Good morning Doctor, My father met with an accident 4 days ago, two places got injured, 1. Head injury, brain nerves, x-ray shows blood clot at one place, from day one, he is in conscious and no vomits. In 3 times repeated CT scan report says, there is no increment in the blood clotting, so Doctor said, he is OK now, no need of any surgery, it gets cure with help of medicines only, you can go head for the broken bone surgery. 2. In X-ray reports, right leg below nee main bone got broken and beside nee another thin bone got displaced, doctor said, surgery with titanium rod, as it is an accident, as there is a wound at place of broken bone, doctor says there could be chances of septic. Why? What could be the right steps? Is brain nerves blood clotting could affect later time (or during broken leg surgery)?
