This is what my spine looks like, but at two levels:
I have the BAK/Proximity interbody fusion cages(pictured above).
There is no secret to maintaining mobility and staying practically pain free post-surgery.
I had two surgeries, one for the total dual level fusion and a second because a screw was coming out.
You do have to watch your weight.I don't because of an active metabolism.
Excercise and stretching can be very beneficial to your routine post-op.
I was up and walking the ortho unit 8 hrs after surgery and 1 mile daily before the staples were even removed.I can also count on one hand the number of narcotic pain pills I have taken post-op.
You just have to want it, man.The surgery can be very successful.Mine was.I still haul ass.
It's funny, cause the ones who I witnessed to bitch and moan that they were in severe pain post-op(and I witnessed many through Dr. visits, PT, etc) were overweight.
