DeQuervain's Syndrome

'What is the DeQuervain's Syndrome (Tendonitis and Tenosynovitis)?'

DeQuervain's Syndrome, also known as "washerwoman's tendonitis" is a painful swelling of the tendons or tendon sheaths at the base of the thumb.

'What are the common DeQuervain's Syndrome (Tendonitis and Tenosynovitis) symptoms?'

DeQuervain's Syndrome symptoms include pain and/or numbness at the thumb, especially the back of the thumb, as well as weakness ingripping.

DeQuervain's Syndrome can be diagnosed using Finkelstein's Test.

'What causes DeQuervain's Syndromes(Tendonitis and Tenosynovitis)?'

DeQuervain's Syndromes are most often caused by repetive thumb motions or by awkward use of thumb muscles/tendons. Most thumbs and hands are not prepared for this activity (thumb flexor muscles dominate extensors, causing imbalance). Because most folks do not exercise their thumbs and hands in preparation for repetitive activities, recent computer, gaming and PDA related conditions are making headlines (see 'Blackberry Thumb?' in Research).

Muscle imbalance is also a precurser for repetitive stress/strain injuries like carpal tunnel syndrome, tennis elbow and golfer's elbow.
