Clinical Prediction Rule of Haworth et al for a Displaced Zygomatico-Maxillary Fracture

Description

Haworth et al reported a clinical prediction rule which can help to identify a patient with a displaced zygomatico-maxillary fracture. This can help guide imaging studies. The authors are from University of Bristol, University Hospitals of Leicester and Glouchestershire Hospitals NHS Trust.


Observations:

(1) palpable bony step

(2) lateral sub-conjunctival hemorrhage with no posterior limit

(3) anesthesia or paresthesia to lip, cheek or side of nose

(4) palpable emphysema

 

The presence of one or more observations was associated with a displaced zygomatico-maxillary fracture.

 

An additional finding associated with fracture was bony asymmetry.

 

Performance:

• The sensitivity was 100% with a specificity of 73%.

• The negative predictive value was 100%.
