This study is a retrospective review of nine patients who underwent Luque instrumentation without fusion from 1982-1984. Average age at surgery was 9 years. Average preoperative curve was 51 degrees (30 degrees-70 degrees). All nine patients have had at least one revision. All of the revisions were technically difficult secondary to extensive fibrosis and weakened laminar bone. Spontaneous fusion was documented in all nine patients, limiting further correction. Final follow-up curves averaged 51 degrees (25 degrees-90 degrees). Average gain in spinal height was 5.8 cm (2.3 in) but only a small portion was derived from the instrumented levels. Segmental spinal instrumentation without fusion in immature patients was not effective in control of spinal deformity, nor did it allow anticipated growth under the instrumented regions.
本研究是对1982年至1984年间接受Luque器械固定但未融合的9例患者进行的回顾性分析。手术时的平均年龄为9岁。术前平均侧弯角度为51度（30度至70度）。所有9例患者均至少接受过一次翻修手术。所有翻修手术均因广泛纤维化和椎板骨薄弱而在技术上具有挑战性。所有9例患者均记录到自发融合，限制了进一步的矫正。末次随访时的侧弯角度平均为51度（25度至90度）。脊柱高度平均增加5.8厘米（2.3英寸），但只有一小部分来自器械固定节段。在未成熟患者中进行非融合节段性脊柱器械固定对控制脊柱畸形无效，也无法使器械固定区域实现预期生长。
