Wisconsin Patent of the Month – August 2023

Orthopedic implants are in a constant evolution as the industry works to find the best ways to correct skeletal defects. Titan Spine, Inc. is committed to this innovation, transforming the way orthopedic implants integrate with bone tissue, ushering in a new era of rapid and high-quality osseointegration. The secret lies in their osteoinducting bone-contacting surfaces, which have the potential to revolutionize the field of orthopedics and improve patient outcomes.

Titan Spine’s novel approach involves a multi-step process that combines additive manufacturing with precise mechanical and chemical erosion techniques. This meticulous process results in orthopedic implants with micro-scale and nano-scale structures on their bone-contacting surfaces. These structures create an osteoinducting roughness that significantly enhances bone integration, stimulates mesenchymal stem cell differentiation, promotes preosteoblast maturation, and accelerates new bone growth. What’s even more remarkable is that this enhancement is far superior to existing surfaces commonly used in orthopedic implants.

These orthopedic implants are additively manufactured using cutting-edge techniques like electron beam melting and selective laser sintering. This allows for precise control over the implant’s structure and the introduction of the osteoinducting roughness.

Once the implant is manufactured, a carefully orchestrated mechanical and chemical erosion process is employed. This process imparts the unique micro-scale and nano-scale structures onto the bone-contacting surfaces, ensuring that the implant achieves optimal integration with bone tissue. The result is a friction-type grip that enhances osseointegration without causing damage to the bone.

Are you developing new technology for an existing application? Did you know your development work could be eligible for the R&D Tax Credit and you can receive up to 14% back on your expenses? Even if your development isn’t successful your work may still qualify for R&D credits (i.e. you don’t need to have a patent to qualify). To find out more, please contact a Swanson Reed R&D Specialist today or check out our free online eligibility test.
