Operative Technique General Guidelines Locking Screw Measurement There are four options to obtain the proper Locking Screw length as illustrated below. Correct Screw Selection Select a screw approximately 2-3mm shorter than the measured length to avoid screw penetrations through the opposite cortex in metaphyseal fixation. Add 2-3mm to measured length for bi-cortical shaft fixation. Measurement Options Measure off K-Wire Read off drill bit calibration Conventional direct measurement Measure off the end of drill bit 8
Operative Technique Step 1 – Pre-Operative Planning Use of the X-Ray template (REF 981084) or Plate Trial (REF 702791) in association with fluoroscopy can assist in the selection of an appropriately sized implant (Fig. 1 & 1A). AxSOS Locking Plate System Distal Lateral Femoral Plate TS Scale: 1.15 : 1 Magnification: 15% Ø 5mm Periprosthetic Locking Screw, Self Tapping REF 370110/-120 A-P View 16 Hole 14 Hole 12 Hole M-L View If the Plate Trial is more than 90mm away from the bone, e.g. with obese patients, a magnification factor of 10-15% will occur and must be compensated for. Final intraoperative verification should be made to ensure correct implant selection.

All dimensions resulting from the use of this template has to be verified intraoperatively, to ensure proper implant selection. 10 Hole 8 Hole 6 Hole 4 Hole Left Right REF 981084 Rev. 0 Fig. 1 Fig. 1A Step 2 – Pre-Operative Locking Insert Application If additional Locking Screws are chosen for the plate shaft, pre-operative insertion of Locking Inserts is recommended. A 5.0mm Locking Insert (REF 370003) is attached to the Locking Insert Inserter (REF 702763) and placed into the chosen holes in the shaft portion of the plate (Fig. 2). Ensure that the Locking Insert is properly placed. The inserter should then be removed (Fig. 2A). Note: Do not place Locking Inserts with the Drill Sleeve. Fig. 2 It is important to note that if a Temporary Plate Holder is to be used for primary proximal plate fixation, then a Locking Insert should not be placed in the same hole as the Temporary Plate Holder (see step 6).
