Most fractures of the little finger can be treated conservatively. As long as the fracture of the little finger is well aligned, there is no obvious deformity, or even if there is a slight angular deformity, after the fracture is healed, there is no obvious impact on the function, it can be treated conservatively. You can choose to use the plaster external fixation or a small splint specifically for the finger external fixation, and then bone grafting and calcium medication, during which close observation is needed to prevent the fracture end from displacement. If the fracture of the little finger has poor alignment and is expected to leave functional limitations after healing, or if the deformity is obvious, manipulation can be considered. If the fracture is still not in alignment and the fracture is not stabilized by manipulation, internal fixation of the fracture with incision and reduction may be considered.
