There are two thumb tendons, the Abductor Pollicis Longus (APL) and the Extensor Pollicis Brevis (EPB), that are involved in the onset of the condition known as ‘De Quervain's Tenosynovitis.’ Travelling side by side along the inside of the wrist they pass through a Synovial tunnel on the thumb side which helps to keep them in place. They glide back and forth freely to move the thumb because of a slippery coating called ‘Tenosynovium’ and when this and/or the tendon become inflamed it results in Tenosynovitis and when that inflammation restricts the movement of the tendons in the tunnel, the diagnosis is ‘De Quervain's Tenosynovitis.’

How do I know I have De Quervain's Tenosynovitis?
You may well have De Quervain's Tenosynovitis if you experience any of these symptoms:
What is my best course of action?
It is best to see your physiotherapist as soon as possible and you can save time and money by going directly to them. No extensive testing is required to accurately diagnose De Quervain's Tenosynovitis. A test known as The ‘Finklestien test’ is usually used and is one of the best. You will be advised on what hand and wrist movements to rest and restrict or possibly to wear a ‘thumb-spica’ splint which stops the wrist and lower joints of the thumb moving, thereby allowing the APL and EPB tendons a chance to rest. Contact us for an accurate diagnosis and treatment that will get you back to normal as soon as possible.
