Introduction: Several methods for the management of syndesmosis disruption during ankle fracture fixation have been documented The Tightrope anchor is a relatively new technique consisting of two buttons and a strand of Fiber-wire which is looped twice though the buttons to create a pulley effect between the fibula and tibia, thereby stabilising the ankle syndesmosis. We have reviewed the outcomes in 38 patients treated with this technique.

Materials and Methods: Data including nature of operation, complications and the need for subsequent surgery were recorded for all patients receiving a Tightrope from May 2006 to September 2008.

Results: The mean patient age was 35 years, and 23 were male. 30/38 patients required no further surgery and had a good functional outcome. Two patients had prominent fibula plates removed but achieved good functional outcomes. For one patient a Tightrope was performed following diastasis screw failure: an improved but suboptimal outcome was achieved. A patient with fibromyalgia had a good range of movement but complained of discomfort. One patient with Poland sequence, who fell post operatively, needed tightrope removal and syndesmosis debridement resulting in a good but painful range of movement. Another patient developed a pulmonary embolus following surgery and prolonged swelling and discomfort limited her functional capacity. Two patients required tightrope removal and significant wound debridement following osteomyelitis of the fibula and tibia.

Discussion and Conclusion: The Tightrope is an effective method of ankle syndesmosis repair, with a reduced need for subsequent diastasis related surgery (35/38) when compared to our diastasis screw method (100%). However, our significant rate of osteomyelitis is disturbing, warranting further investigation.
