Special Instrument

The aiming arm

Assists in positioning the distal screws in the medial plate to help to ensure optimal support for the distal articular block

• Connect the aiming arm to the medial plate• The target of the drill is guided 1,5mm

above the peak to prevent damaging the drill

• Connection of the targetingdevice to the medial plate.

The target of the drill is guided1,5mm above the peak to preventdamaging the drill

• Positioning the medial plate on the medial condyle of the distal humerus

• First steps

Operational Technique

15

• Inserting the K-Wire or Ø 2.0mm drill for primaryfixation of the plate

• Drill the oblong hole Ø 2,5mm tofix the plate and pull the plate tothe bone with a standard screw

Elbow system / Medial Plate

16

• A standard screw can pull the plate to the bone

• 3.5/2.7mm depth gauge tomeasure screw length (not on picture) and then insertion ofthe screw

Elbow system / Medial Plate

17

• The targeting device can now beremoved and the counter nut canbe turned to the top position.

• Now the drill guide withmeasuring option can be fixed

Elbow system / Medial Plate

18

• Drill for Ø2,7mm locking screws

• Read off the depth on the drillguide for appropriate screw length

Elbow system / Medial PlateDrill guide is marked with twomeasurement options

1. 10-42mm (2mm steps)2. 45-75mm (5mm steps)

19

• After fixing the first locking screw, the targeting device drill guide canbe removed

… and a screw can be placed wherethe targeting device was

Elbow system / Medial Plate

20

• Now the other screws can be inserted. The option of LOQTEQ compression in the shaft can be used.

21

• The dorsolateral plate andthe placement of the jointnear screws is shown here. The optimal placementwould bring the screws in between each otherwithout interference.

• It is important to make surethat both plates are in different lengths to avoidstressing the bone and therisk of an additional fracture.

22

• Please check thepositioning under X-Ray and reposition ifnecessary

Elbow system / Dorsolateral Plate

• Positioning of the plate at least 3mm above the joint line to preventplacement into the articular surfaceof the radius

23

• Preparing the insertion of thestandard screw Ø 3,5mm

• Drill and measure with depthgauge

Elbow system / Dorsolateral Plate

24

• Insertion of 2.7mm distal screws

Elbow system / Dorsolateral Plate

25

• Insertion of screws and 3.5 shaft screws as known withLOQTEQ small fragment plates

• In summary the aap implant system fulfills the mechanical requirements, because it matches the properties of current implant systems. The mechanical properties of the system by the competitor Synthes could be exceeded.
