Large graft windows have been incorporated to provide unimpeded graft site and end plate visualization. The large array of variable and fixed screw options accommodate semi-constrained, constrained and hybrid philosophies, while the plates are pre-contoured to address varying patient anatomy in single and multi-level constructs. Indications The Slimplicity Anterior Cervical Plate System is indicated for use in temporary stabilization of the anterior spine from C2 to T1 during the development of cervical spinal fusions in patients with: degenerative disc disease (DDD) (as defined by neck pain of discogenic origin with degeneration of disc confirmed by patient history and radiographic studies); spondylolisthesis; trauma (including fractures or dislocations); spinal tumors; spinal stenosis; pseudarthrosis; and failed previous fusions. Please refer to package insert (LBL-IFU-005) for complete system description, indications and warnings. 2 IMPLANT FEATURES Slimplicity® Plates • Low Profile Plate (2mm) designed to minimize tissue disruption and post-op discomfort (Figure 1) • Pre-Contoured to address patient anatomy (Figure 1) • Central Graft Windows facilitate unimpeded graft visualization (Figure 2) • Intuitive Single Step Locking Mechanism facilitates secure application (Figure 3) Plate Sizing Lengths 1 Level – 7 sizes, 20-34mm (2mm increments) 2 Level – 7 sizes, 35, 37-55mm (3mm increments) 3 Level – 8 sizes, 54-75mm (3mm increments) 4 Level – 6 sizes, 69-89mm (4mm increments) Width 17mm Figure 1 Figure 2 Waist 14mm Slimplicity Fixed & Variable Bone Screws Variable Screws have a 14° (4.5mm) or 20° (4.0mm) cone of angulation to accommodate preferred screw placement (Figure 4) Fixed & Variable Screw Sizes 4.0 & 4.5mm Diameters 12-18mm Lengths (2mm increments) Figure 3 20° (4.0mm) 20° (4.0mm) Figure 4 3 INSTRUMENTS ACP Plate Bender • Used to create a lordotic or kyphotic bend in the Slimplicity Plate ® • Part Number ACP-003 ACP Bone Awl • Used to create a starter hole for the Slimplicity Drills • Part Number ACP-006 ACP Fixation Pin Note: Not for definitive fixation • Used to hold the Plate in position during Screw placement • Part Number ACP-009 ACP Fixed Drill Guide • Used as a guide for the ACP Drill when utilizing a Fixed Screw • Part Number ACP-005F ACP Variable Drill Guide • Used as a guide for the ACP Drill when utilizing a Variable Screw • Part Number ACP-005V 4 ACP Drill Universal Straight Handle Shown assembled with ACP Drill Guide and 16mm ACP Drill • Used with the ACP Drills • Part Number 04-9024 ACP Drills • Used to prepare a pathway in bone for the Bone Screws • Part Number ACP-012 (12mm) Purple • Part Number ACP-014 (14mm) Gold • Part Number ACP-016 (16mm) Green ACP 2.5mm Tapered Hex Driver • Used to advance Bone Screws through the Slimplicity Plate and secure them to bone ® • Part Number 00-9027 ACP Locking Tool • Used to prevent Bone Screw backout by engaging the locking mechanism • Part Number 00-9021 ACP Lock/ Unlock Tool • Used to prevent Bone Screw backout by engaging the locking mechanism or unlocking the locking mechanism for removal of the Bone Screw • Part Number 00-9023 5 SURGICAL TECHNIQUE 1. Patient Positioning and Approach: The patient is placed on the operating room table in the supine position with the head in slight extension and slight rotation opposite the side of incision. After decompression and interbody grafting procedures have been completed, remove all anterior osteophytes to provide a contoured contact surface for optimum plate positioning. 2. Plate Selection: When selecting the Plate size that best fits the anatomy, it is important to know that the length of the Plate is based on the distance between the ends of the Plate. The Plate should not extend over the adjacent disc spaces. 3. Plate Contouring: The Slimplicity Anterior Cervical Plate is precontoured with lordotic curvature to minimize intraoperative contouring. If the lordotic curvature of the Plate needs to be modified, the Plate Bender may be used for contouring. The Plate should not be contoured through the locking mechanism as it could become damaged. ® 4. Plate Positioning: Position the Plate over the vertebral bodies to be instrumented using a plate holder. Confirm the Plate is properly aligned in mediolateral and caudocranial position. 6 5. Temporary Pin Placement: Plate position can be temporarily fixed using the Fixation Pin and Bone Screw Driver. The Temporary Pin can be inserted through any of the screw holes in the Plate and provides stability during Screw placement (Figure 5). 6. Preparing Screw Hole: In preparing the screw hole, the Awl may be used to create a pilot hole. The Awl is placed in the desired screw hole position with up to 14˚ of angulation. Press and rotate the Awl through the Plate and into the bone until the depth has bottomed out against the Plate. The Awl will provide a pilot hole up to a depth of 10mm (Figure 6). If preferred, the Drill Guide (fixed or variable depending on Screw choice) and Drill can be used to create the screw hole. Attach the Drill Guide to the Plate and drill the screw hole (Fixed Drill Guide if Fixed Screws are desired or Variable Drill Guide if Variable Screws are desired). The Drills are provided in 12, 14, and 16mm lengths with corresponding Drill Guides in both variable and fixed positions (Figures 7 and 7a). Figure 5 Figure 6 Figure 7 Figure 7a 7 SURGICAL TECHNIQUE 7. Screw Insertion: The self-tapping, self-drilling Bone Screws are available in 12, 14, 16, and 18mm lengths in both 4 and 4.5mm diameters. All length and diameter Bone Screw options are available in a fixed and variable head design. Bone Screw lengths measure from under screw head to point. The Bone Screws selected for implantation are inserted using the ACP Bone Screw Driver (Figure 8). Insert the Bone Screw into the vertebrae to be instrumented until it rests firmly inside the plate screw hole (Figure 9). This will enable the Locking Mechanism to be engaged. Repeat the Screw insertion procedure for each screw hole position within the Plate. Figure 8 8. Locking Mechanism: Once the Bone Screws have been properly seated, positioned, and tightened, the Locking Mechanism can be rotated to secure the seated Bone Screws within the construct. Insert the ACP Locking Tool between the two green rivets and rotate 360˚ until the rivets cover both screw heads (Figure 10). Do not rotate rivets more than two times as this will weaken the Locking Mechanism. Secure all Bone Screws with the Locking Mechanism (Figure 11). If desired the ACP Lock/Unlock tool can be used to lock the green rivets individually. Turn the rivet until it is fully engaged as pictured in Figure 11. Figure 9 Figure 10 Figure 11 8 9. Closure: After visual and radiographic confirmation of Plate, Screw, and bone graft placement, the closure process can proceed. The Slimplicity Anterior Cervical Plate System surgical technique is a general guide for instrumentation. The surgeon should be familiar with anterior cervical fusion. ® 10. Screw Removal: Figure 12 If needed, the Bone Screws can be removed using the Lock/Unlock Tool. The Locking Mechanism is rotated back to its unlocked position (Figure 12). Once the rivet has been rotated the Screws can be removed from the construct. 9 SLIMPLICITY IMPLANTS ® 10 Item No. Description ACP120 ACP122 ACP124 ACP126 ACP128 ACP130 ACP132 ACP134 ACP235 ACP237 ACP240 ACP243 ACP246 ACP249 ACP252 ACP255 ACP354 ACP357 ACP360 ACP363 ACP366 ACP369 ACP372 ACP375 ACP469 ACP473 ACP477 ACP481 ACP485 ACP489 SDF4012 SDF4014 SDF4016 SDF4018 SDF4512 SDF4514 SDF4516 SDF4518 SDV4012 SDV4014 SDV4016 SDV4018 SDV4512 SDV4514 SDV4516 SDV4518 Anterior Cervical Plate, 1-Level, 20mm Anterior Cervical Plate, 1-Level, 22mm Anterior Cervical Plate, 1-Level, 24mm Anterior Cervical Plate, 1-Level, 26mm Anterior Cervical Plate, 1-Level, 28mm Anterior Cervical Plate, 1-Level, 30mm Anterior Cervical Plate, 1-Level, 32mm Anterior Cervical Plate, 1-Level, 34mm Anterior Cervical Plate, 2-Level, 35mm Anterior Cervical Plate, 2-Level, 37mm Anterior Cervical Plate, 2-Level, 40mm Anterior Cervical Plate, 2-Level, 43mm Anterior Cervical Plate, 2-Level, 46mm Anterior Cervical Plate, 2-Level, 49mm Anterior Cervical Plate, 2-Level, 52mm Anterior Cervical Plate, 2-Level, 55mm Anterior Cervical Plate, 3-Level, 54mm Anterior Cervical Plate, 3-Level, 57mm Anterior Cervical Plate, 3-Level, 60mm Anterior Cervical Plate, 3-Level, 63mm Anterior Cervical Plate, 3-Level, 66mm Anterior Cervical Plate, 3-Level, 69mm Anterior Cervical Plate, 3-Level ,72mm Anterior Cervical Plate, 3-Level, 75mm Anterior Cervical Plate, 4-Level, 69mm Anterior Cervical Plate, 4-Level, 73mm Anterior Cervical Plate, 4-Level, 77mm Anterior Cervical Plate, 4-Level, 81mm Anterior Cervical Plate, 4-Level, 85mm Anterior Cervical Plate, 4-Level, 89mm 4.0mm x 12mm SD Fixed Screw 4.0mm x 14mm SD Fixed Screw 4.0mm x 16mm SD Fixed Screw 4.0mm x 18mm SD Fixed Screw 4.5mm x 12mm SD Fixed Screw 4.5mm x 14mm SD Fixed Screw 4.5mm x 16mm SD Fixed Screw 4.5mm x 18mm SD Fixed Screw 4.0mm x 12mm SD Variable Screw 4.0mm x 14mm SD Variable Screw 4.0mm x 16mm SD Variable Screw 4.0mm x 18mm SD Variable Screw 4.5mm x 12mm SD Variable Screw 4.5mm x 14mm SD Variable Screw 4.5mm x 16mm SD Variable Screw 4.5mm x 18mm SD Variable Screw SLIMPLICITY INSTRUMENTS ® Item No. Description ACP-003 ACP-006 ACP-009 ACP-005F ACP-005V 04-9024 ACP-012 ACP-014 ACP-016 00-9027 00-9021 00-9023 ACP Plate Bender ACP Bone Awl ACP Fixation Pin ACP Fixed Drill Guide ACP Variable Drill Guide ACP Drill Universal Straight Handle ACP Drill – 12mm ACP Drill – 14mm ACP Drill – 16mm ACP 2.5mm Tapered Hex Driver ACP Locking Tool ACP Lock/Unlock Tool NOTES 12 Precision Spine, Inc. 2050 Executive Drive Pearl, MS 39208 Customer Service: 1.888.241.4773 Phone: 601.420.4244 Toll Free: 877.780.4370 Fax: 601.420.5501 www.precisionspineinc.com Caution: Federal (USA) law restricts these devices to sale by or on the order of a physician.
