It has not been tested for heating, migration or image artifact in the MR environment. The safety of the Low Profile Neuro Plating System in the MR environment is unknown. Scanning a patient who has this device may result in patient injury. Low Profile Neuro Plating System Surgical Technique DePuy Synthes 1

4 LOW PROFILE NEURO PLATING SYSTEM Introduction The aim of surgical fracture treatment is to reconstruct the bony anatomy and restore its function. According to the AO, internal fixation is distinguished by precise reduction, stable fixation, preservation of blood supply, and early mobilization. 1 Plate and screw osteosynthesis has been established and clinically recognized for some time. The Low Profile Neuro Plating System is a cranial closure system that features low plate/screw profile, wide variety of implants, and modular storage options. Warnings: Not intended for use in patients who are not yet skeletally mature. Resorbable fixation products should be considered as an alternative. These devices can break during use (when subjected to excessive forces or outside the recommended surgical technique). While the surgeon must make the final decision on removal of the broken part based on associated risk in doing so, we recommend that whenever possible and practical for the individual patient, the broken part should be removed. Be aware that implants are not as strong as native bone. Implants subjected to substantial loads may fail. Precaution: Surgical implants must never be reused. An explanted metal implant must never be reimplanted. Even though the device appears undamaged, it may have small defects and internal stress patterns which could lead to breakage. 1.

7 SURGICAL TECHNIQUE 1 Select implant Select the appropriate implants depending on use. The Low Profile Neuro Plating System contains a wide variety of plates, burr hole covers, mesh, and screws. Precaution: When using plates, ensure countersink holes are facing upward. 2 Size implant (if required) Instrument Mesh Cutter Implants may be cut and sized to match the patient anatomy. Replace worn or damaged cutting instruments if the cutting function is not adequate. Precautions: Take care to protect soft tissue from trimmed edges. Replace worn or damaged cutting instruments if the cutting function is not adequate. Cut the implant immediately adjacent to the screw holes.

8 Surgical Technique 3 Contour implant (if required) Instrument Universal Bending Pliers (two required) The implant can be contoured to match the patient s anatomy. Precaution: Excessive and repetitive bending of the implant increases the risk of implant breakage. 4 Position implant Instrument Plate Holding Forceps, Locking Position the implant on the desired location using the appropriate plate holder. 1 DePuy Synthes Low Profle Neuro Plating System Surgical Technique

9 Surgical Technique 5 Pre-drill screw holes (optional) Instruments mm Drill Bit, hex coupling, 4 mm stop, 52 mm mm Drill Bit, hex coupling, 6 mm stop, 52 mm mm Drill Bit, Stryker J-Latch coupling, 4 mm stop, 44.5 mm mm Drill Bit, Stryker J-Latch coupling, 6 mm stop, 44.5 mm Precautions: DePuy Synthes recommends pre-drilling in dense bone when using 5 mm or 6 mm screws. Drill rate should never exceed 1,800 rpm. Higher rates can result in thermal necrosis of the bone, soft tissue burns, and an oversized hole to be drilled. The adverse effects of an oversized hole include reduced pullout force, increased ease of screws stripping in bone, and/or suboptimal fixation. Irrigate during drilling to avoid thermal damage to the bone. Handle devices with care and dispose worn bone cutting instruments in a sharps container. Use only a 1.3 mm drill bit for pre-drilling. 6 Secure implant Instruments Low Profile Neuro Cruciform Screwdriver Blade, hex coupling, self-retaining, short Low Profile Neuro Cruciform Screwdriver Blade, hex coupling, self-retaining, medium Screwdriver Handle, hex coupling, small Screwdriver Handle, hex coupling, medium To load the screw onto the blade, place the blade perpendicular to the screw in the module and fully insert the blade into the screw recess. The screw should be securely attached to the blade Screwdriver Handle, hex coupling, large Low Profle Neuro Plating System Surgical Technique DePuy Synthes 1

10 Surgical Technique For optimal plate/screw profile, insert the screw perpendicular to the plate/bone in the appropriate plate hole. If the screw does not obtain purchase, replace it with a blue Low Profile Neuro emergency screw of the same length. Screwdriver shafts are self-retaining. Replace screwdriver shafts if they are worn or damaged, or if retention is not adequate. Precautions: Fully engage the shaft perpendicular to the screw head. Place the 1.6 mm self-drilling screw perpendicular to the bone at the appropriate plate hole. Take care not to over tighten the screw. In order to determine the appropriate amount of fixation for stability, the surgeon should consider the size and shape of the fracture or osteotomy. DePuy Synthes recommends at least three plates when repairing osteotomies. Additional fixation is recommended to ensure stability of large fractures and osteotomies. When using mesh for larger defects, additional screws for fixation are recommended. After implant placement is complete, discard any fragments or modified parts in an approved sharps container. Irrigate and apply suction for removal of debris potentially generated during implantation. 8 DePuy Synthes Low Profile Neuro Plating System Surgical Technique

11 Surgical Technique Notes: Secure the implants to the bone flap before positioning the bone flap on the patient Secure the desired plates to bone flap. 2. Position the bone flap. 3. Secure the plates to the skull. In order to determine the appropriate amount of fixation for stability, the surgeon should consider the size and shape of a fracture or osteotomy. Precautions: DePuy Synthes recommends at least three plates when repairing osteotomies. Additional fixation is recommended to ensure stability of large fractures and osteotomies. When using mesh for larger defects, additional screws for fixation are recommended. After implant placement is complete, discard any fragments or modified parts in an approved sharps container.
