A raised bone in the wrist is usually normal, but it can also be due to trauma, tendon sheath cysts, osteophytes or tumors. 1. Normal condition: The raised bone in the wrist of healthy people is called the radial tuberosity, which is more obvious in big-boned and thin people, and will not cause pain and other abnormal symptoms. 2. Trauma: impact, sprain, etc. may lead to displacement of the wrist bone, forming a bulge, accompanied by obvious pain, swelling, and difficulty in movement. 3. Tendon sheath cysts: soft tissue injuries caused by overwork or acute injuries to the wrist due to work, sports or games, etc. Continuous stimulation of inflammatory factors leads to calcification of soft tissue, forming a bump at the bone that is elastic and painful when pressed. 4. Osteomalacia: caused by joint degeneration, long-term wear and tear, metabolic abnormality, etc., manifested as bone bulge, pain, morning stiffness, and rattling sound when moving the joints. 5. Tumor: Bone tumor, chondrosarcoma, etc. will form bumps in the joints, which will continue to grow and cause pain, elevated skin temperature, impaired movement and pathological fracture, etc. If the wrist bone bumps show persistent pain, it will cause pain, stiffness in the morning and rattling in the joints. If the bump on the wrist bone is persistently painful or becomes bigger, it is recommended to consult a doctor as soon as possible.
