Bone Parallel To Fibula. The fibula is a bone in the leg located between the knee and ankle joints that runs in parallel to the larger tibia or shin bone. The fibula can be fractured near the knee mid shaft or at the ankle.

The classical appearance of a Segond fracture is that of a curvilinear or elliptic bone fragment projected parallel to the lateral aspect of the tibial plateau. Braking travel time is significantly increased until 6 weeks after initiation of weight bearing in both long bone and periarticular fractures of the lower extremity. The fibula can be fractured near the knee mid shaft or at the ankle.
Fractured malleoli The following x-ray shows a shortened fibula.
The joint gap between the lateral ankle and talus is no longer parallel. The peroneus longus tendon turns medially between the cuboid groove and the long plantar ligament and inserts onto the plantar surface of the base of the first metatarsal and the lateral aspect of the medial cuneiforms. This has been referred to as the lateral capsular sign 1 which is best seen on the anteroposterior view of the knee. Joint surfaces are parallel to each other.
