Objective: This study aims to demonstrate the results of surgical treatment of lower cervical spine in 34 patients with traumatic fracture--dislocation treated by surgical technique for arthrodesis with fixation without the aid of cranial traction. Methods: Patients were evaluated by clinical and radiological assessment. Patients were followed-up for a period of 1-4 years. Results: Clinical and radiological fusion was observed in all 34 patients, among them four developed surgical site infection. Conclusion: The performance of reduction of fracture dislocation of the lower cervical spine without the use of cranial traction together with surgical anterior approach showed good results with radiological and clinical improvements, as well as low rate of neurological complications.
Objective: To evaluate the interobserver agreement of the new AOSpine classification for subaxial cervical fractures. Methods: A descriptive study, which11 traumatic lesions of the subaxial cervical spine (through radiographic and tomographic images), were evaluated by 16 observers being: 6 senior surgeons, 4 fellows in spinal surgery and 6 physicians residents in Orthopedics and Traumatology by the new AOSpine classification, with subsequent statistical analysis of the results. An agreement analysis was performed using the Kappa coefficient, both individually and in combination, with an interpretation of the index performed using the standardized model for Landis and Koch. To determine the level of significance of the analyzes, values less than 0.05 were considered statistically significant. Results: In general, the level of agreement among the examiners was considered reasonable. The lesions “A0 (F3)”, “A4 (F3)”, “B1”, “B3”, “B3 (F3)”, “C”, “C (F3)” and “F3”showed a low level of agreement between the examiners. The level of reasonable agreement was obtained between fractures “A0”, “A1”, “A4”, “B2” and “C (F4)”. The only fracture that presented a moderate level of agreement was the “C (F4 BL)” lesion. This result indicates that the referred injury was the fracture of the subaxial column that presented the best level of agreement among the 16 examiners in the present study. Conclusions: The results of the study indicate an intermediate agreement of the new AOSpine classification for subaxial cervical lesion and point to the need to carry out studies that seek to evaluate this new classification in order to better evaluate its strengths and weaknesses, contributing for its improvement.

OBJETIVO: o manejo das fraturas toracolombares estáveis é controverso, especialmente em pacientes sem déficit funcional. Este estudo questiona o motivo de ser realizada uma avaliação das imagens apenas na posição supina, uma vez que, paradoxalmente, o tratamento conservador inclui o ortostatismo precoce. O propósito deste estudo é determinar se a realização de radiografias em posição ortostática influencia na definição do tratamento dos pacientes com fraturas torácicas e lombares classificadas como tipo "A" da AO-ASIF. MÉTODOS: de janeiro de 2007 a novembro de 2008, foram avaliados pacientes portadores de fraturas torácicas e lombares por meio de radiografias em decúbito e tomografia computadorizada, visando identificar sinais de instabilidade. As fraturas classificadas radiograficamente como tipo "A" da AO-ASIF, inicialmente por tratamento conservador, foram submetidas à realização de radiografias em ortostatismo sem o colete ortótico na fase aguda e seus parâmetros radiológicos foram reavaliados. RESULTADOS: foram incluídos neste estudo 59 pacientes com fraturas toracolombares estáveis (T11 a L4), e todos toleraram o exame. A cifose vertebral aumentou 46,8%. O colapso anterior aumentou 15,52%. Três destes pacientes (5,1%) receberam a indicação cirúrgica após radiografias em ortostatismo por apresentarem critérios de instabilidade. CONCLUSÕES: a realização das radiografias em ortostatismo mostrou-se eficiente na identificação de pacientes com instabilidade ainda não manifesta e capaz de predizer a evolução satisfatória durante o tratamento conservador, além de ser um exame diagnóstico seguro, de fácil aplicabilidade e com baixo custo. Neste estudo, um total de 5,1% dos pacientes tiveram seu tratamento conservador alterado para o cirúrgico.
OBJETIVO: justificar a reconstrução da pars interarticularis pela técnica modificada de Buck como método efetivo no tratamento de lombalgia por espondilólise ou espondilolistese tipo 1, refratárias ao tratamento conservador. MÉTODOS: avaliação retrospectiva de oito pacientes com idade entre 11 e 34 anos, operados e acompanhados no período de outubro de 2004 a maio de 2008 com a técnica de Buck utilizando-se parafusos canulados de titânio. Nenhum paciente foi imobilizado no pós-operatório. Os pacientes foram selecionados após serem submetidos a estudos por imagem utilizando radiografias e ressonância magnética. Também foram avaliados no pós-operatório, segundo os critérios de Henderson e quanto à satisfação com o tratamento, assim como o índice de consolidação. RESULTADOS: sete pacientes foram classificados como excelentes, retornando ao nível de prática esportiva e laboral prévia. Dentre eles, um evoluiu com parestesia transitória, com recuperação completa. A oitava paciente apresentou uma pseudartrose bilateral, mas com bom resultado do ponto de vista clínico. Todos os pacientes ficaram satisfeitos com o resultado. CONCLUSÃO: a reconstrução ístmica com parafusos de titânio atingiu excelentes resultados ao aliar biomecânica estável, dissecção mínima da musculatura, com preservação da anatomia e mobilidade do segmento.
Objective To evaluate the immediate correction capacity of the Wood-Chêneau-Rigo brace (WCR), produced using digital technological resources and robotic engineering, in primary and secondary curves of adolescent idiopathic scoliosis (AIS). Methods A retrospective study was conducted of 138 patients with a diagnosis of AIS and who received a WCR brace from a laboratory that makes orthoses and orthopedic prostheses between 2019 and 2021. These individuals were submitted to an independent analysis of the radiographic parameters by a single researcher, the main outcome of which was the standardized measurement of the main and secondary curves using the Cobb method. The radiographs analyzed were performed in orthostasis before and immediately after the adaptation of the brace on the patient. The correction capacity was calculated as the ratio of the difference between the pre- and post-brace curves to the pre-brace curve. Results The mean correction with the WCR was 48.4% for the main curve and 41.0% for the secondary curve. The level of correction of the main curve was significantly higher in patients with a main curve with the apex of convexity in the thoracolumbar region (p = 0.004), especially in the left thoracolumbar region (p = 0.010); curves of magnitude between 10º and 24.9º (p <0.001); and curves classified as simple (p <0.001). Conclusion The use of the WCR, which is produced using modern technological resources, was effective in the immediate correction of AIS. Long-term studies on this new modality of conservative scoliosis treatment are necessary. Level of evidence III; Retrospective study.
Objective: Retrospective study of the functional outcome of patients with lumbar disc herniation who underwent full-endoscopic discectomy. Methods: Fifteen consecutive patients, 10 men and 5 women, mean age of 34.2 years, were evaluated at 15, 30, 90 and 180 days after surgery through the Oswestry Disability Index (ODI) questionnaire and the Visual Analogue Scale (VAS) of axial and lower limbs pain. Results: There was a significant improvement in ODI evaluation of patients when comparing the preoperative results with the third and sixth postoperative month (p<0.05), as well as the VAS for preoperative axial pain with respect to 15, 30 and 90 days (p<0.05) after surgery, and VAS for preoperative pain in the lower limbs with respect to 15, 90 and 180 days postoperatively (p<0.05). Conclusion: The full-endoscopic discectomy is an effective procedure which should be considered as an alternative to conventional discectomy.Keywords: Endoscopy; Hernia; Low back pain; Sciatica; Intervertebral disc. RESUMO
Introduction: This study aims to evaluate the safety of using the cortical path screw with transfixation of the second cortical bone in relation to the vascular structures. Methods: This retrospective observational study (level of evidence: III, study of non-consecutive patients) analyzed data from the medical records of patients who underwent computed angiotomography scans of the abdomen at Hospital Mater Dei, measuring, in millimeters, the distance between the point of the lumbar vertebra considered the anatomical reference for the transfixation of the second cortical bone and the vascular structures adjacent to the spine (abdominal aorta, inferior vena cava, iliac vessels, segmental lumbar arteries). Results: Forty-eight patients were evaluated, with a mean age of 60 years (±8 years, 41-75), of whom 52% were male and 48% female. The measurements obtained between the pre-vertebral vessels and the possible screw exit points did not demonstrate contact in any of the vertebrae studied. Conclusions: The measurements obtained suggest the safety of using the cortical path screw transfixing the second cortical bone. Knowing the position of the vessels is essential to reduce intra- and postoperative complications related to spinal instrumentation. Level of evidence III; Study of non-consecutive patients.
