Hammertoes can be recovered without surgery if the symptoms are mild, while more serious cases need surgery. 1. Non-surgical treatment: Hammer finger is caused by the rupture of the extensor tendon of the finger, resulting in the inability to straighten the end of the finger, which resembles the shape of a hammer, and the symptoms of hammer finger are mild. If the extensor tendon of the finger is not completely severed, and the torn tendon or fracture piece is able to maintain contact with the base of the finger bone, it can be gradually corrected with splints and returned to normal. 2. Surgery: If the extensor tendon of the finger is completely ruptured, resulting in the inability to straighten the finger at the end of the finger, surgical treatment must be used to connect the broken extensor tendon of the finger and then use splints to fix the treatment. Hammer finger patients are recommended to go to the hospital in a timely manner, improve the examination to clarify the cause of the disease, to give targeted treatment or treatment, under the guidance of the doctor for treatment, can be “early detection, early diagnosis, early treatment” to reduce the adverse effects of the disease.
