The “press test” identifies tears in the Triangular Fibrocartilage Complex (TFCC), crucial for wrist stability and smooth rotation.
How to perform the press test
The patient sits or stands, keeping their elbow flexed at a 90-degree angle and forearm neutral.
They then bring their palms together in a “praying” position, pressing them and fingers firmly.
If this action causes pain on the ulnar side of the wrist (where TFCC is), it indicates a potential tear or degeneration, making the test positive.
The press test is simple and non-invasive, and it can be a useful initial assessment tool. However, it’s not definitive. If a TFCC tear is suspected based on this test or symptoms, further diagnostic methods, such as an MRI or arthroscopy, may be recommended to confirm the diagnosis and assess the extent of the injury.
