Intended Use The Anterior Tension Band (ATB) System is a comprehensive set of implants and instruments designed for anterior stabilization of the lumbar spine. Indications ATB plates are used from L1 to S1, strictly anterior below the b ifurcation, and anterior or anterolateral above the bifurcation for: –– Degenerative intervertebral disc diseases, –– Spinal fractures ( L1-S1), –– Spinal tumours ( L1-S1), –– Pseudoarthrosis and –– Revisions after failed decompression surgery –– that have sufficient, biomechanically table, ventral sups port. Contraindications ATB plates are contraindicated...

Surgical Technique Standard procedure 1. Prepare the vertebrae After exposing the site and insertion of a bone graft or an i ntervertebral disc or vertebral body replacement, free the vertebrae surfaces from osteophytes so that the ATB plate can lie flush on the surface. 2. Select plate size Select the plate size so that the ATB plate bridges the inter ver ebral space including the bone graft, cage, or vertebral t body eplacement (VBR), and the screw holes lie next to the r vertebral endplates. Note: The plate lengths indicate the overall length. Warning: Bending the ATB plates is not...

4. Position the plate Position the plate so that the screws can be introduced close to the vertebral endplates. This maximizes the anchoring in the bone. Warning: –– In the case of a strictly anterior approach to the lumbar spine, the plate must be introduced below the bifurcation of the large vessels. –– When using a sacral ATB plate, the contact edge must lie on the promontory. When the orientation is correct, the engraved arrow points in a cranial direction. –– The angle for introducing screws into the cranial plate holes is 10°. Contrastingly, the screws are guided into the caudal plate...

Surgical Technique Standard procedure Place a fixation pin on the driver, and affix the plate to the v ertebrae through the contralateral cranial drill guide. Lightly tapping in the fixation pin makes it easier to perforate the cortical bone. Repeat the procedure for the remaining plate holes. 8 DePuy Synthes ATB Anterior Tension Band Plate Surgical Te

6. Prepare the first screw hole Optional instruments 389.826 Drill Bit B 3.3 mm with Stop, 2-flute, length 322/40 mm Drill Bit B 3.3 mm, length 248 mm, for Quick Coupling Handle with Quick Coupling Tap for Cancellous Bone Screws B 5.5 mm, length 248 mm Remove the awl from the drill guide inserter. Remove the i nserter together with the drill guide. Alternative: By screwing out the drill guide inserter all the i nstruments can be removed in one step. In the case of hard bone, remove the inserter and awl, but leave the drill guide. Mount the handle with the quick c oupling on the drill bit B...

Surgical Technique Standard procedure 8. Insert screws Required instruments 388.652 Ratchet Wrench with T-Handle, with Hexagonal Quick-Coupling 6.0 mm Screwdriver Shaft, hexagonal 3.5, with Hexagonal Coupling Holding Sleeve, length 193 mm Place the ratchet wrench with T-handle on the hexagonal s crewdriver shaft, and introduce it into the holding sleeve. Take a 5.5 mm screw of the appropriate length and screw it into the prepared hole. Insert the screw up to 3/4 its length. Then pull the holding sleeve upward, and continue to screw in the screw until the screw head is seated in the plate....
