BACKGROUND: Sprained ankles are common, and when there are no signs or evidence of a fracture conventional management is conservative. At present, there are no clinical markers to identify those that may develop persisting instability and disability that would require rehabilitation or surgery.
OBJECTIVE: To investigate the nature and extent of soft tissue ankle injuries, and to consider whether the anatomical severity of injury can predict functional outcome.
METHODS: Patients attending a local A&E department in Oxford with an acute ankle injury with no clinical requirement for radiographs, or where radiographs were normal, were invited into the study. Within 5 days patients underwent a diagnostic ultrasound examination, a cone beam CT study and a disability assessment. Ultrasound and physiotherapy assessments were repeated at 3 and 6 months.
RESULTS: 100 patients were recruited, and grouped based upon injuries. 58 had simple ankle injuries, 21 complex, 19 had significant fractures and 2 were excluded from further follow up analysis. There were no clinically significant differences in pain, disability or functional outcomes between the groups at all points of the study.
CONCLUSION: Medium to long term clinical outcomes were not solely determined by the severity of injury. Some patients with simple injuries were seen to have ongoing problems, whereas some with complex injuries recovered completely in a shorter period. Advances in Knowledge: The severity of an ankle injury determined by radiological imaging does not necessarily dictate the severity of a patient's symptoms and the trajectory of their recovery.
