3Plate and screw characteristics

Types of cannulated screws

Screw types

There are five types of cannulated screws that can be inserted into the head of the Condylar LCP. Of these, 3 are different types of screws which fit into the central hole of the plate. These 3 screws are characterized by the type of head (threaded versus conical) and the length of thread (fully threaded versus partially threaded):

  1. The cannulated 7.3 mm locking screw creates a fixed angled construct.
  2. The cannulated 7.3 mm conical screw (fully threaded) compresses the plate to the lateral femoral condyle.
  3. The cannulated 7.3 mm conical screw (partially threaded) compresses the plate to the lateral femoral condyle and provides interfragmentary compression across the intercondylar split.

    There are two types of screws which fit the peripheral holes in the head of the Condylar LCP.

  4. The fourth type of screw is the cannulated fully threaded 5.0 mm locking screw which creates a fixed angle construct.
  5. The cannulated 5.0 mm partially threaded conical screw compresses the plate to the lateral femoral condyle and provides interfragmentary compression across the intercondylar split.
