In clinical practice, the common causes of a raised hard bag in the wrist joint are tendon sheath cyst, joint dislocation, fracture displacement, gout stone, scar hyperplasia, traumatic hematoma, etc., which need to be treated according to different causes. 1, tendon sheath cyst: Most of them are caused by long-term strain on the wrist joint, and the fluid in the tendon sheath will accumulate when the tendon sheath is injured and form a cyst that can be manifested as a raised hard bag in the wrist joint. The cyst can be manifested as a raised hard bag in the wrist joint, which can appear as local pain and swelling. Mild cases can be local heat, baking electricity, etc., but also joint puncture fluid treatment, if the conservative treatment is not effective, you can remove the cyst through surgery; 2, joint dislocation: wrist suffered trauma caused by small joint ligament tear, resulting in small joint dislocation, can cause the wrist joint has a raised hard bag. Patients with local pain and swelling, activity restrictions, this can be surgical treatment, perform incision and ligament repair suture surgery, in the post-operative need to use a cast or brace for external fixation; 3, fracture displacement: wrist trauma caused by fracture, fracture end displacement, will also lead to a raised wrist joint hard bag, treatment requires incision fracture repositioning internal fixation surgery, and in the post-operative oral to promote fracture healing drugs 4. Gout stone: If the long-term consumption of high purine food leads to gout attack, uric acid crystals are deposited in the wrist to form gout stone, resulting in a raised hard bag in the wrist joint. Such patients can be treated with medications such as indomethacin tablets, colchicine tablets, etc. Surgery can also be taken, such as gout stone removal surgery under anesthesia; 5, scar hyperplasia: common in the recovery process of trauma or surgery, if the patient has scar body, the formation of local scar hyperplasia, will also lead to a raised hard bag in the wrist joint, which generally does not require special treatment. If it affects the aesthetics, you can consider removing the scar and cooperate with radiotherapy, etc.; 6. Traumatic hematoma: If the wrist joint suffers from trauma, the capillary rupture forms a hematoma, which may lead to a raised hard bag in the wrist joint if left untreated for a long time, treatment can be performed by puncture and fluid extraction to draw out the accumulated blood from the injured area, and pressure bandaging.
