neoWave™C is a 3D-printed interbody fusion device featuring its repeating waveform matrix technology that is designed to support postoperative osseointegration while uniquely diffusing compressive loads to reduce device stiffness and, therefore, the risk of subsidence. The proprietary waveform technology also functions to disperse loads during device malleting to meet the mechanical strength demands of implantation.
Features:
- MACRO STRUCTURE: neoWave™ consists of a 3D-printed consistent waveform matrix that reduces stiffness and provides a load-dispersing Snowshoe Effect™ to lessen the potential for implant subsidence. This uniformly-porous architecture contributes to a device stiffness that is comparable to the material stiffness of cortical bone and PEEK while increasing bone graft volume and providing a lattice for bone ingrowth.
- MICRO SURFACE:The proprietary micro roughness of the neoWave™ surface has been shown to be favorable for bone attachment and ongrowth.1 The novel surface design, manufacturing, and post-processing techniques all contribute to the beneficial environment for cellular proliferation.
- NANO SURFACE:Cellular response to a material’s nano surface characteristics plays an important role in overall bone apposition and proliferation.3 The proprietary nanotopography of the neoWave™ surface has been shown to support rapid cellular attachment, communication, and propagation.1
- Strength Under Impaction:The patented neoWave™ matrix uniquely dampens impaction loads providing exceptional mechanical integrity to withstand forces during implantation, which has been found to be problematic for some competitive 3D-printed devices.4 In this video, the same sample was impacted into four locations with over 70 aggressive mallet strikes with no visible fractures or deformations and no visible wear debris or flaking.
- Stiffness Profile: Most titanium cage designs require solid framework in order to meet the mechanical demands during insertion and postoperative loading. These structures increase stiffness and create loading “hot spots” that can promote subsidence. neoWave™ features a proprietary uniform matrix that decreases stiffness and allows the implant to evenly deflect under compressive loads to mimic a more natural bone-like response.Engineering mechanical modeling has shown machined titanium to be up to 13x stiffer than neoWave™.5
- Structural Waveform: The proprietary neoWave™ matrix is comprised of a repeating pattern of internal wave-shaped structures that contributes to the reduction in device stiffness yet enhancement of structural strength and durability. Many competitive 3D-printed implants require solid framework to overcome their structural integrity deficiencies.
- Subsidence vs. Graft Surface Area: Historically, many interbody manufacturers have attempted to increase internal bone graft volumes by thinning the outer walls of the implant at the cost of concentrating compressive loads over a smaller contact area, which increases the chance for subsidence.The neoWave™ matrix solves this problem by uniformly spreading compressive forces throughout the implant while maintaining substantial bone graft volume.Testing has shown that neoWave™ reduces subsidence by 31% at peak loads despite a 29% greater amount of bone graft volume compared to a PEEK interbody implant of an identical footprint.
- Cellular Response: Surface topography at the micro and nano levels have been shown to play an important role in cellular attachment and the creation of an environment conducive to bone growth.3 A cellular response study conducted by distinguished Professor Bill Walsh at the Surgical and Orthopaedic Research Laboratory found that the proprietary neoWave™ surface topography supported rapid cellular attachment and bone cell proliferation.
