Further study details as provided by Zimmer Biomet:

Primary Outcome Measures:
  • Maintenance of Deformity Correction [ Time Frame: 6 months ]
    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:
  • Decreased Operative Time [ Time Frame: 6 Months ]
    Comparison of Operative times vs. literature

Study Completion Date: January 2014
Primary Completion Date: January 2014 (Final data collection date for primary outcome measure)
Intervention Details:
    Procedure: Surgery
    All subjects will have spinal surgery between the levels of T1 and Ilium using the Polaris Deformity Spinal System
    Other Names:
    • Polaris Deformity Spinal System
    • Trivium Deformtiy Correction System
Detailed Description:
The purpose of this Post Market Surveillance Validation is to document the performance and clinical outcomes of the Polaris Deformity Spinal System & Trivium 3D Spinal Deformity Correction System. We have extended the study tol collect further outcomes data at the 12 month time point.
