ABSTRACT

Abstract Objective To evaluate the survival time, the failure rate and its causes, and the functional results of cemented endoprostheses, with a polyethylene body, used after resection of primary bone tumors of the distal femur. Methods A retrospective study including 93 primary and 77 review procedures performed between 1987 and 2014. Survival was obtained by the Kaplan Meyer analysis, and the risk factors for implant failure were assessed through the Cox proportional risk model. The causes of endoprosthesis failure were classified according to Henderson et al. into five types: soft-tissue failure, aseptic loosening, structural fracture, infection, and tumor recurrence. The functional evaluation was performed using the functional classification system of the Musculoskeletal Tumor Society (MSTS) of bone sarcomas of the lower extremity, Brazilian version (MSTS-BR). Results Osteosarcoma was the most common diagnosis; 64.5% of the patients were younger than 20 years of age; the mean follow-up was of 124.3 months. The failure rate of the primary implant was of 54.8%, and the mean survival was of 123 months. The estimated survival of the primary implant was of 63.6%, 43.5%, 24.1%, and 14.5% in 5, 10, 15, and 20 years respectively. The most common cause of failure was type 2 (37.3%). Age ≤ 26 years and right side were risk factors for failure. The mean MSTS-BR score was of 20.7 (range: 14 to 27). Conclusion The results obtained for the failure rate and survival of the implant are in accordance with those of the literature, so the procedure herein studied is adequate and yields satisfactory functional results, even in the long term.


Resumo Objetivo Avaliar o tempo de sobrevida, a taxa de falha e suas causas, e os resultados funcionais de endopróteses cimentadas, com corpo em polietileno, empregadas após ressecção de tumores ósseos primários do fêmur distal. Métodos Estudo retrospectivo, que incluiu 93 procedimentos primários e 77 de revisão, realizados entre 1987 e 2014. A sobrevida foi obtida pela análise de Kaplan Meyer, e os fatores de risco para falha do implante foram avaliados por meio do modelo de riscos proporcionais de Cox. As causas de falha da endoprótese foram classificadas segundo Henderson et al. em cinco tipos: falha de partes moles, soltura asséptica, fratura estrutural, infecção e recorrência do tumor. A avaliação funcional foi realizada por meio do sistema de classificação funcional da Musculoskeletal Tumor Society (MSTS) para sarcomas ósseos da extremidade inferior, versão brasileira (MSTS-BR). Resultados Osteossarcoma foi o diagnóstico mais comum; 64,5% dos pacientes tinham menos de 20 anos; e o seguimento médio foi de 124,3 meses. A taxa de falha do implante primário foi de 54,8%, e a sobrevida média foi 123 meses. A estimativa de sobrevida do implante primário foi de 63,6%, 43,5%, 24,1%, 14,5% em 5, 10, 15 e 20 anos, respectivamente. A causa de falha mais comum foi a do tipo 2 (37,3%). Idade ≤ 26 anos e lado direito foram fatores de risco para falha. A pontuação média no MSTS-BR foi de 20,7 (variação: 14 a 27). Conclusão Os resultados obtidos para a taxa de falha e o tempo de sobrevida do implante estão de acordo com os da literatura, de forma que o procedimento estudado é adequado e apresenta resultados funcionais satisfatórios, inclusive em longo prazo.

ABSTRACT

INTRODUCTION@#Percutaneous transluminal angioplasty (PTA) is commonly used to treat patients with chronic limb-threatening ischaemia (CLTI). This study aimed to examine the mortality and functional outcomes of patients with CLTI who predominantly had diabetes mellitus in a multi-ethnic Asian population in Singapore.@*METHODS@#Patients with CLTI who underwent PTA between January 2015 and March 2017 at the Vascular Unit at Singapore General Hospital, Singapore, were studied. Primary outcome measures were 30-day unplanned readmission, two-year major lower extremity amputation (LEA), mortality rates, and ambulation status at one, six and 12 months.@*RESULTS@#A total of 221 procedures were performed on 207 patients, of whom 184 (88.9%) were diabetics. The one-, six- and 12-month mortality rate was 7.7%, 16.4% and 21.7%, respectively. The two-year LEA rate was 30.0%. At six and 12 months, only 96 (46.4%) and 93 (44.9%) patients were ambulant, respectively. Multivariate analysis revealed that preoperative ambulatory status, haemoglobin, Wound Ischaemia and foot Infection (WIfI) score, and end-stage renal failure (ESRF) were independent predictors of one-year ambulatory status. Predictors of mortality at one, six and 12 months were ESRF, preoperative albumin level, impaired functional status and employment status.@*CONCLUSION@#PTA for CLTI was associated with low one-year mortality and two-year LEA rates but did not significantly improve ambulation status. ESRF and hypoalbuminaemia were independent predictors of mortality. ESRF/CKD and WIfI score were independent predictors of loss of ambulation at six months and one year. We need better risk stratification for patients with CLTI to decide between initial revascularisation and an immediate LEA policy.

ABSTRACT

Resumo Pacientes portadores de doença arterial obstrutiva periférica com isquemia crítica do membro associada a infecção de prótese vascular apresentam elevadas taxas morbimortalidade e alto risco de perda do membro. Apresentamos o caso de um paciente masculino de 76 anos com isquemia crítica do membro inferior esquerdo associada a infecção de prótese vascular femoropoplítea. Utilizamos abordagem híbrida para o tratamento com acesso cirúrgico das regiões inguinais e poplíteas, sendo a prótese vascular utilizada como acesso endovascular para recanalização direta da artéria femoral superficial devido a obstrução longa e extensa calcificação, que impediram as tentativas iniciais de tratamento endovascular. Após a recanalização endovascular, a prótese infectada foi retirada. O avanço das técnicas e materiais endovasculares em associação com a cirurgia aberta permitem novas soluções para pacientes quando os procedimentos habituais falham.


Abstract Patients with severe arterial obstructive disease and critical limb ischemia associated with vascular graft infection have elevated morbidity and mortality rates and are at high risk of limb loss. We present the case of a 76-year-old male patient with left lower limb critical ischemia and a femoropopliteal vascular graft infection. We used a hybrid treatment approach with an open surgical approach to the inguinal and popliteal regions and used the vascular prosthesis as endovascular access for direct recanalization of the superficial femoral artery, because the long occlusion and extensive calcification had frustrated initial attempts at endovascular treatment. After endovascular recanalization, the infected graft was removed. Used in conjunction with open surgery, advances in endovascular techniques and materials offer new solutions for patients when usual procedures fail.

ABSTRACT

RESUMO Contexto A doença arterial obstrutiva periférica apresenta alta prevalência, sendo associada a elevado risco de eventos cardiovasculares. A intervenção cirúrgica ou endovascular faz-se necessária na isquemia crítica do membro. Objetivos Avaliar a distribuição de realização de revascularizações abertas e endovasculares nas diferentes regiões do Brasil, analisando os custos para o sistema de saúde e a mortalidade relacionada a esses procedimentos. Métodos Foi realizado um estudo epidemiológico observacional transversal descritivo para avaliar as cirurgias abertas e endovasculares realizadas no sistema público de saúde do Brasil entre 2010 e 2020. Os dados foram coletados através do Departamento de Informática do SUS (Datasus). Resultados No período analisado, foram registradas 83.218 internações para realização de cirurgias abertas e endovasculares, com um custo total de R$ 333.989.523,17. Houve predominância das internações para os procedimentos percutâneos (56.132) em relação aos cirúrgicos convencionais (27.086). As Regiões Sudeste e Sul concentraram a maior parte do total de procedimentos realizados no país (83%), enquanto a Região Norte foi a que apresentou a menor taxa de internação. Observou-se uma tendência decrescente para os procedimentos abertos, e uma tendência crescente para os endovasculares. A média de permanência hospitalar foi menor nos procedimentos endovasculares (5,3 dias) em relação aos abertos (10,2 dias). Além disso, notou-se uma maior taxa de mortalidade hospitalar relacionada à revascularização aberta em relação à endovascular (5,24% versus 1,56%). Conclusões As técnicas endovasculares consistiram em uma abordagem dominante no tratamento cirúrgico da isquemia crítica, apresentando menor taxa de mortalidade hospitalar e menor tempo de internação quando comparada às cirurgias abertas.


ABSTRACT Background Peripheral artery disease (PAD) has high prevalence and is associated with high risk of cardiovascular events. Surgical or endovascular intervention is necessary in chronic limb-threatening ischemia. Objectives To evaluate the distribution of open and endovascular revascularizations in different regions of Brazil, analyzing the health system costs and mortality related to these procedures. Methods A descriptive, cross-sectional, observational, epidemiological study was carried out to evaluate open and endovascular surgeries performed on the SUS public healthcare system in Brazil, from 2010 to 2020. Data were collected from the SUS Department of Informatics (Datasus). Results Over the period analyzed, 83,218 admissions for open and endovascular surgeries were registered, with a total cost of R$ 333,989,523.17. There were more hospital admissions for percutaneous procedures (56,132) than for conventional surgery (27,086). Most of the procedures (83%) were performed in the country's Southeast and South regions, while the North region had the lowest number of procedures. Over the period evaluated, there was a decreasing trend for open procedures and an increasing trend for endovascular procedures. The average hospital stay was shorter for endovascular procedures (5.3 days) than for open surgery (10.2 days). The analysis of mortality related to these procedures revealed a higher rate of in-hospital mortality associated with open revascularization than with endovascular (5.24% vs. 1.56%). Conclusions Endovascular techniques constituted the primary approach for revascularization treatment in critical limb-threatening ischemia, with a lower in-hospital mortality rate and shorter hospital stay when compared to open surgeries.

ABSTRACT

Shark attacks are rare unique pathological processes. Some of them represent devastating injuries with a high morbidity and significant mortality. Related published articles are limited. The increased human interaction within the environment of sharks is the cause of rising incidence of such attacks. This study reported a case of level 4 shark injuries (shark-induced trauma scale) in a 33-year-old male patient, who presented with an extensive injury of the right lower limb with the characteristic features of shark bite. At admission the patient was in a state of shock with profuse bleeding that was controlled by tourniquet. The patient was resuscitated according to the advanced trauma life support. Clinical examination showed hard signs of vascular injury with absent pedal pulse, associated neurological deficits and severance at the knee joint. Prompt vascular intervention after resuscitation was performed to manage the major vascular injuries, together with proper washout and debridement of all the necrotic tissues under strong antibiotic coverage to prevent infection. After that, the patient underwent sequenced plastic, orthopedic, and neurological interventions. Strict follow-up was conducted, which showed that the patient was saved and achieved a functioning limb. This study aims to highlight the management of level 4 shark injuries, which are considered serious and challenging with a high fatality rate and a great risk of amputation due to the associated major vascular injuries. Immediate well organized management plan is crucial. Prompt resuscitation and surgical intervention by a highly-skilled medical team are required to improve the chance of patient survival and limb salvage.

ABSTRACT

Abstract Since the coronavirus pandemic set in in Spain in March 2020, a noteworthy increase in the incidence of acute limb ischemia (ALI) has been observed. It has been recently discovered that SARS-CoV 2 may lead to ALI secondary to arterial thrombosis. Elevation of D-dimer (DD) in patients with coronavirus infection (COVID-19) indicates that a hypercoagulable state causes acute arterial thrombosis. A remarkably high DD elevation has been reported to be a poor prognosis factor in COVID-19. The ways in which SARS-CoV 2 results in arterial thrombosis may be multiple. On the other hand, surgical revascularization for ALI is associated with poor outcomes in COVID-19 patients, probably in relation to hypercoagulability. Here, we describe two ALI cases in patients who required urgent surgical treatment for limb salvage and were positive for the novel coronavirus infection (COVID 19).


Resumo Desde que a pandemia pelo novo coronavírus se estabeleceu na Espanha, em março de 2020, um aumento notável da incidência de isquemia aguda de membros foi observado. Recentemente, descobriu-se que o coronavírus 2 causador da síndrome respiratória aguda grave (SARS-CoV-2) pode ocasionar isquemia aguda de membros secundária à trombose arterial. A elevação do D-dímero em pacientes acometidos pela doença do novo coronavírus (COVID-19) indica o estado de hipercoagulabilidade como causa da trombose arterial aguda. Vale destacar que a alta elevação do D-dímero foi relatada como um fator de prognóstico reservado na COVID-19. Há diversas maneiras pelas quais o SARS-CoV-2 pode resultar em trombose arterial. Em pacientes com COVID-19, a revascularização cirúrgica para isquemia aguda de membros está associada a desfechos desfavoráveis, provavelmente relacionados a hipercoagulabilidade. Descrevemos dois casos de isquemia aguda de membros de pacientes que necessitaram de tratamento cirúrgico de urgência para salvamento de membro e que haviam testado positivo para COVID-19.

ABSTRACT

Background: Chronic limb ischemia can lead to high rates of limb loss and mortality. Open surgery is the gold standard for treatment of distal disease. Endovascular surgery should have less complications with similar outcomes. Aim: To report a cohort of patients with distal arterial disease treated with endovascular surgery at our institution. Material and Methods: Review of angioplasty records of patients undergoing distal lower extremity endovascular procedures between 2016 and 2019. Demographics, comorbidities, form of presentation, type of intervention, perioperative complications, and length of stay were analyzed. The primary outcomes were wound healing, reinterventions and freedom from major amputation. Secondary outcomes were overall survival and amputation-free survival. Results: Forty-eight limbs of 41 patients with a mean age 75 years (78% males) were treated. Ninety-three percent had hypertension, 88% diabetes, 30% chronic kidney disease. 73% presented with major wounds. Plain balloon and drug coated balloon angioplasties were carried out in 65 and 31% of procedures respectively, with no difference in results. In 46% of the cases, only chronic total occlusions were treated. Wound healing was achieved in 85% of procedures and 90% of patients were free from amputation at one year of follow up. Complications were observed in 18% of procedures, perioperative mortality was 2% and one-year survival was 76%. Conclusions: Endovascular therapy achieves high rates of wound healing and freedom from amputation with low perioperative mortality and moderate complication rates.

ABSTRACT

Resumo Contexto As oclusões arteriais agudas (OAA) de membros vêm crescendo paralelemente com a longevidade da população. Objetivos O objetivo deste estudo foi avaliar fatores de risco, salvamento de membros e sobrevida dos pacientes com OAA tratados em instituição universitária. Métodos Este é um estudo coorte retrospectivo de pacientes consecutivos. Os desfechos incluíram: sucesso técnico, sintomas, comorbidades, categoria Rutherford, artérias acometidas, complicações pós-operatórias, taxa de salvamento de membros em 30 dias e óbitos. Resultados Avaliou-se 105 prontuários, havendo predomínio do sexo masculino (65,7%) e idade entre 46 a 91 anos. As etiologias identificadas foram trombóticas (54,3%), embólicas (35,2%) e indefinidas (10,5%). Cerca de dois terços apresentavam-se nas Categorias II e III de Rutherford. Os sintomas associados encontrados foram dor (97,1%), esfriamento (89,5%), palidez (64,7%), parestesias (44,7%), paralisias (30,5%), anestesias (21,9%), edema (21,9%) e cianose (15,2%); e as comorbidades associadas observadas foram hipertensão (65,0%), tabagismo (59,0%), arritmias (26,6%), dislipidemias (24,0%) e diabetes (23,8%). O segmento femoral superficial-poplíteo-distal foi o mais acometido (80%). A tromboembolectomia com cateter Fogarty foi realizada em 73,3% dos casos (81,0% nas embolias, 71,9% nas tromboses e 54,5% nos indefinidos), sendo isoladamente em 41 pacientes (39,05%), nos quais ocorreram 11 reoclusões, 20 amputações e 14 óbitos. A reoclusão arterial foi mais frequente nas tromboses (12,9%; p = 0,054). Até 30 dias após tratamento, o óbito total foi de 14,6% e a amputação maior foi de 19,8%, sendo menos frequente na Classe I Rutherford (p = 0,0179). Conclusão O tratamento da OAA feito prioritariamente por meio de tromboembolectomia com cateter Fogarty, isolado e/ou associado, proporcionou taxas de amputação e complicações compatíveis com as apresentadas na literatura e progressivamente menores nas categorias Rutherford menos avançadas.


Abstract Background Acute arterial occlusions (AAO) in limbs have been increasing in parallel with population longevity. Objective To assess risk factors, limb salvage rates, and survival of patients with AAO treated at a University Hospital. Methods Retrospective cohort study of consecutive patients. Outcomes included: patency, symptoms, comorbidities, Rutherford category, arteries occluded, postoperative complications, and 30-day limb salvage and mortality rates. Results Medical records were evaluated from 105 patients, predominantly males (65.7%), with ages ranging from 46 to 91 years. Etiology: thrombotic (54.3%), embolic (35.2%), and undefined (10.5%). About 2/3 of the patients were assessed as Rutherford category II or III. Associated symptoms: pain (97.1%), coldness (89.5%), pallor (64.7%), sensory loss (44.7%), paralysis (30.5%), anesthesia (21.9%), edema (21.9%), and cyanosis (15.2%). Associated comorbidities: hypertension (65.0%), smoking (59.0%), arrhythmias (26.6%), dyslipidemia (24.0%), and diabetes (23.8%). The distal superficial femoral-popliteal segment was the most affected (80%). Thromboembolectomy with a Fogarty catheter was performed in 73.3% of cases (81.0% of embolic cases, 71.9% of thrombotic cases, and 54.5% of cases with undefined etiology) and was the only treatment used in 41 cases (39.05%), among which there were 11 reocclusion, 20 amputations, and 14 deaths. Arterial reocclusion was more frequent in thrombosis cases (12.9%, p = 0.054). Within 30 days of treatment, total mortality was 14.6%, and 19.8% of cases underwent major amputation, which was less frequent among Rutherford Class I patients (p = 0.0179). Conclusion Treatment of AAO was primarily performed by thromboembolectomy with a Fogarty catheter, either alone or in combination with other treatments, achieving amputation and complication rates compatible with the best results in the literature and were progressively lower in less advanced Rutherford categories.

ABSTRACT

Resumo A Society for Vascular Surgery propôs nova classificação para o membro inferior ameaçado, baseada nos três principais fatores influenciadores do risco de amputação do membro: ferida (Wound, W), isquemia (Ischemia, I) e infecção do pé (foot Infection, fI): a classificação WIfI. Esta abrange também os diabéticos, anteriormente excluídos do conceito de isquemia crítica do membro devido a seu quadro clínico complexo. O objetivo da classificação era fornecer estratificação de risco precisa e precoce ao paciente com membro inferior ameaçado; auxiliar no manejo clínico, permitindo comparar terapias alternativas; e predizer o risco de amputação em 1 ano e a necessidade de revascularização. O objetivo deste estudo é reunir os principais pontos abordados sobre a classificação WIfI no meio científico. A maior parte dos estudos de validação da classificação demonstram sua associação à predição de salvamento do membro, eventos de reintervenção, amputação e estenose, taxas de amputação maior e menor, sobrevida livre de amputação, e cicatrização de feridas.


Abstract The Society for Vascular Surgery has proposed a new classification system for the threatened lower limb, based on the three main factors that have an impact on limb amputation risk: Wound (W), Ischemia (I) and foot Infection ("fI") - the WIfI classification. The system also covers diabetic patients, previously excluded from the concept of critical limb ischemia because of their complex clinical condition. The classification's purpose is to provide accurate and early risk stratification for patients with threatened lower limbs; assisting with clinical management, enabling comparison of alternative therapies; and predicting risk of amputation at 1 year and the need for limb revascularization. The objective of this study is to collect together the main points about the WIfI classification that have been discussed in the scientific literature. Most of the studies conducted for validation of this classification system prove its association with factors related to limb salvage, such as amputation rates, amputation-free survival, prediction of reintervention, amputation, and stenosis (RAS) events, and wound healing.

ABSTRACT

Introdução: Uma das técnicas cirúrgicas utilizadas como uma alternativa à amputação no tratamento de sarcomas ósseos é a substituição do segmento acometido por endopróteses não convencionais. Embora a endoprótese melhore a qualidade de vida dos indivíduos existe uma necessidade de reabilitação intensiva para se obter melhores resultados funcionais. Objetivo: Realizar uma revisão de literatura sobre as intervenções fisioterapêuticas no pós-operatório de endoprótese não convencional de tíbia proximal, para o tratamento de sarcomas ósseos. Métodos: Revisão de literatura, direcionada a protocolos fisioterapêuticos na reabilitação de pacientes submetidos à cirurgia de preservação de membros de tíbia proximal. Resultados: Dentre os artigos estudados, três foram selecionados para comparação de protocolos fisioterapêuticos de tratamento no pós-operatório de cirurgia de preservação de membros de tíbia proximal. Conclusão: Concluiu-se que é necessário um maior incentivo no desenvolvimento de pesquisas relacionadas a protocolos de reabilitação fisioterapêutica no pós-operatório de LSS em tíbia proximal, para que sejam obtidas mais alternativas de tratamento que visam melhorar a qualidade de vida e sobrevida destes pacientes. (AU)


Introduction: One of the surgical treatment techniques used as an alternative to amputation is limb salvage surgery (LSS) with endoprothesis. Although the LSS can improve quality of life, causes a variety of functional deficiencies, and creates a need to integrate physical therapy rehabilitation into the team for LSS. Objective: To carry out a review on the physiotherapeutic interventions in the postoperative LSS in patients with proximal tibial osteosarcoma. Methods: Literature review, aimed at physiotherapeutic protocols in the rehabilitation of patients submitted to preservation surgery of limbs of proximal tibia. Results: Among the articles studied, three were selected for comparison of physiotherapeutic treatment protocols in the postoperative of preservation surgery of limbs of proximal tibia. Conclusion: We concluded that a greater incentive is needed in the development of research related to physiotherapeutic rehabilitation protocols in the LSS postoperative period in the proximal tibia, in order to obtain more treatment alternatives that aim to improve the quality of life and survival of these patients.

ABSTRACT

INTRODUCCIÓN: El trauma vascular es un evento de baja frecuencia, con alta morbimortalidad que afecta la población joven; requiere en general un manejo quirúrgico. Se asocia a complicaciones desde la reintervención quirúrgica hasta la amputación de la extremidad, influenciado por variables tanto asociadas al trauma como a la atención hospitalaria. OBJETIVO: Determinar los factores de riesgo relacionados con amputación, en pacientes con trauma arterial periférico (TAP), atendidos en un Hospital de III nivel Huila- Colombia entre 2014-2017. MATERIALES Y MÉTODOS: Estudio observacional, analítico de corte retrospectiva con pacientes mayores de 13 años con TAP. RESULTADOS: Se incluyeron 79 pacientes, con un 1,56% de las consultas en nuestro Servicio de Urgencia. 89% hombres, promedio de edad 28,5 años. La principal comorbilidad fue la farmacodependencia 8,8%. El MESS (mangled extremity severity) promedio fue de 5,27 puntos y un tiempo critico de isquemia de extremidad > a 6 horas en el 38%. El mayor compromiso fue de miembros superiores, secundario a heridas por arma cortopunzante. La lesión predominante fue la transección arterial. Las principales complicaciones posquirúrgicas fueron la trombosis del vaso (21,5%) y la amputación (13,9%). Factores de riesgo asociados a amputación fueron la edad > 20 años, estancia hospitalaria > 7 días, MESS > 7 puntos, que presentaran como complicación quirúrgica la trombosis arterial y que requirieran reintervención quirúrgica. CONCLUSIONES: El trauma arterial periférico es una patología con gran repercusión socioeconómica y secuelas funcionales. Es necesaria la atención oportuna con tratamiento de las variables relacionadas con mal pronóstico, con el fin de disminuir las tasas de morbimortalidad.


INTRODUCTION: Vascular trauma is a low frequency event, with high morbidity and mortality that affects the young population; In general, it requires surgical management. It is associated with complications from surgical reintervention to amputation of the limb, influenced by trauma associated variables such as hospital care. AIM: Determine risk factors related to amputation, in patients with peripheral arterial trauma (TAP), treated at a Hospital of III level Huila-Colombia between 2014-2017. MATERIALS AND METHOD: Observational, retrospective analytical study with patients older than 13 years with TAP. RESULTS: We included 79 patients with an incidence of 1.56%. 89% men, average age 28.5 years. The main comorbidity was 8.8% drug dependence. The MESS (Mangled extremity severity) average was of 5.27 points and a critical time of limb ischemia > to 6 hours in 38%. The greater commitment was of superior members, secondary to injuries by sharp weapon. The predominant lesion was arterial transection. The main postoperative complications were vessel thrombosis (21.5%) and amputation in 13.9%. Risk factors associated with amputation were determined by age > 20 years, hospital stay > 7 days, MESS > 7 points, and that they presented arterial thrombosis as a surgical complication and finally required surgical reoperation. CONCLUSIONS: Peripheral arterial trauma is a pathology with great socioeconomic impact and functional sequelae. It is necessary the timely attention with treatment of the variables related to poor prognosis, in order to decrease the morbidity and mortality rates.

ABSTRACT

PURPOSE: Tumor infiltration around the knee joint or skip metastasis, repeated infection sequelae after tumor prosthesis implantation, regional recurrence, and mechanical failure of the megaprosthesis might require combined distal femur and proximal tibia replacement (CFTR). Among the aforementioned situations, there are few reports on the indication, complications, and implant survival of CFTR in temporarily arthrodesed patients who had a massive bony defect on either side of the knee joint to control infection. MATERIALS AND METHODS: Thirty-four CFTR patients were reviewed retrospectively and 13 temporary arthrodesed cases switched to CFTR were extracted. All 13 cases had undergone a massive bony resection on either side of the knee joint and temporary arthrodesis state to control the repeated infection. This paper describes the diagnosis, tumor location, number of operations until CFTR, duration from the index operation to CFTR, survival of CFTR, complications, and Musculoskeletal Tumor Society (MSTS) score. RESULTS: According to Kaplan-Meier plot, the 5- and 10-year survival of CFTR was 69.0%±12.8%, 46.0%±20.7%, respectively. Six (46.2%) of the 13 cases had major complications. Three cases underwent removal of the prosthesis and were converted to arthrodesis due to infection. Two cases underwent partial change of the implant due to loosening and periprosthetic fracture. The remaining case with a deep infection was resolved after extensive debridement. At the final follow-up, the average MSTS score of 10 cases with CFTR was 24.6 (21–27). In contrast, the MSTS score of 3 arthrodesis cases with failed CFTR was 12.3 (12–13). The average range of motion of the 10 CFTR cases was 67° (0°–100°). The mean extension lag of 10 cases was 48° (20°–80°). CONCLUSION: Although the complication rates is substantial, conversion of an arthrodesed knee to a mobile joint using CFTR in a patient who had a massive bony defect on either side of the knee joint to control infection should be considered. The patient's functional outcome was different from the arthrodesed one. For successful conversion to a mobile joint, thorough the eradication of scar tissue and creating sufficient space for the tumor prosthesis to flex the knee joint up to 60° to 70° without soft tissue tension.

ABSTRACT

Peripheral arterial disease is one part of systematic atherosclerosis, becoming a heavy burden of human health. Patients in end stage of peripheral arterial disease manifest critical limb ischemia with severe rest pain and refractory ulcer. Surgical revascularization is the optimal option for patients with critical limb ischemia to avoid major amputation and improve quality of life. However, some of them contraindicate surgical revascularizations owing to coexisting morbidities. Spinal cord stimulation is reported to be effective and minimally invasive in pain relief and limb salvage for patients with limb ischemia. Here, we reported one case with chronic critical limb ischemia and gangrene of foot who underwent spinal cord stimulation, which was, as we knew, the first case in China. He was diagnosed with Burger disease and accompanied with history of stroke, chronic obstructive pulmonary disease and Castleman's disease. It showed totally occlusive lesions of external iliac and femoropopliteal artery and no outflows below the knee in the computed tomography angiography. Given the complexity of lesions and weakness of the patient, spinal cord stimulation was indicated for control of rest pain and limb salvage. As specified, we implanted the temporary neurostimulator as the first step. After 2 weeks from temporary neurostimulator implantation, the patient achieved significant relief in intensity of pain, and acquired 20% improvement of transcutaneous oxygen pressure. The satisfactory results indicated probable effectiveness of spinal cord stimulation, thus we performed the permanent neurostimulator implantation 1 month later. During 2 months of follow-up, the patients stabilized at Fountain III with pain relief with one kind of nonsteroidal anti-inflammatory drug. In our case, we confirmed the significant validity of spinal cord stimulation for pain control and consequent improvement of quality of life in non-reconstructable chronic critical limb ischemia. Furthermore, we reviewed that a number of published studies suggested that spinal cord stimulation be a reasonable option for patients with critical rest pain, especially who contraindicated surgical revascularization. The application of spinal cord stimulation in pain relief for non-reconstructable chronic critical limb ischemia was approved by related guidelines released by European Society of Cardiology and Trans-Atlantic Inter-Society Consensus. Further investigations are required for assessing the long-term outcome in limb salvage.

ABSTRACT

After diagnosis of peripheral artery disease in diabetic patients, revascularization can be considered in those who are not improved after guideline-directed medical therapy. Recently, more aggressive approaches with interventional treatment have been recommended. Before revascularization therapy, it is important to differentiate patients with claudication or critical limb ischemia, and the final goal and treatment modality of interventional treatments should be based on clinical diagnosis. For patients with claudication, the goal of revascularization is improvement of functional capacity or quality of life; however, in more severe forms of critical limb ischemia, the purpose of revascularization is limb salvage and ultimately saving patient's life. With improvement of vascular interventions, interventional treatment for peripheral artery disease is preferred, although surgical treatment might show better results than intervention in some cases.

ABSTRACT

PURPOSE: Mangled injury is defined as severe injury, including three or more tissues such as bones, nerves, vessels, muscles, and tendons in the upper or lower extremities. The choice of treatment results in different cosmetic and functional outcomes for mangled injury. In this study, we estimated patients' quality of life after treatment with the future intention of having patients make proper decisions at the time of injury. METHODS: Twenty patients were treated at Asan Medical Center from January, 2009 to November, 2011, and 11 patients were included who agreed with the questionnaire. We used 36-item short form health survey (SF-36) for estimating quality of life after treatments. RESULTS: Subjective satisfaction of cosmetic and functional aspects was higher in the reconstruction group than in the amputation group. However, in the estimation of specified satisfaction using SF-36, the amputation group was more satisfied than the reconstruction group. CONCLUSION: Among the many treatment considerations at the time of injury, expected cosmetic and functional outcomes were important parts determining the decision. In our study, the amputation group showed a better satisfaction level. This result could help patients make more appropriate decisions in the case of mangled injury.

ABSTRACT

Ameloblastoma in the tibia is rare. Limb reconstruction after tumor resection is challenging in terms of selection of the operative method. Here, we report a case of radical resection of an ameloblastoma in the mid-distal tibia combined with limb salvage using a three-dimensional (3D)-printed prosthesis replacement, with 1-year follow-up results. After receiving local institutional review board approval, a titanium alloy prosthesis was designed using a computer and manufactured with 3D-printing technology. During the operation, the stem of the prosthesis was inserted closely into the proximal tibial medullary cavity. Then, the metal ankle mortise and the talus were compacted closely. Radiographic results at 1-year follow up showed that the prosthesis was well placed, and no loosening was observed. The Musculoskeletal Tumor Society (MSTS) 93 functional score was 26 points, and the functional recovery percentage was 86.7%. Computer-assisted 3D-printing technology allowed for more volume and structural compatibility of the prosthesis, thereby ensuring a smooth operation and initial prosthetic stabilization. During the follow up, the presence of bone ingrowths on the porous surface of some segments of the prosthesis suggested good outcomes for long-term biological integration between the prosthesis and host bone.

ABSTRACT

PURPOSE: The clinical characteristics and results of femoropopliteal artery injury (FPAI) remain unclear. In this study, we evaluated the outcomes and risk factors of limb loss in patients treated for FPAI. MATERIALS AND METHODS: We retrospectively reviewed data from a database of patients who underwent revascularization for an FPAI at a single institution between January 2013 and December 2017. We reviewed and analyzed the characteristics, postoperative results, and factors that influence amputation rates. RESULTS: Twenty-four femoropopliteal arterial reconstructions in 24 patients were included in this study. Among the patients were 20 (83.3%) male with a first-quartile age of 28 years and a third-quartile age of 45 years (range, 15–68 years). The mean injury severity score (ISS) was 16 (range, 4–55), and 5 patients (20.8%) had ISSs of >20 points. The mean mangled extremity severity score (MESS) was 3.8 (range, 1–11), and 8 patients (33.3%) had MESSs of >5 points. In terms of arterial reconstruction methods, autogenous saphenous vein grafting, vein patching, and primary closure were performed in 9 patients (37.5%), 4 patients (16.7%), and 11 patients (45.8%), respectively. Despite arterial reconstruction, 5 patients (20.8%) underwent above-knee amputation. ISSs of >20, MESSs of >7, and orthopedic fixation were statistically significant factors associated with amputation. CONCLUSION: In cases of FPAI with ISSs of >20, MESSs of >7, and orthopedic fixation, amputations should be considered. We were also careful to attempt limb salvage in such cases.

ABSTRACT

Background: Extremity arterial injuries are an important cause of loss of life/limb after trauma. Early intervention is important for the good outcome. Objectives: The objective of this study is to review the pattern of presentation and study the factors that influences the outcome of extremity arterial injuries in our hospital. Patients and Methods: This is a retrospective study of all patients with injuries to the extremity arteries requiring surgical intervention from July 2007 to June 2015. Data obtained included biodata, ischemic time, arteries involved, surgical intervention, and outcomes and analyzed using SPSS version 22. Setting: Our hospital is the main referral hospital for vascular trauma serving four adjoining states in Nigeria and is linked to major cities by at least 3 Trunk-A federal roads. Subjects: The subjects are patients who were managed in our cardiovascular surgical unit for the study duration (July 2007­June 2015) who had extremity arterial injuries. Results: A total of 36 patients presenting with 40 arterial injuries in 37 limbs were studied. The mean age was 28.4 ± 10.3 years with male preponderance (88.9%). Gunshot injuries were the most common cause of arterial injuries (37.8%), followed by assault (27%). The mean time from injury to presentation for acute injuries was 20.4 h but 23 of the patients (63.8%) presented to the accident and emergency department within 12 h of injury. A limb salvage rate of 64.9% was achieved though ischemic times of ≥12 h were associated with poor outcomes. Conclusion: Prolonged ischemic time is associated with poor outcomes. Efforts should be put in place to reduce the limb ischemic times

ABSTRACT

Las úlceras del pie diabético son el principal factor de riesgo para las amputaciones no traumáticas en personas con diabetes. El éxito de la intervención requiere un completo entendimiento de la patogénesis y una implementación oportuna y estandarizada de un tratamiento efectivo. Es necesario un enfoque multidisciplinario para inicialmente controlar y tratar múltiples factores causantes de la ulceración severa del pie diabético. El desbridamiento, control de la infección y revascularización son pasos clave para la estabilización de la herida y su preparación para una reconstrucción exitosa. La microcirugía y supermicrocirugía permite proporcionar un tejido bien vascularizado para controlar la infección, un contorno adecuado para el calzado, durabilidad y anclaje sólido para resistir las fuerzas de cizallamiento durante la marcha. De esta manera, se puede lograr el salvataje de la extremidad, mejorando la calidad de vida y aumentando la sobrevida.


Diabetic foot ulcers are the main risk factor for non-traumatic amputations in people with diabetes. A succesful intervention requires a thorough understanding of the pathogenesis and a timely and standardized implementation of an effective treatment. A multidisciplinary approach is needed to initially control and treat multiple factors that cause severe diabetic foot ulceration. Debridement, infection control, and revascularization are key steps in wound stabilization and preparation for successful reconstruction. Microsurgery and supermicrosurgery provide a well-vascularized tissue to control infection, an adequate shoe contour, durability and solid anchorage to resist shearing forces during gait. In this way, the salvage of the limb can be achieved, improving the quality of life and increasing the survival rate.

ABSTRACT

ABSTRACT Peri-articular giant cell tumours present a unique challenge to the orthopaedic surgeon due to their locally aggressive nature. Native joint-preserving options confer less morbidity in comparison to radical excision and reconstruction; however, recurrence rates tend to be higher. The use of polymethyl methacryllate (PMMA) decreases the recurrence rate, but it has potentially devastating effects on the articular cartilage. To safeguard against this, the use of an insulating layer between the PMMA and the articular cartilage may be utilized with the goal of protecting the latter and is referred to as the Sandwich technique.


RESUMEN Los tumores de células gigantes periarticulares representan un desafío único al cirujano ortopédico debido a su naturaleza localmente agresiva. Las opciones de conservación de las articulaciones nativas confieren menos morbilidad en comparación con la supresión y reconstrucción radicales. Sin embargo, las tasas de recurrencia tienden a ser más altas. El uso de polimetilmetacrilato (PMMA) disminuye la tasa de recurrencia, pero tiene efectos potencialmente devastadores sobre el cartílago articular. Para protegerlo, el uso de una capa aislante entre el PMMA y el cartílago articular puede ser utilizarse con el objetivo de proteger este último, lo que se conoce como la técnica del sándwich.
