Having surgery March 30th, have question?

Recommended Posts


My mother is 73 years old and is up for stage 2 of her surgery on Friday. I was unable to attend stage one, which was 6 bone screws, MRI, CT, and Lab. My question that I could not get an answer to due to my absence is, why 6 bone screws? I was under the "assumption" that the large ring used at the time of surgery only required 4 screws (2 in back and 2 in front). The screws in my mothers head are across from ear to ear and across her forehead. Why in that location and what are they for?


I am just feeling a bit worried and was curious as to why so many were used. If you can explain possibly why they would be needed or direct me to where I may read more information, I would greatly appreciate your input.


Thank you so much for your time and attention in this matter.

If this is a DBS surgery, the best thing to do is to address this question directly to the surgeon.


Stage one is where they usually place a head ring with four screws to temporarily attach it to the skull. There are frameless DBS systems that require implantation under the skin of several markers that an apparatus will eventually attach (perhaps yours is frameless).


Many people do this procedure with many variations so it is best to ask your specific team.


Good luck.


By the way, part I in our center is lead placement using a frame, and part II is the battery placement--no frame needed.


Perhaps in your case part I is placing markers for a frameless system and part II is lead placement. I of course am guessing.
