One thing is how tenosynovitis

Each person has 28 bones in hand, 24 from the forearm to the long and 18 hand tendons of the small muscle, with ligament, joint and skin into a whole. Some tendon in the hand outside wrapped in a layer of fibrous tissue, known as the tendon sheath. It has to maintain the normal flexion and extension and finger tendon sliding function. When the hand fixed to a certain location for duplication, excessive activities, tendon and tendon sheath between the frequent friction, resulting in edema, fibrous change, caused intracavity narrow. The tendon sheath in the activities, the Trail Road through the narrow, which have pain and movement disorders, and this is tenosynovitis, also known as stenosing tenosynovitis. Tenosynovitis is a common disease in the wrist distal radius bone outreach extensor pollicis longus muscle thumb with the total short muscle tendon sheath, and the first metacarpal bone flexor pollicis longus tendon sheath two most common in the cigarette factory workers, Packers , binding workers; sewing workers,member of the family women, artists, etc.. Common tenosynovitis have the following two. (1) radial styloid process stenosing tenosynovitis this disease onset slow, gradually worsened and the thumb side of a wrist bone sudden (radial styloid process), and pain around the thumb, thumb hampered activities in the radial styloid process and a tenderness friction flu, and sometimes the radial styloid process in a slight uplift pea-sized nodules. If the thumb firmly in the four other means, and the inner wrist (ulnar) for the flexor carpi activities in the radial styloid process occurring at the severe pain. In the acute stage, localized swelling can. When the swelling of the tendon sheath through the narrow "tunnel", the thumb in, will happen beep, which called the "Snapping that," said. (2) Multi-flexor tendon tenosynovitis thumb and middle finger occurred. With that malfunction, particularly evident during the early morning wake up, activities can reduce or disappear. Wrist pain sometimes to the radiation. Metacarpophalangeal joint tenderness buckling can sometimes be touched thickening of the tendon sheath,pea-sized nodules. When bending with that, suddenly remain in the semi-bending of fingers can neither extension, nor buckling, like being suddenly "card" to live as pain is just unbearable, with the other hand to assist, the finger can, produce kind of like pull bolt action and snapping, this is a "trigger means" or "Snapping that," said. Tenosynovitis treatment are: Early reduce fingers activities to be partially closed; massage, acupuncture have some effect; hydrocortisone acetate test with the pine, acetate or acetate - triamcinolone acetonide discretion pine Lung 0.25 ml injection within the sheath closure , have better efficacy; on the longer course, repeated attack, the therapy invalid, could cut narrow part of tendon sheath, parallel partial excision, so that no longer squeeze tendon sheath, to achieve radical goals.
