Evolution of Syndesmosis Fixation

Syndesmosis fixation can be performed for those injuries indicated to undergo operative intervention. There are multiple methods of syndesmotic fixation to include both screw fixation as well as fixation with a suture button or tension wire construct. At this time there is no definitive evidence that either method is superior to the other. When screw fixation is utilized, a 3.5-4.5mm screw is placed across the tibio-fibular joint, essentially reinforcing their syndesmosis.

Typically, 2 screws are utilized, and they placed through both bones of the lower leg. An alternative is suture button or tension wire technology which accomplishes the same goal of re-enforcing the syndesmosis. In this technique, instead of utilizing screws, the surgeon uses a high-tension wire which spans the joint and is fixed to the bone on either side with a small button or some other method of fixation.
