LINEAGE® Ceramic-on-Ceramic Total Hip Arthroplasty IDE Study In April 1997, an FDA Investigational Device Exemption (IDE) study was
begun to determine the effectiveness of Wright's LINEAGE®
ceramic-on-ceramic hip system. By November 2003, nearly 1700 implants
were in place, making it the largest regulated study ever on a total hip
replacement device.
Data collected over the last six years shows that the ceramic implant is
more durable and has fewer complications than traditional metal and
polyethylene implants. Because of such outstanding performance results,
the study concludes that the LINEAGE® system is both safe and effective.
