Tenosynovitis can be divided into several types: finger flexor tendon tenosynovitis, radial styloid stenosing tenosynovitis, and biceps long head tenosynovitis.

Finger flexor tendon tenosynovitis is also called trigger finger or snapping finger. It is more common in women and manual laborers. It can occur in any finger, but is more common in the thumb, middle finger, and ring finger. The lesion involves the finger joints, and in severe cases the joints cannot be straightened or flexed.

Radial styloid stenosing tenosynovitis is closely related to thumb movement. It is more common in women over 40 years old. Breastfeeding women may also suffer from this disease. The ratio of women to men suffering from this disease is about 6:1, and the lesions involve the wrist joints.

Tenosynovitis of the long head of the biceps brachii is common in people over 40 years old. It is more common in people who have shoulder trauma, excessive activity or are susceptible to cold. Its symptoms mainly include shoulder pain and limited joint movement.
