BACKGROUNDCONTEXT: Consensus regarding the optimal upper vertebra to be instrumented during surgical treatment of Lenke 5C thoracolumbar and lumbar @entity1615 ( @entity1615 ) remains limited. PURPOSE: This study aimed to assess whether a short fusion strategy is appropriate for correction of a Lenke 5C @entity1615 curve by anterior correction and fusion surgery using dual-rod instrumentation. STUDY DESIGN: This study design used retrospective comparative analysis of a prospectively collected, consecutive, non-randomized series of @entity1 at a single institution. @entity1 SAMPLE: Thirty consecutive @entity1 with Lenke 5C @entity1615 treated with anterior correction and fusion surgery using dual-rod instrumentation were included. OUTCOME MEASURES: @entity1 demographics, radiographic measurements, and Scoliosis Research Society-22 questionnaire (SRS-22) scores were the outcome measures for this study. METHODS: Thirty @entity1 were treated surgically for @entity1615 with a Lenke 5C curve (mean age, 14.4 years [11-19 years)]) and followed up for a mean period of 17.2 years (12-23 years). Radiographical parameters and clinical outcomes were compared between @entity1 treatment with the end vertebra (EV) instrumented (n=14) and those treated by short fusion (S group) with instrumentation starting at the vertebra one level caudal to the EV (n=16 @entity1 ). There were no study-specific biases related to conflicts of interest. RESULTS: In the EV group, a mean preoperative Cobb angle of 56   was corrected to 5   after surgery and to 8   at the final follow-up. In the S group, a mean preoperative Cobb angle of 55   was corrected to 10   after surgery and 14   at the final follow-up. The mean correction rate at the final follow-up was significantly lower in the S group (74%) than in the EV group (86%; p=.020). The coronal and sagittal balance, @entity1513 , @entity1515 , and clinical outcomes evaluated using SRS-22 did not differ between the two groups. CONCLUSIONS: The short fusion strategy, which involves instrumentation of the vertebra one level caudal to the upper EV, can be considered as an alternative to the conventional strategy, which includes instrumentation of the upper EV, for treating Lenke 5C curves via anterior spinal fusion.
