ABSTRACT Objective This paper proposes a retrospective analysis of the spinal cord trauma at a regional hospital that is a Unified Health System (SUS) reference in Orthopedics and Traumatology, considering epidemiological data and comparing treatments and hospitalization costs. Methods This study is a retrospective, analytical-descriptive, exploratory documental analysis, using data from the medical records of patients treated for spinal cord trauma during 2016 at the São José Municipal Hospital (Joinville, SC). Results Twenty-three patients were included in the study, 20 of whom (87%) were male. As to etiology, traffic accidents accounted for 47.8% of the cases and gunshot wounds were in second place with 26.1% of the injuries. The correlation between the cost of hospitalization and the days of hospitalization was statistically significant (p = 0.013), as was the correlation between the cost of hospitalization and the number of procedures (p = 0.000). Conclusions Surgical treatment demands greater amounts of financial and human resources. The purpose of this study is to provide local epidemiological data to encourage discussion about other studies, as well as planning for resource allocation and public policy.

ABSTRACT Objective: To evaluate the reliability, response capacity and validity of four scales for low back pain and correlate these scales with each other and the Self-Administered Comorbidity Questionnaire (SACQ). Methods: We evaluated the psychometric properties of four previously selected scales for low back pain: the Roland-Morris Disability Questionnaire (RMDQ), the Quebec Back Pain Questionnaire (QBPDS), the Waddell Disability Index (WDI) and the Back Pain Functional Scale (BPFS) and Self-Administered Comorbidity Questionnaire (SACQ) comorbidity scale. Exploratory and confirmatory factor analyses were conducted. Reliability and internal consistency were measured by Cronbach's alpha. Validity was measured through correlation of the scales with the Self-Administered Comorbidity Questionnaire comorbidity scale and an analysis of the structural equations between them. Results: The scales showed adequate indicators based on the factor structure and showed Kaiser-Meyer-Olkin values above 0.90. After the exploratory factor analysis, all scales showed fit indicators suited to a factor model, following the same pattern as the original validations. Similarly, they showed good internal consistency (Cronbach's alpha greater than .78). The only scale that showed factor loadings suggesting the exclusion of any item was the Roland-Morris. In terms of validity, the scales showed positive correlation coefficients similar to the Self-Administered Comorbidity Questionnaire and between them. Conclusion: Regarding the scales evaluated, they showed similar indications of reliability and internal consistency, such that we did not find sufficient evidence to indicate one scale over another.

Apesar da importância de praticar o atendimento de saúde baseado em evidências, os cirurgiões ortopedistas têm direcionado poucos esforços para gerar essas evidências. Mesmo quando presente, a evidência publicada é falha quanto ao rigor metodológico e sabe-se que é imprecisa. Um dos principais motivos para a falta de geração de evidências de qualidade é o baixo envolvimento dos cirurgiões ortopedistas na pesquisa e a falta de ambientes de treinamento estruturados em pesquisa, onde eles possam aprender conceitos, assim como aprimorar suas habilidades em pesquisa. Existe a necessidade de uma abordagem objetiva que possa equipar os cirurgiões ortopedistas com métodos eficientes para transitarem da pesquisa para a escrita. Descrevemos um programa pragmático de treinamento em pesquisa, planejado e desenvolvido pelo grupo de Pesquisa sobre Pesquisa, que visa montar uma rede global de pesquisadores ortopedistas treinados em métodos de pesquisa funcionais e padronizados. Também fornecemos um rápido panorama sobre os princípios do curso e suas ferramentas, assim como plataformas usadas nesse programa.Despite the importance of delivering evidence-based health care, orthopedic surgeons have directed fewer efforts towards the generation of such evidence. Even when present, published evidence lacks methodological rigor and is known to be inaccurate. One of the main reasons for the lack of generation of quality evidence, and the low involvement in research among orthopedic surgeons, is the lack of structured research coaching environments where they can learn concepts and hone their research skills. There is a palpable need for a pragmatic and outcome-oriented approach that can equip orthopedic surgeons with effective ways of communicating their research in writing. We describe a pragmatic research coaching program, designed and developed by the Research on Research group, which aims to build a global network of orthopedic researchers trained in streamlined and standardized research methods. We also provide a brief overview of the course principles and tools, and the platforms used in this program.

Abstract Objective Translated and validated outcome instruments are of great importance, since they can be used for researchers studying different populations with the same problem. The objective of the present study was to translate, culturally adapt and validate the Hip Disability and Osteoarthritis Outcome Score (HOOS) into Brazilian Portuguese. Methods The HOOS was translated from English into Brazilian Portuguese, translated back into English, and submitted to an experts committee. It was administered to 100 patients with hip osteoarthritis. The psychometric evaluation included factor analysis; internal reliability measures, test-retest reliability at 7 days, and construct validity comparison with the Brazilian version of the Graded Chronic Pain Scale (GCPS). Results Factor analyses demonstrated a five-factor solution. The test-retest reliability showed a high degree of internal consistency for the five subscales (pain and physical difficulties, 0.97 at baseline and 0.93 at 7 days; pain and difficulty sitting, lying down and getting up, 0.93 at baseline and 0.89 at 7 days; difficulty flexing the knee, 0.92 at baseline and 0.83 at 7 days; difficulty walking, 0.88 at baseline and 0.87 at 7 days; quality of life, 0.80 at baseline and 0.35 at 7 days). The construct validity was established during the comparison of the Brazilian version of the GCPS. Conclusions A Brazilian version of the HOOS was developed with adequate reliability and validity. It will facilitate evaluation of the hip within a large patient population and across cultures.

Abstract 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.
