Cannulated Headless Faceted Screws with Single-Use Surgical Instrument Kit
Diamond Orthopedic. The New Fixation Standard in Orthopedics
Diamond Orthopedic bone screws feature an enhanced design where facets are added to screw threads, increasing thread volume, fostering better engagement with neighboring bone, and lowering compressive stress at the bone/screw interface. Compressive stress generated by traditional threads can lead to microfractures, damaged bone, and can create a narrow, high-stress core susceptible to pullout failure. A faceted screw’s ability to generate lower compressive stress at the bone/screw interface brings a new and unique way to address this issue.
- Lower Insertional Torque - The faceted threadform lowers insertional torque required to reduce a fracture by ~50%1
- Increased Bone Contact - Faceted bone screws feature better neighboring bone engagement that leads to increased osteogenesis and bone/device apposition2
- Higher Pullout Strength - Faceted bone screws feature an improved bone/screw interface, increasing fixation and pullout strength, with up to 61% greater pullout strength two weeks after surgery2
Faceted Threadform Technology
The unique geometry of facets reduces friction during the insertion process and uses the naturally occurring viscoelastic properties of bone to achieve more contact at the bone-screw interface. The faceted threadform enables a nearly 50% reduction in insertion torque with less stress transfer and higher pullout strength.1
- Facets create ‘peaks’ and ‘valleys’ on screw threads. 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.
