Minor fractures of the finger usually require prompt external fixation after the fracture, either by splinting the hand or by using an aluminum plate to fix the finger in a straightened position. The duration of immobilization is about 3-4 weeks, so that when the fracture is removed after it has healed, the fracture can be kept in a good position without dislocation. If swelling occurs in the early stage of the fracture, you can take horse chestnut seed extract orally. If the swelling is relatively mild, you only need to take Chinese medicine to activate blood circulation and relieve pain and swelling, but if the pain is severe, you need to take diclofenac sodium extended-release capsule orally. This can effectively relieve the local pain, and as the symptoms continue to relieve the pain, you can move your finger under the protection of external fixation, and after the fixation is released, you can flex and extend your finger under the premise of very light, so as to accelerate the healing of the fracture.
