1 Principles topenlarge
The peroneal nerve runs around the fibular neck. So be careful with the reduction and clamp placement.
2 Fixation topenlarge
Lag screw application
Optimal fixation is achieved by lag screw fixation in a proximal–lateral to medial–distal direction. The medial cortex of the fibula may be engaged. Usually 3.5 mm cortical screws are used.

Alternative: lag screw in medullary canal
Alternatively, a lag screw may be inserted at a steeper angle, into the medullary canal of the fibula. 4.0 mm cancellous bone screws can be used.
Any injury to the posterolateral corner should be repaired very early in the healing process. Residual knee instability will be the result if the posterolateral corner is not dealt with definitively at an early stage.
Secondary reconstruction provides worse results than early posterolateral corner repair.
