Nexus Spine’s Tranquil™ interbody fusion technology has reached 5,000 implantations. The milestone spans the company’s entire Tranquil portfolio comprising 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 or teeth that are commonly found on competitive devices.
Compliant mechanisms mimic nature by providing motion and force transmission through bending rather than from traditional sliding joints. This breakthrough enables bio-friendly materials such as titanium to function more like human tissues, at the macro and microscopic levels. This approach utilizes modern mathematical modeling, 3D finite elemental analysis, and 3D printing to drastically improve the way that spinal implants perform. Nexus compliant mechanism-based devices have been implanted in patients since 2015 with the goal of achieving faster healing with less pain and at a lower cost.
Tranquil is a flexible interbody fusion device made of titanium that is shaped and engineered using compliant mechanism principles to behave like spinal trabecular bone by mimicking its stiffness, resulting in a device that is 1/10th the stiffness of traditional competitive interbody fusion implants.
“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.”
