Long muscle
The tendon and the 18 muscle in the hand are connected into a whole through ligaments, joints and skin. Some tendons of the hand are covered with a layer.
fibrous tissue
, named
tendon sheath
. It has the function of maintaining normal finger flexion and extension and tendon sliding. When the hand is fixed in a certain position for repeated and excessive activities, friction often occurs between tendon and tendon sheath, resulting in edema.
fibroid tumor
Changes, resulting in lumen stenosis. Because the tendon moves in the tendon sheath, it passes through a narrow path, causing pain and pain.
dyskinesia
Here it is.
peritendinitis
, again.
stenosing tenosynovitis
Known as.
Tenosynovitis is a common disease, which mainly occurs in the wrist.
radius
The common tendon sheath at the lower end of abductor pollicis longus and extensor pollicis brevis and the flexor pollicis longus tendon sheath at the first metacarpal are the two most common female workers in cigarette factories.
wrapping machine
, binding machine;
stapling machine
, calligrapher, housewife, painter, etc. There are two common tenosynovitis.
( 1)
Stenosing tenosynovitis of styloid process of radius
The onset is slow and gradually aggravated, and the thumb side of the wrist appears.
protuberance
Pain around the styloid process of radius and thumb, obstruction of thumb movement, tenderness and friction of styloid process of radius, and sometimes there are slight pea-sized nodules in styloid process of radius. If you hold your thumb tightly with your other hand
Four fingers
Inside, and bend the wrist to the inside of the wrist (ulnar side), then severe pain occurs at the styloid process of the radius. There may be swelling locally in the acute stage. When the swollen tendon passes through the narrow tendon sheath, the thumb will make a sound when it flexes.
snap the fingers
"I said.
(2)
Tenosynovitis of flexor tendon
Most of them happen in
Thumb and middle finger
. Finger flexion and extension dysfunction is particularly obvious when you wake up in the morning, and it can be alleviated or disappeared after the activity. Pain sometimes radiates to the wrist.
metacarpophalangeal joints
Flexion can be tender, and sometimes thickened tendon sheaths and pea-sized nodules can be touched. When bending the affected finger, it suddenly stays in the semi-bending position, and the finger can neither be straightened nor bent, as if it were suddenly "stuck", and the pain is unbearable, so it is necessary to use the other hand to help.
Pull
Later, the fingers can move again, producing the action and snapping sound like a gun wrench, so there is also "
Trigger finger
"or" snap your fingers "
The treatment methods of tenosynovitis are:
Reduce finger movements at an early stage and let local areas rest; Massage and acupuncture have certain curative effects; acetic acid
hydrocortisone
、
Triamcinolone acetonide acetate
Or injecting 0.25 ml prednisolone acetate into tendon sheath for local blocking, which has good curative effect; For the authors with a long course of disease and recurrent diseases, the narrow tendon sheath can be cut in parallel and partially removed, so that the tendon sheath will no longer squeeze the tendon, which can achieve the goal of radical cure.
