Clinical application of Flow-through bridge anterolateral thigh flap in repair of complex calf soft tissue defects / 中国修复重建外科杂志

OBJECTIVE@#To investigate the effectiveness of Flow-through bridge anterolateral thigh flap transplantation in the treatment of complex calf soft tissue defects.@*METHODS@#The clinical data of the patients with complicated calf soft tissue defects, who were treated with Flow-through bridge anterolateral thigh flap (study group, 23 cases) or bridge anterolateral thigh flap (control group, 23 cases) between January 2008 and January 2022, were retrospectively analyzed. All complex calf soft tissue defects in the two groups were caused by trauma or osteomyelitis, and there was only one major blood vessel in the calf or no blood vessel anastomosed with the grafted skin flap. There was no significant difference between the two groups in general data such as gender, age, etiology, size of leg soft tissue defect, and time from injury to operation ( P>0.05). The lower extremity functional scale (LEFS) was used to evaluate the sufferred lower extremity function of the both groups after operation, and the peripheral blood circulation score of the healthy side was evaluated according to the Chinese Medical Association Hand Surgery Society's functional evaluation standard for replantation of amputated limbs. Weber's quantitative method was used to detect static 2-point discrimination (S2PD) to evaluate peripheral sensation of the healthy side, and the popliteal artery flow velocity, toenail capillary filling time, foot temperature, toe blood oxygen saturation of the healthy side, and the incidence of complications were compared between the two groups.@*RESULTS@#No vascular or nerve injury occurred during operation. All flaps survived, and 1 case of partial flap necrosis occurred in both groups, which healed after free skin grafting. All patients were followed up 6 months to 8 years, with a median time of 26 months. The function of the sufferred limb of the two groups recovered satisfactorily, the blood supply of the flap was good, the texture was soft, and the appearance was fair. The incision in the donor site healed well with a linear scar, and the color of the skin graft area was similar. Only a rectangular scar could be seen in the skin donor area where have a satisfactory appearance. The blood supply of the distal limb of the healthy limb was good, and there was no obvious abnormality in color and skin temperature, and the blood supply of the limb was normal during activity. The popliteal artery flow velocity in the study group was significantly faster than that in the control group at 1 month after the pedicle was cut, and the foot temperature, toe blood oxygen saturation, S2PD, toenail capillary filling time, and peripheral blood circulation score were significantly better than those in the control group ( P<0.05). There were 8 cases of cold feet and 2 cases of numbness on the healthy side in the control group, while only 3 cases of cold feet occurred in the study group. The incidence of complications in the study group (13.04%) was significantly lower than that in the control group (43.47%) ( χ 2=3.860, P=0.049). There was no significant difference in LEFS score between the two groups at 6 months after operation ( P>0.05).@*CONCLUSION@#Flow-through bridge anterolateral thigh flap can reduce postoperative complications of healthy feet and reduce the impact of surgery on blood supply and sensation of healthy feet. It is an effective method for repairing complex calf soft tissue defects.

Pattern of limb amputations in Liberia

Background: Amputation is one of the oldest known surgical procedures. It has been one of the modalities of applying judgment and treatment. Its method and indications has evolved over time. Modern amputation is regarded as a part of treatment rather than failure of treatment. Amputation is the removal of a limb or part of a limb through on or more bone. When through a joint is referred to as disarticulation. Data on the profile and pattern of amputation in Liberia will add to the body of knowledge. Aim and Objectives: Is to describe the pattern of limb of amputations in Liberia. Also to describe the anatomical variations of limb amputations in Liberia. Patients and Method: A retrospective study of all patients that underwent limb amputation surgeries in the John F Kennedy Memorial (JFK M), Hospital , Monrovia Liberia between January 2010 to December 2015. Results: 100 patients had limb amputations between 2010 and 2015. Males(73) to female(27) ratio were 2.4:1. The age range was 9 - 91 years. Mean age was 42.9 years. The indications for amputations were Trauma 24%, Diabetes 29%, Gangrene (6%), Chronic ulcer (25%), Tumour (5%). Below knee(47%), Above Knee(45%), Below elbow(2%), Above Elbow(2%), Knee Disarticulation(2%), and Big Toe Disarticulation(2%). Conclusion: The profile of Limb amputation in Liberia is not very different from what is obtaining in the region. However the limitations of histology and other investigative procedure have affected the accurate diagnosis of certain conditions like tumours

Retalho sural reverso de pedículo fasciossubcutâneo: relato de caso / Reverse sural flap of the fasciosubcutaneous pedicle: a case report

Introdução: As perdas de substância no terço inferior da perna costumam exigir elaboradas estratégias cirúrgicas para sua reconstrução. Dentre as opções existentes, o uso do retalho sural reverso de pedículo fasciossubcutâneo ou adipofascial reverso, citado na literatura como interessante alternativa, é pouco relatado, se comparado às outras técnicas mais utilizadas. O objetivo deste estudo é apresentar o resultado do tratamento de uma lesão exposta do tendão de Aquiles, realizado com retalho sural reverso de pedículo fasciossubcutâneo, associado à enxertia de pele total no mesmo tempo cirúrgico, discutindo as alternativas técnicas e as vantagens do procedimento. Relato de caso: A.D., 28 anos, portador de lesão complexa em terço distal da perna, decorrente de evolução desfavorável de procedimento ortopédico de reconstrução do tendão de Aquiles rompido em acidente automobilístico, ocorrido há mais de 30 dias, foi submetido à reconstrução da ferida por meio do retalho sural reverso de pedículo fasciossubcutâneo. A evolução pós-operatória foi favorável, não havendo complicações ou intercorrências. Conclusão: A técnica relatada apresentou uma boa opção com resultado satisfatório para a cobertura de lesão de terço inferior da perna com exposição do tendão de Aquiles.

Introduction: Loss of substance in the lower third of the leg usually requires complex surgical procedures for tissue reconstruction. Among the existing options for tissue reconstruction, reverse sural flap of the fasciosubcutaneous pedicle or reverse adipofascial flap, described in the literature as a viable option, has been little studied compared with other techniques. The objectives of this study were to present the results of surgical treatment of a complex injury due to Achilles tendon rupture using the reverse sural flap of the fasciosubcutaneous pedicle concomitantly with total skin grafting and to discuss the advantages of the procedure as well as other surgical alternatives. Case report: A.D., a 28-year-old male patient, presented with a complex injury in the lower third of the leg because of a poor outcome of surgical repair of Achilles tendon rupture that had occurred during an automobile accident more than 30 days previously. The patient underwent injury reconstruction with the reverse sural flap of the fasciosubcutaneous pedicle. The postoperative result was favorable, without complications. Conclusion: The surgical technique described here is satisfactory for treating lesions in the lower third of the leg due to Achilles tendon rupture.

Síndrome do aprisionamento da artéria tibial anterior: relato de caso / Anterior tibial artery entrapment syndrome: case report

A claudicação intermitente é uma queixa geralmente relacionada com oclusão arterial secundária a doença aterosclerótica. Entretanto, em pacientes jovens com queixa de claudicação, outras causas devem ser pesquisadas, como a síndrome do aprisionamento da artéria poplítea, síndrome compartimental crônica, compressões ósseas e arterites. Os autores relatam o caso de um paciente com claudicação intermitente devido à compressão extrínseca da artéria tibial anterior pela membrana interóssea, diagnosticada através de angiorressonância durante manobras de dorsiflexão do pé. A paciente foi tratada com sucesso através da liberação do fator compressivo, evoluindo com melhora dos sintomas.

Lower extremity intermittent claudication is usually related to atherosclerotic disease. The most common non-atherosclerotic causes are arterites, chronic compartmental syndrome, bone compression, and popliteal entrapment syndrome. The authors report a case of a patient with intermittent claudication related to anterior tibial artery entrapment caused by the interosseous membrane. Magnetic resonance angiography showed compression of the anterior tibial artery during dynamic maneuvers and the patient was managed by releasing the cause of compression, resulting in relief from claudication.

Amputación bilateral en paciente diabética con ceguera, el uso de prótesis inadecuadas. Reporte de caso / Bilateral amputation in diabetic patient with blindness, the use of inadequate prosthesis. Case report

Resumen: Las complicaciones más frecuentes asociadas con la diabetes incluyen al pie diabético y al glaucoma, que suelen llevar a la amputación y a la pérdida de la visión, respectivamente. El desarrollo científico y tecnológico actual ha permitido el diseño e implementación de sistemas protésicos óptimos para estos pacientes, asegurando una reincorporación a las actividades de la vida diaria, así como una correcta adaptación al uso de las mismas. La falta de recursos económicos compromete la adquisición de las prótesis ideales, recurriendo al uso de sistemas «artesanales¼ o «rústicos¼ que afectan la adaptación. Se presenta el caso de un paciente femenino de 47 años de edad, ama de casa, quien presenta parestesias bilaterales y sensación de miembro fantasma asociado a neuromas de amputación por diabetes mellitus tipo II de ocho años de evolución. La paciente, con bajos recursos económicos, es evaluada postamputación con diagnóstico de dependencia grave en la ejecución de las actividades de la vida diaria, con desplazamiento en silla de ruedas asistido; esta presentación es una variante frecuente como consecuencia de la pérdida bilateral de miembros inferiores, concomitante a la ausencia total de la visión. Se presenta el tratamiento de rehabilitación en etapa preprotésica y protésica, acompañados por los resultados de las evaluaciones para mostrar la efectividad del proceso terapéutico, sin olvidar la participación del cuidador como ente coterapéutico fundamental en el proceso.

Abstract: The most frequent diabetes-related complications are diabetic foot and glaucoma, which lead to amputation and loss of vision, respectively. Current scientific and technologic developments have permitted the design and implementation of prosthetic systems that are optimal for these patients, as the latter adapt themselves to them and can resume activities of daily living. The lack of economic resources compromises the quality of the prostheses patients can afford, as they resort to «artisanal¼ or «rustic¼ systems that hamper their adaptation process. We present herein the case of a 47 year-old female patient, housewife, with bilateral paresthesias and phantom limb sensation associated with amputation neuromas resulting from type II diabetes mellitus that had affected the patient for eight years. This patient of a low socioeconomic stratum underwent a post-amputation assessment and was diagnosed as being heavily dependent when performing activities of daily living and required assisted wheelchair for ambulation. This is a frequent variant resulting from bilateral loss of lower limbs together with complete loss of vision. We describe the rehabilitation therapy during the pre- and post-prosthetic stages, together with the results of the assessments to show the effectiveness of the treatment process, without forgetting the participation of the caregiver as a fundamental co-therapeutic element in this process.

ABSTRACT: Objective: It was to identify trends of traumatic and non-traumatic causes of lower limb amputations, as well as the role played by population aging, traffic violence increase, public health policy of diabetes control program and drivers anti-alcohol laws on these amputations. Method: Hospitalization data recorded in the discharge forms of 32 hospitals located in the region of Ribeirão Preto, Brazil, from 1985 to 2008 were analyzed. Result: A total of 3,274 lower-limb amputations were analyzed, of which 95.2% were related to non-traumatic causes, mainly infectious and ischemic complications of diabetes mellitus. Cancer (2.8%) and congenital (1.3%) causes were included in this group. Only 4.8% were related to traumatic causes. Traumatic amputation average rate was 1.5 amputations in 100,000 habitants with a slight tendency of increase in the last 5 years. Non-traumatic causes showed an average rate of 30.0 amputations for 100,000 habitants and remained relatively constant during the whole period. Non-traumatic were much more predominant in patients older than 60 years and traumatic amputations occurred more frequently in patients younger than 39 years. Conclusion: The overall rates of amputation and the rates of traumatic and non-traumatic amputations remained nearly constant during the study period. The impact of diabetes control policies and the introduction of traffic safety laws could not be identified on the amputation rates.

RESUMO: Objetivo: Identificar as tendências temporais de causas traumáticas e não traumáticas de amputações de membros inferiores, e os efeitos do envelhecimento da população, do aumento de violência no trânsito, da política de saúde pública do programa de controle de diabetes e das leis de controle do uso de álcool em motoristas sobre as taxas de amputações. Método: Foram analisados os dados das folhas de alta de pacientes submetidos a amputações de todos os 32 hospitais localizados na região de Ribeirão Preto, Brasil, de 1985 a 2008. Resultado: De 3.274 amputações de membros inferiores, 95,2% estavam relacionadas a causas não traumáticas, principalmente complicações do diabetes mellitus. Câncer (2,8%) e causas congênitas (1,3%) foram incluídos neste grupo. Apenas 4,8% estavam relacionados às causas traumáticas. A taxa média de amputação traumática foi de 1,5 amputações por 100.000 habitantes, com uma ligeira tendência de aumento nos últimos 5 anos. As causas não traumáticas mostraram uma taxa média de 30 amputações por 100.000 habitantes e mantiveram-se relativamente constantes durante todo o período. As causas não traumáticas foram predominantes em pacientes com mais de 60 anos, e as amputações traumáticas ocorreram mais frequentemente em pacientes com menos de 39 anos. Conclusão: A taxa total de amputações e as taxas de amputações traumáticas e não traumáticas permaneceram praticamente constantes durante o período de estudo. O impacto das políticas de controle do diabetes e da introdução de leis de repressão do uso de álcool no trânsito não pode ser identificado nas taxas de amputação.

Reconstruções complexas de membros superiores e inferiores com retalhos de fluxo reverso: uma série de 32 casos / Complex reconstruction of the upper and lower limbs by using reverse-flow flaps: a series of 32 cases

Introdução: A reconstrução de partes moles após perdas de substância do terço distal dos membros superiores e inferiores, principalmente quando associada à exposição de estruturas nobres (osso, tendão, nervos ou vasos sanguíneos), continua a desafiar a cirurgia plástica. Os retalhos fasciocutâneos de fluxo reverso são uma eficiente opção cirúrgica na cobertura de lesões pequenas e médias nesta localização. Método: Foi realizado um estudo clínico retrospectivo, no período de janeiro de 2013 a dezembro de 2014, de uma série de 32 casos de traumas complexos em membros superiores e inferiores. Resultados: Foram realizados 24 retalhos de fluxo reverso nos membros inferiores e 8 nos membros superiores, observando-se uma cobertura eficaz dos defeitos. Conclusão: Os retalhos de fluxo reverso são confiáveis e apresentam arcos de rotação que permitem a cobertura de lesões diversas no terço distal de membros superiores e inferiores.

Introduction: Reconstruction of the soft tissues after loss of substance in the distal third of the upper and lower limbs, in particular when associated with the exposure of noble structures (bone, tendon, nerves, or blood vessels), remains a challenge in plastic surgery. Fasciocutaneous reverse flow flaps are an efficient surgical option for covering small and medium lesions in this location. Method: A retrospective clinical study was performed on a series of 32 cases of complex trauma of the upper and lower limbs treated between January 2013 and December 2014. Results: A total of 24 reverse-flow flaps were performed in the lower limbs and eight in the upper limbs, resulting in efficient coverage of the defects. Conclusion: Reverse-flow flaps are reliable and present rotation arcs that allow coverage of a variety of lesions in the distal third of the upper and lower limbs.

Uso de doble colgajo diep para reconstrucción de extremidad inferior / Double diep flap for lower extremities reconstruction

Introduction: A soft tissue defect considering the extent, location, depth and involved structures can be a complex task, leading to search for unusual reconstructive alternatives. Case report: Puerperal woman, 21 years, previously healthy, admitted for septic shock and skin necrosis of both extremities secondary to purpura fulminans. Escharectomy was performed and the final defect was 27 percent of total body surface, corresponding to necrotic areas of both superior and lower extremities. Is remarkable the presence of musculocutaneous perforating vessels thrombosis and segmental muscular necrosis in legs and interosseous muscles necrosis in hands. In upper extremity coverage was performed with dermoepidermal grafts. To cover peroneal malleolus and feet dorsum, whereas there were no regional or local alternatives, we realize a double DIEP flap. Flap elevation of bilateral DIEP flap was performed simultaneously for two surgical teams. The patient had no complications and was discharged with complete soft tissue coverage.

Introducción: Un defecto de cobertura extenso de extremidades inferiores (EEII), considerando ubicación, profundidad y estructuras involucradas es de una alta complejidad y puede llevar a buscar alternativas reconstructivas poco habituales. Caso Clínico: Paciente de 21 años, puérpera, ingresa por shock séptico y necrosis cutánea extensa de extremidades secundario a un purpura fulminans. Se realiza escarectomía y el defecto resultante es de 27 por ciento de superficie corporal, correspondiendo a zonas necróticas en ambas extremidades, superiores e inferiores. Destaca la presencia de trombosis de vasos perforantes musculocutáneos, necrosis muscular segmentaria en piernas y de musculatura interósea en manos. En extremidades superiores se realizó cobertura con injertos dermoepidérmicos. Para la exposición de ambos maléolos peroneos y dorso de pies, considerando que no existen alternativas locales ni regionales, se decide realizar un colgajo DIEP bilateral; se eleva en un tiempo, con dos equipos quirúrgicos simultáneos. La anastomosis microquirúrgica se realizó a los vasos tibiales de cada extremidad. La evolución postoperatoria fue favorable. La paciente es dada de alta en buenas condiciones generales, extubada, con cobertura cutánea completa.

Tromboembolia arterial y amputación de una extremidad en un neonato posterior al síndrome de dificultad respiratoria: Caso clínico / Neonatal arterial thromboembolism and limb loss following respiratory distress syndrome: Case report

La tromboembolia en los recién nacidos es un problema grave. Los factores de riesgo más importantes son iatrogénicos, entre ellos, el uso de sondas umbilicales o vías centrales permanentes. Entre otros factores de riesgo, se incluyen la asfixia, la deshidratación, la septicemia, la cardiopatía, el síndrome de dificultad respiratoria, la coagulación intravascular diseminada, la trombofilia congénita (deficiencia de proteína C o proteína S), la diabetes mellitus materna y la transferencia pasiva de anticuerpos antifosfolípidos maternos. Los recién nacidos son más vulnerables que los adultos a presentar una trombosis debido a su menor capacidad fibrinolítica. Describimos el caso de una recién nacida de un día de vida con tromboembolia arterial en el miembro inferior; sin vía central. La tromboembolia en este caso estuvo asociada con un síndrome de dificultad respiratoria. Se realizó trombólisis; tratamiento anticoagulante y trombectomía quirúrgica. Posteriormente; se amputó el miembro inferior por debajo de la rodilla.

Thromboembolic disease in newborn infants is a serious problem. The most important risk factors are iatrogenic factors, including indwelling umbilical catheters or central catheters. Other risk factors include asphyxia, dehydration, sepsis, cardiac disease, respiratory distress syndrome (RDS), disseminated intravascular coagulation, congenital thrombophilia (i.e., protein C or protein S deficiency), maternal diabetes mellitus, and passive transfer of maternal antiphospholipid antibodies. Neonates are more vulnerable to thrombosis than adults due to their reduced fibrinolytic capability. We describe a case of a 1-day-old female newborn with arterial thromboembolism in the lower leg without a central line catheter. The thromboembolismin in this case was associated with RDS. The infant underwent thrombolysis, anticoagulation therapy, and surgical thrombectomy. The leg of the infant was subsequently amputated below the knee. The case is described here with a brief review of relevant literatures.

Reconstrução de dorso do pé com retalho supramaleolar lateral de fluxo reverso em menor de 4 anos de idade / Reconstruction of the dorsal foot with a retrograde flow lateral supramalleolar flap in a 4-year-old child

INTRODUÇÃO: Lesões em terço distal da perna podem deixar expostas áreas nobres, que devem ser recobertas. O retalho supramaleolar lateral faz parte de uma série de retalhos descritos na última década, é fasciocutâneo elevado no aspecto lateral da perna inferior, sendo empregado como um retalho pediculado com base distal. O objetivo do presente relato de caso é apresentar os resultados cirúrgicos e a eficácia do retalho supramaleolar lateral em lesões extensas no membro inferior com perdas de substâncias significativas em criança de 4 anos. RELATO DE CASO: Paciente A.K.E.S., sexo feminino, foi internada há 13 anos, vítima de atropelamento, com lesão extensa em dorso de pé esquerdo com exposição de áreas nobres de aproximadamente seis centímetros de diâmetro. Após desbridamento, no quinto dia foi realizada cobertura da lesão com retalho fasciocutâneo supramaleolar lateral. A paciente teve alta para acompanhamento ambulatorial, evoluindo sem intercorrência. Ela retornou ao serviço apenas 13 anos após com sobrepeso e reclamando do aumento de volume no dorso do pé. Foi realizada lipectomia do terço distal do retalho, evoluindo sem intercorrência. Um segundo procedimento do terço proximal foi programado para seis meses após. DISCUSSÃO: Lesões no terço distal da perna podem expor áreas nobres. Os retalhos supramaleolar lateral, sural e de perfurantes pediculados possuem aplicações semelhantes, mas apresentam peculiaridades técnicas individuais. Como vantagens no retalho supramaleolar lateral: não há necessidade de microanastomoses, é rápido para ser executado e simula a área receptora em várias características locais. CONCLUSÃO: É um retalho de maior facilidade de execução e reprodutível, podendo ser realizado em crianças menores de 5 anos. Tem sua aplicação como alternativa para lesões em terços inferiores da perna, tornozelo e pé.

INTRODUCTION: Injuries in the distal third of the leg may expose noble areas that should be covered. The lateral supramalleolar flap is one of a series of flaps described in the last decade; it is an elevated fasciocutaneous flap in the lateral aspect of the lower leg, and is employed as a distally based pedicled flap. The purpose of this case report is to present the surgical results and the effectiveness of the lateral supramalleolar flap in extensive lower limb injuries with significant loss of substance in a 4-year-old child. CASE REPORT: Patient A. K. E. S., a girl, was admitted 13 years previously. She had been in an accident, and had extensive injuries on the dorsum of the left foot, with exposure of noble areas approximately 6 cm in diameter. After debridement, lesion coverage was performed on the fifth day by using a fasciocutaneous lateral supramalleolar flap. The patient was discharged for outpatient monitoring and progressed without complication. She only returned to the hospital 13 years later, overweight and complaining of swelling on the dorsal aspect of the foot. Lipectomy of the distal third of the flap was performed, with uncomplicated progress. A second procedure for the proximal third was scheduled six months later. DISCUSSION: Injuries in the distal third of the leg may expose noble areas. Lateral supramalleolar, sural, and pedicled perforating flaps have similar applications, but show individual technical peculiarities. The lateral supramalleolar flap has no need for microsurgery, is rapidly performed, and simulates the receiving area while considering several local characteristics. CONCLUSION: This flap is easily implemented and reproducible, and can be used in children younger than 5 years of age. It is an alternative for injuries in the lower third of the leg, the ankle, and the foot.

Tratamento das áreas cruentas de perna com retalhos locais / Treatment of open wounds of the leg by using local flaps

INTRODUÇÃO: Até os anos 70, a reparação de perdas de substância na perna representava, quase sempre, um problema de solução muito difícil ou, até, insolúvel. Atualmente, embora ainda constitua um campo para os mais experientes, as áreas cruentas na perna já contam com várias técnicas confiáveis e algumas relativamente simples para sua reparação. Este trabalho visa equacionar condutas reparadoras de feridas de perna, utilizando tecidos locais. MÉTODO: Estudo retrospectivo pela análise de casos de reconstrução de perna com retalhos locais realizados pelos autores. Foram incluídos os retalhos dermoadiposos, fasciocutâneos, fasciossubcutâneos e musculares. RESULTADOS: Foram operados 70 pacientes que possuíam áreas cruentas na perna, em consequência de fratura de tíbia, osteomielite, perda tecidual isquêmica, úlcera crônica e tumoração de pele. Os resultados foram avaliados segundo etiologia, tipo de procedimento cirúrgico e complicações. CONCLUSÕES: A opção do tratamento de áreas cruentas de membros inferiores com retalhos locais é bastante válida. A escolha do retalho vai depender de condições locais da perna e da região anatômica afetada. No terço superior da perna, utilizamos retalhos fasciocutâneos baseados na rede vascular do joelho ou retalho de gastrocnêmio. Já no médio, os principais retalhos foram o solear e o fasciossubcutâneo de panturrilha. E, por fim, no inferior, o principal retalho usado foi o fasciossubcutâneo de panturrilha.

INTRODUCTION: Until the 70s, repairing loss of tissue in the leg was almost always difficult, or even impossible. Currently, only the most experienced surgeons are able to repair open wounds of the leg. Nevertheless, several reliable and simple techniques are currently available. This work aimed to evaluate repair techniques for leg wounds by using local tissues. METHOD: The authors performed a retrospective study of cases of leg reconstruction using local flaps. Dermoadipose, fasciocutaneous, fasciosubcutaneous, and muscle flaps were used. RESULTS: Seventy patients who had open areas in the leg due to tibial fractures, osteomyelitis, ischemic tissue loss, chronic ulcer, or skin tumor underwent surgery. Results were evaluated according to etiology, type of surgical procedure, and complications. CONCLUSIONS: The option of treating open wounds of the lower limbs by using local flaps is very valid. Selection of the flap type depended on local conditions in the leg, and the anatomical region affected. In the upper third of the leg, we used fasciocutaneous flaps, based on the vascular network of the knee, or gastrocnemius flaps. In the middle third of the leg, we used the soleus muscle as the primary flap, and fasciosubcutaneous flaps in the calf region. In the lower third of the leg, a fasciosubcutaneous flap of the calf was primarily used.

Incidence of Deep Vein Thrombosis after Major Lower Limb Orthopedic Surgery: Analysis of a Nationwide Claim Registry

PURPOSE: We aimed to evaluate the nationwide incidence and risk factors for symptomatic deep vein thrombosis (DVT) after major lower limb orthopedic surgeries. MATERIALS AND METHODS: The Korean Health Insurance Review and Assessment Service database was used to retrospectively identify International Classification of Disease-10 codes for DVT and operation codes representing hip arthroplasty, knee arthroplasty, and hip fracture surgeries. The age- and gender-adjusted annual incidence of DVT, rates of major lower limb orthopedic surgeries, and the postoperative incidence of DVT according to the surgical procedure were assessed. RESULTS: The age- and gender-adjusted annual incidence of DVT was 70.67 per 100000 persons/year. Compared to patients aged 70 years (p<0.001). Females showed a greater relative risk for DVT than males (1.08; p<0.001). The incidence of postoperative DVT, according to the type of surgery, was significantly greater for knee replacement arthroplasty than for other forms of surgery (p<0.002). The relative risk of postoperative DVT was higher in females in knee replacement arthroplasty (1.47) and hip fracture surgery (2.25) groups, although relatively lower in those who underwent hip replacement arthroplasty (0.97). CONCLUSION: Among major lower limb surgeries, advanced age, female gender, and undergoing a knee replacement arthroplasty were found to be risk factors for developing postoperative DVT. These findings further emphasize the need for orthopedic surgeons to consider the development of DVT after surgery in high-risk patients.

Use of local muscle flaps to cover leg bone exposures / Uso de retalhos musculares locais para cobertura de exposições ósseas na perna

Objective: To evaluate the use of the medial gastrocnemius muscle and/or soleus muscle flaps as surgical treatment of the leg bone exposure. Methods: We retrospectively analyzed the medical records of patients undergoing transposition of the medial gastrocnemius and / or soleus for treating exposed bone in the leg, from January 1976 to July 2009, gathering information on epidemiological data, the etiology the lesion, the time between the initial injury and muscle transposition, the muscle used to cover the lesion, the healing evolution of the skin coverage and the function of the gastrocnemius-soleus unit. Results: 53 patients were operated, the ages varying between nine and 84 years (mean age 41); 42 were male and 11 female. The main initial injury was trauma (84.8%), consisting of tibia and / or fibula fracture. The most frequently used muscle was the soleus, in 40 cases (75.5%). The rank of 49 patients (92.5%) was excellent or good outcome, of three (5.6%) as regular and of one (1.9%) as unsatisfactory. Conclusion: the treatment of bone exposure with local muscle flaps (gastrocnemius and/or soleus) enables obtaining satisfactory results in covering of exposed structures, favoring local vascularization and improving the initial injury. It offers the advantage of providing a treatment in only one surgical procedure, an earlier recovery and reduced hospital stay. .

Objetivo: avaliar o uso de retalhos de porção medial do músculo gastrocnêmio e/ou de músculo sóleo como tratamento cirúrgico de exposição óssea da perna. Métodos: foram analisados, retrospectivamente, os prontuários de pacientes submetidos à transposição dos músculos gastrocnêmio medial e/ou sóleo para tratar exposição óssea na perna, no período de janeiro de 1976 a julho de 2009. Foram avaliados, além dos dados epidemiológicos, a etiologia da lesão, o intervalo de tempo decorrido entre a lesão inicial e a transposição muscular, o músculo utilizado para cobrir a lesão, a evolução da cicatrização da cobertura cutânea e a função da unidade gastrocnêmio-sóleo. Resultados: foram operados 53 pacientes, variando a faixa etária entre 09 e 84 anos (média de idade de 41 anos), sendo 42 do sexo masculino e 11 do sexo feminino. A lesão inicial principal foi de origem traumática (84,8%), consistindo de fratura de tíbia e/ou fíbula. O músculo utilizado com maior frequência foi o sóleo em 40 casos (75,5%). Classificou-se 49 pacientes (92,5%) como resultado excelente ou bom, 03 (5,6%) como regular e 01 (1,9%) como insatisfatório. Conclusão: o tratamento da exposição óssea com retalhos musculares locais (gastrocnêmio e ou sóleo) possibilita a obtenção de resultados satisfatórios na cobertura das estruturas expostas, favorecendo a vascularização local e melhora da lesão inicial. Apresenta como vantagens a realização do tratamento em um só tempo cirúrgico, uma recuperação mais precoce e diminuição do tempo de internação. .

Ossificação do pedículo vascular de um retalho livre de fíbula: relato de caso / Ossification of vascular pedicle in fibula free flap: a case report

Introdução: Várias são as vantagens da utilização de retalhos fibulares para as reconstruções de defeitos craniomaxilofaciais, incluindo a baixa morbidade da área doadora, boa qualidade óssea possibilitando a realização de implantes osteointegrados quando indicados, além da possibilidade de inclusão de uma ilha de pele quando indicado. Durante a dissecção do retalho, próximo à região do pedículo vascular, normalmente inclui-se um cuff muscular e uma faixa de periósteo. O potencial osteogênico do periósteo transplantado tem sido objeto de estudo. Relato de caso: paciente de 15 anos, submetido à reconstrução microcirúrgica com um retalho fibular para um defeito mandibular pós-ressecção de um sarcoma ósseo. Evoluiu com aumento de volume, de consistência óssea na região cervical próximo à cervicotomia realizada para anastomose vascular. Exames de imagem mostravam características ósseas da massa. Foi então submetido à nova cervicotomia e exploração da massa, sendo observada uma formação de tecido ósseo no local da anastomose vascular. Exame anatomopatológico da peça mostrava formação de tecido ósseo adjacente ao retalho periostal. Discussão: Durante a dissecção do retalho fibular, a osteotomia é realizada a alguns centímetros da articulação do joelho, isto a fim de facilitar a dissecção do pedículo vascular na região do oco poplíteo. O pedículo vascular fica então envolto por uma cuff muscular e por uma tira de periósteo. Este mantém sua capacidade osteogênica, que pode ser ativada de acordo com o estímulo do local. A ossificação do periósteo do pedículo vascular de retalhos livres de fíbula permanece um evento raro, porém relatado por centros diferentes.

Introduction: The use of fibula flaps for the reconstruction of craniomaxillofacial defects has many advantages, including the low morbidity of the donor area, good bone quality for use of osseointegrated implants, and the possibility to include a skin island, when indicated. During the dissection of the flap, a muscle "cuff" and a periosteal strip are usually included near the region of the vascular pedicle. The osteogenic potential of the transplanted periosteum has been the object of studies. Case report: A 15-year-old male patient underwent microsurgical reconstruction using a fibula flap for a mandibular defect caused by the resection of a bone sarcoma. He developed increased volume and bone consistency in the cervical region next to the area where a cervicotomy was performed for vascular anastomosis. Imaging examinations showed the characteristics of the bone mass. He then underwent a new cervicotomy and mass exploratory surgery because bone tissue formation was observed at the site of vascular anastomosis. Anatomopathological examination of the specimen showed bone tissue formation next to the periosteal flap. Discussion: During fibula flap dissection, osteotomy is performed a few centimeters from the knee joint to facilitate the dissection of the vascular pedicle in the region of the popliteal fossa. Then, the vascular pedicle is surrounded by a muscle cuff and periosteal strip. This maintains its osteogenic capacity, which can be activated according to the stimulus of the area. Although periosteal ossification of the vascular pedicle in fibula free flaps is a rare event, it has been reported in different centers.

A Case of Nonisland Pedicled Foot Fillet Flap for Below-Knee Amputation Stump Wound: Treatment Option for Compartment Syndrome after Fibular Free Flap Surgery

Despite the frequent use of the fibular free flap, there have been no reports of severe compartment syndrome of the donor leg that necessitated limb amputation. A 66-yr-old man had a fibular osseous free flap transfer from the left leg to the mandible that was complicated by postoperative compartment syndrome. An extensive chronic leg wound resulted, which was treated with multiple debridements and finally with below-knee amputation. Successful coverage of the below-knee amputation stump was accomplished with a nonisland pedicled foot fillet flap. Various foot fillet flaps may be used acutely as a free or an island pedicled flap, but dissection of the vascular pedicle may be difficult in a chronically inflamed wound because of inflammation and adhesions to surrounding tissue. The nonisland pedicled foot fillet flap may be considered as a useful option for treatment of a chronically inflamed stump wound after below-knee amputation.

Diabetes-related lower-extremity amputation incidence and risk factors: a prospective seven-year study in Costa Rica / Incidencia y factores de riesgo de la amputación de extremidades inferiores relacionada con la diabetes: estudio prospectivo de siete años en Costa Rica

Objective. To analyze the incidence and determinants of lower-extremity amputation(LEA) in people with diabetes in a low-income community in Costa Rica.Methods. Data on LEA incidence were collected during a seven-year follow-up (2001–2007) in a diabetes patient cohort (n = 572). Risk factors were analyzed using the Coxproportional hazards regression model and baseline variables from the year 2000 (sociodemographiccharacteristics, comorbidity, metabolic control, treatment, and chronic microvascularcomplications).Results. LEA incidence was 6.02 per 1 000 person-years (8.65 in men and 4.50 in women).Known risk factors (sex, years of diabetes, elevated glycated hemoglobin [HbA1c], retinopathy,insulin therapy, and prior amputation) were highly significant.Conclusions. Those most likely to undergo LEA among Costa Rican diabetic patients weremen with 10 or more years of diabetes and average HbA1c ≥ 8% who used insulin and haddiabetic retinopathy. Patients on insulin therapy were at greatest risk, especially those with aprevious amputation. Diabetic patients with the above-mentioned profile should be consideredto be at very high risk of LEA and followed closely by the health care system.

Objetivo. Analizar la incidencia y los determinantes de la amputación deextremidades inferiores (AEI) en personas diabéticas de una comunidad con bajosingresos de Costa Rica.Métodos. Se recopilaron datos sobre la incidencia de la AEI durante un período deseguimiento de siete años (del 2001 al 2007) en una cohorte de pacientes diabéticos(n = 572). Se analizaron los factores de riesgo usando el modelo de regresión de Coxde riesgos proporcionales y los valores de referencia del año 2000 de las variables(características sociodemográficas, comorbilidad, control metabólico, tratamiento ycomplicaciones microvasculares crónicas).Resultados. La incidencia de la AEI fue de 6,02 por 1 000 personas-año (8,65 envarones y 4,50 en mujeres). Los factores de riesgo conocidos (sexo, años de evoluciónde la diabetes, glucohemoglobina [HbA1c] elevada, retinopatía, tratamiento coninsulina y amputación previa) fueron muy significativos.Conclusiones. Los pacientes diabéticos costarricenses con mayor probabilidad desufrir una AEI fueron los varones con 10 o más años de evolución de la diabetesy un promedio de HbA1c ≥ 8% que eran tratados con insulina y padecían unaretinopatía diabética. Los pacientes en tratamiento con insulina presentaban el mayorriesgo, especialmente los que habían sufrido una amputación anterior. Los pacientesdiabéticos con el perfil descrito anteriormente deben considerarse como de riesgomuy elevado de AEI y deben ser seguidos de cerca por el sistema de atención desalud.
