Anterior Tension Band System (ATB)
The Anterior Tension Band System is a low-profile anterior plating system designed to provide additional fixation across ALIF constructs thereby avoiding a posterior procedure and reducing tissue resection and operative site morbidity.
The system consists of two different plates. The sacral plates are designed for anterior placement across the L5S1disc space utilizing a step procedure for easy placement on the sacral promontory. The lumbar plates can be placed either directly anterior or anterolaterally from L1L5 depending on the location of the bifurcation of the great vessels. Both plates are pre-lordosed and offered in 1- and 2-level configurations with varying plate lengths corresponding to our ALIF spacer heights.
The plate may also be used in conjunction with posterior instrumentation if a 360 fusion is required.
The convergent 5.5 mm screws, dual core, self-tapping increase the resistance to pull-out and lock to the plate in a 1-step locking mechanism. The top surface of the final rigid construct is completely smooth to avoid soft tissue irritation.
