Treatment for fractures of the digital metacarpal bone usually includes the following: 1. Conservative treatment is the application of plaster fixation, finger external fixator fixation or phalanx scaffold fixation for relatively stable phalanx metacarpal fracture. This treatment is suitable for patients with a stable fracture without significant displacement. 2. Surgical treatment is required for more serious fractures of the finger and metacarpal bone, such as obvious displacement of the broken end of the fracture, joint instability or joint dislocation. Surgical options include internal fixation, external fixation, and arthroscopic surgery, depending on the type and location of the fracture. 3. Rehabilitation treatment is after the fracture is cured, the patient needs rehabilitation treatment, such as finger joint activity exercise, physical therapy, functional exercise, etc., to restore the normal function and strength of the finger.
