The late 1980s and 1990s represented a major transition period for medical plastics. Major resin producers were scared off by litigation issues following failures of silicone implants. At the same time, markets such as catheters were just emerging and needed development partners.
The performance capabilities of orthopedic implants can be significantly increased by utilizing enhanced polymers that have been precision blended with additives using specialized processes and equipment. Long term implantable and bioresorbable polymers are enhanced with radiopaque fillers, bioactive bone growth additives and active pharmaceutical ingredients (API). These enhancements can increase therapeutic effect and reduce side effects, but special equipment and processes are required to realize their full potential.
