Purpose
[edit | edit source]
To test the presence of either a bony fracture or for elbow joint effusion.[1] [2]
Technique
[edit | edit source]
The patient extends elbow as far as possible while either supine or in a standing position. The examiner will assess to whether the patient achieves full extension.
A positive test is if the patient is unable to fully extend the elbow.[3]
