Radial styloid process pain

Introduction In patients with sacral stem tenosynovitis, the fist scapular test (Fin kelstain sign) is often positive: the thumb is held in the palm of the hand, the fist is fisted, and the wrist is flexed to the ulnar side. At this time, there is severe pain in the styloid process of the humerus.

Cause

The stenosis of the stenosis of the sacral styloid tenosynovitis (Orthopedics) is due to the frequent movement of the thumb or wrist. The long extensor muscles of the thumb and the long abductor tendon of the thumb are repeatedly rubbed in the tendon sheath of the sacral styloid process, resulting in sterility of the tendon and tendon sheath. Inflammatory reaction, local exudation, edema and fibrosis, thickening of the sheath wall, local thickening of the tendon, causing clinical symptoms caused by the sliding of the tendon in the tendon sheath.

1. The sacral styloid process is uplifted and painful. It can radiate pain to the forearm and thumb. When the wrist and thumb are active, the pain is aggravated and the weight cannot be lifted.

2. The tibial styloid process is markedly tender, sometimes touching the hard nodules. The wrist and thumb activities are slightly limited.

3. The fist weight test (Finkelstein sign) is positive.

Differential diagnosis

Localized pain in the styloid process of the humerus: Tendonitis of the stenotic styloid process is mainly characterized by localized pain in the styloid process of the humerus. The onset of the disease is slow and gradually worsened. There is a pain in the bony process (stem of the humerus) and the thumb around the thumb. The thumb is blocked, and there is tenderness and friction in the styloid process of the humerus. Sometimes there is a styloid process in the humerus. Slightly uplifted pea-sized nodules. If the thumb is gripped in the other four fingers and the wrist is flexed to the inside of the wrist (the ulnar side), severe pain occurs at the styloid process of the humerus. In the acute phase, there may be local swelling. When the swollen tendon passes through the "tunnel" of the narrow tendon sheath, the sound of the thumb will occur when it is in the middle of the bend, which is also known as the "snap finger".

Wrist pain: Wrist pain caused by wrist injuries, arthritis, tendinitis and other diseases. Wrist sprains, 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.

Diagnose based on:

1. Pain when the wrist is forced or lifted.

2. The tenderness of the sacral styloid process can be touched by hard nodules.

3. Finkelstein sign positive.
