Sixty-six patients who underwent anterior spinal fusion with Zielke instrumentation for thoracolumbar and lumbar curvatures were reviewed. Results compared favorably with reported series in which the Dwyer instrumentation system was used. The best corrections were obtained in the idiopathic single-curve group (45% correction of upper curve, 87% correction of lower curve, and 95% correction of instrumented curve) as compared with the double-curve group (33% correction of upper curve, 53% correction of lower curve, and 62% correction of instrumental curve). Vertebral body lateral translation (subluxation) was completely corrected in 87% of the patients. Instrumentation kyphosis can be prevented by placement of anterior wedge grafts in the intervertebral spaces. Complications were frequent but usually insignificant. The use of the Zielke instrumentation system offers the advantage of improved ability to derotate the spine while obtaining significant curve correction in a short fusion area.
对66例行前路脊柱融合术并使用Zielke器械治疗胸腰段和腰椎侧弯的患者进行了回顾性研究。结果与使用Dwyer器械系统的报道系列相比更具优势。与双弯组相比，特发性单弯组获得了最佳的矫正效果（上弯矫正45%，下弯矫正87%，器械矫正弯度95%）（双弯组上弯矫正33%，下弯矫正53%，器械矫正弯度62%）。87%的患者椎体侧方移位（半脱位）得到完全矫正。通过在椎间隙植入前路楔形植骨可预防器械性后凸。并发症很常见，但通常不严重。使用Zielke器械系统的优点是在短融合区域内获得显著的弯度矫正的同时，具有更好的脊柱去旋转能力。
