O tratamento cirúrgico da cifose de Scheuermann permanece um tópico em debate. Tratamento tradicional tem incluído liberação anterior associada à fusão dos segmentos discais apicais, seguida por instrumentação posterior. OBJETIVO: Avaliar se o uso do sistema de parafusos pedicular vertebral promove melhor estabilização e correção da deformidade, sem procedimento compressivo, diminuindo os risco de complicações. MÉTODOS: Foram avaliados 19 pacientes com cifose de Scheuermann, que foram submetidos à liberação e fusão anterior por toracotomia aberta, seguida por instrumentação posterior com sistema de parafuso pedicular vertebral posicionados pela técnica de mão livre. Pré-operatoriamente, os pacientes foram analisados pela escala analógica visual (EVA) de dor e radiografias. No pós-operatório, foi analisado o grau de correção da curva, complicações, EVA para dor e nível de satisfação com a cirurgia. A média de seguimento foi de 37,5 meses (12,6-61,7 meses). RESULTADOS: Cifose pré-operatória variou de 66° a 94°, com média de 77,6°, e média da EVA de 6,6 pontos. No pós-operatório a cifose média foi de 35,8° (variação de 23° a 50°), sendo obtida média de correção de 53,8%. A EVA foi de 0,6 ponto, com todos os pacientes, exceto um, satisfeitos com o resultado da cirurgia. Dentre as complicações: soltura de dois parafusos em um paciente, com necessidade de reintrodução e extensão da instrumentação, um paciente com infecção superficial resolvida clinicamente, uma quebra assintomática de parafuso e um paciente com infecção tardia resolvida com a retirada do implante. CONCLUSÃO: O tratamento cirúrgico da cifose de Scheuermann, usando liberação e fusão anterior por toracotomia aberta seguida por instrumentação posterior com sistema de parafuso pedicular vertebral por meio da técnica de mão livre, mostrou-se, nessa série de pacientes, segura e eficiente.Surgical treatment of Scheuermann's kyphosis is still subject to debate. Traditional treatment has included an anterior release associated to fusion of apical disk segments, followed by posterior instrumentation. OBJECTIVE: To evaluate if the vertebral pedicle screw system yields a better stabilization and correction of the deformity, without a compressive procedure, thus decreasing the risk of complications. METHODS: 19 patients with Scheuermann's kyphosis were evaluated after being submitted to anterior release and fusion by open thoracotomy followed by posterior instrumentation with a vertebral pedicle screw system with the screws positioned with the free-hand technique. Before surgery, the patients were analyzed according to the visual analogical pain scale (EVA) and using X-rays. After surgery, analysis was made of the extension of the curve correction, complications, EVA for pain, and level of satisfaction with the surgery. Mean follow-up was 37.5 months (12.6 61.7 months). RESULTS: Pre-op kyphosis varied from 66° to 94°, with a mean of 77.6° and the mean EVA was 6.6. After surgery, the mean kyphosis was 35.8° (ranging from 23° to 50°), a mean correction of 53.8% being obtained. EVA was 0.6, and all patients but one, were pleased with the result of the surgery. Complications: two screws were detached in one patient and had to be reintroduced and instrumentation had to be expanded, one patient had superficial infection that was clinically solved, a screw broke asymptomatically, and one patient had late infection that was cured with the removal of the implant. CONCLUSION: Surgical treatment of Scheuermann's kyphosis using anterior release and fusion by open thoracotomy followed by posterior instrumentation with a vertebral pedicle screw system using the free hand technique showed, in this series, to be safe and efficient.
