Protruding big toe joints of the foot can be treated in several ways: First, if the bunion is causing the big toe joint to protrude, conservative treatment or surgery should be performed. Mild cases can be treated with orthopedic bands worn 24 hours a day to correct the bunion. In the case of severe cases, surgical treatment is required to remove the hyperplastic bunion and the inflamed area of the bunion, as well as to cut off the bunion adductor muscle and, if necessary, to perform a wedge osteotomy. With the above treatment, the bunion can be corrected. Second, if the protrusion is caused by arthritis of the first metatarsophalangeal toe, serious cases need to consider artificial joint replacement surgery, which can completely solve the joint protrusion, and relieve joint pain and restore the range of motion of the joint, which is a better treatment method. Protrusion of the big toe joint of the foot should be diagnosed and treated promptly in order to enable the patient to fully recover from life and work.
