Plate system for distal femur and proximal lateral tibia. Anatomically precontoured low profile plates — Reduced soft tissue problems — No need for plate contouring Note: Excessive and repetitive bending is not recommended as it may weaken the plate. Instrument assembly 1 Choose the matching guiding block and place it onto the plate head. Make sure that the three-point locking mechanism is positioned on the pre-contoured reference points of the plate. A 3 To lock the LCP drill sleeve tighten the locking nut of the guiding block by turning it clockwise. Synthes 5.

Page 5 LISS instrumentation for Stardrive and Hex drive The torque-limiting screwdriver, the screwdriver shaft and the cleaning instrument are available for screws with Stardrive and Hex drive. DePuy Synthes Page Preoperative Planning Page 11 6. Determine the screw lengths for the screw holes A to G using the table below. Length of locking screws mm Hole Page 12 The real condyle width RCW is therefore 83 mm. The screw lengths are therefore: Screw hole Screw length mm Important: The proper placement of the plate on the condyle is essential to ensure the correct screw length.

This also reduces the traction force of the gastrocnemius muscle. Page 15 LISS instruments. Then, screws can be inserted by applying the technique described in the LCP Instructions for Use Insert the fixation bolt in hole A of the insertion guide. Place the insertion guide on the three-point locking mechanism of the plate. Page 16 Note: To prevent tissue ingrowth and facilitate implant removal, close the unoccupied screw holes with screw hole inserts prior to inserting the plate.

Use the torque-limiting screwdriver. The optimum torque is reached after one click. Page 17 Intra-articular fractures In intra-articular fractures, an anterolateral arthrotomy provi- ding good control of the reduction is recommended. This arthrotomy also allows a subsequent insertion of the plate and can be used to insert lag screws from medially.

This occurrence is also visible in the AP view of an image intensifier. The plate must lie flat up against the condyle to ensure an optimal fit on the bone. Page 20 Carefully check the position of the plate and the length of the reduced injured limb. Once the reduction has been successfully completed and the plate has been positioned correctly, the locking screws can be inserted. Page 21 Once the correct position is deter- mined, the plate can be locked temporarily with a Kirschner wire through the fixation bolt.

Note: The aiming device can be used from hole 3 to hole Page 22 Then insert a screw in the proximal fragment. Important: If a screw has to be removed and reinserted, use the torque-limiting screwdriver and not the power tool. Page 23 The pulling device helps to solve this problem see page Page 24 Kirschner wires, leaving the centering sleeve in place, and round down to the nearest screw length.

This will ensure that the tip of the screw will not protrude through the me- dial cortex. Page 25 LISS insertion guide. To insert the screw, start the power tool slowly, increase the speed and then reduce it again before the screw is fully tightened. Advance the screws into the bone until the second bulge of the screwdriver dis- appears in the drill sleeve.

After reconnecting the screwdriver to the power tool, withdraw the screwdriver from the screw. Page 27 Drill Bit 4.

Carefully drill the screw hole using the 4. Page 29 LISS insertion guide. Page 30 Torque-limiting Screwdriver Stardrive, T25 Insert a stopper into the LISS insertion guide after screw insertion.

Page 31 Page 32 Read the drilled depth directly from the laser mark on the drill bit. Remove both drill bit and drill sleeve 7. Note: Replacement stop rings can be ordered from the local Synthes representative. Page 33 — If the measured drill depth is shorter than 8 mm, do not use periprosthetic screws.

Page Option: Pulling Device "Whirly Bird" Note: It is important to monitor the advance of the screw tip carefully when inserting the pulling device. Stop the power tool before the pulling device is seated on the plate. Failure to do so may result in stripping the thread in the bone. Page Implant Removal see step 1 on page Make stab incisions and use the torque-limiting screwdriver to unlock all screws manually. In a second step, completely remove all screws with a power tool.
