Severe foot and ankle injuries at trauma units: a relic of the past?

Introduction: In April 2012 National Trauma Networks were introduced in England to optimise the management of major trauma. All patients with an ISS of ≥ 16 should be transferred to the regional Major Trauma Centre (level 1). Our hypothesis was that severe foot and ankle injuries would no longer be managed in Trauma Units (level 2).

Methods: A retrospective analysis of the epidemiology of severe foot and ankle injuries was performed, analysing the Gloucestershire foot and ankle trauma database, from a Trauma Unit, for a catchment population of 750,000 people. The rate of open fractures, mangled feet and requirements for stabilisation with external fixation were reviewed before and after the introduction. This was compared to the foot and ankle injuries triaged to the regional Major Trauma Centre (MTC) using the TARN database information.

Results: The incidence of open foot and ankle injuries was 2.9 per 100,000 per year. There were 5.1% open injuries before the Network and 3.2% after. There was no statistically significant change in the application of external fixators. The frequency of mangled feet was 3.6% before and 6% after the Network commenced, showing no significant fall. Analysis of TARN data from the MTC demonstrated that only 18% of patients had an ISS ≥ 16. The majority of patients brought to the MTC with foot and ankle injuries were either polytrauma patients (43%) or required plastic surgery intervention for open fractures (69%). Only 4.5% of patients had isolated, closed foot and ankle injuries.

Conclusion: We found there to be no decrease in our numbers of mangled ankles, external fixations nor open fractures following the introduction of the Trauma Network. There is still a need for Foot & Ankle Surgeons at Trauma Units to manage complex foot and ankle injuries, because the majority have an ISS < 16.
