Radial styloid process stenosing tenosynovitis release

Tenosynovositis of the sacral styloid process is also known as tenosygic abdominis and stenotic tenosynovitis of the extensor pollicis. Because the thumb long extensor muscle and the short extensor muscle of the thumb originate from the dorsal medial aspect of the humerus and the interosseous membrane, together with the stenosis of the styloid process, they stop at the base of the first metacarpal and the base of the first phalanx. After excessive tension or repeated injury of the tendon in the tendon sheath of the humerus for a long time, the synovial membrane presents edema and exudation, which causes thickening, adhesion or stenosis of the tendon sheath wall, which is called stenotic tenosynovitis of the sacral styloid process. Treatment of diseases: tenosynovitis purulent tenosynovitis Indication After excessive tension or repeated injury of tendon in the tendon sheath of the humerus for a long time, the synovial membrane presents edema and exudation, which causes thickening, adhesion or stenosis of the tendon sheath wall. Contraindications Pay attention to aseptic operation during operation, reduce the chance of infection, and complete the release of the tendon block with as few cuts as possible, completely loosen the adhesion between the tendon and the tendon sheath without causing unnecessary damage to the tendon and its surrounding tissues. The secondary damage. Preoperative preparation It is used for a long course of disease, thick sheath wall, local elevation, or repeated treatment by conservative treatment (physical therapy, intrathecal injection of hydrocortisone acetate). Identify the tender nodules at the styloid process of the humerus, the inflamed tendon sheath. Surgical procedure 1. A longitudinal incision or a transverse incision can be made in the styloid process of the humerus. The former is easy to expose, but it is prone to long scars. The latter is not as good as the former, but it does not see scars after healing. Make a small curved incision, the subcutaneous tissue for blunt dissection, be careful not to damage the sacral nerve branch. 2, revealing the long abductor tendon and the buckling extensor tendon fibrous epithelial sheath. 3, cut and cut the fiber sheath, loosen the tendon, see the tendon is compressed, thin, whitish. 4, explore the local presence or absence of vagus tendon, if it should be removed. 5. Close the wound. The thumb can actively stretch and flex freely. complication The sacral nerve branch passes through the styloid process of the humerus and is located under the skin. Be careful not to damage it during surgery. Surgery must be explored, whether it is completely loosened, the vagus tendon fibers are separated, otherwise the symptoms can not be completely relieved after surgery.
