Shetty test in ankle and foot trauma: An emergency department pilot study assessing specificity and sensitivity

Emerg Med Australas. 2020 Aug;32(4):683-686. doi: 10.1111/1742-6723.13541. Epub 2020 May 27.


Objective: To assess the potential impact of the Shetty test over Ottawa ankle foot rules (OAFR) on plain imaging utilisation in the ED.

Methods: Nursing and medical staff assessed both Shetty test and OAFR in ED. All patients received ankle and foot radiographs.

Results: Fifty-four participants were assessed. Shetty test specificity at triage was 0.40 (95% CI 0.25-0.57), compared to OAFR 0.10 (95% CI 0.03-0.24), McNemar's P < 0.01. Shetty test and OAFR sensitivity at triage was 0.92 (95% CI 0.64-0.99), McNemar's P = 1.00.

Conclusion: Shetty test may safely reduce unneeded radiographs in ED. Further research is warranted.
