It all depends if your surgeon bought in a premade one or made it himself at the table. This is the premade oneMy spacer looks different from the ones you guys posted. It's very cylindrical like at the top not rounded?
Please let us know the results when they come in.
I can't imagine what you must have gone through once they cancelled your spacer removal due to your unsettling blood work. Since I am right behind you, this was extremely uncomfortable for me as well. But, you are fine and it's time for you to think forward to new beginnings, restored health, and happiness you overwhelmingly deserve!
