Correção das deformidades sagitais fixas pela técnica de osteotomia de subtração pedicular (PSO)

Abstract: OBJETIVO: O objetivo deste estudo foi avaliar os resultados radiográficos, bem como, as complicações precoces e tardias, da técnica de osteotomia de subtração pedicular (PSO) em pacientes com deformidades sagitais fixas. MÉTODOS: Foram avaliados os prontuários e as radiografias panorâmicas em perfil, realizadas no pré- e pós-operatório, de nove pacientes. Todos foram submetidos à osteotomia ao nível lombar (três ao nível L3 e dois ao nível L2). No grupo estudado, quatro pacientes possuíam o diagnóstico de espo… Show more

“…In the last decade, subtraction osteotomies have become popular in the management of spinal deformities2, 3 and have begun to be used in a wide range of situations. The focuses of this study are pedicular subtraction osteotomy (PSO), bone-disk-bone osteotomy (BDB), and vertebral column resection (VCR), all of which are posterior, middle, and anterior resection techniques through a single posterior access that can be used in very rigid deformities, with three-column arthrodesis or ankylosis, providing significant angular corrections in a single level without elongation of the anterior column of the spine (Fig.…”
