There is no penalty that would occur if you undergo facet injections. It is highly unlikely these injections will work as the facets are “disconnected” from the vertebra due to the pars fractures. Nonetheless, if you want to try them, there is very little down side (other than the cost and the highly unlikely possibility of infection).
I would not want you to have both surgeries at the same time. The anesthesia time and amount of different rehab procedures necessary post-operatively would be too much to accomplish.
After fusion surgery of the lumbar spine, you are generally in the hospital for 2-3 days and I would want you to stay in the Vail Valley for another 3-4 days before you fly home.
