US Market Report for Orthopedic Navigation Systems 2017 - MedCore
The majority of IGS cross-platform systems have orthopedic capabilities, but very few are sold outright for use in orthopedics. Many companies who were once very active in this market still manufacture their system but do not actively market and promote sales unless clients directly ask for upgrades. IGS systems are not standard of care in orthopedics, unlike in neurosurgery. This is due to competing technologies, such as patient-specific cut blocks, which also incorporate pre-operative imaging, as well as pressure sensors. Cut blocks saw a rise in popularity and adoption for several years; however, some hospitals have found IGS systems to be more cost-effective, and this alternative has not been considered as much of a competitor since 2014. Robotic systems are also expected to create competition, with companies such as Stryker beginning to sell these systems alongside traditional ones. However, the high price and recent appearance of this technology will prevent it from entirely displacing non-robotic navigation in the near term. Surgeons who have adopted navigation systems for orthopedics generally keep using the system due to clinical benefits, such as reduced revisions. However, surgeons who prefer other technology argue that navigation systems are too cumbersome, too expensive and the added costs do not outweigh the benefits over the other technologies. Nevertheless, the complexity of TKA and THA procedures means that navigation technology can provide concrete clinical and economic benefits.
Orthopedic image guided surgery (IGS) systems are used in procedures such as total knee arthroplasty (TKA), total hip arthroplasty (THA), anterior cruciate ligament (ACL) reconstruction, trauma and corrective surgeries. During these reconstruction procedures, the alignment of the orthopedic implant is critical and IGS systems are capable of reaching the target alignment within 3, 95% to 98% of the time.
