6Lag screw insertion

The area distal to the Blumensaat’s intercondylar roof line must be avoided

General consideration

In general, the screws are inserted at points along the midshaft axis of the femur (dotted line). The area distal to the Blumensaat’s intercondylar roof line must be avoided, in order not to violate the notch. In addition, the area of the medial knee recess should be avoided.

If you need to insert a screw in the area distal to the Blumensaat’s intercondylar roof line, direct the screw anteriorly, in order to avoid the intercondylar notch.
