 Rent Test | Transdeltoid Palpation

What is the Rent Test?

The Rent Test (or Transdeltoid Palpation test) is used to diagnosis the full thickness tear of the shoulder rotator cuff.

How do you perform the Rent Test?

Rent Test

What does a positive Rent Test mean?

In the presence of a complete rotator cuff tear, the eminence of the greater tuberosity appears quite prominent to palpation, and the torn area feels like a sulcus “rent”, or soft-tissue defect (depression of approximately 1 finger-width) that has avulsed from the tuberosity.

Palpating the anterior and posterior margins of the cuff tear may elicit an avulsed edge.

It is recommended that this test be used to determine the absence or presence of a rotator cuff tear rather than the size of the tear.

Sensitivity & Specificity

One study by Wolf 1 to assess the diagnostic accuracy of transdeltoid palpation (the rent test) for the diagnosis of full thickness rotator cuff tear, Transdeltoid palpation was found to have a:

rortator cuff full thickness tear vs partial tear
Rortator cuff full thickness tear VS partial tear
