RESUMO
STUDY DESIGN: Pilot test, observational study. OBJECTIVE: To evaluate objectively the knowledge transfer provided by theoretical and practical activities during AOSpine courses for spine surgeons. METHODS: During two AOSpine principles courses, 62 participants underwent precourse assessment, which consisted of questions about their professional experience, preferences regarding adolescent idiopathic scoliosis (AIS) classification, and classifying the curves by means of the Lenke classification of two AIS clinical cases. Two learning strategies were used during the course. A postcourse questionnaire was applied to reclassify the same deformity cases. Differences in the correct answers of clinical cases between pre- and postcourse were analyzed, revealing the number of participants whose accuracy in classification improved after the course. RESULTS: Analysis showed a decrease in the number of participants with wrong answers in both cases after the course. In the first case, statistically significant differences were observed in both curve pattern (83.3%, p = 0.005) and lumbar spine modifier (46.6%, p = 0.049). No statistically significant improvement was seen in the sagittal thoracic modifier (33.3%, p = 0.309). In the second case, statistical improvement was obtained in curve pattern (27.4%, p = 0.018). No statistically significant improvement was seen regarding lumbar spine modifier (9.8%, p = 0.121) and sagittal thoracic modifier (12.9%, p = 0.081). CONCLUSION: This pilot test showed objectively that learning strategies used during AOSpine courses improved the participants' knowledge. Teaching strategies must be continually improved to ensure an optimal level of knowledge transfer.
RESUMO
ABSTRACT Objective: To evaluate clinical and functional results of patients with lumbar degenerative spondylolisthesis treated with operatively or nonoperatively. Methods: Patients with degenerative spondylolisthesis treated either nonoperatively or operatively from 2004 to 2014 were selected from databases and a cross-sectional evaluation was performed. Outcome measures included back and leg visual analogue scales (VAS), Fischgrund criteria, Short Form-36 (SF-36) function score, and the modified Oswestry Disability Index (ODI). Results: 43 patients were evaluated: 20 with nonoperative treatment and 23 with operative treatment. Baseline characteristics were similar without significant differences between groups. Mean follow-up time was 43 months (range 10 - 72) for the nonoperative group and 36 months (range 6-80) for the operative group. Significant statistical difference in favor of operative group were found in back VAS (mean 4 versus 8, p = 0.000), leg VAS (mean 3 versus 6, p = 0.0015), SF-36 function score (mean 77 versus 35, p = 0.000), and ODI (mean 17 versus 46, p = 0.000). On the basis of the Fischgrund criteria, only 10 % of patients reported excellent or good health post nonoperative treatment versus 83% for those treated operatively (p = 0.000). Conclusion: In this cross-sectional study, we observed that symptomatic patients with degenerative spondylolisthesis who underwent operative treatment have superior clinical and functional scores compared to those that underwent nonoperative treatment.
RESUMO Objetivo: Avaliar os resultados clínicos e funcionais dos pacientes com espondilolistese degenerativa lombar tratados de maneira conservadora ou cirúrgica. Métodos: Foram selecionados pacientes com espondilolistese degenerativa tratados conservadoramente ou submetidos à cirurgia, durante 2004-2014, à partir da coleta de dados que possibilitou a realização da avaliação transversal. As medidas de avaliação da dor lombar e das pernas foram escalas analógicas visuais (VAS), critérios Fischgrund, Short Form-36 (SF-36) pontuação funcional, e o Índice de Incapacidade Oswestry modificado (ODI). Resultados: 43 pacientes foram avaliados: 20 do tratamento conservador e 23 do tratamento cirúrgico. As características de base foram similares, sem diferenças significativas entre os grupos. O tempo médio de acompanhamento foi de 43 meses (intervalo 10-72) para o grupo não-cirúrgico e 36 meses (intervalo 6-80) para o grupo cirúrgico. Diferenças estatísticas significativas em favor do grupo cirúrgico foram encontrados no VAS lombar (média de 4 versus 8, p = 0,000), VAS pernas (média 3 contra 6, p = 0,0015), SF-36 pontuação funcional (média 77 versus 35, p = 0,000), e ODI (média 17 versus 46, p = 0,000). Com base nos critérios Fischgrund, apenas 10% dos pacientes relataram excelente ou boa saúde de após o tratamento conservador contra 83% para aqueles tratados no cirúrgico (p = 0,000). Conclusão: Neste estudo transversal, observou-se que os pacientes sintomáticos com espondilolistese degenerativa que se submeteram ao tratamento cirúrgico têm escores clínicos e funcionais superiores em comparação àqueles que foram submetidos a tratamento conservador.
RESUMEN Objetivo: Evaluar los resultados clínicos y funcionales de los pacientes con espondilolistesis degenerativa lumbar tratados quirúrgicamente o sin cirugía. Métodos: Se realizó una evaluación transversal de los pacientes con espondilolistesis degenerativa, registrados en la base de datos, tratados conservador o quirúrgicamente desde 2004 hasta 2014. Las medidas de desenlace incluyeron: Escala Visual Análoga (EVA) de dolor lumbar y las piernas, criterios de Fischgrund, Short Form-36 (SF-36) e Índice de Discapacidad Oswestry modificado (IDO). Resultados: Se evaluaron 43 pacientes: 20 con tratamiento no quirúrgico y 23 con tratamiento quirúrgico. Las características de base fueron similares, sin diferencias significativas entre los grupos. El tiempo medio de seguimiento fue de 43 meses (rango 10-72) para el grupo no quirúrgico y 36 meses (rango 6-80) para el grupo quirúrgico. Diferencias estadísticamente significativas a favor del grupo quirúrgico fueron encontrados en EVA lumbar (media 4 contra 8, p=0,000), EVA pierna (media 3 contra 6, p=0,0015), SF-36 función (media 77 contra 35, p=0,000), e IDO (media 17 contra 46, p=0,000). Con respecto a los criterios de Fischgrund, sólo el 10% de los pacientes del grupo que recibió tratamiento no quirúrgico informo excelente o buen estado de salud en comparación con 83% de los que recibieron manejo quirúrgico (p = 0,000) Conclusión: En este estudio de corte transversal, se observó que los pacientes sintomáticos con espondilolistesis degenerativa que se sometieron a tratamiento quirúrgico tienen puntuaciones clínicas y funcionales superiores en comparación con los que se sometieron a tratamiento no quirúrgico.
