How to insert the seating chisel

Seating chisel insertion

Insert the seating chisel through its guide into the distal femur. Use the slotted hammer to control the rotation of the seating chisel in the bone, so that the tongue of the guide lies in the anatomical long axis of the shaft.

An assistant may need to apply counter pressure on the medial side of the femur, especially if preliminary lag screw fixation of an intercondylar split has been performed.
