Fractures and Dislocations of the Proximal Fibula
- Lateral Collateral Ligament
- Maisonneuve Fracture
- occur most often in association w/ proximal tibial fractures, esp w/ split compression, bicondylar, and subcondlylar fractures;
- look for injury to peroneal nerve, anterior tibial artery, biceps tendon, & lateral collateral ligament;
- mech is usually a varus force;
- Avulsion Off the Fibular Styloid:
- exception is an avulsion of the fibular styloid with its attached biceps tendon and fibular collateral ligament;
- after fibular avulsion, it is important to test for peroneal nerve function &, if deficit is identified, nerve should be explored;
- knee instability is another reason to fixed theses fractures;
- Dislocation of the Head of the Fibula:
- initially attempt treatment w/ closed reduction and casting in extension;
- Anterolateral dislocation of the head of the fibula in sports.
- Isolated anterior dislocation of the proximal tibiofibular joint.
