Abstract
We report on the first clinical cases of the Arthrex Ankle Syndesmosis TightRope (winner of 2003 BOA Technological Achievement Award and 2004 Cutlers' Prize), which has recently been licensed for use where classically a syndesmosis screw would be used.
Twelve patients with Weber C ankle fractures treated with Arthrex TightRope syndesmosis fixation have a minimum of six months follow-up. The syndesmosis was fixed with the ankle in plantarflexion to aid reduction. Patient demographics, including fracture classification and mode of injury were obtained. Parameters measured at follow-up included ankle range of motion, maintenance of reduction and fibular length, and AOFAS ankle outcome score.
The patient cohort showed a typical bimodal distribution of age. Age over 65 years was associated with a poorer outcome. Five patients had ankle fracture-dislocations, which was a factor for a poorer outcome. Nine patients had fibular plate fixation in addition to syndesmosis fixation, whilst three patients with Maisonneuve injuries had syndesmosis fixation only. There were no major complications, loss of reduction, wound problems, implant loosening or osteolysis. Ankle dorsiflexion was not restricted and mean total ankle range of motion was comparable to the uninjured side. No patient required secondary surgery for any reason, including hardware removal.
Arthrex TightRope fixation is a simple, safe and effective method of ankle syndesmosis fixation, which allows physiological micromotion. Fixation in plantarflexion provides optimum syndesmosis compression for reduction, and does not compromise ankle range of motion. The Arthrex Ankle Syndesmosis TightRope may become the treatment of choice in Weber C ankle fractures.
