NANCY LOVERIDGE discusses one of emergency nurses’ most common presentations, the anatomy and pathology of lateral ankle sprains and use of non-steroidal anti-inflammatory drugs

Ankle sprains remain one of emergency departments’ most frequently presenting complaints. Lorimer et al (2002) state that one individual per 10,000 each day will invert and sprain their ankle. This is reflected in the profile of A&E attendances; Kennet et al (1996) identifies that one in twelve patients attend A&E with an injury to their ankle. As an emergency nurse practitioner (ENP) my remit is to assess, diagnose and treat minor injuries and conditions. This restricted focus to the patient profile an ENP treats, means that ankle injuries constitute a substantial section of my case mix. There is a requirement from the Clinical Negligence Scheme for Trusts (CNST) to develop clinical guidelines for the most frequent conditions or injuries seen; ankle sprains are therefore an obvious choice.
