摘要

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 43o 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.
