These systems are intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of acute and chronic instabilities or deformities of the thoracic, lumbar, and sacral spine. The screws can be placed in the pedicles in a variety of trajectories ranging from the standard anatomic transpedicular path projected medially toward the ventral vertebral body, to a caudocephalad path sagittally and a laterally directed path in the transverse plane.
Spineology Connex Cross Connector devices are transversely-placed titanium alloy implants that are intended to connect the rod on one side of a spinal construct to the rod on the other side. These devices are manufactured from titanium alloy and are adjustable to allow the surgeon to build an implant system to fit the patient's anatomical and physiological requirements. Connextor devices are intended to provide immobilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of acute and chronic instabilities or deformities of the thoracic, lumbar, and sacral spine.
Spineology ConneX Rod Connector devices are titanium alloy implants that are intended to connect two rods in a spinal construct. These devices are manufactured from titanium alloy and the components allow the surgeon to build an implant system to fit the patient's anatomical and physiological requirements. Connex Rod Connector devices are intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of acute and chronic instabilities or deformities of the thoracic, lumbar, and sacral spine.
The Spineology Power Adapter is an instrument accessory intended to facilitate the preparation and placement of pedicle screws using powered instrumentation as an optional alternative to the existing manual technique. The Power Adapter is intended for exclusive use with Spineology Fortress, Threshold, Threshold V2, and Palisade System surgical instruments.
