Operative Technique AxSOS Compression Plates Option 1: Locking Insert Application If an AxSOS Plate is used in a locking mode, pre-operative insertion of Locking Inserts is recommended. A Locking Insert (4.0mm - REF 370002) is attached to the Locking Insert Inserter (4.0mm - REF 702762) and placed into the chosen hole(s) of the plate (Fig. 2). Ensure that the Locking Insert is properly placed. The Inserter should then be removed (Fig. 3). Do not place Locking Inserts with the Drill Sleeve. Fig. 2 Fig. 3 Locking Screw Insertion Locking Screws can be placed in plate holes provided there is a pre-placed locking insert. The appropriate Drill Sleeve is threaded into the Locking Insert to ensure initial fixation of the Locking Insert into the plate. This may also facilitate subsequent screw placement. A 3.1mm (for 4.0 screws) Drill Bit is used to drill through both cortices. Avoid any angulation or excessive force on the drill, as this could dislodge the Locking Insert. The screw measurement is then taken. The appropriate sized Locking Screw is then inserted. Locking Screws should initially be inserted manually to ensure proper alignment. If the Locking Screw thread does not immediately engage the plate thread, reverse the screw a few turns and re-insert the screw once it is properly aligned. To avoid cold welding of the Locking Screws it is strictly recommended to perform final tightening of the Locking Screws with the Solid Screwdriver together with the Torque Limiting Attachment and T-Handle. This procedure is repeated for all holes chosen for locked fixation. Note: Do not apply force or push the screw through the locking hole. By turning the locking screw, it will be pulled through the plate. Doing otherwise may damage the screw and/or plate. Locking Insert Extraction Should removal of a Locking Insert be required for any reason, then the following procedure should be used. Thread the central portion (A) of the Locking Insert Extractor (4.0mm - REF 702767, not included in the Extremity plating System) into the Locking Insert that you wish to remove until it is fully seated. Then turn the outer sleeve/collet (B) clockwise until it pulls the Locking Insert out of the plate (Fig. 5). The Locking Insert must then be discarded, as it cannot be reused. Note: Dense cortical bone should be tapped after initial drilling. Solid Screwdriver Torque Limiter Fig. 4 – 4.0mm Instruments for Final Tightening B A Fig. 5 12 T-Handle
Operative Technique AxSOS Compression Plates Option 2: Intra–Operative Locking Insert Application (Items used in this technique are not included in the Extremity Plating System) If desired, a Locking Insert can be applied in a compression hole in the shaft of the plate intra-operatively by using the Locking Insert Forceps (REF 702968 or 702969), Centering Pin (REF 702673 or 702674), Adaptor for Centering Pin (REF 702675), and Guide for Centering Pin (REF 702671 or 702672). First, the Centering Pin is inserted through the chosen hole using the Adaptor and Guide (Fig. 1). It is important to use the Guide as this centers the core hole for Locking Screw insertion after the Locking Insert is applied. After inserting the Centering Pin bi-cortically, remove the Adaptor and Guide. Second, place a Locking Insert on the end of the Forceps and slide the instrument over the Centering Pin until resistance is felt. Then, push the button on the forceps body to further position the Locking Insert down to the hole. Last, apply the Locking Insert by triggering the forceps handle. Push the button on the Forceps once again to remove the device (Fig. 2). At this time, remove the Centering Pin. Fig. 1 Fig. 2 13
