    Abstract

    Elbow injuries are commonly seen in accident departments. Patients with possible bony injuries to the elbow were assessed to see if inability to fully extend the elbow was a good indicator of bony injury and hence the need for X-ray. The sensitivity of this test was 90.7% (95% confidence limits 80.7-100.7) and the specificity 69.5% (95% confidence limits 60.3-78.7). Use of this simple test would reduce both radiography costs and unnecessary exposure to radiation.
