Conditions

Radial styloid tenosynovitis is a condition which the extensor pollicis brevis and abductor pollicis longus in the first extensor compartment are entrapped, causing severe pain at radial styloid, swelling, and crepitus in some patients. Women, who age fouth to fifth decade are at more risk to develop this disease. Many cases of tenosynovitis respond favorably to non-operative management such as rest, splinting, anti-inflammatory medication, and steroid injection. Steroid injection may complete
