Comparison Between Stable Sagittal Vertebra and First Lordotic Vertebra Instrumentation for Prevention of Distal Junctional Kyphosis in Scheuermann Disease: Systematic Review and Meta-analysis

This study was a systematic review and meta-analysis. Objectives: To compare stable sagittal vertebra (SSV) and first lordotic vertebra (FLV) instrumentation for prevention of distal junctional kyphosis (DJK) in Scheuermann disease. Summary of Background Data: The SSV has been increasingly chosen as the lowest instrumented vertebra to prevent DJK, and some studies have provided supportive results. However, other studies demonstrate that lowest instrumented vertebra located in the FLV has similar DJK incidence with the benefit of saving levels. Materials and Methods: Electronic searches of PubMed, Embase, the Cochrane Database, and Web of Science were performed. Radiographic parameters, incidence of DJK, and revision surgery rates were compared between SSV and FLV groups. The odds ratio (OR) was used to identify differences between the groups and P
