Dynamic Anterior Cervical Plating System • Internally dynamized • Low 2.5mm profile • Graft and endplate visualization

Open the catalog to page 1

Table of Contents Introduction DynaTran® is an internally-dynamized anterior cervical plating system that is designed to allow axial settling while reducing the risk of plate impingement on adjacent discs. With an integrated one-step screw locking mechanism, DynaTran® maintains a low 2.5mm profile across the entire surface of the plate. The uniquely-shaped graft windows enable both graft and end plate visualization to facilitate screw placement. The system offers custom distraction pins that allow DynaTran® plates to be positioned with the pins still in place to facilitate plate alignment...

The DynaTran® ACP System offers a low profile, internally dynamized plate with a variety of screw options. The system is designed to provide up to 2mm of translation per level. The plate is inserted with the plate clips in place. After the screws are implanted, the plate clips are removed to allow the plate to close, as graft settling occurs. Plates are implanted with clips in place After screws are implanted, clips are removed The plate can also be inserted with one or more of the clips removed, so that those levels are in the closed position (see picture). In this way, the plate acts as...

System Overview Patient Positioning and Exposure Both fixed and variable screws are offered as self-tapping, which feature a cutting flute and a less aggressive screw tip, and self-drilling, which have been designed with a sharp tip for insertion without prior drilling. Self-tapping screw The patient is placed in a supine position with the head turned slightly away from the side of the approach. For one- or two-level procedures, a transverse incision parallel to the skin creases of the neck is recommended. The left side is preferred, as the more constant course of the recurrent laryngeal...

Screw Hole Preparation Each plate has been pre-assembled with one plate clip at each internal segment. These clips are designed to keep the plate in the extended position for easier screw insertion. The plate clips can be assembled with the hook facing either to the right or to the left to support the surgeon’s surgical approach. If the hook is positioned to the right (to support a right-sided approach), the text “REMOVE” would be facing upsidedown. Note: The following instruments are found in the Reflex® Hybrid set. Depending on the type of a screw selected for a particular procedure, the...

Screw Hole Preparation Drill Guide Handle Screw Type Variable Angle Fixed Angle Bone Screw Insertion While certain instruments – such as the awl, drills, tap, and the screwdrivers – are used for all types of bone screws, the drill guides and punch awl must correspond to whether fixed or variable angle bone screws will be implanted. The variable and fixed angle guides can be identified by their blue and purple handles, respectively. The punch awl handle is not screwspecific; however, the fixed and variable angle awl sleeves can be identified by the appropriate laser marking. Both the fixed...

Bone Screw Insertion Open Bone Screw Insertion As an alternative to a drill guide, the punch awl may be used to center and direct the pathway of the selfdrilling screws. Interchangeable fixed or variable sleeves (identified by the appropriate laser marking) are threaded onto the punch awl shaft, and are designed to seat into the screw hole in the plate. As with the single-barrel drill guide, the punch awl will provide the correct range of angulation for both fixed and variable screws. Do not use the punch awl without a sleeve. Following screw hole preparation, select the appropriate screw...

Bone Screw Insertion Bone screws can also be placed using the collet screwdriver, which features a self-centering pin and a sleeve to hold the screw head securely. The third option for screw insertion is the insertion screwdriver, which features a tapered tip in combination with a small nitinol holding pin for a secure hold of the screw head. Ensure that the collet sleeve is in the open position by pulling it toward the driver handle. Utilizing the screw caddy as a base upon which to load the screws, insert the self-centering pin of the screwdriver into the cannulated head of the bone...

Bone Screw Removal The compressor is designed to facilitate pre-compression of the graft. After removing distraction pins, place one arm of the compressor in a key hole of one segment, and the second arm of the compressor against the opposite end of the plate for 1 and 2-level plates. For 3 and 4- level plates, the opposite end of the instrument can also be placed in between key holes of other levels. The compressor is designed to allow one segment to be compressed at a time. Compress instrument until you feel resistance. Avoid excessive compression. Note: This device is not to be used...

Bone Screw Removal The revision driver may also be used to remove bone screws that have been locked to the plate. The revision driver has a narrow tip that helps to bypass the locking ring and engage the bone screw. The draw rod allows for rigid attachment of the screw to the revision driver. Do not pull the screw out with only the inner shaft/ draw rod. Note: Do not utilize the revision driver as an insertion driver. To begin removal of the screw, insert the draw rod into the inner cannula of the bone screw. Fully seat the cruciform head of the revision driver into the cruciform of...
