[Clinical and functional evaluation of pediatric patients with pelvic fracture treated in a third level Hospital]. / Evaluación clínica y funcional de pacientes pediátricos con fractura de pelvis tratados en un Hospital de Tercer Nivel.

INTRODUCTION: pelvic fracture in children is considered one of the most important injuries due to its high mortality. They are rare, but have a major impact on patients' functional outcomes. OBJECTIVE: to evaluate the clinical evolution and functional grade in pediatric patients with pelvic fractures who have already been treated, either conservatively or surgically. MATERIAL AND METHODS: descriptive-cross-sectional-retrospective study. Sample of 24 patients, aged five to 16 years with pelvic fracture, treated from 2016 to 2021. Clinical and functional outcome was assessed using the Barthel index and hip range of motion, as well as surgical or conservative treatment, accompanying lesions and injury mechanism. RESULTS: to find out if there is an association between the Torode and Zieg classifications with the Barthel index and hip range of motion, an association analysis was performed with the 2 statistic, obtaining a 2 value = 19.213. with p = 0.004 for the Barthel index and a 2= 14.253 with p = 0.0026 for hip ranges of motion; these results indicate that there is statistically significant association. CONCLUSION: the most frequent type of pelvic fracture in pediatric patients treated is type III on the Torode and Zieg scale, which according to the Barthel index is associated with a degree of independence and complete hip mobility arches, so the clinical and functional outcome in these patients is high in severe injuries.

INTRODUCCIÓN: la fractura de pelvis en edad pediátrica es considerada de las lesiones más importantes debido a su alta mortalidad; son poco frecuentes, pero tienen gran impacto en el resultado funcional de los pacientes. OBJETIVO: evaluar la evolución clínica y grado funcional en niños con fracturas de pelvis tratados de forma conservadora o quirúrgica. MATERIAL Y MÉTODOS: estudio descriptivo-transversal-retrospectivo. Muestra de 24 pacientes, de cinco a 16 años de edad, con fractura de pelvis, tratados del 2016 al 2021. Se valoró el resultado clínico y funcional mediante el índice de Barthel y arcos de movilidad de cadera, tratamiento quirúrgico o conservador, lesiones acompañantes y mecanismo de lesión. El análisis estadístico se realizó con el software IBM SPSS Statistics®. RESULTADOS: se realizó un análisis de asociación mediante 2 entre las clasificaciones de Torode y Zieg con el índice de Barthel y arcos de movilidad de cadera, obteniendo un valor de 2 = 19.213 con p = 0.004 para índice de Barthel y un valor de 2= 14.253 con p = 0.0026 para arcos de movilidad de cadera; estos resultados indican que hay una asociación estadísticamente significativa. CONCLUSIÓN: el tipo de fractura de pelvis más frecuente en pacientes tratados es el tipo III en la escala de Torode y Zieg, la cual, según el índice de Barthel, se asocia con un grado de independencia y arcos de movilidad de cadera completos, por lo que el resultado clínico y funcional en estos pacientes es alto en lesiones severas.

Falls among older adults in the South of Brazil: prevalence and determinants.

OBJECTIVE Evaluate the prevalence and the factors associated with the occurrence of falls among older adults. METHODS A cross-sectional study with a representative sample of 1,451 elderly residents in the urban area of Pelotas, RS, in 2014. A descriptive analysis of the data was performed and the prevalence of falls in the last year was presented. The analysis of demographic, socioeconomic, behavioral and health factors associated with the outcome was performed using Poisson regression with adjustment for robust variance according to the hierarchical model. The variables were adjusted to each other within each level and for the higher level. Those with p ≤ 0.20 were maintained in the model for confounding control and those with p < 0.05 were considered to be associated with the outcome. RESULTS The prevalence of falls among older adults in the last year was 28.1% (95%CI 25.9-30.5), and most occurred in the person's own residence. Among the older adults who fell, 51.5% (95%CI 46.6-56.4) had a single fall and 12.1% (95%CI 8.9-15.3) had a fracture as a consequence, usually in the lower limbs. The prevalence of falls was higher in women, adults of advanced age, with lower income and schooling level, with functional incapacity for instrumental activities, and patients with diseases such as diabetes, heart disease, and arthritis. CONCLUSIONS The occurrence of falls reached almost a third of the older adults, and the prevalence was higher in specific segments of the population in question. About 12% of the older adults who fell fractured some bone. The factors associated with the occurrence of falls identified in this study may guide measures aimed at prevention in the older adult population.

RESUMO OBJETIVO Avaliar a prevalência e os fatores associados à ocorrência de quedas em idosos. MÉTODOS Estudo transversal com amostra representativa de 1.451 idosos residentes na zona urbana de Pelotas, RS, em 2014. Foi realizada análise descritiva dos dados e apresentada a prevalência de quedas no último ano. A análise de fatores demográficos, socioeconômicos, comportamentais e de saúde associados ao desfecho foi realizada por meio de regressão de Poisson com ajuste para variância robusta conforme modelo hierárquico. As variáveis foram ajustadas entre si dentro de cada nível e para as de nível superior. Aquelas com p ≤ 0,20 foram mantidas no modelo para controle de confusão e aquelas com p < 0,05 foram consideradas associadas ao desfecho. RESULTADOS A prevalência de quedas em idosos no último ano foi de 28,1% (IC95% 25,9-30,5), e a maioria ocorreu na própria residência do idoso. Entre os idosos que sofreram queda, 51,5% (IC95% 46,6-56,4) tiveram uma única queda e 12,1% (IC95% 8,9-15,3) tiveram fratura como consequência, sendo a de membros inferiores a mais relatada. A prevalência de quedas foi maior em mulheres, idosos com idade avançada, de menor renda e escolaridade, com incapacidade funcional para atividades instrumentais e portadores de enfermidades como diabetes, doença cardíaca e artrite. CONCLUSÕES A ocorrência de quedas atingiu quase um terço dos idosos, e a prevalência foi mais elevada em segmentos específicos da população em questão. Cerca de 12% dos idosos que caíram, fraturaram algum osso. Os fatores associados à ocorrência de quedas identificados neste estudo poderão nortear medidas que visem sua prevenção na população de idosos.

Analysis of Musculoskeletal Injuries Sustained in Falls From the United States-Mexico Border Fence.

Injuries sustained by unauthorized individuals who jump or fall from the United States-Mexico border fence are frequently treated by trauma centers in border states. The authors investigated patterns of musculoskeletal injury occurring in these individuals to improve emergency department assessment and to identify strategies to prevent future injuries. A retrospective chart review was performed for patients presenting to an urban, level I trauma center with musculoskeletal injuries sustained in a jump or fall from the United States-Mexico border fence between February 2004 and February 2010. Frequency of fracture by site, frequency of open fracture, and associated patterns of injury were recorded. The population was stratified by age and sex to identify disparity in injury pattern. Average length of stay and number of surgical interventions were also recorded. During the study period, 174 individuals who had jumped or fallen from the United States-Mexico border fence were identified. The population contained 93 (53%) women and 81 (47%) men with an average age of 31.5 years (range, 11-56 years). On average (±standard error), men sustained slightly more fractures than women (1.77±0.12 vs 1.43±0.07; P=.015). There were no significant differences in the number of fractures sustained between age groups. Average length of stay for patients admitted to the hospital was 3.5 days. Patients underwent an average of 0.75 surgical interventions during admission. Falls from the United States-Mexico border fence are a significant cause of morbidity among unauthorized immigrants.

Concordância intra e interobservadores do sistema de classificação AO para fraturas dos ossos longos na população pediátrica / Intra and interobserver concordance of the AO classification system for fractures of the long bones in the pediatric population

A classificação AO para fraturas dos ossos longos na população pediátrica foi desen volvida e validada em 2006. Entretanto, a complexidade desse sistema tem limitado o seu uso na prática clínica. Poucos estudos na literatura avaliam sua reprodutibilidade e aplicabi lidade. Este trabalho teve como objetivo determinar a concordância intra e interobservadores com o uso do sistema de classificação AO pediátrica entre médicos de diferentes níveis de experiência. Métodos: Após a feitura do cálculo amostral, foram selecionadas 108 radiografias consecuti vas de fraturas de ossos longos de pacientes de 0-16 anos, provenientes do arquivo digital de um hospital de nível quaternário. As radiografias foram classificadas por cinco examina dores com diferentes níveis de experiência após uma explicação prévia sobre o sistema. Foi mostrada uma planilha que continha as imagens da classificação para consulta. As avaliações foram feitas em dois momentos distintos por cada observador. O índice Kappa de Fleiss foi usado para verificar a concordância intra e interobservadores. Resultados: Foram obtidas concordâncias intraobservadores no mínimo substanciais em todos os itens da classificação, alcançaram níveis excelentes por todos os observadores em cinco dos sete itens considerados. A avaliação interobservadores apresentou níveis de concordância excelentes em dois itens, substancial em dois itens, moderada a substancial em um item e pobre a moderada em um dos itens. Não se observou influência da experi ência do observador na obtenção de maiores ou menores níveis de concordância, intra ou interobservadores. Conclusões: Neste estudo, a concordância intra e interobservadores foi considerada boa ou excelente para o sistema de classificação AO pediátrico para os parâmetros: osso, seg mento, osso pareado, subsegmento, padrão e desvio. No entanto, a concordância intra e interobservadores foi estatisticamente insatisfatória no parâmetro gravidade/lado da avulsão. Os níveis de concordância obtidos independem da experiência do observador em ortopedia pediátrica.

The AO classification for fractures of the long bones in the pediatric population was developed and validated in 2006. However, the complexity of this system has limited its use in clinical practice and few studies in the literature have evaluated its reproducibility and applicability. The present study had the objective of determining the intra and interobserver agreement using the pediatric AO system, among physicians with different levels of experience. METHODS: After making the sample calculation, 108 consecutive radiographs on long-bone fractures in patients aged 0-16 years, coming from the digital files of the quaternary-level hospital, were selected. The radiographs were classified by five examiners with different levels of experience after prior explanations about the system. A chart containing images from the classification was made available for consultation. The evaluations were made at two different times by each observer. The Fleiss kappa index was used to ascertain the intra and interobserver agreement. RESULTS: Intraobserver agreement that was at least substantial was obtained for all the items of the classification and it reached excellent levels for all observers in relation to five of the seven items considered. The interobserver evaluation presented excellent levels of agreement in two items, substantial in two items, moderate to substantial in one item and poor to moderate in one item. No influence from the observer's experience was observed with regard to obtaining higher or lower levels of agreement, either in the intraobserver or in the interobserver evaluation. CONCLUSIONS: In this study, the intra and interobserver agreement was considered to be good or excellent for the pediatric AO classification system, for the parameters of bone, segment, paired bone, subsegment, standard and deviation. However, the intra and interobserver agreement was statistically unsatisfactory for the parameter of severity/side of avulsion. The levels of agreement obtained did not depend on the observer's level of experience within pediatric orthopedics.

Classification of pelvic ring fractures in skeletonized human remains.

Pelvic ring fractures are associated with high rates of mortality and thus can provide key information about circumstances surrounding death. These injuries can be particularly informative in skeletonized remains, yet difficult to diagnose and interpret. This study adapted a clinical system of classifying pelvic ring fractures according to their resultant degree of pelvic stability for application to gross human skeletal remains. The modified Tile criteria were applied to the skeletal remains of 22 individuals from the Cleveland Museum of Natural History and Universidad Nacional Autónoma de México that displayed evidence of pelvic injury. Because these categories are tied directly to clinical assessments concerning the severity and treatment of injuries, this approach can aid in the identification of manner and cause of death, as well as interpretations of possible mechanisms of injury, such as those typical in car-to-pedestrian and motor vehicle accidents.

Objective: To assess the functional results of patients who sustained Neer III-IV shoulder fractures treated with hemiarthroplasty. Material and methods: Descriptive, ambispective, cross-sectional study. From January to December 2011 patient records were reviewed, a functional assessment was performed using the Constant scale, and the DASH questionnaire was applied. Data was analyzed with the SPSS software, descriptive statistics and frequency analysis. Results: Sixteen patients were evaluated, mean age was 60.9 years (p = 0.004); females represented 56.3% (p = 0.001). The mechanism of injury was low energy trauma in 93.8%. According to the Constant scale, whose maximum score is 100, the score of our population was 40.75 (± 14.42). The highest prevalence rates corresponded to: middle pain, 8 (50%); work with full performance, 7 (43.75%); painful range of motion up to the xyphoid process (37.5%). Ranges of motion were as follows: abduction 30-60º 10 (62.5% p = 0.004), flexion 30-60º 6 (37.5%), external rotation, 14 (87.5%) with the hand behind the head, internal rotation up to the lumbosacral region, 7 (43.75% p = 0.005). Power of up to 3 kilograms, 5 (31.3% p = 0.005). Poor results were seen in 13 (81.3%) patients. The DASH questionnaire results were: disability/symptoms, 12 (75%) and special activities, 7 (43.75%) good results; in the work module, 8 (50%) fair results. Satisfaction with the surgical procedure, 87.5 percent. Conclusions: In this patient sample the function of the operated shoulder was considered as poor according to the Constant scale; it was good considering the symptoms and special activities, and fair for the work module, according to the DASH questionnaire.

Assessment of pelvic fractures resulting from the 2010 Haiti earthquake: opportunities for improved care.

BACKGROUND: On January 12, 2010, a catastrophic 7.0 magnitude earthquake shook the Haitian capital of Port-au-Prince. Because of their sudden and destructive nature, earthquakes can result in unfamiliar mass casualty situations accompanied by devastating orthopedic injuries. Evaluation of the pelvic fractures resulting from this earthquake revealed several factors that we hope will facilitate optimal preparation and planning for future disaster situations. METHODS: A cohort of patients with earthquake-related pelvic ring fractures who were treated aboard the USNS Comfort was retrospectively analyzed. Anteroposterior radiographs of the pelvis were evaluated and categorized according to the Young-Burgess classification system. RESULTS: Sixty-eight patients were included in the cohort. The mean (SD) age was 29.6 (14.4) years. Nineteen patients (29.7%) were male, and 49 (70.3%) were female. Pelvic fractures were categorized as anteroposterior compression in 7 patients, lateral compression (LC) in 47 patients, vertical shear (VS) in 8 patients, and combination of pelvic ring/acetabulum in 6 patients. Among the 23 patients treated operatively, the mean (SD) delay from injury to surgery was 19.2 (7.4) days. CONCLUSION: Patients showed predominance toward LC injuries (69.1%), consistent with crush under rubble. Thirty-one percent of the fractures were considered unstable (anteroposterior compression Type III, LC Type III, VS, and combination of pelvic ring/acetabulum). The VS injuries observed (11.8%) may be the result of a previously unidentified injury mechanism, an upright individual being struck by falling rubble, violently applying a downward force to the body over an extended lower extremity. A substantial delay in the treatment observed in this series may lead to an underestimation of both quantity and severity of pelvic fractures as critically ill patients may have perished before evaluation and treatment. In addition, the application of pelvic sheeting techniques may be a lifesaving intervention for interval pelvic stabilization following earthquakes in which medical resources are scarce. LEVEL OF EVIDENCE: Epidemiologic study, level III; therapeutic study, level V.

Rodilla flotante: nuestra experiencia / Floating knee. Our experience

Se denomina rodilla flotante a una combinación de fracturas diafisarias, metafisarias e intraarticulares de fémur y de tibia ipsilateral, entre la zona subtroncantérica femoral y la zona diafisaria de la tibia. Se presentan con mayor frecuencia en pacientes politraumatizados que ingresan al hospital hemodinámicamente descompensados y requieren un cuidadoso control y seguimiento durante la atención primaria de acuerdo al protocolo del ATLS. Se realizó un estudio retrospectivo de 38 pacientes con "lesión de rodilla flotante" ingresados y tratados en el Servicio de Traumatología y Ortopedia del Hospital Municipal de Urgencias, con un seguimiento mínimo de 5 meses. La edad promedio de nuestros pacientes fue de 29 años. La media de internación 20 días. Se estadificó las lesiones según la clasificación de Fraser. El manejo inicial de estos pacientes se realizó con tracción esquelética, yesos o colocación de tutor externo. Para la estabilización definitiva de estas lesiones se realizó un análisis pormenorizado de cada caso en particular y sus lesiones asociadas, lo que determinó las variantes de tratamiento. La estabilización inicial es precaria y no mejora el pronóstico, la rehabilitación temprana ni la reintegración del paciente a su medio biopsicosocial; pero nos permite obtener un resultado final aceptable comparable con las series publicadas.(AU)

Desenho de placa em forma de borboleta para tratamento de fraturas do calcâneo / Design of butterfly-shaped plate and its application in treatment for calcaneal fractures

OBJETIVO: Apresentar um desenho de placa em forma de borboleta e sua aplicação no tratamento de fraturas do calcâneo e discutir suas indicações clínicas, vantagens e desvantagens. MÉTODOS: De fevereiro de 2008 a abril de 2010, 22 pacientes com 26 fraturas intra-articulares do calcâneo foram tratados com redução a céu aberto e fixação interna com placa em forma de borboleta. Dezesseis pacientes eram homens e 6 eram mulheres, com média de idade de 36,8 anos. Onze eram pés esquerdos e 15, direitos. De acordo com a classificação de Sanders, 12 eram fraturas de calcâneo Tipo II (inclusive 3 Tipo IIa, 7 Tipo IIb e 2 Tipo IIc) e 14 eram Tipo III (inclusive cinco do Tipo IIIab, 7 Tipo IIIac e duas do Tipo IIIbc). RESULTADOS: Dezessete pacientes (21 pés) foram submetidos a acompanhamento por em média 19,2 meses. Os desfechos funcionais foram avaliados com o sistema Maryland Foot Score. Entre os nove pés com fraturas Tipo II, sete receberam escore excelente e dois, bom. Entre as 12 fraturas Tipo III, seis tiveram escore excelente, cinco, bom e uma, razoável. CONCLUSÃO: A placa em forma de borboleta é aplicável ao tratamento de fraturas do calcâneo do Tipo II e Tipo III de Sanders, com a vantagem de garantir fixação confiável, facilitar a cirurgia, produzir menos complicações pós-operatórias e produzir melhores desfechos clínicos gerais. Nível de Evidência IV, Série de casos.

OBJECTIVE: To introduce the design of butterfly-shaped plate and its application in treatment for calcaneal fractures, and to discuss its clinical indications, advantages and disadvantages. METHODS: From February 2008 to April 2010, 22 patients with 26 intra-articular calcaneal fractures were treated by open reduction and internal fixation with butterfly-shape plate. Sixteen patients were male and 6 patients were female, with a mean age of 36.8 years. Eleven were left feet and 15, right. According to Sanders classification, 12 were Type II (including 3 Type IIa, 7 Type IIb and 2 Type IIc) and 14 were Type III (including 5 Type IIIab, 7 Type IIIac and 2 Type IIIbc). RESULTS: Seventeen patients (21 feet) were followed-up for an average of 19.2 months. The functional outcomes were assessed using the Maryland Foot Score system. Among the 9 feet with Type II fractures, 7 feet were scored excellent, 2 were good. Among the 12 Type III fractures, 6 were scored excellent, 5 were good, and one was fair. CONCLUSION: The butterfly-shaped plate is applicable to treatment for Sanders Type II and Type III calcaneal fractures, with advantages of ensuring reliable fixation, easier operation, fewer post-operative complications, and better clinical outcomes.

MÉTODO: Revisamos retrospectivamente os resultados clínicos de 48 casos de fraturas subtrocantéricas tratadas com placas de bloqueio lateral da parte proximal do fêmur de janeiro de 2008 a maio de 2010. Registrou-se o progresso da consolidação da fratura, assim como a ocorrência de complicações. A função da articulação do quadril foi avaliada pelo índice social de Harris e o escore de mobilidade de Parker-Palmer, um ano após a cirurgia. RESULTADO: Quarenta e cinco pacientes foram acompanhados até a união da fratura ou a revisão da cirurgia. Entre os 45 pacientes, 43 atingiram a união da fratura sem outra intervenção. Trinta e oito fraturas consolidaram sem perda da posição no acompanhamento de um ano. Não houve casos de perfuração da cabeça do fêmur pelo parafuso. O escore médio do índice social de Harris foi 86,5 ± 9,8 (73 ~95). A média do escore de mobilidade de Parker e Palmer foi 7,4 ± 2,1 (3~ 9). CONCLUSÃO: A placa de bloqueio lateral da parte proximal do fêmur é o tipo de fixação interna estável e efetiva para tratar as fraturas subtrocantéricas de quadril e tem a vantagem de fixação estável, em especial em fratura da parede lateral do fêmur.

OBJECTIVE: To study the outcome of subtrochanteric hip fractures treated by using a proximal lateral femur locking plate. METHOD: We retrospectively reviewed the clinical results of 48 cases of femoral subtrochanteric fractures treated with proximal lateral femur locking plates from Jan 2008 to May 2010. The progress of fracture healing, as well as the occurrence of complications, was recorded. The function of the hip joint was evaluated by Harris social index and the Parker and Palmer mobility score at 1 year after the operation. RESULT: 45 patients were followed up until fracture union or a revision surgery. Among the 45 patients, 43 patients obtained fracture union without further intervention. 38 fractures healed with no loss of position at the 1-year follow-up. There were no cases of hip screw cutting through the femoral head. The mean score of Harris social index was 86.5±9.8 (73~95). The mean Parker and Palmer mobility score was 7.4±2.1 (3~9). CONCLUSION: The proximal lateral femur locking plate is the kind of stable and effective internal fixation of treating subtrochanteric hip fractures which has the advantage of stable fixation especially for the lateral femoral wall fracture.

One-year mortality among elderly people after hospitalization due to fall-related fractures: comparison with a control group of matched elderly.

Fall-related fractures among the elderly represent an important public health problem. Severe fractures have been related to increased risk of death. In order to investigate the mortality profile of elderly individuals with severe fractures, 250 patients aged 60 years and over, hospitalized due to fall-related fractures and 250 elderly without fractures living in the local community were followed-up for one year. They were matched according to sex, age, time of hospitalization and neighborhood. Deaths were identified using probabilistic linkage of the research dataset and the local mortality registry. The one-year cumulative mortality was 25.2% in the case of individuals with severe fractures and 4% for those individuals without. The mortality distribution was not homogeneous across the follow-up period. Two-thirds of deaths among the elderly individuals hospitalized due to fracture occurred within the first 3 months, whereas mortality among those individuals without fractures took place later. Heart disease, pneumonia, GI bleeding, sepsis, and pulmonary embolism, diabetes and stroke were important causes of one-year mortality.

One-year mortality among elderly people after hospitalization due to fall-related fractures: comparison with a control group of matched elderly / Mortalidade em um ano de idosos após hospitalização por fratura decorrente de queda: comparação com idosos pareados da população

Fraturas decorrentes de queda entre idosos são um importante problema de saúde pública. Fraturas graves têm sido associadas com o maior risco de morte. Para investigar o perfil de mortalidade de idosos que sofreram fraturas graves, 250 indivíduos com 60 anos ou mais, hospitalizados devido à fratura decorrente de queda, e 250 idosos da população foram acompanhados por um ano. Esses grupos foram pareados por idade, sexo, momento da hospitalização do caso e vizinhança. Os óbitos foram identificados por meio do relacionamento probabilístico do banco de dados do estudo com a base de dados de mortalidade do estado. A mortalidade acumulada em um ano foi de 25,2% e 4% para idosos com e sem fratura grave, respectivamente. A distribuição dos óbitos não foi homogênea ao longo do tempo de seguimento. Dois terços das mortes entre paciente ocorreram no 1º trimestre após a fratura, enquanto que entre os controles os óbitos foram mais tardios. Doença cardíaca, pneumonia, sangramento digestivo, septicemia, embolia pulmonar, diabetes e AVE foram causas importantes de morte no ano que se seguiu à fratura.
