What is OsteoAnchor
OsteoAnchor is a new type of surface architecture for improving the lifespan for patients of cementless orthopaedic implants, such as hip and knee replacements. The unique aspect of OsteoAnchor is the multitude of claw features that protrude from a porous lattice and which embed into the patient’s bone during the implantation operation.
These claws prevent small motions of the implant when the patient begins to mobilise, thus allowing the in-growth of hard bone rather than fibrous tissue into the underlying porous substructure. This hard bone in-growth fixes the implant in place for long-term functionality. No other surface coating on the market provides such a secure initial fixation.
Multiple Applications
The technology is shown here applied to hip replacement systems and is particularly relevant for revision hip arthroplasty where the patient’s bone stock is poor, and also for conservative (short) hip stems. OsteoAnchor technology is applicable to other orthopaedic implant devices such as knee, shoulder, ankle, elbow, wrist and finger replacements
Commercialisation Objectives
We are keen to engage with potential investors and business partners interested in licensing or commercialising this high potential technology.
Competitive Advantage
Competing
products include implants with plasma sprayed or beaded coatings and
more recently implants with porous metal coatings such as porous
tantalum. OsteoAnchor technology offers the following competitive
advantages over these coatings:
-
Improved primary fixation, leading to better bone in-growth and reduced incidence of subsidence and/or loosening of the implant.
-
Longer lifetime of the implant in-vivo due to improved primary and secondary fixation.
-
A one step manufacturing process, where the surface architecture is integral to the implant core.
-
Lower total production cost due to the simplified manufacturing process.
-
Higher potential bone ingrowth due to a deeper porous structure.
