How is periarthritis of the shoulder treated with block therapy?

The closed treatment for periarthritis of the shoulder is a method that involves directly injecting medication into the shoulder to relieve pain and inflammation. This treatment mainly includes the following aspects: 1. Local injection (block injection): A mixture of local anesthetics and steroid medications—such as lidocaine and triamcinolone acetonide—is injected into the painful area of the shoulder to reduce inflammation and pain. This method is commonly used to alleviate pain caused by acute or chronic soft tissue injuries in local muscles, tendons, and surrounding structures. 2. Intra-articular injection: For periarthritis caused by conditions such as arthritis, medications like sodium hyaluronate and bupivacaine can be directly injected into the joint cavity to reduce intra-articular inflammatory responses. 3. Precautions: Closed treatment must be performed under strict aseptic conditions. Shoulder movement should be restricted after injection, and overuse should be avoided. Additionally, patients should adjust their diet and avoid spicy and irritating foods. Closed treatment can effectively relieve pain and inflammation in patients with shoulder periarthritis, but it should be performed under the guidance of a qualified physician, with regular evaluation of therapeutic effects and potential side effects.
