If the fracture is not displaced, it should be treated conservatively; if the fracture is displaced, it should be treated surgically. If the fracture is not displaced, or if the fracture is well aligned after manipulation, the fracture should be immobilized with a brace or plaster for 1 month, and then the plaster should be removed to perform functional exercises as appropriate. If the fracture has obvious displacement or combined with the damage of the deltoid cartilage complex, it is necessary to take surgical treatment of incision reduction and internal fixation, and repair of the deltoid cartilage complex, and it usually takes 2~3 months to recover completely after surgery. The left ulnar styloid should be treated conservatively or surgically according to the specific degree of injury.
