Finger joint capsule injuries need to be treated depending on the cause of their appearance. Treatment mainly includes: non-surgical treatment and surgical treatment. 1. Non-surgical treatment: it is suitable for patients with long-term chronic injuries or those with less serious joint capsule injuries due to trauma. The main modalities include braking of the affected limb, ice application, physical therapy, rehabilitation training and so on. If the pain is obvious, non-steroidal anti-inflammatory drugs such as ibuprofen and diclofenac sodium can be chosen to relieve the pain. 2. Surgical treatment: It is suitable for patients with joint capsule injury combined with joint dislocation, open injury or ligament rupture due to trauma. For patients with open injuries, debridement and exploration are required, and the joint capsule may have to be sutured if necessary. The main principle of surgery is to maximize the preservation of the original physiological anatomy as well as postoperative hand function. All of the above drugs should be used under the guidance of a doctor, avoid self-medication.
