De Quervain's Tenosynovitis

De Quervain's Tenosynovitis
✅In this condition, inflammation involves the abductor pollicis longus and the extensor pollicis brevis as these tendons pass through a fibrous sheath at the radial styloid process.
✅The usual cause is repetitive twisting of the wrist. It may occur in pregnancy, and it also occurs in mothers who hold their babies with the thumb outstretched.
✅Patients experience pain on grasping with their thumb, such as with pinching. Swelling and tenderness are often present over the radial styloid process.
✅The Finkelstein sign is positive, which is elicited by having the patient place the thumb in the palm and close the fingers over it.
✅The wrist is then ulnarly deviated, resulting in pain over the involved tendon sheath in the area of the radial styloid. ✅Treatment consists initially of splinting the wrist and an NSAID.
✅When severe or refractory to conservative treatment, glucocorticoid injections can be very effective.
