5 SI joint fusion updates

Sacroiliac joint fusion technology is advancing, and the data shows it’s efficacy across different medtech companies.

Five notes:

1. Tenon Medical earned FDA 510(k) clearance to use its Catamaran sacroiliac joint system for augmenting thoracolumbar fusion. The indication was first used in June by Andrew Trontis, MD.

2. A new study found that Aurora Spine’s SiLO TFX sacroiliac fusion system saw stronger outcomes compared to traditional posterolateral transosseous techniques.​ The clinical study, published in Neurospine, found SiLO TFX removed less bone volume and offered a larger surface area for bony fusion compared to the posterolateral transosseous technique, according to an April 2 news release from the company. The system also maintained the bone-implant interface upon fatigue loading in all specimens.

3. Aurora Spine’s SiLO sacroiliac joint fusion system surpassed 2,500 procedures in the U.S. The SiLO platform includes the SiLO-TFX system and uses a posterior approach to secure transfixation across the SI joint.

4. Spinal Simplicity launched its Patriot-SI standalone posterior sacroiliac joint fusion implant. The implant is made from 3D-printed titanium alloy and is fully hydroxyapatite-coating.. Patriot-SI is the only fully cannulated posterior system of its kind and lets surgeons deploy it over a guidewire.

5. New data published in the Journal of Spine Surgery notes that fully threaded screw technology surpasses triangular implant design for sacroiliac joint fusion by 300% in fixation strength.
