 – balanSys REV – Extension Gap First: 3in1

Fig. 27

Fig. 28

Fig. 29

Insert the Reference Plate (77.02.0031) in the slot of 
the black Assembly Device (79.02.0271). Insert the 
Test Stem Core straight (79.02.0668) or with offset 
(79.02.0669) into the hole. 

Remark

The orientation of the Test Stem Core is correct when 
it can no longer be rotated. The laser marking is orien-
tated towards the Reference Plate.

Position the Trial Tibial Plateau (79.02.0060 to 
79.02.0064) onto the Test Stem Core. 

Put the Offset Alignment Disk (79.02.0287) onto the 
Trial Tibial Plateau (put the open rectangle window 
over the anterior nose of the Trial Tibial Plateau).
