There is an ongoing discussion on how to best
stabilize syndesmotic injuries. Previous studies have indicated a
better quality of reduction of the distal tibiofibular joint (DTFJ)
for the suture button systems compared to syndesmotic screw
fixation. Still, the reason for this superiority remains unclear.
The aims of this retrospective study were to (1) analyze the
deviation of the tibial and fibular drilling tunnels of the suture
button system and (2) to compare these to the quality of reduction
of the DTFJ assessed on bilateral postoperative CT images.
In conclusion, a suture button system
postoperatively deviates and apparently has the capacity to
compensate for intraoperative malreduction. Analysis of the
drilling tunnels revealed that the use of a rigid fixation system
would have doubled the postoperative malreduction rate.
