Introduction: Talus fractures have traditionally been reported as having poor outcomes with rates of avascular necrosis in excess of 80% in some studies. It was noted by the senior author that this was not his experience in a tertiary institution with many patients having good to excellent outcomes and lower rates of avascular necrosis than anticipated despite high-energy trauma. The aim of this paper is to review all talus fractures that have been fixed internally at our institution to determine whether current surgical techniques have improved traditionally poor outcomes. This could result in improved outlook for patients on initial presentation and improved ability to manage the long-term consequences of the multiply-injured patient.

Method: A review of all lower limb trauma cases from 2012-2015 was made. This yielded 28 talus fractures that had been internally fixed at Southmead hospital. Patients were contacted using telephone and letters. The AAOS Foot and Ankle Outcome Questionnaire, patient satisfaction surveys and analysis of radiographs were made.

Results: Our preliminary results suggest avascular necrosis rates of less than 10% despite the high energy, sometimes open nature of these injuries. We also report that patients are returning to work and are reasonably satisfied following their injury. Fixation methods varied between cases but generally good outcomes were reported amongst most patients. We summarise the demographics of patients presenting with talus fractures and classify their initial injury according to the Hawkins talus fracture classification.

Conclusion: Our results were surprising. They suggest that modern surgical techniques may be improving outcomes for patients with talus fractures. It was previously thought that these injuries can be career-ending for some patients but we would suggest that there is hope for good outcomes in this patient group.
