The ‘peaks’ serve as the initial area of bone/screw contact during insertion, which reduces friction and results in ~50% less torque required for insertion.
Immediately following insertion, bone relaxes into facet ‘valleys,’ enabling greater bone/screw contact than the typical helical screw
Facets bring a “volumetric advantage,” with thread valleys holding up to 20% more bone volume, enabling greater pullout strength and toggle performance.
The faceted thread's unique design reduces friction during insertion. Facet 'valleys' serve as a bone stress relief mechanism, resulting in ~50% lower insertional torque and less potential for microfractures and necrosis.
After insertion, the facet "valleys" also promote restoration of bone against the screw flanks, creating a firm grip that increases fixation and retention strength, and reduces post- insertion compressive stress. Faceted screws distribute the load over a greater volume of bone and significantly increase the peak pullout load.
Rigorous testing conducted at Orthokinetic Testing Technologies demonstrated that faceted screws deliver improved fixation integrity. There is significantly less risk of screw loosening due to cyclic loading compared to the standard helical screw. The faceted screw also provides 61% greater pullout strength within 2 weeks of surgery providing the best fixation for patients.

We're proud to create optimized porous architecture designed for osseointegration with TIDAL Technology™.
State-of-the-art technology like diamond ortho screws, osteotomy wedges, Kinos Axiom® Total Ankle Replacement System, osseoREBAR™ nails, and cervical fusion cages create our orthopedic systems. Our products unite 3D printing, biomaterials, biomechanics, and artificial intelligence to offer some of the best implant and fusion solutions in the industry.
The Kinos Axiom® Total Ankle System, featuring TIDAL Technology, is the first biomechanically accurate implant providing motion in all three anatomic planes mimicking the movement of a natural healthy ankle. Interchangeable with both flat-cut and chamfer-cut talar implants, the product was designed to help patients who are experiencing pain due to ankle arthritis by replacing the ankle joint with a prosthesis. With a Kinos Axiom® Total Ankle, patients can experience a reduction in pain, better alignment, and increased movement in the new joint.
Designed for use in anterior cervical discectomy and fusion procedures, the TIDAL® Cervical Fusion Cage features our proprietary porous technology that encourages enhanced fusion. The cage is available in multiple heights and footprints to accommodate different patient anatomies and paired with sterile packed, disposable instrumentation.
Our robust Foot & Ankle Wedge portfolio contains implants designed for internal bone fixation for fractures and osteotomies in the ankle and foot. This wedge family includes Anatomic Cotton and Evans Wedges, Standard Cotton Wedges, and Subtalar Wedges that are manufactured using laser powder bed fusion of medical grade titanium alloy featuring our proprietary TIDAL Technology™ that encourages better fusion.
