RESUMOObjetivo: Verificar a influência da extensão da fusão póstero-lateral lombossacra e seu impacto nos resultados clínicos e funcionais. Métodos: Foram avaliados 22 pacientes portadores de estenose central, foraminal ou hérnia de disco lombar, associadas a instabilidade segmentar, submetidos ao tratamento cirúrgico para a descompressão neural e artrodese póstero-lateral. Os pacientes foram divididos em dois grupos, de acordo com quantidade de níveis artrodesados: Grupo 1: fusão em um nível e Grupo 2: fusão em dois ou mais níveis. Os pacientes preencheram questionários referentes ao acompanhamento pós-operatório (uso de medicamentos analgésicos e satisfação com o tratamento) e escala analógica visual de dor lombar e ciática. Além disto, foram aplicados os questionários Oswestry e SF-36 para avaliação da qualidade de vida. Resultados: Os resultados do SF-36 mostraram bons níveis de qualidade de vida em ambos os grupos, com exceção do domínio "Aspectos Físicos". Não houve correlação significativa entre a extensão da artrodese e os desfechos clínicos. Conclusões: Os pacientes submetidos à artrodese póstero-lateral apresentaram qualidade de vida satisfatória, exceto pela diminuição da aptidão física. Entretanto, o maior número de níveis artrodesados não teve impacto negativo sobre os aspectos clínicos e funcionais.
Objective: To evaluate the reproducibility and the interobserver coefficient of concordance between the AO/Magerl and AOSpine classifications for thoracolumbar spine fractures. Methods: Retrospective study of radiographic data analysis. Data were collected from 31 radiographic studies of patients with thoracolumbar spine fracture and distributed to a team involving spinal surgeons and residents. The fractures were classified according to the AO/Magerl and AOSpine classifications. Statistical analysis was performed using the Cohen Kappa test to assess the coefficient of concordance. Results: The Kappa value for interobserver concordance of AO/Magerl classification was κ = 0.70 and standard deviation was 0.16. For the AOSpine classification, we observed κ = 0.76, both with significance level α = 0.05 and P<0.001. Conclusions: We conclude that the interobserver concordance of the new AOSpine classification is similar to the AO/Magerl classification. This conclusion reinforces the reproducibility of the new AOSpine classification. Level of evidence: IV,Type of Study: Case series.
Objectives: To quantify the changes in cervical sagittal alignment of patients with adolescent idiopathic scoliosis (AIS) who underwent surgical treatment. Methods: Retrospective study of radiographic data analysis. Data were collected from 25 radiographs of patients with AIS, and 18 cases were included. The mean age was 15.2 years (13-17 years); all subjects were female, operated from March 2010 to October 2015. Pre and postoperatively, cervical lordosis (C2-C7), thoracic kyphosis (T5-T12) and lumbar lordosis (L1-S1) were measured. Scoliotic curves were analyzed and measured in anterior posterior views by the Cobb method and classified according to the Lenke classification. Results: Eighteen adolescent patients were evaluated with a mean follow-up of 31.3 months. There was a negative correlation (-0.613) between post-surgical and pre-surgical cervical lordosis variation, that is, the largest the angulations obtained, on average, the greatest the reductions. Thus, the correlation becomes positive when compared to postoperative period (0.579). Conclusion: We concluded that the correction of adolescent idiopathic scoliosis did not bring about statistically significant changes in the cervical spine, with respect to angle values. Lordotic cervical curves with greater angular value showed a greater variation in the postoperative period, resulting in a better biomechanical balance.Keywords: Scoliosis; Kyphosis; Spine. RESUMO
