Around 302,000 people with soft-tissue ankle injuries present to UK emergency departments every year (Ferran and Maffulli 2006). These patients are generally treated conservatively with analgesia, ice, compression and elevation, and rest. There is some discussion in the literature about whether or not people with these injuries should be treated with non-steroidal anti-inflammatory drugs (NSAIDs), with some authors claiming that the inflammatory response following injury is part of the healing process and should not be halted. This article examines the literature on the efficacy of administering NSAIDs as the first-line drug management for ankle sprain. It also considers cost of treatment, prescribing practice and contraindications of NSAIDs.
