De Quervain’s Syndrome

De Quervain’s Syndrome


What is De Quervain’s Syndrome, how can it develop, and what are the symptoms?



De Quervain’s Syndrome is a condition associated with irritation of the tendon sheaths, mainly the abductor pollicis longus & the extensor pollicis brevis, leading to radial side (outside) of the thumb. These sheaths become aggravated due to repeated movements of wrist rotation, grasping objects, or making a fist. This condition can also be seen if there has been a direct trauma to the area that the tendons cover creating adhesions, thickening, swelling, or scar tissue around the thumb and wrist.


Sports that commonly see this condition include golf, tennis, and badminton. The symptoms that are most commonly observed include pain/swelling near the base of your thumb and difficulty grasping objects.


A quick way to test yourself if you’re concerned about having this condition can be done using the Finkelstein Test.

To do this test on yourself:

  1. Hold your affected limb in a neutral position (thumb facing up)
  2. Simply tuck your thumb into your hand while making a fist & place your wrist into ulnar deviation (pinky towards the floor).

If you experience pain in the area around the base of the thumb, you may have this condition.
