Stenosing tenosynovitis may present with clinical manifestations such as pain in the radial side of the wrist, limitation of activity, and interphalangeal joint deformity. 1. Wrist radial pain: it may be manifested as gradual aggravation of pain on the radial side of the wrist joint, which is closely related to the finger activities, and inability to lift objects, and there is no inflammation in the skin during the examination, but there may be limited pressure pain on the surface of radial styloid, and sometimes a painful nodule may be palpable. 2. Restriction of activity: it can be manifested as limitation of voluntary flexion and extension activities, pain in the fingers when flexing and extending with force, and bouncing movements, such as trigger-like, accompanied by popping sound. In serious cases, tendon entrapment may occur, and the affected finger cannot be straightened by itself. Symptoms may be aggravated after waking up in the morning and after labor, and will be reduced after activities or hot compresses. 3. Interphalangeal joint deformity: mostly due to congenital deformity, the little finger is more common, followed by flexion contracture of the interphalangeal joint of the middle finger, if found in the thumb, the deformity is located in the metacarpophalangeal joint.
