Introducción: La amputación provoca discapacidad física e invalidez como consecuencia de la enfermedad vascular periférica. Objetivo: Caracterizar a los pacientes amputados de miembros inferiores por causas vasculares en el municipio Cerro. Métodos: Se realizó un estudio descriptivo en los 114 amputados de miembros inferiores que estaban registrados, entre 2016 y 2018, en la Dirección Municipal de Salud del municipio Cerro. La muestra quedó constituida por los 64 amputados de causa vascular. Las variables de estudio fueron: edad, sexo, factores de riesgo, tipo de amputación y su nivel, miembro más afectado y causa vascular de amputación. Se estimaron las frecuencias absolutas y relativas, y la prueba de chi cuadrado, para identificar la asociación entre las variables. Resultados: Hubo predominio de los amputados de causa vascular (56,1 por ciento), el sexo femenino (54,7 por ciento), el grupo etáreo de 60 años y más (84,4 por ciento), y la HTA y el tabaquismo (ambos con 60,9 por ciento). La amputación supracondílea fue la más realizada (64,1 por ciento). El pie diabético isquémico y la aterosclerosis obliterante resultaron las causas vasculares que provocaron los mayores porcentajes de amputación. Se halló asociación altamente significativa entre el sexo masculino y la ateroesclerosis obliterante (X2 = 5,4; p = 0,113, OR = 2,68 y RR = 1,81), lo que señaló a este como un factor de riesgo de amputación. Conclusiones: Las amputaciones aparecieron con mayor frecuencia en las mujeres mayores de 60 años, del tipo supracondílea y por pie diabético como causa vascular. La ateroesclerosis obliterante en los hombres constituyó un factor de riesgo de amputación(AU)

Introduction: Amputation as a result of peripheral vascular disease causes physical disability and impairment. Objective: Characterize amputee patients of lower limbs due to vascular causes in Cerro municipality. Methods: A descriptive study was carried out in the 114 lower limbs amputee patients that were registered, between 2016 and 2018, in the Municipal Health Division of Cerro municipality. The sample consisted of the 64 vascular-cause amputees. The study variables were: age, sex, risk factors, type of amputation and its level, most affected limb and vascular cause of amputation. Absolute and relative frequencies were estimated, and the chi square test was used to identify the association between variables. Results: There was predominance of vascular-cause amputees (56.1 percent), the female sex (54.7 percent), the 60-year-old and older age group (84.4 percent), and HTA and smoking having (both 60.9 percent). Supracondylar amputation was the most performed one (64.1 percent). Ischemic diabetic foot and obliterating atherosclerosis resulted in the vascular causes that produce the highest percentages of amputation. A highly significant association was found between the male sex and obliterating atherosclerosis (X2 = 5.4; p = 0.113; OR = 2.68 and RR = 1.81), which pointed to this as an amputation risk factor. Conclusions: Amputations most often appeared in women over the age of 60, as supracondyle type and diabetic foot as a vascular cause. Obliterating atherosclerosis in men was a risk factor for amputation(AU)

SUMMARY OBJECTIVE: The aim of this study was to investigate the levels of physical activity (PA) and quality of life (QOL) in adults and elderly individuals with lower limb amputation (LLA). METHODS: This was a cross-sectional observational study. Participants completed three surveys as follows: a demographic survey, the International Physical Activity Questionnaire, and the World Health Organization Quality of Life. Thirty-six individuals with lower limb amputation were separated into two different groups as follows: Adults-lower limb amputation (n=12), composed of individuals with lower limb amputation who aged from 18-59 years, and Elderly-lower limb amputation (n=24), composed of individuals with lower limb amputation who aged 60 years and above. Statistical differences were determined as p<0.05. RESULTS: Age and number of individuals with a low level of functional independency were higher in the Elderly-lower limb amputation group (p<0.05). The International Physical Activity Questionnaire scores were reduced in the Elderly-lower limb amputation group (p<0.05). The Pearson's correlation test between low metabolic equivalent task (MET), time since amputation, and family income presented positive significant results in the Elderly-lower limb amputation (p<0.05). Adults-lower limb amputation just presents a positive significant correlation with the low family income (p<0.05). CONCLUSION: Elderly individuals with lower limb amputation are more susceptible to present negative health outcomes than adults with lower limb amputation.

OBJECTIVE@#To explore the treatment methods and experience of open fracture of lower limb in high altitude area.@*METHODS@#From January 2016 to January 2021, 62 patients with open fractures of lower limbs were treated by staged surgery with the concept of injury control orthopedics, emphasizing wound treatment and combining various fracture fixation methods. There were 51 males and 11 females, ranging in age from 14 to 59 years old, with a mean of (37.2±12.3) years old; and the course of disease ranged from 7 to 59 days, with a mean of (23.7±15.5) days. According to Gustilo Anderson classification, there were 14 cases of typeⅠ, 24 cases of typeⅡ, 14 cases of typeⅢA, 8 cases of typeⅢB and 2 cases of typeⅢC. The fracture repair and wound healing were observed, and the clinical efficacy was evaluated by Johner-Wruhs evaluation standard.@*RESULTS@#Fifty-five patients were followed up, and the duration ranged from 4 to 36 months, with a mean of (14.7±8.5) months, and 7 cases were lost to follow-up. According to Johner-Wruhs evaluation criteria, 33 cases got an excellent result, 16 good, 4 poor and 2 bad. The wound healing was poor in 2 cases, partial necrosis of Achilles tendon in 1 case, nonunion of fracture in 1 case and delayed healing of fracture in 2 cases.@*CONCLUSION@#It is an effective method to treat the open fracture of lower extremity in high altitude area to pay attention to the management of soft tissue injury, the management of wound moisturizing, staged operation of fracture and full protection of blood supply at the fracture end. Paying attention to the treatment of soft tissue injury and the management of wound moisturizing, staged operation of fracture and full protection of blood supply at the fracture end are effective methods for the treatment of open fracture of lower limbs in high altitude areas.

OBJECTIVE@#To discuss the clinical effect of antibiotic bone cement in the treatment of infectious wound of lower extremity.@*METHODS@#From January 2016 to January 2019, 28 patients who had infection wounds of lower extremity were treated by antibiotic bone cement, including 21 males and 7 females with age of 34 to 76 (53.8±16.5) years old. The wound area after the initial debridement was 4 cm×3 cm to 12 cm×8 cm. All patients were treated with the antibiotic bone cement, when infection was controlled and fresh granulation tissue grew on the wound surface, local sutures or skin grafts were performed. The changes of white blood cell (WBC), erythrocyte sedimentation rate(ESR), C reactive protein(CRP) and positive rate of bacterial culture of wound secretions were recorded andcompared before and after 2 weeks of the operation. The healing time, recurrence rate and complications of fresh granulation on wound surface were calculated.@*RESULTS@#All patients were followed up for 3 to 6(4.3±1.2) months. After the recurrence of diabetic foot wound infection, 3 patients presented different degree of rupture, and the remaining patients had good wound healing. No serious complications such as aggravation of infection and amputation occurred. The WBC, ESR and CRP of the patients were decreased significantly after operation compared with that before operation (9.1±1.2)×109/L vs. (11.4±2.2)×109/L, (23.5±7.6) mm/ h vs. (57.1±14.9) mg/L, (44.2±13.1) mg/L vs. (89.2±26.7) mg/L (@*CONCLUSION@#The antibiotic bone cement can control infection of lower extremity wound effectively, promote the growth of fresh granulation tissue and wound healing.

RESUMEN Introducción: La cobertura de dispositivos ortopédicos expuestos y las infecciones en el hueso con colgajos es un tema controvertido. No existe un consenso claro sobre el tratamiento de esta complicación. En los últimos años se aprecia una tendencia a mantener el material de osteosíntesis y a controlar la infección aportando tejido bien vascularizado en forma de colgajo muscular o fasciocutáneo. Objetivo: Evaluar el éxito reconstructivo con colgajos de defectos de partes blandas en miembros que han precisado de una osteosíntesis, en función de la presencia de infección y el estado de los dispositivos de implante en el momento de la reconstrucción. Métodos: Estudio retrospectivo de una serie de 15 casos con un defecto de partes blandas en las extremidades inferiores secundario a la implantación de dispositivos ortopédicos en el hueso. Todos los casos recibieron cobertura con un colgajo muscular o fasciocutáneo con o sin retirada de los implantes. Se estudió la presencia o ausencia de infección previa a la reconstrucción (signos clínicos, resultado del cultivo microbiológico y exposición del material ortopédico), la retirada o mantenimiento del implante durante la reconstrucción, y la presencia de complicaciones posoperatorias. Se relacionaron estas variables con el éxito reconstructivo posoperatorio. El análisis de las variables se realizó con los estadísticos chi cuadrado, Wilcoxon y U de Mann Whitney, según el tipo de variable, y para una significación de 0,05. Resultados: La frecuencia de éxito reconstructivo fue mayor en aquellos pacientes con cultivo negativo sin exposición de material óseo (p = 0,038). Se encontró menor tasa de complicaciones en los pacientes que presentaban infección antes de la reconstrucción (p = 0,039), y en aquellos con cultivo positivo y exposición del material previos a la cirugía, cuyos implantes habían sido retirados durante la reconstrucción (p = 0,032). Conclusiones: El aporte de tejido bien vascularizado en forma de colgajo permite el mantenimiento del material ortopédico con una frecuencia de éxito de 66,67 %, y resultados favorables de mediano a largo plazo. La exposición y el resultado del cultivo son indicadores predictivos de los resultados de la cirugía(AU)

ABSTRACT Introduction: The covering of exposed orthopedic devices and bone infections with flaps are a controversial issue. There is no clear consensus concerning the treatment of this complication. In recent years, there has been a trend to maintain the osteosynthesis material and to control the infection by providing well vascularized tissue in the form of a muscular or fasciocutaneous flap. Objective: To assess the reconstructive success with flaps of soft tissue defects in limbs that have required osteosynthesis, based on the presence of infection and the status of the implant devices at the time of reconstruction. Methods: Retrospective study of a series of 15 cases with soft tissue defect in the lower limbs after implantation of orthopedic devices to the bone. All the cases were covered with muscle or fasciocutaneous flap, with or without removal of the implants. The presence or absence of infection prior to reconstruction (clinical signs, results of microbiological culture, and exposure of the orthopedic material), removal or maintenance of the implant during reconstruction, and the presence of postoperative complications were studied. These variables were associated with postoperative reconstructive success. The analysis of the variables was performed using the chi-square, as well as Wilcoxon and Mann Whitney U tests, according to the type of variable, and for a significance of 0.05. Results: The frequency of reconstructive success was higher in those patients with negative culture and without exposure of bone material (P=0.038). A lower rate of complications was found in patients with infection before reconstruction (P=0.039), and in those with positive culture and exposure of the material prior to surgery, whose implants had been removed during reconstruction (P=0.032). Conclusions: The provision of well vascularized tissue in the form of flap allows maintenance of the orthopedic material with a success rate of 66.67%, as well as favorable outcomes in the mid to long terms. The results of exposure and culture are predictive indicators of surgery outcomes(AU)

El traumatismo de miembros inferiores representa un reto para el cirujano plástico en cuanto a su reconstrucción cuando no se dispone de técnicas microquirúrgicas. En el presente trabajo se presentan tres casos de reconstrucción de rodilla con doble colgajo muscular de gemelo en donde se demuestra que la utilización simultánea de los dos gemelos puede ser aplicada sin dejar ninguna secuela en la parte funcional y estética en la deambulación de los pacientes. No existe en la literatura nacional ni internacional un reporte de casos con esta aplicación, ya que siempre se ha limitado al uso de un solo músculo precisamente por el temor de alterar la función en cuanto a la flexoextensión del pie.

Lower limb trauma is a challenge for plastic surgeons in their reconstruction when microsurgical techniques are available. In this paper we present three cases of reconstruction of the knee with twin double-muscle flap where it is shown that the simultaneous use of the twins can be applied without leaving any sequel partly functional and aesthetics in ambulation of patients. For there is in the national or international literature a repost of cases with this application as it has always been limited to using just a single muscle for fear of disrupting the function in terms of flexion and extension of the foot.

Introdução: Atualmente com o aumento das gastroplastias redutoras (cirurgia bariátrica) e grande perda ponderal, há também um aumento na procura destes pacientes pela cirurgia plástica. Uma das características destes pacientes é o excesso de tecido dermogorduroso que causa deformidades, principalmente nos membros inferiores, acometendo a região trocantérica. Objetivo: Relatar um caso de dermolipectomia trocantérica em paciente pós-cirurgia bariátrica, onde a lipoaspiração por si só não resolveria a correção da deformidade. Relato de caso: IPMS, sexo feminino, 55 anos, histórico de gastroplastia redutora (cirurgia bariátrica) com grande perda ponderal. Relata desconforto importante com a lipodistrofia e extensa flacidez em região trocantérica bilateral. Após avaliação pela equipe, foi optado por realizar dermolipectomia trocantérica bilateral, em janeiro de 2019, no Serviço de Cirurgia Plástica Osvaldo Saldanha. Discussão: Nos casos de lipodistrofia trocantérica com deformidades graves, a cicatriz da dermolipectomia em relação à deformidade é favorável quanto a escolha desta técnica, pois a lipoaspiração poderá agravar ainda mais a deformidade, sendo mandatório utilizar a técnica de dermolipectomia trocantérica para corrigila. Quanto à lipodistrofia com deformidade moderada há dúvida entre a relação do benefício e a deformidade resultante, sendo aplicada a técnica de acordo com a necessidade do paciente e, por fim, nos casos de lipodistrofia com deformidade leve, opta-se pela lipoaspiração devido à correção ser realizada sem grandes cicatrizes aparentes. Conclusão: Portanto, a lipoaspiração tem benefício nos casos de adiposidade localizada, limitando as indicações da técnica de dermolipectomia, em especial na região trocantérica, sem invalidá-la para casos selecionados, como o descrito neste relato de caso.

Introduction: Currently, with the increase in reducing gastroplasty (bariatric surgery) and the great weight loss, there is also an increase in the demand of these patients for plastic surgery. One of the characteristics of these patients is the excess of dermal adipose tissue that causes deformities, especially in the lower limbs, affecting the trochanteric region. Objective: To report a case of trochanteric dermolipectomy in a patient after bariatric surgery, where liposuction alone would not solve the correction of the deformity. Case report: IPMS, female, 55 years old, history of reducing gastroplasty (bariatric surgery) with great weight loss. She reports significant discomfort with lipodystrophy and extensive flacidity in the bilateral trochanteric region. After the team's evaluation, it was decided to perform bilateral trochanteric dermolipectomy, in January 2019, at the Plastic Surgery Service Osvaldo Saldanha Discussion: In cases of trochanteric lipodystrophy with severe deformities, the scar of dermolipectomy in relation to the deformity is favorable in terms of the choice of this technique, since liposuction may further aggravate the deformity, and it is mandatory to use the trochanteric dermolipectomy technique to correct it. Conclusion: Therefore, liposuction is beneficial in cases of localized adiposity, limiting the indications for the dermolipectomy technique, especially in the trochanteric region, without invalidating it for selected cases, as described in this case report.

Abstract Background and objectives One of the disadvantages of unilateral spinal anesthesia is the short duration of post-operative analgesia, which can be addressed by adding adjuvants to local anesthetics. The aim of current study was to compare the effects of adding dexmedetomidine, fentanyl, or saline to bupivacaine on the properties of unilateral spinal anesthesia in patients undergoing calf surgery. Methods In this double-blind clinical trial, 90 patients who underwent elective calf surgery were randomly divided into three groups. The spinal anesthetic rate in each of the three groups was 1 mL bupivacaine 0.5% (5 mg). In groups BD, BF and BS, 5 µg of dexmedetomidine, 25 µg of fentanyl and 0.5 mL saline were added, respectively. The duration of the motor and sensory blocks in both limbs and the rate of pain during 24 h after surgery were calculated. Hemodynamic changes were also measured during anesthesia for up to 90 min. Results The duration of both of motor and sensory block was significantly longer in dependent limb in the BF (96 and 169 min) and BD (92 and 166 min) groups than the BS (84 and 157 min) group. Visual Analog Scale was significantly lower in the two groups of BF (1.4) and BD (1.3), within 24 h after surgery, than the BS (1.6) group. Conclusions The addition of fentanyl and dexmedetomidine to bupivacaine in unilateral spinal anesthesia can increase the duration of the motor and sensory block in dependent limb and prolong the duration of postoperative pain. However, fentanyl is more effective than dexmedetomidine.

Resumo Justificativa e objetivos Uma das desvantagens da raquianestesia unilateral é a curta duração da analgesia pós-operatória, que pode ser abordada pela adição de adjuvantes aos anestésicos locais. O objetivo deste estudo foi comparar os efeitos da adição de dexmedetomidina, fentanil ou solução salina à bupivacaína sobre as propriedades da raquianestesia unilateral em pacientes submetidos à cirurgia de panturrilha. Métodos Neste ensaio clínico duplo-cego, 90 pacientes submetidos à cirurgia eletiva de panturrilha foram randomicamente divididos em três grupos. A quantidade de anestésico para a raquianestesia nos três grupos foi de 1 mL de bupivacaína a 0,5% (5 mg). Nos grupos BD, BF e BS, 5 µg de dexmedetomidina, 25 µg de fentanil e 0,5 mL de solução salina foram adicionados, respectivamente. Foram calculados a duração dos bloqueios motor e sensorial em ambos os membros e o escore de dor durante 24 horas após a cirurgia. As alterações hemodinâmicas também foram medidas durante a anestesia por até 90 minutos. Resultados A duração de ambos os bloqueios, motor e sensorial, foi significativamente maior no membro dependente nos grupos BF (96 e 169 min) e BD (92 e 166 min) do que no grupo BS (84 e 157 min). Os escores da escala visual analógica foram significativamente menores nos grupos BF (1,4) e BD (1,3) do que no grupo BS (1,6) nas 24 horas após a cirurgia. Conclusões A adição de fentanil e dexmedetomidina à bupivacaína em raquianestesia unilateral pode aumentar a duração dos bloqueios sensorial e motor no membro dependente e prolongar a duração da dor pós-operatória. Contudo, fentanil é mais eficaz do que dexmedetomidina.

RESUMO A isquemia crítica de membro inferior (ICMI) gera impacto nos sistemas de saúde, na qualidade de vida e funcionalidade dos indivíduos diagnosticados. Entretanto, há pouca evidência científica que permita fundamentar a intervenção fisioterapêutica para pacientes internados por ICMI. O objetivo desse estudo foi elaborar um consenso de especialistas sobre a fisioterapia intra-hospitalar para pacientes com ICMI. Para tal, foi utilizado o método Delphi. Um painel de especialistas foi formado por 18 fisioterapeutas que representavam 85,7% da equipe de um hospital de referência em cirurgia vascular. Foram consideradas, para o consenso, as respostas com valor mínimo de concordância de 70% e média ou mediana ≥3,1 na escala Likert. Os questionários abordaram itens da avaliação, objetivos e condutas fisioterapêuticas nas fases pré e pós-cirurgia de revascularização. Definiram-se como itens essenciais a avaliação de sintomas, função cognitiva, musculoesquelética e cardiorrespiratória. Controle da dor, redução de edemas, ganho de amplitude de movimento, deambulação e educação em saúde são objetivos no pré-operatório e o ganho de força muscular na fase pós-operatória. Exercícios passivo, assistido, ativo livre e circulatório, incluindo os membros superiores, estão indicados antes e após as cirurgias. Educação em saúde e deambulação com redução de peso em área de lesão plantar são essenciais em todo o período de internação. A eletroanalgesia foi preconizada no pré-operatório e a elevação do membro inferior e exercícios resistidos no pós-operatório.

RESUMEN La isquemia crítica de miembro inferior (ICMI) afecta a los sistemas de salud y la calidad de vida y funcionalidad de los individuos diagnosticados. Sin embargo, hay poca evidencia científica que fundamente la intervención fisioterapéutica para pacientes internados por ICMI. El objetivo de este estudio fue elaborar un consenso de especialistas sobre la fisioterapia intrahospitalaria para pacientes con ICMI. Para ello, se utilizó el método Delphi. Se formó un panel de expertos con 18 fisioterapeutas que representaban el 85,7% del equipo de un hospital de referencia en cirugía vascular. Se consideraron, para el consenso, las respuestas con un valor mínimo de concordancia del 70% y media o mediana ≥3,1 en la escala Likert. Los cuestionarios abordaron ítems de evaluación, objetivos y conductas fisioterapéuticas en las fases pre y poscirugía de revascularización. Se definieron como elementos esenciales la evaluación de síntomas y las funciones cognitiva, musculoesquelética y cardiorrespiratoria. En el preoperatorio, control del dolor, reducción de edemas, ganancia de amplitud de movimiento, deambulación y educación en salud son los objetivos; en la fase posoperatoria, la ganancia de fuerza muscular. Los ejercicios pasivos, asistidos, activos libres y circulatorios, incluidos los miembros superiores, se indican antes y después de las cirugías. La educación en salud y la deambulación con reducción de peso en el área de lesión plantar son esenciales en todo el período de internación. La electroanalgesia fue preconizada en el preoperatorio; y, en el postoperatorio, elevación del miembro inferior y ejercicios resistidos.

ABSTRACT Critical limb ischemia (CLI) is a disease with a great burden for the healthcare system, patient's functionality and quality of life. However, there is little evidence to guide intrahospital physical therapy programs for patients with CLI. Thus, this study aimed to provide an expert consensus on intrahospital physiotherapeutic care for CLI patients. An expert panel was made up with 18 experienced physical therapists, which represented 85.7% of physical therapists from a reference vascular surgery team in a university hospital. The Delphi method was used to produce a consensus, considering a minimum agreement of 70% and a mean or median score in the Likert scale ≥3.1. The questionnaires included items related to assessment, goals and physiotherapeutic interventions prior and after revascularization. A consensus was reached on assessing symptoms, cognitive, articular, musculoskeletal and cardiorespiratory functions. Pain control, edema drainage, range of motion gain, walking incentive and health education are goals in the pre-operatory and the muscular strengthening in postoperatory phase. In both phases there was a consensus on the use of passive, active-assisted and active exercises, including upper limb exercises. Walking and therapeutic education are essential during the hospitalization period with offloading practices in area of plantar ulcer. Electroanalgesia should be used in preoperative phase and resisted exercises and lower limb elevation at postoperatory.

Introdução: Lesões no terço distal dos membros inferiores, com exposição de ossos, articulações, tendões e vasos sanguíneos, não são passíveis do uso de enxertos de pele. Isto ocorre porque o leito vascular é exíguo e pela pobre granulação das feridas, podendo apenas ser corrigidas com retalhos musculares, miocutâneos, fasciocutâneos ou transferência microcirúrgica. Métodos: O retalho em seu limite inferior é demarcado a partir de 5 cm acima dos maléolos. Superiormente, é marcado num comprimento suficiente para cobertura total da lesão. Realizada incisão em demarcação prévia, e elevados pele e tecido subcutâneo juntamente com a fáscia muscular. O nervo sural é preservado em seu leito original. A elevação do retalho se dá até o ponto inferior marcado (o pedículo). Neste ponto, o retalho é transposto numa angulação suficiente para alcançar a lesão. Resultados: Oito casos foram operados utilizando o retalho descrito. Todos apresentavam exposição de ossos e tendões em região distal da perna, dorso do pé ou ambos, nos quais foram utilizados o retalho fasciocutâneo reverso da perna com a técnica proposta por Carriquiry. Os casos apresentaram resultados estético e funcional satisfatórios. Conclusão: O retalho utilizado se presta à correção de lesões do terço inferior da perna e do pé. É relativamente fácil de ser confeccionado, com bom suprimento vascular, e não há perda funcional do leito doador.

Introduction: Skin grafts are not effective to cover lesions in the distal third of the lower limbs that expose the bones, joints, tendons, and blood vessels due to a limited vascular bed and poor granulation of the wounds. These lesions can only be corrected with microsurgical transfer or muscle, myocutaneous, or fasciocutaneous flaps. Methods: The lower border of the flap was marked 5 cm above the malleolus. The upper border was marked after providing sufficient length for complete coverage of the lesion. The incision was performed at the marked upper border, and the skin and subcutaneous tissue were elevated together with muscle fascia. The sural nerve was preserved in its original bed. The flap was lifted to the marked lower border (the pedicle). At this point, the flap was transposed at a sufficient angle to cover the lesion. Results: Eight cases of surgery were conducted using the flap described above. All cases had exposed bones and tendons in the distal region of the limb, back of the foot, or both, in which the reverse sural fasciocutaneous flap with the technique proposed by Carriquiry was used. The cases showed satisfactory esthetic and functional results. Conclusion: The used flap can correct lesions of the lower third of the limbs and foot. It is relatively easy to make, with good vascular supply, and there is no functional loss of the donor area.

O objetivo foi estimar a carga da doença para as amputações de membros inferiores atribuíveis ao diabetes mellitus no Estado de Santa Catarina, Brasil, no período de 2008 a 2013. Realizou-se um estudo epidemiológico descritivo, utilizando-se o cálculo de anos de vida perdidos ajustados por incapacidade (DALY - disability-adjusted life years). A carga da doença foi alta, mais de 8 mil DALY, distribuídos entre homens e mulheres. A incapacidade respondeu por 93% do DALY e a mortalidade por 7,5%. A carga dos homens foi 5.580,6 DALY, praticamente o dobro das mulheres (2.894,8), sendo que a participação do componente anos de vida saudável perdidos em virtude de incapacidade (YLD - years lost due to disability) dos homens impulsionou esta taxa para 67,6% do total do DALY. Os homens vivem mais tempo com a amputação, por isto perdem mais anos de vida sadia (65,8%), e a mortalidade é maior entre as mulheres (61%). As distribuições das taxas de DALY no estado não mostraram distribuição homogênea. A intensificação de avaliação, planejamento e desenvolvimento de estratégias custo-efetivas para a prevenção e educação em saúde para o pé diabético deve ser considera a partir da maior vulnerabilidade masculina.

El objetivo fue estimar la carga de enfermedad para las amputaciones de miembros inferiores, atribuibles a la diabetes mellitus en el Estado de Santa Catarina, Brasil, durante el período de 2008 a 2013. Se realizó un estudio epidemiológico descriptivo, utilizándose el cálculo de años de vida ajustados por discapacidad (DALY - disability-adjusted life years). La carga de la enfermedad fue alta, más de 8 mil DALY distribuidos entre hombres y mujeres. La incapacidad supuso un 93% del DALY y la mortalidad un 7,5%. La carga de los hombres fue 5.580,6 DALY, prácticamente el doble de las mujeres (2.894,8), siendo que la participación del componente años de vida saludable perdidos por discapacidad (YLD - years lost due to disability) de los hombres impulsó esta tasa hacia un 67,6% del total del DALY. Los hombres viven más tiempo con la amputación, por ello pierden más años de vida sana (65,8%), y la mortalidad es mayor entre las mujeres (61%). Las distribuciones de las tasas de DALY en el estado no mostraron distribución homogénea. La intensificación de evaluación, planificación y desarrollo de estrategias costo-efectivas para la prevención y educación en salud para el pie diabético debe ser considerada a partir de la mayor vulnerabilidad masculina

The objective was to estimate the burden of disease from lower limb amputations attributable to diabetes mellitus in Santa Catarina State, Brazil, from 2008 to 2013. A descriptive epidemiological study was performed by calculating disability-adjusted life years (DALY). Burden of disease was high, more than 8,000 DALY in men and women. Disability accounted for 93% of DALY and mortality for 7.5%. The burden in men was 5,580.6 DALY, almost double that in women (2,894.8), and the share of the years lost due to disability (YLD) component in men pushed this rate to 67.6% of total DALY. Men live longer following amputation, so they lose more years of healthy life (65.8%), while mortality is higher in women (61%). DALY rates were not distributed homogeneously across the state. The intensification of evaluation, planning, and development of cost-effective strategies for prevention and health education for diabetic foot should be oriented according to higher male vulnerability.

The imbalance between bone formation and osteolysis plays a key role in the pathogenesis of aseptic loosening. Strontium ranelate (SR) can promote bone formation and inhibit osteolysis. The aim of this study was to explore the role and mechanism of SR in aseptic loosening induced by wear particles. Twenty wild-type (WT) female C57BL/6j mice and 20 sclerostin-/- female C57BL/6j mice were used in this study. Mice were randomly divided into four groups: WT control group, WT SR group, knockout (KO) control group, and KO SR group. We found that SR enhanced the secretion of osteocalcin (0.72±0.007 in WT control group, 0.98±0.010 in WT SR group, P=0.000), Runx2 (0.34±0.005 in WT control group, 0.47±0.010 in WT SR group, P=0.000), β-catenin (1.04±0.05 in WT control group, 1.22±0.02 in WT SR group, P=0.000), and osteoprotegerin (OPG) (0.59±0.03 in WT control group, 0.90±0.02 in WT SR group, P=0.000). SR significantly decreased the level of receptor activator for nuclear factor-κB ligand (RANKL) (1.78±0.08 in WT control group, 1.37±0.06 in WT SR group, P=0.000) and improved the protein ratio of OPG/RANKL, but these effects were not observed in sclerostin-/- mice. Our findings demonstrated that SR enhanced bone formation and inhibited bone resorption in a wear particle-mediated osteolysis model in wild-type mice, and this effect relied mainly on the down-regulation of sclerostin levels to ameliorate the inhibition of the canonical Wnt pathway.

ABSTRACT Objectives: to evaluate the epidemiological profile, the surgical treatment and the postoperative results of patients with complex traumatic injuries to the lower limbs. Methods: we conducted a retrospective study of patients with traumatic complex injuries treated by the Plastic Surgery Service of a regional hospital in Brasília. We analyzed clinical-epidemiological data, type of surgical procedure and functional recovery of the limb after six months of treatment. Results: 119 patients were treated, with a mean age of 29 years, predominantly men (76.4%). Motorcycle accident was responsible for most of the injuries, in 37.8% of cases. The most frequent surgical treatment was skin grafting (62.1%), followed by the fasciocutaneous flap (21.9%), muscular flap (12.6%) and microsurgical flap (3.4%). Six months after completion of the surgical treatment, 35.3% of the patients needed crutches to move, characterizing a delay in limb functional recovery that, however, was significantly related to the presence of fractures, external fixation or bone exposure in the preoperative period. Conclusion: the profile of the patient with complex traumatic lower limb injury was a male, motorcycle accident victim, and grafting was the most used treatment. Orthopedic trauma with bone fracture, bone exposure and the presence of external fixator were significantly associated with a higher risk of limb functional impairment, requiring locomotion crutches after six months of treatment.

RESUMO Objetivo: avaliar o perfil epidemiológico, o tratamento cirúrgico e os resultados pós-operatórios de pacientes com feridas complexas traumáticas de membros inferiores. Método: estudo retrospectivo dos pacientes com ferimentos complexos traumáticos tratados pelo Serviço de Cirurgia Plástica de um hospital regional de Brasília. Foram analisados os dados clínico-epidemiológicos, o tipo de procedimento cirúrgico e a recuperação funcional do membro após seis meses do tratamento. Resultados: foram tratados 119 pacientes, com média de idade de 29 anos, predominantemente homens (76,4%). O acidente moto ciclístico foi responsável pela maioria das lesões, em 37,8% dos casos. O tratamento cirúrgico mais realizado foi o enxerto de pele (62,1% dos casos), seguido pelo retalho fascio-cutâneo (21,9%), o retalho muscular (12,6%) e o retalho microcirúrgico (3,4%). Seis meses após a conclusão do tratamento cirúrgico, 35,3% dos pacientes necessitavam de muletas para se locomover, caracterizando um atraso na recuperação funcional do membro que, no entanto, estava relacionado significativamente à presença de fratura, de fixador externo ou de exposição óssea no pré-operatório. Conclusão: o perfil do paciente com ferida complexa traumática de membros inferiores foi homem, vítima de acidente motociclístico e o enxerto foi o tratamento mais utilizado. O trauma ortopédico com fratura óssea, exposição óssea e a presença de fixador externo estiveram associados significativamente a um maior risco de prejuízo funcional do membro com necessidade de muletas para locomoção após seis meses de tratamento.

Contexto: Úlceras são a resultante final de varizes associadas a refluxo de veias safenas. Objetivo: Demonstrar a possibilidade de associar dois procedimentos, a escleroterapia com espuma de veias safenas e o enxerto de pele parcial, para o tratamento de pacientes com úlceras venosas relacionadas a refluxo de veias safenas. Métodos: Foram tratados 20 membros em 20 pacientes, todos com ulcerações relacionadas a refluxo de veias safenas. Realizamos o enxerto de pele expandida, seguido da escleroterapia ecoguiada com espuma de polidocanol nas veias associadas às úlceras, através de punção ou dissecção da veia. Resultados: Em todos os casos, houve melhora dos sintomas relacionados à úlcera e cicatrização da lesão. Em 11 casos, obtivemos a viabilidade do enxerto de pele por completo; em quatro casos, houve cicatrização de cerca de 50% da lesão; e nos cinco casos restantes, houve cicatrização de aproximadamente 75% da lesão. A primeira ultrassonografia de controle revelou esclerose completa dos vasos tratados em 19 dos 20 casos e esclerose parcial sem refluxo detectável em um caso. Na segunda ultrassonografia, realizada após 45 dias, observamos esclerose completa de 15 casos; em cinco casos, houve esclerose parcial, dos quais três sem refluxo detectável e dois com refluxo em segmentos isolados associados a varizes. A complicação mais frequente foi a pigmentação nos trajetos venosos, observada em 13 pacientes. Um caso apresentou trombose assintomática de veias musculares da perna. Conclusão: Essa associação de procedimentos consiste em uma opção válida com potencial para promover um tratamento mais breve e de menor custo

Background: Ulcers are the end result of varicose veins associated with reflux in saphenous veins. Objective: To demonstrate the possibility of combining two procedures, foam sclerotherapy of saphenous veins and skin grafting, to treat patients with venous ulcers related to reflux in saphenous vein. Methods: 20 limbs were treated in 20 patients. All patients had ulcers related to saphenous vein reflux. We performed the grafting with expanded skin, followed by administration of ultrasound guided polidocanol foam sclerotherapy in veins associated with ulcers, accessed by puncture or dissection of the vein. Results: In all cases there was improvement of ulcer-related symptoms and healing of the lesion. In 11 cases we achieved full skin grafting viability. In four cases there was healing of about 50% of the lesion and in the other five cases approximately 75% of the lesion healed. The first control ultrasonographic examination revealed complete sclerosis of the vessels treated in 19 of 20 cases, with partial sclerosis in one case, but no detectable reflux. The second ultrasonographic examination performed at 45 days showed complete sclerosis in 15 cases. In five cases there was partial sclerosis, without detectable reflux in three and with reflux in isolated segments associated with varicose veins in two. The most common complication was pigmentation along vein paths, observed in 13 patients. In one case there was asymptomatic thrombosis of muscle veins of the leg. Conclusion: This combination of procedures is a valid option, with the potential to provide quicker and less expensive treatment

OBJETIVO: Evaluar los resultados de alargamiento óseo sobre clavo endomedular (LON) en extremidades inferiores; comparar resultados locales con la literatura. MATERIAL Y MÉTODO: Estudio retrospectivo de pacientes operados con LON entre los años 2011 y 2015, con información de ficha clínica e imagenología. Descripción del paciente, procedimiento y evolución; con cálculo del Índice de Consolidación Radiológica (RCI) e Índice de Fijación Externa (EFI). Comparación con la literatura. RESULTADOS: Se reunieron 8 pacientes, con 12 procedimientos LON. 4 pacientes tuvieron alargamiento bilateral por talla baja constitucional y 4 pacientes tuvieron alargamiento unilateral por defectos de longitud, congénitos o adquiridos. En fémur (6) el alargamiento promedio fue 51 mm con 134 días de uso de tutor externo. El EFI promedio fue 0,87 meses/centímetro y RCI 1.83 meses/centímetro. En tibia (4) el alargamiento promedio fue 82 mm con 121 días de uso de tutor externo. El EFI promedio fue 0,49 meses/centímetro y RCI 1.64 meses/ centímetro. Todos los pacientes presentaron infección superficial de pines, requiriendo antibioterapia oral. 4 pacientes con LON de tibia presentaron contractura en equino y requirieron de alargamiento aquiliano percutáneo. 3 pacientes con LON de fémur presentaron retardo de consolidación, 2 requirieron aporte de injerto óseo. DISCUSIÓN: El LON es una excelente alternativa a los métodos tradicionales de alargamiento, con tiempos más cortos de uso de tutor externo. Se observan complicaciones relacionadas con la contractura músculo-tendinosa, manejadas al momento del retiro de tutor externo, con resultados satisfactorios para el paciente.

OBJECTIVE: To evaluate the results of bone lengthening over an intramedullay nail (LON) in lower limbs and compare our results with the literature. MATERIAL AND METHODS: retrospective study of patients who underwent LON between may 2011 and June 2015. The information was collected from clinical charts and Radiological studies. Description of the demographic data, procedures performed and follow up were registered. ; calculation of radiological consolidation index (RCI) and of external fixation index (EFI), previously defined in the literature, was performed. RESULTS: A total of 8 patients, with 12 LON procedures were included. 4 patients had bilateral lengthening for constitutional short stature and 4 patients had unilateral Lengthening for congenital or acquired defects. On femur (6), the average Lengthening was 51 mm. Mean time on external fixator was 134 days. The average EFI was 0.87 months/cm and RCI 1.83 months/cm. On tibia (4) the mean lengthening was 82 mm, and external fixator time was 121 days. The average EFI was 0.49 months/cm and RCI 1.64 months/cm. All patients had at least one superficial pin site infection, requiring oral antibiotic therapy. 4 patients whitin tibia group had an Equinus Contracture that required percutaneous Achilles lengthening. 3 patients whitin femoral group developed delayed bone healing and 2 of them required bone grafting on the distraction site. DISCUSSION: LON is an excellent alternative to traditional methods of lengthening, with shorter times under external fixator. There are complications related to tendon and muscle contracture, handled at the time of removal of external fixator, with satisfactory results for the patient.
