This series includes 59 consecutive patients, 51 of whom had a minimum follow up of 2 years. The diagnosis was mechanical instability in 39, deformity in 11, and infection or tumor in 9 patients. The overall clinical results of the total group were good or fair in 88% of the patients. Pseudarthrosis occurred twice. We had on postoperative infection, one persistent and two reversible neurological complications. We found 13 broken screws and one rod breakage which had no clinical relevance. None of these asymptomatic complications required revision. The internal fixator has a great potential of correction in scoliotic and kyphotic deformities of the spine. It has not been shown to have the same potential in spondylolisthesis. A combined anterior and posterior stabilisation is needed in severe spondylolisthesis. We have found the internal fixator to provide satisfactory stability to allow fusion and good clinical results with a low rate of relevant complications.
该系列包括59例连续患者，其中51例至少随访了2年。诊断为机械性不稳定的有39例，畸形11例，感染或肿瘤9例。全组患者总体临床结果88%为良好或尚可。发生了2例假关节。有1例术后感染、1例持续性和2例可逆性神经并发症。发现13枚螺钉断裂和1根棒材断裂，但无临床相关性。这些无症状并发症均无需翻修。该内固定器在脊柱侧弯和后凸畸形的矫正方面有很大潜力。在腰椎滑脱中尚未显示出同样的潜力。严重腰椎滑脱需要前后联合稳定。我们发现该内固定器能提供令人满意的稳定性，以实现融合，临床效果良好，相关并发症发生率低。
