According to the preliminary diagnosis, many phalangeal fractures of the foot are partial nonunion after manual reduction, which is generally caused by poor reduction or serious injury and slow healing. As long as the guidance is well aligned and there is no obvious displacement, it can generally be treated conservatively. Continue to raise the affected limb, apply local hot compress, and start slow rehabilitation exercise. As long as there is no obvious pain and discomfort, you can keep exercising. If you are in poor posture or have obvious pain, you usually need to see a doctor to see if you need surgery.
