![]() ![]() ![]() The common peroneal nerve liesĬlose to the proximal fibula, where it divides into superficial and deep branches. Peroneal nerves, which innervate the lower leg. The fossa is also home to the tibial and common The popliteal fossa behind the knee holds ItsĮlevated position, as well as its relative weakness make it more prone to (Modified and annotated from - /media/File:811_Tibia_and_fibula.jpg )īears 60% of the joint load across the knee. The ligaments holding the tibia and fibula together are shown in green. LTP = lateral tibial plateau MTP = medial tibial plateau TT = tibial tubercle TS = tibial shaft Plaf= tibial plafond MM = medial malleolus LM = lateral malleolus FS = fibular shaft FN = fibular neck. Joint, which allows for dorsiflexion and plantarflexion of the ankle.įigure 1: Bony Anatomy of the Tibia and Fibula. Distally, the tibia and fibula articulate with the talus at the ankle Proximally, the tibia articulates with theįemur at the knee joint, which allows for flexion and extension of the lower The tibia is larger and located more medially and anteriorly theįibula is smaller, lateral, and posterior (Figure 1). The tibia and fibula are the two bones of That is because the fibula supports only approximately 10% of the bodyweight and the tibial shaft can adapt to greater loads if needed. Fibular fractures are problematic usually only to theĮxtent they involve the knee or ankle joints, or a fracture fragment injures Must be treated to restore rotation function, specific treatment of the fibular Unlike theĬase of a “both bones” fracture of the forearm, where both the radius and ulna The injury pattern is commonly called a “tib-fib” fracture. Much smaller lower leg bone, the fibula, is usually fractured when the tibia isīroken. Of those joints helps avoid the stiffness that cast immobilization might otherwise Joints surgical treatment thereby liberates the knee and ankle. Non-operatively requires a long-leg cast, one that crosses the knee and ankle Tibial fractures are best managed with surgical fixation. Plafond fractures are also peri-articular injuries, and they too can be complicated by post-traumatic arthritis. They are also associated with compartment syndrome. Shaft fractures are associated with acuteĬompartment syndrome and, owing to their subcutaneous location, have greaterĭifficulty healing. Thus may lead to post-traumatic arthritis. Tibial plateau fractures are peri-articular In each region have their own distinct concerns. Tibial plateau, near the knee the shaft and tibial plafond, near the ankle. Tibia, the larger of the two lower leg bones, can be broken in three areas: the ![]()
