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.

Trephine Technique for Iliac Crest Bone Graft Harvest: Long-term Results.

Study Design: Report of surgical technique and long-term outcome; review of prospectively gathered data and follow-up survey of patient cohort.

Objective: The aim of this study was to review surgical technique for a trephine graft harvest technique and assess perioperative complications/pain, long-term outcome, and patient satisfaction after anterior iliac crest bone graft (ICBG) harvest for anterior cervical fusion.

Summary Of Background Data: Rates of complications and residual pain after ICBG harvest have reduced its utility as a source of autograft for spinal fusion.

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.

Minimally invasive lateral transiliac sacroiliac joint fusion using 3D-printed triangular titanium implants.

Minimally invasive sacroiliac joint (SIJ) fusion (SIJF) has become an increasingly accepted surgical option for chronic SI joint dysfunction, a prevalent cause of chronic low back/buttock pain. To report clinical and functional outcomes of SIJF using 3D-printed triangular titanium implants (TTI) for patients with chronic SI joint dysfunction. A total of 28 subjects with SIJ dysfunction at 8 centers underwent SIJF with 3D TTI and had scheduled follow-up to 6 months (NCT03122899).

Why Lumbar Artificial Disk Replacements (LADRs) Fail.

Study Design: A retrospective review of prospectively collected data.

Objective: To determine why artificial disk replacements (ADRs) fail by examining results of 91 patients in FDA studies performed at a single investigational device exemption (IDE) site with minimum 2-year follow-up.

Summary Of Background Data: Patients following lumbar ADR generally achieve their 24-month follow-up results at 3 months postoperatively.
