Technique Guide
Screw placement depends on the type of fracture. The
position of the screws should be chosen in accordance with
established biomechanical principles for internal fixation. The
screws should be inserted close to and remote from the
fracture gap in the main fragments. Use at least four screws
per fracture side.
Once the initial screw has been inserted in each main
fragment, length and rotation are defined. Ante- and
recurvatum deformities can still be manipulated relatively
well, whereas there are only limited correction possibilities
for varus/valgus deformities. Therefore, it is recommended to
insert the first screw in the distal fragment. The distal screws
should be placed parallel to the knee joint. 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.
