The fracture of the navicular bone of the right foot should be examined by X-ray or CT if necessary to clarify the specific characteristics of the fracture and then determine the treatment plan after the fracture. If the fracture is not large, there is no obvious misalignment, and the joint surface is not involved, the fracture can be treated conservatively by external fixation in a cast for about 1.5 months, and then a review of the fracture healing will be taken to determine whether the cast can be removed. However, if the fracture is significantly misaligned, resulting in significant misalignment of the joint surface adjacent to the navicular bone, surgical plate or screw fixation is needed to restore the original position of the fracture in order to avoid as much as possible the sequelae of pain or traumatic arthritis in the ankle area due to this type of fracture. In addition to the active treatment mentioned above, good joint function rehabilitation exercises are needed at a later stage to gradually return to the normal level.
