SALT LAKE CITY/October 11, 2022 — Nexus Spine announced that its Tranquil™ interbody fusion technology produced with additive manufacturing has reached 5,000 implantations. The milestone spans across the company’s entire Tranquil™ portfolio consisting of cervical, cervical with integrated fixation, ALIF, ALIF with integrated fixation, PLIF, TLIF, Steerable TLIF, and DLIF configurations. Tranquil™ interbody devices are made of titanium and are engineered using proprietary compliant mechanism principles to flex and match the stiffness of spinal trabecular bone to encourage rapid integration and stability while minimizing the potential for subsidence. The matched stiffness is consistent throughout Tranquil™ implants due to the lack of outer frames and/or teeth that are commonly found on competitive devices.
“Existing interbody fusion devices are too stiff,” commented David Hawkes, President of Nexus Spine. “An overly stiff interbody creates areas of stress shielding that impede bone development and delay healing. Others seem to be focused on surface technology, but surface topography is meaningless if the stiffness of the implant is wrong. Through compliant mechanism engineering, we are able to appropriately, and precisely match the stiffness of Tranquil™ to cancellous bone. This creates a safe zone of mechanical loading that promotes bone formation and stability through more rapid implant integration with the vertebral endplate. Our proprietary surface treatment also plays a role, but it takes a back seat to matched stiffness. We are excited that more than 3,000 patients have benefited from Tranquil™.”
The company’s line of Tranquil™ interbody fusion devices will be featured at booth #4233 at the North American Spine Society Annual Meeting October 12-14, along with its PressON™ posterior fixation system. The booth will feature interactive demonstrations that highlight the advantages of the company’s technologies, compliant mechanisms, and the shortcomings of competitive systems.
