It is a stenosing tenovaginitis of the tendons in thumb.
Sex- Women are more prone to this disease compared to men.
Age- Mostly found between ages of 30 & 50 years but anyone at any age can get it.
Aetiology-Exact cause is not known. It may be due to repeated overuse of the wrist. A direct blow to the thumb, & certain inflammatory conditions can trigger the disease.
Associated medical conditions- Pregnancy, diabetes mellitus, osteoarthritis, or rheumatoid arthritis.
Pathophysiology-There is apparently spontaneous thickening of the common sheath of abductor pollicis longus, extensor pollicis brevis tendons at the wrist & the consequent result is the entrapment of the tendon. The swollen tendons & their coverings rub against the narrow tunnel through which they pass. The result is pain at base of the thumb.
Clinical features- Presentation may be gradual or sudden. Pain along back of the thumb is the most common symptom. Thumb motion may be difficult & painful, particularly when grasping objects. There may be tenderness & swelling over the thumb side of wrist. Pain may be raised with movements of the thumb & wrist. Tenderness can be elicited by sudden ulnar deviation of the flexed hand. It is the surest sign for diagnosis of Dequervain’s disease & is known as Finkelstein’s test.
Investigations- No X-rays or laboratory investigations are usually needed for its diagnosis. But blood sugar examination to rule out diabetes mellitus & other investigations to see the presence of associated medical conditions like rheumatoid arthritis etc or any other pathology causing the symptoms are to be done.
Differential Diagnosis- Dequervain’s disease is to be differentiated from osteoarthritis of 1st carpo-metacarpal joint, Carpal Tunnel Syndrome, Intersection Syndrome etc.

Prevention- Prevention consists of avoidance of excessive movements such as hand & wrist twisting, pinching & forceful gripping.
Prognosis- Majority respond well with treatment if started early.
