Primary Outcome Measures:
  • Maintenance of Deformity Correction [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    The primary outcome measure for this trial will be the percentage of subjects who have maintained their degree of deformity correction within 10% from immediate post-op to the 6 month follow-up visit.


Secondary Outcome Measures:
  • Fusion Success [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    Subjects with radiographic evidence of fusion consolidation

  • Decreased Operative Time [ Time Frame: 6 Months ] [ Designated as safety issue: No ]
    Comparison of Operative times vs. literature
