SPARTAN Study: 6-Month Interim Results
The SPARTAN Study is a prospective, multicenter, post-market surveillance study on a Modular SI Joint Fusion System, designed to assess patient-reported pain and functional outcomes following lateral-oblique SI joint fusion with the TransLoc 3D System. Interim findings from the SPARTAN study summarize patient-reported changes in pain and function at 6 months.
SPARTAN
Study Overview
To evaluate the safety and clinical outcomes associated with the TransLoc 3D system, an ongoing prospective, multicenter study is collecting patient-reported pain and functional outcomes.
Interim 6-month findings present observed changes in pain and function to date, with no device- or procedure-related adverse events reported through the 6-month follow-up period.
