Resumo (PT): A fusão intervertebral é uma técnica cirúrgica cada vez mais utilizada no tratamento da instabilidade sintomática da coluna vertebral, nomeadamente a estenose espinhal, a espondilolistese e a escoliose degenerativa. Este trabalho apresenta uma fusão intervertebral anterior minimamente invasiva (ALIF) no nível L5-S1, aplicando o implante SynFix para investigar a estabilidade da coluna durante a recuperação, considerando a fase inicial e a fase final do pós-operatório. Na fase inicial, principalmente no caso de carga de extensão, os ângulos de rotação são muito maiores do que os obtidos na fase final do pós-operatório, evidenciando maior instabilidade da coluna vertebral.
Abstract (EN): Lumbar spinal fusion has evolved as a treatment option for symptomatic spinal instability, spinal stenosis, spondylolisthesis, and degenerative scoliosis. This work presents a minimally invasive anterior lumbar interbody fusion (ALIF) at the L5-S1 level, applying the SynFix implant in order to investigate spine stability during the recovery considering the early and long-term postoperative phases. In the early postoperative phase, namely for extension load case, rotation angles are much greater than the ones obtained in the longterm postoperative phase, showing a greater spine instability.
