What is the SLAP test?

Published in Shoulder Injury 2 mins read

The SLAP test, more accurately referring to a SLAP tear, describes a specific shoulder injury rather than a diagnostic test itself. SLAP stands for Superior Labrum, Anterior to Posterior. It refers to a tear in the labrum, which is the ring of cartilage that surrounds the socket of your shoulder joint. This tear specifically occurs in the superior (top) portion of the labrum, extending from the front (anterior) to the back (posterior).

While there isn't one singular "SLAP test," there are several orthopedic tests, like the O'Brien test, that doctors use to help diagnose a suspected SLAP tear.

Understanding SLAP Tears:

Here's a breakdown:

  • Labrum: The labrum is a crucial part of the shoulder, providing stability and cushioning.
  • Superior Labrum: This is the top portion of the labrum, where SLAP tears typically occur.
  • Anterior to Posterior: This describes the direction of the tear, running from the front to the back of the top labrum.
  • SLAP Tear: This is a tear in the superior labrum, from anterior to posterior.

Diagnostic Tests, including the O'Brien Test:

While there is no single "SLAP test," the following information about the O'Brien test helps to understand how a SLAP tear may be diagnosed:

  • O'Brien Test: This is one of the physical tests used by doctors to help determine if a person has a SLAP tear. According to the provided reference, the O’Brien test can:
    • Help diagnose a tear in the top or superior part of your labrum.
    • Help rule out other issues such as:
      • Rotator cuff tear.

It is important to remember that physical tests like the O’Brien test may not be conclusive, and imaging tests like MRI scans might be needed to confirm a SLAP tear diagnosis.

In summary, while you may hear about the "SLAP test," it's actually the SLAP tear that is being discussed. This type of tear is diagnosed through a combination of physical examinations and imaging, with tests like the O’Brien test being used to help evaluate the shoulder and rule out other possible issues.
