Oper Orthop Traumatol. 2023 Oct 10. doi: 10.1007/s00064-023-00830-w. Online ahead of print.ABSTRACTOBJECTIVE: Establishment of a physiological profile of the spine via reduction of the kyphotic slipped vertebra in the transverse and sagittal planes. Achieving solid fusion. Improvement of preoperative pain symptoms and prevention or elimination of neurological deficits.INDICATIONS: High-grade spondylolisthesis (Meyerding grade 3 and 4) as well as spondyloptosis after conservative treatment and corresponding symptoms. Serious neurological deficits, hip-lumbar extensor stiffness, are emergency indications.CONTRAINDICATIONS (CI): Individual risk assessment must be made. Absolute CI are infections with the exception of serious neurological deficits. Multiple abdominal operations or interventions on the large vessels can be a relative contraindication for ventral intervention.SURGICAL TECHNIQUE: For spondylolistheses of grade 3 according to Meyerding, we recommend a one-stage dorso-ventro-dorsal procedure with radicular decompression, correction and fusion in the index segment. From grade 4 according to Meyerding, reduction of the fifth lumbar vertebral body in the index segment L5/S1 is preceded by resection of the sacral dome. In cases of spondyloptosis, a two-stage procedure is often indicated. In this case, a screw-rod system spanning the index segment is implanted in the first step, which is used to distract the index segment for several days. Ventrodorsal reduction is perform...
