How do injuries to the wrist ligaments occur?

By far the most common way the wrist is injured is a fall on the outstretched hand. (The same type of force can happen in other ways--such as when you brace your self on the dash before an automobile crash.) Whether the wrist is broken or ligaments are injured usually depends on many things, such as how strong your bones are, how the wrist is positioned during impact, and how much force is involved.
