Prospective Trial of Sacroiliac Joint Fusion Using 3D-Printed Triangular Titanium Implants: 5-Year Follow-Up.

Study Design: Prospective, multicenter, single arm study with 5-year follow up.

Objective: To report long-term (5-year) safety, effectiveness, and radiographic outcomes after sacroiliac (SI) joint fusion (SIJF) with 3D-printed triangular titanium implants (TTI) and compare them with solid titanium plasma spray coated implants.

Summary Of Background Data: A large literature base supports minimally invasive SIJF with TTI for chronic SIJ dysfunction.

Prospective Trial of Sacroiliac Joint Fusion Using 3D-Printed Triangular Titanium Implants: 24-Month Follow-Up.

Background: Strong evidence supports minimally invasive sacroiliac joint (SIJ) fusion using triangular titanium implants (TTI) for chronic SIJ dysfunction.

Objective: To report safety and effectiveness of SIJF using a 3D-printed TTI at 24 months.

Methods: SIJF with TTI was performed in 51 subjects.

Prospective Trial of Sacroiliac Joint Fusion Using 3D-Printed Triangular Titanium Implants.

Background: Prior trials provide strong evidence supporting minimally invasive sacroiliac joint (SIJ) fusion using triangular titanium implants (TTI) for chronic SIJ dysfunction.

Objective: To assess the safety and effectiveness of SIJF using a 3D-printed TTI.

Methods: Fifty-one subjects with carefully diagnosed SIJ dysfunction underwent SIJF with 3D TTI.
