The dangers of periosteal herniation include deformity of the foot, pain in the herniated area, and abnormal gait. Patients with herniated foot navicular bone should go to the hospital in time for early detection and early intervention and treatment in order to achieve better results. In the process of walking, the other parts of the foot are easily compressed, so the foot will be deformed due to the uneven force in the long term. The herniated navicular bone will constantly wear against the shoe, and the worn skin will break down, causing severe pain. A herniated navicular bone can destabilize the attachment point of the tendon next to it, weakening the tendon. As a result, there is an imbalance of strength between the inner and outer sides of the foot, resulting in a collapsed arch, pronation, or other conditions.
