What is thumb tenosynovitis?
Thumb tenosynovitis refers to thumb long flexor tenosynovitis of the first metacarpal head and flexor tendon tenosynovitis of the 2nd, 3rd, 4th, and 5th metacarpal bones. The tendons of the thumb long flexor muscle enter the neck of the first metacarpal bone into a narrow duct consisting of a bone groove and sheathed ligaments on the metacarpal side of the metacarpal bone. The seed bone at the base of the first phalange and its ulnar side are attached to the shallow and deep heads of the thumb brachysus flexor muscle, respectively, and the thumb long flexor tendon passes between the two. Chronic inflammation can occur when two tendons rub against the tendon sheath for a long time.
Manifestations of the symptoms of tenosynovitis
Tendon sheathitis of the flexor fingers occurs most often in the thumb and middle finger. It is particularly pronounced when waking up in the morning and can be reduced or disappeared after activity. The pain sometimes radiates to the wrist. Metacarpophalangeal flexion may be tender, sometimes touching thickened tendon sheaths and pea-sized nodules. When bending the affected finger, suddenly stay in the semi-curved position, the finger can not be straightened, but also can not be bent, like being suddenly "stuck", the pain is unbearable, with the other hand to assist the pull, the finger can move, resulting in a trigger-like action and pop, so it is also known as the "trigger finger".
Cause of tenosynovitis
It can be caused by injuries, excessive strain (especially on the hands and fingers), osteoarthritis, some immune diseases, and even infections. Occupations that require long-term repetitive straining of joints, such as typists, instrumental musicians, cargo handlers, or industries that require long periods of computer operation, can cause or worsen the disease. Common affected areas include wrists, fingers, shoulders, etc. Women and people with diabetes are more susceptible to the disease.

The affected joints are swollen, even bouncing, and joint mobility is obstructed.
