Evaluation of Intra- and Interobserver Reproducibility of the New AO/OTA Classification for Distal Radius Fractures Compared with the Fernandez Classification.

Objective To evaluate the inter- and intraobserver reliability and reproducibility of the new AO/OTA 2018 classification for distal radius fractures and to compare it with the Fernandez classification system. Method A questionnaire was applied in the Qualtrics software on 10 specialists in hand surgery who classified 50 radiographs of distal radius fractures according to the Fernandez and AO/OTA 2018 classifications and, subsequently, indicated their treatment. The questionnaire was applied in time T0 and repeated after 4 weeks (t1) . The mean agreement between the answers, and the reliability and inter- and intraobserver reproducibility were analyzed using kappa indexes. Results The mean interobserver agreement in the Fernandez classification was 76.4, and it was 59.2% in the AO/OTA 2018 classification. The intraobserver agreements were 77.3 and 56.6%, respectively. The inter- and intraobserver kappa indexes for the Fernandez classification were 0.57 and 0.55, respectively, and, in the AO/OTA 2018 classification, they were 0.34 and 0.31, respectively. Conclusion The AO/OTA 2018 classification showed a low intra- and interobserver reproducibility when compared with the Fernandez classification. However, both classifications have low intra- and interobserver indexes. Although the Fernandez classification did not obtain excellent results, it remains with better agreement for routine use.

Resumo Objetivo Avaliar a confiabilidade e a reprodutibilidade inter- e intraobservadores da nova classificação AO/OTA 2018 para fraturas distais do rádio e compará-la com o sistema classificatório de Fernandez. Métodos Foi aplicado um questionário no software Qualtrics em 10 especialistas em cirurgia da mão que classificaram 50 radiografias de fraturas distais de rádio de acordo com as classificações de Fernandez e AO/OTA 2018 e, posteriormente, indicaram seu tratamento. Esse questionário foi aplicado em tempo T0 e repetido após 4 semanas (t1). Analisou-se a média de concordância entre as respostas e confiabilidade e reprodutibilidade inter- e intraobservadores utilizando os índices kappa. Resultados A concordância média interobservador para a classificação de Fernandez foi de 76,4, e de 59,2% para a AO/OTA 2018. A concordância intraobservador foi de 77,3 e 56,6%, respectivamente. O índice de kappa inter- e intraobservador para a classificação de Fernandez foram de 0,57 e de 0,55, respectivamente, e a classificação AO/OTA 2018 obteve 0,34 e 0,31, respectivamente. Conclusão A classificação AO/OTA 2018 mostrou uma reprodutibilidade intra- e interobservadores baixa quando comparada à classificação de Fernandez. Porém, ambas as classificações apresentam índices intra- e interobservadores baixos. Embora a classificação de Fernandez não tenha obtido resultados excelentes, ela permanece com melhor concordância para o uso rotineiro.

Analysis of the Clinical and Radiological Results of Bridge Plate Versus External Fixation in Comminuted Distal Radius Fractures.

Objective To evaluate and compare the clinical and radiological outcomes of patients with comminuted distal radius fractures treated with an external fixator or a dorsal bridge plate. Methods In total, 45 patients were analyzed 1 year after surgery; 18 were treated with an external fixator, and 25 received a dorsal bridge plate. An analog pain scale and the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire were applied, in addition to radiographic, strength and range of motion assessments. Statistical analyzes were performed using the chi-squared test and the Mann-Whitney non-parametric test. Results Fractures were more common in women over 60 years old who suffered falls from their own height. Both methods demonstrated similar functional and radiological results. Infections were more prevalent in patients receiving external fixators, but their residual grip strength was better. Reflex sympathetic neuropathy was more common in subjects treated with a dorsal bridge plate. Conclusion Our analysis showed no consensus on the superiority of one method over the other. Each method had advantages and disadvantages, but both led to good, similar outcomes. The treatment must be chosen according to the profile of the trauma, the patient's clinical conditions, the surgeon's experience, and the availability of materials.

Resumo Objetivo Avaliar e comparar os resultados clínicos e radiológicos de pacientes com fraturas cominutivas distais do rádio tratados com fixador externo ou placa ponte dorsal. Métodos Foram analisados 45 pacientes, sendo 18 tratados com fixador externo, e 25, com placa ponte dorsal, após 1 ano de pós-operatório. Aplicou-se uma escala analógica de dor e o questionário Disabilities of the Arm, Shouder and Hand (DASH), além de análise radiográfica, da avaliação de força, e da amplitude de movimento. As análises estatísticas foram realizadas utilizando o teste qui-quadrado e o teste não paramétrico de Mann-Whitney. Resultados A fratura foi mais comum em mulheres acima de 60 anos por queda do mesmo nível. Ambos os métodos demonstraram resultados funcional e radiológico similares. A infecção foi mais prevalente com o uso do fixador externo, mas a força de preensão residual foi melhor. Neuropatia simpático-reflexa foi mais comum com o uso da placa ponte dorsal. Conclusão Não houve consenso da superioridade de um método em relação ao outro em nossa análise. Cada um dos métodos apresenta vantagens e desvantagens, mas ambos mostraram resultados bons e semelhantes. A escolha do tratamento deve ser atribuída ao perfil do trauma, às condições clínicas do paciente, à experiência do profissional, e à disponibilidade de materiais.

DISTAL HUMERAL FRACTURE: AN EPIDEMIOLOGICAL ANALYSIS OF ORTHOPEDIC PATIENTS FOR CHILDREN.

OBJECTIVE: To analyze the epidemiological profiles of children with orthopedic distal humerus fractures. METHODS: An analytical descriptive study was conducted with a retrospective approach using medical records of 665 orthopedic children who attended the Jesser Amarante Faria Children's Hospital, a reference hospital in the city of Joinville, Santa Catarina, between June 2012 and December 2016. RESULTS: The results showed a predominance of male patients (64.2%), with a mean age of 7 years, and the age group of 6-10 years being the most frequent with 319 patients (48%). The main mechanism of trauma was fall of height in 59.7% of patients, Gartland type 1 fracture in 57.1%, and absence of vascular injury in 99.7%. Conservative management was implemented in 64.7% (95%) of patients. Absence of neurological lesion (95.6%) and closed lesion (99.4%) were the main epidemiological characteristics of patients in the study. A low complication rate was observed, with reduction losses in 1.7% of patients, followed by infections in 1.1%. CONCLUSION: We can conclude that the cases studied presented epidemiological characteristics similar to those described in the literature. Level of evidence IV, Description of a case series, with analysis of results, without a comparative study.

OBJETIVO: Analisar o perfil epidemiológico de pacientes ortopédicos infantis com fratura de úmero distal. MÉTODO: Estudo analítico-descritivo, com abordagem retrospectiva dos prontuários médicos de 665 pacientes ortopédicos infantis, atendidos no Hospital Infantil Dr. Jeser Amarante Faria, referência no município de Joinville (SC), do período de junho de 2012 a dezembro de 2016. RESULTADOS: Os resultados mostraram um predomínio de pacientes do sexo masculino (64,2%), com idade média de 7 anos, sendo a faixa etária de 6 a 10 anos a mais frequente, com 319 (48%) pacientes. O principal mecanismo do trauma foi por queda da própria altura (59,7%), com Gartland 1 em 57,1% dos casos e ausência de lesão vascular (99,7%). A conduta conservadora foi observada em 64,7% dos pacientes, além de ausência de complicações imediatas (97,1%), complicações tardias (95,3%) e lesão neurológica (95,6%). Lesão fechada (99,4%) foi a principal característica epidemiológica dos pacientes estudados. Uma baixa frequência de complicações foi observada, sendo mais prevalentes as perdas de reduções (1,7%), seguidas de infecções, em 1,1% dos casos. CONCLUSÕES: Os casos estudados apresentaram características epidemiológicas semelhantes àquelas descritas na literatura. Nível de evidência IV, Descrição de série de casos, com análise de resultados, sem estudo comparativo.
