The visible fracture line of the external ankle joint at 2 months means that the broken end of the fracture has not yet healed, which may be related to the slow formation of bone scab. Fractures of the ankle joint or other parts of the general in 2~6 weeks after the injury can be bone – the outer membrane of the formation of bone-like – fibrous tissue connections, followed by neovascularization into the gradual solidification of the formation of the original bone scab, at this time generally in the fracture of 12~24 weeks, generally in the X-ray can be seen in the formation of the bone scab, but can still see the fracture line. It can be seen that the reason why sometimes the fracture line can be seen early after the fracture is because the fracture is not completely connected by the bone scab and healing, during the period of time the speed of the formation of the bone scab varies from person to person, and it usually takes up to 24 weeks to be completely closed. If the time to closure is extended to 9 months and the fracture line is still visible, it means that the fracture has delayed healing or does not heal. If the fracture line is visible in the lateral ankle at 2 months, it is recommended that the fracture be reviewed periodically, before and after, to see how the fracture is healing.
