Whether the fracture of the base of the first metacarpal bone can be treated conservatively needs to be judged according to the degree of injury, if the degree of injury is mild, it can be treated conservatively, and if the degree of injury is severe, it needs to be treated surgically. If the fracture of the base of the first metacarpal bone does not involve the joint surface, the fracture is not very serious, the fracture is well aligned after manipulation, and it is not easy to be displaced after fixation, the fracture can be fixed with an external fixation cast or a brace. If the fracture of the base of the first metacarpal bone involves the articular surface, has a comminuted fracture, the fracture is not well aligned after manipulative repositioning, and is easily displaced after fixation, or if you are engaged in a job that requires high precision of the fingers, such as playing the piano, etc., you will need to be operated on and the fracture site will be effectively internally fixed. After the occurrence of the first metacarpal base fracture, it is recommended to consult a doctor in time and follow the doctor’s instructions to carry out standardized treatment, do not blindly and indiscriminately, so as to avoid delaying the condition.
