As for your specific questions about cement and anesthesia, in my experience that varies somewhat from doctor to doctor and maybe even facility to facility. I know overall the facility I use would rather use spinal sedation as they've found it's better for patients than a general, but they let the patient decide which they are more comfortable with. I've always had GA for surgeries, but for my revision the anesthesiologist took a lot of time right before my surgery to explain the differences between, and advantages of, each. I'd always rejected the spinal as I never wanted any possibility of waking, but he explained the spinal and different levels of sedation to me so well that I actually chose a spinal with deep sedation for the revision. And I was so happy I did afterwards! I was out totally for the entire procedure, and woke right up afterwards with zero side effects, unlike every GA I've ever had where I took hours and hours to wake, and then was overly groggy and ill. With the spinal I was clear-headed and wide awake right away and had no nausea or vomiting, plus went to my room right away, whereas with GAs I'd always been in recovery for at least 4 hours, and often longer. If you want to be awake during the procedure (shudder), you also have that option at my facility.
As for the cement, I think that varies with the surgeon, it's something to put on your list of questions for the OS when you see him.
