Purpose:The purposes of the present study were to find the ideal insertion position syndesmosis screw and relation to the surrounding anatomical structures when indirectly inserting the screw anteriorly at a 30 angle at 3 cm proximal portion of the ankle joint.
Materials and Methods:We performed computed tomography from the axial view in 20 normal individuals at 3 cm proximal portion of the ankle joint and divided the lateral side of the fibula into 4 sections. We drew a line from the middle of each of these 4 sections to the posterolateral tibia at a 30 angle and determined the relationship between each of these lines and the surrounding anatomical structures and confirmed the site at which each of these 4 lines passed through the posterolateral tibia which divided into 3 sections and the site of the fibula at which each of these lines passed through the middle 1/3 portion of the tibia.
Results:The posterior 3/4 portion of the fibula that passed through the middle 1/3 portion of the posterolateral tibia in 18 cases. The portion did not approach the surrounding anatomical structures(Peroneal vessels and the muscular portion of FHL).
Conclusion:The ideal insertion position of syndesmosis screw at 3 cm proximal portion of the ankle joint at a 30 angle is the posterior 3/4 portion of the lateral side of the fibula, and injury to the surrounding anatomical structures could be avoided when the screw passes through the middle 1/3 portion of the posterolateral tibia.
