Leg/Knee Case 8 Background

Proximal Fibula Fracture


Isolated proximal fibular fractures are uncommon and are most often associated with other injuries, such as tibia fractures, lateral collateral ligament (LCL) tears or medial ankle injuries (Maisonneuve fractures). The fibula is a non-weight bearing bone that has various neighboring soft tissue structures. In particular, the peroneal nerve wraps around the fibular neck, and the peroneus longus and brevis muscles originate at the proximal fibula. The fibular head serves as an attachment of the LCL and biceps femoris tendon.
