What condition is characterized as stenosing tenosynovitis with pain over the radial styloid?

De Quervain's contracture, also known as De Quervain's tenosynovitis, is specifically characterized by stenosing tenosynovitis affecting the extensor pollicis brevis and abductor pollicis longus tendons. The hallmark symptoms include pain and swelling over the radial styloid, which is located at the base of the thumb. This condition is commonly associated with activities that involve repetitive wrist and thumb motions, leading to inflammation of the tendon sheaths in the wrist.

The pain typically worsens with movements that involve pinching or gripping. A positive Finkelstein's test, where the individual bends the thumb across the palm and then ulna deviates the wrist, can elicit the discomfort and provide diagnostic support.

In contrast, carpal tunnel syndrome involves the median nerve compression at the wrist, leading to symptoms such as numbness, tingling, and weakness in the thumb and fingers but does not primarily involve pain over the radial styloid. Trigger finger refers to a different issue involving the flexor tendons, leading to locking or catching of the finger rather than pain specifically over the radial styloid. Ganglion cysts are fluid-filled sacs on the wrist or hand that may cause discomfort but are
