Wrist pain on the thumb side

Introduction The mother's wrist, also known in medicine as "shoulder stenosis tendon bursitis", is a clinically common pain on the thumb side of the wrist. The tendon is like a flies, and the contraction of the muscles affects the tendon and drives the movement of the fingers. If the two tendons move too frequently, or if they are used in excess of the force of the load or in the incorrect posture, the tendon will be injured, and the surrounding synovial sac will be inflamed, causing pain on the thumb side of the wrist. Wrist and thumb activities. Women are ten times more likely to be male.

Cause

There are two tendons at the base of our thumb, one is the thumb abductor long muscle, and the other is the thumb short muscle. When the thumb is raised, the two tendons can be touched at the base of the thumb. The tendon is like a flies, and the contraction of the muscles affects the tendon and drives the movement of the fingers. If the two tendons move too frequently, or if they are used in excess of the force of the load or in the incorrect posture, the tendon will be injured, and the surrounding synovial sac will be inflamed, causing pain on the thumb side of the wrist. Wrist and thumb activities.

Feniscos test

The position of the mother's wrist pain is where the thumb is near the wrist. Symptoms usually increase slowly, not suddenly. In severe cases, it will not only hinder the movement of the wrist, but also affect sleep. The patient will feel the joints stiff, and even like neuralgia, it will hurt to the arm and hurt to the big. The end of the thumb. Pain often worsens when the palm is gripped, the thumb is lifted, and the wrist is bent toward the little finger. It can be seen that there is a little edema at the styloid process at the end of the wrist and the pain at the time of compression.

Do the Fencos test, hold your thumb and bend your wrist to the side of the little finger. Because the inflamed tendon sac is pulled by the tension, it may be the mother's wrist.

Differential diagnosis

Wrist swelling and tenderness: The lower end of the humerus fracture is mainly characterized by swelling and tenderness of the wrist. Distal radial fractures are extremely common, accounting for about 1/10 of the usual fractures. More common in older women, children and youth. The fracture occurred in the range of 2 to 3 cm distal to the humerus. Often accompanied by damage to the wrist joint and the lower ankle joint.

Wrist pain: Wrist sprain, with a significant history of trauma. After the injury, the wrist is weak and the wrist is not active. Minor injuries, generally no obvious swelling, pain is not very good, only when there is a large movement of the wrist joints began to have pain. Severe sprains may cause swelling of the wrist, severe pain, and increased pain when the wrist or movement is not active. During the examination, the wrist joint is flexed and the pain is on the dorsal side, which indicates that the dorsal ligament of the wrist and the wrist extensor tendon are damaged; otherwise, the ligament of the wrist or the flexor tendon of the wrist is damaged. If the wrist joint is deflected to the ulnar side, and the pain occurs in the styloid process of the humerus, the collateral ligament injury is caused; otherwise, the ulnar collateral ligament is damaged. If there is pain in the movements of the wrist in all directions, and the activity is obviously limited, it means a composite injury of ligaments, tendons and the like. There is tenderness in the lesion or abnormal changes in the tissue of the tendon. Wrist injuries should be treated promptly to prevent ischemic necrosis of the wrist scaphoid and wrist and lunate bone.
