that reconstruction of the leg is less complex than that required in restoring functionality of the upper limb. In terms of reconstruction, the primary goals are based on the preservation of life and limb, and the restoration of form and function. This paper aims to review current and past thoughts on reconstruction of the lower limb, discussing in particular the options in terms of soft tissue coverage. This paper does not aim to review the emergency management of open fractures, or the therapy alternatives to chronic wounds or malignancies of the lower limb, but purely assess the requirements that should be reviewed on reconstructing a defect of the lower limb. A summary of flap options are considered, with literature support, in regard to donor and recipient region, particularly as flap coverage is regarded as the cornerstone of soft tissue coverage of the lower limb.
