Objective: To evaluate the gross motor function (GMFCS) with respect to the prevalence and type of scoliosis in patients with cerebral palsy (CP). Methods: This was an analytical, cross-sectional study. We evaluated medical records and imaging studies of 100 patients randomly assigned to a specialist rehabilitation center for the care of such patients. The patients were classified according the gross motor function (GMFCS) and those with deformities were classified as per the kind of scoliosis through the classification of Lonstein and Akbarnia). A correlation was made among the presence of deformity, the variables of the type of deformity and motor function by GMFCS. Results: Of the 100 patients evaluated, 69 had scoliosis. The mean age of patients with scoliosis was higher than that of patients without deformity (12.63 and 10.46 years). Thirty-nine (57%) patients had spastic tetraparesis and 32 (46%) spastic diparesis. The most frequent curve pattern was the thoracolumbar and the average angular value of the main curve was 27 degrees. There was a positive correlation between the presence of scoliosis and GMFCS level V. There was also a positive correlation between the Lonstein Group II and GMFCS V. Conclusion: There is a positive correlation between the presence of scoliosis and greater involvement of gross motor function (GMFCS V). In patients with deformities, there is also a positive correlation between the Group II of Lonstein and GMFCS V.Keywords: Spine; Cerebral palsy; Scoliosis; Epidemiology.

Também houve correlação positiva entre o Grupo II de Lonstein e GMFCS V. Conclusão: Existe uma correlação positiva entre a presença de escoliose e maior acometimento da função motora grossa (GMFCS V). Nos pacientes com deformidades, também existe uma correlação positiva entre o Grupo II de Lonstein e o GMFCS V.Descritores: Coluna vertebral; Paralisia cerebral; Escoliose; Epidemiologia.

Objectives: To evaluate the cervical alignment after the correction of idiopathic scoliosis using high screw density and direct vertebral derotation (DVD) and to correlate it with thoracic kyphosis, spinopelvic parameters, and quality of life. Methods: Retrospective cohort study. We assessed the medical records and radiographs of patients submitted to idiopathic scoliosis surgery using high density of pedicular screws (80%) and DVD with at least 6 months of follow-up. All the radiographic parameters were evaluated in the preoperative period and in the last postoperative visit. Results: A total of 43 patients were evaluated, of which 35 (81%) were female. The mean age was 15 years (11 to 30 years) with a mean follow-up of one year and four months. Regarding Lenke's classification, 14 were of group 1, five of group 2, 10 of group 3, eight of group 4, four of group 5 and two of group 6. Only four patients had sagittal modifier (+) and two sagittal modifier (-).There was no significant difference between pre and postoperative thoracic kyphosis. When we evaluated the groups with +, N and -thoracic modifiers, we observed hypokyphotic and normokyphotic patients (-and N) had an increase in kyphosis, whereas hyperkyphotic patients (+)had a decrease. There was no statistical difference in relation to the radiographic parameters of the cervical spine in the pre and postoperative periods. There was a significant improvement in most of the parameters of the quality of life questionnaires, but no correlation with the cervical radiographic parameters. Conclusion: Correction of idiopathic scoliosis using a high density of pedicular screws and a direct vertebral derotation technique failed to improve thoracic kyphosis or change the cervical sagittal alignment, despite promoting a significant improvement in the parameters of quality of life questionnaires.Keywords: Scoliosis; Treatment outcome; Quality of life; Orthopedic fixation devices. RESUMO Objetivos: Avaliar o alinhamento cervical após a correção da escoliose idiopática utilizando alta densidade de parafusos e derrotação vertebral direta (DVD) e correlacionar com a cifose torácica, parâmetros espinopélvicos e qualidade de vida.

INTRODUÇÃO: a cifose pós-traumática é uma complicação do tratamento conservador da fratura toracolombar tipo flexo-distrativa de Magerl (B21). A maioria das séries avalia todos os subtipos de Magerl e discute seus achados com base na perda média de cifose no acompanhamento. OBJETIVO: avaliar o desfecho radiográfico quanto à cifose nos portadores de fraturas do subtipo B21 de Magerl, de acordo com a variação das médias entre os indivíduos após acompanhamento mínimo de seis meses. MÉTODOS: estudo retrospectivo com 34 pacientes submetidos à realização de gesso antigravitacional ou colete TLSO. A mensuração da cifose foi realizada pelo método de Cobb no momento da admissão no hospital e no final do acompanhamento médio de 84,5 meses. RESULTADOS: não houve diferença estatística entre a cifose antes e após o tratamento (14,18º versus 14,15º; (p=0,967). CONCLUSÃO: a cifose radiográfica no final do acompanhamento é similar à cifose encontrada nas radiografias iniciais nesse grupo de pacientes.

Objective: To describe the surgical technique for vertebrectomy by posterior single approach in the thoracic and thoracolumbar spine with circumferential reconstruction and arthrodesis, and evaluate retrospectively the results and complications after 2 years of follow-up in patients undergoing this technique. Methods: Retrospective analysis of medical records and imaging studies of 12 patients with vertebrectomy indication for various pathologies, undergoing this surgical technique. Results: Eight (66.67%) patients were male and four patients (33.33%) were females aged 13-66 years (mean 40 years). There were nine patients with involvement of the thoracic spine and three of the lumbar, and one patient with two consecutive vertebrae affected. All patients had improved or remained with the neurological condition. Surgical complications were two cases of hemothorax, two cases of loosening of the screws, one of them requiring surgical revision, and a case of material failure and pseudarthrosis. Conclusion: Vertebrectomy by posterior approach in thoracolumbar spine with circumferential reconstruction and fusion can be performed safely for a variety of indications.

Objectives: To present the clinical and radiographic results of patients with thoracic disc herniation treated by the posterior approach, according to location and type of hernia (à la carte). Methods: We evaluated thirteen patients (14 hernias) treated by the posterior approach. Eight (61.5%) patients were male and the mean age was 53 years . Clinical evaluation was performed by the Frankel and JOA modified scales. All the patients underwent the posterior approach, which was performed by facetectomy, transpedicular approach, transpedicular + partial body resection, costotransversectomy or costotransversectomy + reconstruction with CAGE. Results: The mean follow-up was 2 years and 6 months (11-77 months). Of the 14 operated hernias, six (43%) were lateral, 2 (14%) paramedian, and 6 (43%) central. Seven were soft (50%) and seven were calcified. The transfacet approach was carried out in 5 cases (36%), transpedicular in 1 case (7%), transpedicular + partial body resection in 4 (29%), costotransversectomy in 3 (21%), and costotransversectomy + CAGE in one case (7%). The majority of patients with lateral hernia (5/6) were subjected to transfacet decompression and in cases of central and paramedian hernias, all patients underwent decompression, which is more extensive. Conclusions: The posterior approach is safe and effective, and the best approach must be chosen based on location and type of the herniation and the surgeon's experience.
