First U.S. Surgeries with 4WEB’s 3D Printed Lateral Spine Truss System

4WEB Medical, developer of 3D printed implant technology, announced the first surgeries utilizing the company’s Lateral Spine Truss System were recently performed in several notable hospitals in the United States. The company’s lateral interbody fusion device was designed to solve known surgical problems associated with legacy annular implant designs and represents a significant advancement in lateral access surgery.
 
“4WEB’s spine truss implants have proven to be very effective in providing excellent surgical outcomes for my patients,” said Frank Cammisa, M.D., Hospital for Special Surgery, New York, N.Y. “In contrast to older ring-shaped implants with hollow cores, 4WEB’s truss implant web structure spans the entire endplate providing strong initial fixation and minimizing subsidence.”
 
The Lateral Spine Truss System is designed with a unique bi-convex dome that distributes load across a larger surface area and has three times more textured surface topography when compared to other competitive spine implants. The key differentiator for the product, though, is its proprietary truss design and the performance it lends to driving successful spine fusion results.
 
“A recent study comparing 4WEB’s lateral truss implant to a ring implant design demonstrated that the truss design had superior resistance to subsidence,” said John Peloza, M.D., Center for Spine Care, Dallas, Texas. “In fact, the 40mm length truss implant displayed 61 percent greater resistance to subsidence than the 60mm length ring implant¹. These results are indicative of the optimized load distribution inherent to 4WEB’s truss implant technology that maximizes endplate contact while providing an open architecture for bone formation and fusion.”
 
4WEB Medical is an implant device company founded in 2008 in Dallas, Texas. Thirty years of research in topological dimension theory led to the discovery of a novel geometry, the 4WEB, that can be used as a building block to create high-strength, lightweight web structures. The company leveraged this breakthrough along with cutting-edge 3D printing technology to develop 4WEB Medical’s proprietary truss implant platform. The 4WEB Medical product portfolio includes the Cervical Spine Truss System, the ALIF Spine Truss System, the Posterior Spine Truss System, the Lateral Spine Truss System, and the Osteotomy Truss System. 4WEB is actively developing truss implant designs for knee, hip, trauma, and patient specific orthopedic procedures.
