Crank test details.

• A. Pain only at rest
• B. No pain
• C. Increased range of motion with no pain
• D. Pain or clicking with compression and rotation

Answer: (D)

The Crank test is used to detect a tear of the glenoid labrum, particularly a SLAP lesion, by provoking the joint through a combination of axial load and rotation. In this test, you apply a compressive force along the humerus into the glenoid and then rotate the arm. If a labral tear is present, this compression with rotation often reproduces pain and can produce a painful click or grinding sensation as the labrum catches or frays on the humeral head. That is why pain or clicking with compression and rotation is the best indicator of a positive test. Pain only at rest, no pain, or an increased range of motion with no pain do not reflect the provocative mechanics of this test and thus are not consistent with a positive Crank test for labral pathology.
