Allo-TEQ · LINQ
A non-piercing, structural bone allograft placed posteriorly through a 1″ drill-less incision. Its large graft window can be packed with DBM filler.
Posterior SI joint procedures.
Without the drill.
One drill-less approach that travels everywhere care happens — office, ASC, and OR. Backed by 16+ peer-reviewed publications.
The portfolio · 01
Allograft options for posterior SI joint procedures, all placed through one drill-less approach in every clinical setting.
Allo-TEQ · TRAQ
A cortical-piercing, structural bone allograft that engages the sacral and iliac cortices through the posterior approach. Its large graft window comes pre-filled with a cancellous plug.
The data · 03
Posterior SI joint procedures are

LINQT RCT
Multicenter · randomized · open-label
200 subjects randomized 2:1 to LINQ versus conservative medical management across 15 U.S. sites. Composite responder primary endpoint at 6 months; follow-up through 24 months.
TRAQTION Study
Prospective · multicenter · post-market
Up to 100 subjects across 10 U.S. sites with 24-month follow-up — evaluating the real-world experience with TRAQ.
Reimbursement · 04
Two codes, two distinct procedures.
Whether the device placed pierces the cortices and engages bone with intrinsic fixation determines the code. Rates, settings, and Medicare coverage by state are on the reimbursement pages.
CPT code
27278
Arthrodesis, sacroiliac joint, percutaneous or minimally invasive, including imaging guidance, unilateral; placement of intra-articular structural bone graft, metal and/or synthetic device(s) without cortical piercing, including use of osteopromotive material and/or obtaining bone graft, when performed.
CPT code
27279
Arthrodesis, sacroiliac joint, percutaneous or minimally invasive, including imaging guidance, unilateral; placement of transarticular and/or intra-articular device(s) that engage bone with intrinsic fixation (eg, screw[s], flange[s], blade[s]) piercing the lateral cortex of the sacrum and the medial cortex of the ilium (with or without piercing the lateral cortex of the ilium), including use of osteopromotive material and/or obtaining bone graft, when performed.
Coverage, coding, and payment are determined by individual payers and may vary by geography, plan, and patient; coverage of 27279 in the office is not yet known.
