Anterior Tension Band (ATB): two level symmetrical plates for lumbar and sacral
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 twodifferent plates. The sacral plates aredesigned for anterior placement across the L5S1 disc 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 great vessels. Both plates are prelordosed and offered in 1- and 2-level configurations with varying plate lengths corresponding to our ALIF spacer heights. To address varying patient anatomy, two level symmetrical plates for both lumbar and sacral plates in lengths from 77 to 109 mm provide the appropriate implant size. The convergent 5.5 mm, dual core, self-tapping screws increase the resistance to pull-out and lock to the plate in a 1-step locking mechanism. A 5.5 mm Ti cancellous locking head screw with 20 mm thread length and templates for all plates have been added to the system.
