OA Hip VS Labaral Tear

Hi, may i know what objective tests can be done to confirm an OA hip and differentiate it from labrum tear.

Thanks!

It's a good question. Before sharing about the objective tests, let's discuss and understand more about OA hip and labrum tear.

The socket of your hip joint (acetabulum) is lined by cartilage called your labrum. This cartilage provides stability and cushioning for your hip joint, allowing the ball of your thighbone (femur) to move smoothly and painlessly in the socket.

A tear in your labrum, known as a hip labral tear or acetabular labral tear, can result from injury, repetitive movements that cause wear-and-tear on your hip joint, or degeneration, such as from osteoarthritis.

On the other hand, would a labrum tear resulted from a injury and repetitive movement result to earlier onset of osteoarthritis?????

So it is a good question whether is the presentation OA hip or Labrum Tear?

In the earlier discussion, the pathophysiological mechanism is different for the two conditions which means that you will need to obtain relevant information from the subjective examination e.g age, lifestyle, current history, etc.

Following that you would have established your provisional diagnosis (if OA, it would be confirmed via x-ray finding on the degenerative changes)

For OA hip: the articular system to test will be noted that the range will be limited whether AROM, PROM, accessory glide (stiffness)

For labral tear, confirming special test will be :
1) McCarthy
2) FABER
3) Impingement

Catching, locking, reproduction of symptoms are positive signs of labral tear.

Hope this helps.
