Fractures of the lateral margin of the distal tibia are usually avulsion fractures of the anterior or posterior tibial tubercle, caused when the anterior or posterior inferior tibiofibular ligament fails to tear during an injury. Since they are generally the result of external rotation and abduction, they are almost always seen in association with other fractures and ligamentous injuries at the ankle joint. While their presence usually does not change the therapeutic approach, occasionally a large fragment may require a separate fixation screw. Fractures of the posterior tibial tubercle should not be confused with fractures of the posterior articular margin (posterior malleolus), which have a worse prognosis.
胫骨远端外侧缘骨折通常是胫前或胫后结节的撕脱骨折，由胫腓下前韧带或胫腓下后韧带在损伤时未撕裂所致。由于它们通常是外旋和外展的结果，几乎总是与踝关节的其他骨折和韧带损伤同时出现。虽然它们的存在通常不会改变治疗方法，但偶尔较大的骨折块可能需要单独使用固定螺钉。胫后结节骨折不应与预后较差的后关节缘（后踝）骨折相混淆。
