Abstract

Purpose: To present a case where the novel Modern Luque Trolley (MLT) technique was used to manage a patient with early onset scoliosis (EOS) and to assess the outcomes including graduation to fusion.

Methods: Case report.

Results: A 5-year-old female with EOS associated with Prader-Willi syndrome underwent T5-L4 MLT surgery in April 2015. The operation, post-operative course, and 9-year follow-up period were uncomplicated. No autofusion occurred throughout the 7-year growth phase. In April 2022, the patient underwent elective uncomplicated "graduation" surgery to remove the MLT and posterior T5-L4 instrumented fusion was performed. Thirty-one months post-graduation, no complications occurred. During the 7-year growth phase, pre-index, immediate post-index, and 7-year post-index radiographs were analyzed. Scoliosis decreased from 52° to 10° post-index and then increased at 7 years to 31°. Maximal kyphosis increased from 24° to 27° post-index to 43^o at 7 years. T1-T12 coronal height increased from 16.0 cm post-index to 20.7 cm at 7 years. T1-S1 coronal height increased from 25.9 cm post-index to 33.9 cm at 7 years. T1-T12 sagittal spine length (SSL) was 15.6 cm post-index and then increased to 20.4 cm at 7 years. T1-S1 SSL increased from 27.2 cm post-index to 35.8 cm 7 years. T1-T12 3D true spine length (3D-TSL) increased from 16.2 cm post-index to 21.5 cm 7 years and T1-S1 3D-TSL increased from 27.3 cm post-index to 36.4 cm 7 years.

Conclusion: These findings demonstrate the potential of MLT to decrease spine deformity and permit spinal growth while reducing autofusion.

现代Luque小车技术在早发性脊柱侧凸手术治疗中的应用：1例患者随访至成熟并最终融合。

目的：介绍一种新型现代Luque小车（MLT）技术用于治疗早发性脊柱侧凸（EOS）患者，并评估包括毕业到融合的结果。方法：病例报告。结果：2015年4月，一名5岁EOS合并prder - willi综合征的女性接受了T5-L4 MLT手术。手术、术后病程及9年随访均无并发症。在整个7年的生长阶段没有发生自融合。2022年4月，患者接受了选择性的简单“毕业”手术，切除了MLT，并进行了后路T5-L4固定融合。毕业后31个月，无并发症发生。在7年的生长阶段，分析指数前、指数后和指数后7年的x线片。脊柱侧凸从52°下降到10°，7年后增加到31°。最大后凸度从24°增加到27°，7年后增加到430°。T1-T12冠状高度从指数后的16.0 cm增加到7年后的20.7 cm。T1-S1冠状高度从指数后的25.9 cm增加到7年后的33.9 cm。T1-T12矢状位脊柱长度（SSL）指数后为15.6 cm， 7年时增加到20.4 cm。T1-S1层厚由指数后的27.2 cm增加到7年后的35.8 cm。T1-T12三维真脊柱长度（3D- tsl）从指数后的16.2 cm增加到21.5 cm， T1-S1 3D- tsl从指数后的27.3 cm增加到36.4 cm。结论：这些发现证明了MLT在减少自体融合的同时减少脊柱畸形和脊柱生长的潜力。
