Ankle fractures are one of the most common bony injuries presenting to the trauma surgeon. The more severe ones result in disruption of the tibiofibular syndesmosis and hence worse outcome. The outcome depends on accurate reduction of syndesmosis. The two main options in managing these injuries are syndesmotic screws or tightrope. The aim of this study is to compare the rate of complications between these two techniques and their radiographic results.

Retrospective data from 62 patients between September 2009 and March 2011 who had fixation of syndesmosis was obtained from theatre logbooks. 46 patients had syndesmotic screws inserted while 16 had tightrope. The average age was comparable in both groups (51 years v/s 41). 25 of the 46 syndesmotic screws inserted were removed. No tightropes had to be removed for any reason. 2 patients with syndesmotic screws had wound complications while 1 patient which tightrope insertion had a persistent diastasis.

There were no differences in radiological outcome between the two groups with regards to reduction of syndesmosis (measured by talofibular clear space minus medial clear space) (p-value 0.283). The difference between the talocrural angles was also of no significance (p-value 0.344). Our results indicate that tightropes achieve radiologically similar reduction of syndesmosis as screws without any significant difference in complications. The need for a second operation is significantly lower with tightrope fixation.
