Zielke对Dwyer的前路脊柱内固定进行了改进，产生了腹侧旋椎体成形术（VDS）系统。VDS内固定的主要适应症是治疗特发性脊柱侧凸的进行性、单侧、主要腰椎或胸腰椎弯曲。手术技术，包括选择适当的曲率和水平的仪器，被描述。我们回顾了25例连续接受VDS内固定治疗腰椎或胸腰椎弯曲的患者。主曲线的平均修正率为76%。小曲率的平均矫正率为47%。一个重要的并发症是假关节和假棒断裂发生率为20%。讨论了这些问题的含义。齐尔克仪器是一种校正所选曲线的强大技术。该系统提供了更大的主曲线矫正，改善了额骨和矢状面对齐，并保留了远端运动节段。
Zielke modified Dwyer's anterior spinal instrumentation to produce the Ventral Derotational Spondylodesis (VDS) System. The primary indication for VDS instrumentation is the treatment of progressive, single, major lumbar or thoracolumbar curves in idiopathic scoliosis. The surgical technique, including selection of appropriate curvatures and levels of instrumentation, is described. A group of 25 consecutive patients undergoing VDS instrumentation for lumbar or thoracolumbar curvatures was reviewed. The average correction of the major curve was 76%. The minor curvature was corrected with an average of 47%. A significant complication was a 20% incidence of pseudarthrosis and rod breakage. The implications of these problems are discussed. Zielke instrumentation is a powerful technique for the correction of selected curves. The system provides greater correction of the major curve, improved frontal and sagittal alignment, and preservation of distal motion segments.
