Left radial tuberosity fractures often occur in clinical practice, and the only way to recover as soon as possible after a left radial tuberosity fracture is with proper treatment. If a linear fracture of the small head of the left radius occurs without displacement of the fracture end, conservative treatment is an option in treatment. A topical plaster can be applied to activate blood circulation and remove blood stasis, followed by external fixation with a brace or plaster rest. If the fracture of the left radial tuberosity is separated and displaced by muscle pulling, the treatment can be surgical, with incision and internal fixation such as hollow nail or Kirschner pin. After the fracture of the left radial tuberosity, the patient should consult the orthopedic surgeon and take the appropriate symptomatic treatment after a clear diagnosis in order to recover from the fracture as soon as possible.
