October 23, 2024 – The medical devices industry is constantly evolving, driven by the relentless pursuit of improved clinical outcomes, refined surgical techniques, and maximized cost efficiency. But with so many possibilities, how do we decide which surface technologies are worth the investment?
At the latest OMTEC conference, Brandon Miller, our US Business Development Manager, tackled this very question. He shared valuable insights into the current landscape of surface technologies in the orthopedic sector and the challenges in prioritizing these innovations. Let us explore some key areas where advanced surface technologies could make a significant impact.
The evolving role of Surface Technologies
Contract manufacturers are increasingly at the forefront of innovation in medical devices. As an experienced surface technology provider in the orthopedic field, Lincotek Medical explores the ongoing challenge of determining which surface technologies to prioritize. The focus extends beyond what is merely possible to what is genuinely impactful, both from a clinical and economic perspective.
Advanced surface technologies are being developed with the potential to improve patient outcomes in several key areas:
• Infection Prevention
• Bone Incorporation
• Durability
• Allergy Mitigation
Infection Prevention: A Top Priority
Infection prevention in implantable orthopedic devices remains a critical concern in pre-surgical planning, especially for patients with comorbidities. Surgeons are increasingly considering advanced surface technologies like nano and antibacterial surfaces to address this challenge.
Nano surfaces have shown promise in being antibacterial due to their unique characteristics at the nanoscale. Their increased surface area and reactivity allow them to interact more effectively with bacteria, while certain nanomaterials can release substances that inhibit bacterial growth or disrupt cell membranes. Antibacterial surfaces, often utilizing these nanomaterials, work through various mechanisms such as disrupting cell membranes, releasing antimicrobial agents, or preventing bacterial adhesion.
Bone Incorporation: Enhancing Healing
Porous additive surfaces, which mimic the natural environment of bones, are another area of focus. These surfaces promote cell attachment and migration, which are essential for bone incorporation. By providing a favorable environment for osteoblasts, these surfaces can assist at-risk patients in achieving better outcomes. Additionally, the porous structure supports vascularization, supplying the necessary components for bone tissue, and can be designed to match the mechanical properties of natural bone,offering structural support during the bone remodeling phase.
Durability: Seeking Long-Term Solutions
Durability is a key consideration in material science, especially as the market evaluates the performance of familiar materials like cobalt chrome. New materials are being explored for their potential to offer better long-term clinical outcomes. However, the high manufacturing scrap rate of some new materials can drive up costs, highlighting the need for continued R&D to determine whether these materials can offer viable solutions for implants like total joint replacements.
Allergy Mitigation: Addressing Emerging Needs
As the demand for implants for patients with metal allergies increases, there is growing interest in materials like titanium niobium nitride. Positioned as an option for surgeons seeking allergy-friendly alternatives, these materials, along with ceramics and others, are gaining traction. However, more research is needed to evaluate their mechanical strength, durability, and long-term impact on patients.
The Path Forward
The future of surface technologies in orthopedics holds great promise, with next-generation innovations poised to offer new horizons for both surgeons and patients. At Lincotek Medical, we are committed to refining manufacturing processes, containing costs, and optimizing patient outcomes.
Together with our colleagues, we can drive the industry and technologies forward, ensuring that the most impactful innovations reach the patients who need them most.
