Healthcare Industry News: Trabecular Metal Cup
News Release - December 15, 2016
National Joint Registry Analysis Finds Zimmer Biomet Trabecular Metal(TM) Cups Associated with Significantly Lower Risk of Subsequent Revision Due to Infection in Revision Hip ProceduresWARSAW, Ind., Dec. 14, 2016 -- (Healthcare Sales & Marketing Network) -- Zimmer Biomet Holdings, Inc. (NYSE and SIX: ZBH), a global leader in musculoskeletal healthcare, today announced positive outcomes associated with the use of its Trabecular Metal™ Cups in more than 9,500 patients undergoing revision hip arthroplasty. The data, which stemmed from a new report by the National Joint Registry (NJR) for England, Wales, Northern Ireland and the Isle of Man, documented that Trabecular Metal Cups were associated with lower infection rates and a significant reduction in subsequent hip revision rates.
Specifically, the independent analysis conducted by NJR demonstrated the following*:
- Trabecular Metal Cups used in revision total hip arthroplasty (THA) have been shown to be 21 percent less likely to be re-revised due to infection (statistically significant, p-value=0.036).1,2
- For high risk patients with a first revision indication being infection, Trabecular Metal Cups appear to be 35 percent less likely to be re-revised for infection. Due to the limited sample size, this has not reached statistical significance (not statistically significant, p-value=0.108).3
- Trabecular Metal Cups used in revision THA have been shown to be 11 percent less likely to be re-revised for any reason (statistically significant, p-value=0.015).1
"Infection, implant loosening, pain and dislocation are the most common reasons for revision joint replacement surgery," said Dan Williamson, Zimmer Biomet Group President of Joint Reconstruction. "Our Trabecular Metal acetabular devices are designed to meet the long-term performance needs of hip implant patients. The NJR report reinforces their value in significantly reducing hip revision rates in a large clinical patient population and yielding better outcomes in comparison to traditional non-Trabecular Metal implants."
Zimmer Biomet's Trabecular Metal Material is a unique, highly porous biomaterial made from elemental tantalum with structural, functional and physiological properties similar to bone. The material, which features a 100 percent open, engineered and interconnected pore structure to support bony in-growth and vascularization, has been used in a variety of orthopaedic applications for more than 19 years.4
"Infection after orthopaedic procedures has moved into center stage," says Javad Parvizi, M.D., an orthopaedic surgeon at the Rothman Institute at Thomas Jefferson University Hospital in Philadelphia. "Based on recent data from various sources, it appears that Trabecular Metal implants have unique properties that allow them to reduce the incidence of infection after revision total hip arthroplasty. This finding is encouraging and should provide impetus for us to design studies that unravel the exact anti-infective properties of Trabecular Metal implants."

1 According to NJR data from 2003 to 2015 where 9,573 Trabecular Metal and 30,452 non-Trabecular Metal Cups were used in revision THA and based on hazard ratios adjusted by patient gender, age group, and indications (osteoarthritis/non-osteoarthritis).
2 NJR data shows a higher percentage of Trabecular Metal Cups were used with antibiotic bone cement compared to all other non-Trabecular Metal cementless cups.
3 According to NJR data from 2003 to 2015 where 628 Trabecular Metal and 2,114 non-Trabecular Metal Cups were used in revision THA and based on hazard ratios adjusted by patient gender, age group, and indications (osteoarthritis/non-osteoarthritis).
