Stryker Orthopaedics (Mahwah, New Jersey) said it has released its Rejuvenate Modular Primary Hip System, which is designed to help recreate the anatomy and hip biomechanics of individual patients.
The system was developed to optimize anatomic restoration by providing options that offer enhanced stability, proven modularity, and intra-operative flexibility, Stryker said. With a wide range of femoral stem and neck combinations and an extensive range of length, version and offset, the Rejuvenate Modular Primary Hip System is designed to enable surgeons to better personalize the implant to a patient's unique anatomy, the company noted. By more closely matching the biomechanics of the patient, surgeons may reduce the risk of dislocation and leg length discrepancies, which can be associated with costly hospital readmission and revision surgery, Stryker said.
"Every patient's anatomy and lifestyle are different, which is why we have invested in developing cost-effective personalized hip solutions," said Bill Huffnagle, VP and general manager of Hip Reconstruction at Stryker Orthopaedics. "With the Rejuvenate Modular Primary Hip System, patients can rest assured that their surgeons have the equipment to help them more closely match their specific biomechanical needs."
The Rejuvenate Modular Primary Hip System's modular implant design accommodates most well-established surgical approaches and helps to promote intraoperative efficiency and flexibility, according to the company. Further, the instrumentation used in conjunction with the System is designed with enhanced ergonomics and can more easily be integrated with Stryker's current navigation technology, thereby having the potential to streamline surgical workflow, Stryker noted.
Jonathan Sacks, product manager for Hip Marketing at Stryker Orthopaedics, said in an e-mailed response to Medical Device Daily's questions that the Rejuvenate Modular Primary Hip System potentially offers patients a better range of motion than other products on the market, and the materials used to create the system allow for enhanced durability.
"The Rejuvenate modular design allows surgeons to better personalize the biomechanics of a patient's hip replacement by offering the ability to independently size the femoral canal and neck," Sacks said. "The Rejuvenate Modular Primary Hip System may allow for greater operating room procedural efficiency by potentially eliminating a trial reduction step after broaching and allowing immediate trialing off the definitive femoral component. Its intra-operative flexibility allows surgeons to adjust biomechanics relative to final implant seating and positioning. Its modular neck allows easy access to the acetabulum and provides the ability to prepare the femur prior to acetabular preparation."
Sacks also noted that this new hip system is integrated with the company's latest version of its Navigation software, allowing surgeons to utilize the benefits of computer assistance in personalizing the biomechanics of the patient's hip.
"Additionally, Stryker is committed to personalized solutions with the development of three additional anatomic products, designed to better match natural anatomy. These products are set to be released in the next 12 months," Sacks said.
There appears to be a trend in the industry towards personalized orthopedic solutions and Stryker is not alone in its efforts to offer orthopedic surgeons and their patients more personalized treatments.
When asked about competing products that offer similar benefits, Sacks said that this new hip system from Stryker holds "key advantages over the few competitor modular hip systems on the market today such as enhanced stability, proven modularity and intra-operative flexibility."
He said he anticipated this new system to have a quick adoption among orthopedic surgeons. "The Rejuvenate system is consistent with the hip systems that surgeons are comfortable using, while offering more flexibility than a traditional monolithic stem. We are also able to address concerns surgeons may have by explaining the material selection, manufacturing process, and rigorous development testing behind Rejuvenate," he said. "This new hip system helps surgeons to better address the changing patient demographics (bone morphologies) as increasingly younger patients get total hip replacements."
One company that is particularly well known for patient-specific orthopedic implants – at least where the knee is concerned – is ConforMIS (Burlington, Massachusetts). In December the company launched a new iteration of its unicompartmental knee-resurfacing device, the iUni G2 (Medical Device Daily, Dec. 15, 2009). ConforMIS has strived to set itself apart from the competition by offering patient-specific knee resurfacing implants designed to offer osteoarthritis patients a more customized fit based on measurements obtained from a CT scan (MDD, Feb. 28, 2008 and April 4, 2008).
ConforMIS, a private company, has been rather successful at raising funds too. In July it reported raising $50 million – its largest round of funding to date – from private-equity and sovereign-wealth funds in the U.S., Asia, Europe and the Middle East. ConforMIS reached this milestone in June, in a process that began in 2008, the company said at that time (MDD, July 13, 2009).
