Part Of The Spine That Causes Urinary Problems Can Sacrum Still Be Snapped And Cause Urinary/bowel Problems?

Can sacrum still be snapped and cause urinary/bowel problems? - part of the spine that causes urinary problems

Question in two parts:
1 - Is it really takes 3 months to heal a broken cross / dislocation (3 to 4 of the bones)? After 2 months, may fall on this extension really is?
2 - Since the fracture below the joints, you can further damage to this or cracks that could lead to urinary, bowel and sexual problems?
I know that this part of the spine and therefore weak, but I do not know whether the document carefully.
