Isolated anterior syndesmosis diastasis without fracture.

Pure syndesmosis disruption at ankle without fracture of the fibula was rare. We reported a young man who had persistent left ankle pain and swelling 4 weeks after road traffic accident. X-rays did not reveal any fracture along whole fibula. Computed tomography showed anteriorly displaced fibula at syndesmosis level. Arthroscopic reduction and syndesmosis screw fixation followed by ligament reconstruction was done. Finally, he enjoyed pain-free range of motion of his ankle.
