Ankle fractures account for 10% of all fractures. Most deformed looking ankles are manipulated in the emergency departments (ED) on clinical judgement in order to improve the outcome and avoid skin complications. It is accepted that significantly displaced ankle injuries with neurovascular (NV) compromise or critical skin should be reduced prior to imaging.

However, is it really possible to understand the injury to an ankle without an x-ray or other imaging? The other possible injuries around the ankle, presenting with swelling and deformity of the ankle region, may include a ligamentous, talar, subtalar, Chopart joint or calcaneal injury. Does the risk of waiting for the imaging outweigh the benefit of manipulation of an undiagnosed injury?

This prospective study involved the analysis of all patients with ankle injuries referred to orthopaedics between November 2009 and February 2010. Results: Over the audited period 100 referrals were identified (43 male, 57 female). The average age was 50.4 years (range 5–89). Only 2% of fractures were open. Manipulation in the ED was performed for 44% of patients. Of these, 39% (17 cases) were manipulated and supported in plaster slab without an initial x-ray; 3 due to vascular deficit, 2 due to critical skin and 12 with no documented reason!

Re-manipulation in the ED as well as definitive open reduction and internal fixation (ORIF) were significantly lower in those patients who had an x-ray prior to manipulation (p < 0.05). ORIF was performed in 68% of all patients. Importantly, 80% of ankles manipulated in ED went on to have ORIF which was significantly higher than the 47% in the non-manipulation cohort (p < 0.05).

We conclude that taking ankle injury radiographs prior to any attempt at manipulation, in the absence of NV deficit or critical skin, will constitute best practice.
