Isolated Fracture of the Posterior Margin of the Tibia: The Report of Three Cases in Our Milieu

The isolated fracture of the posterior margin of the tibia is a rare lesion. Painful swelling at the back of the internal malleolus area remains the main clinical sign. The common experience proves that the fractures of the posterior malleolus occupy a significant proportion of the fractures of the bones of the ankle, isolated fractures of the posterior malleolus, nowadays called fractures of the posterior margin of the tibia are relatively rare. An X-ray of the ankle is sufficient to confirm the diagnosis. Sometimes CT scan is used when there is a doubt or for old lesions. The management of ankle fractures, which is associated with posterior malleolus fractures, still has no consensus on the classification of the fracture, indications of surgery, operation technique and the best treatment algorithm, including functional outcomes. We report three cases of isolated fractures of the posterior margin of the tibia in young patients treated with a plaster cast boot in order to share our experience in management of such lesions.
