Is bruises and wounds and wounds on leg means leg bone fracture or break? what symptoms should a broken or fractured leg bone be?

Varies: Bruises signify bleeding in the soft tissues and can certainly be oresent without a break in the leg. Symptoms from a broken leg vary quite a bit based upon the severity and location of the fracture, but certainly if you can't bear weight on your leg that would be a concern. Don't hesitate to be seen if you have any question. An exam and X-ray will give a lot more information.

Have it x-rayed: Can't tell for sure without at least an x-ray or in some cases further radiographic studies. This needs to be evaluated. The wounds are also cause for concern, especially if deep or infected. Get medical attention immediately,
