I recommend BMP for a fusion in the lumbar spine as this substance does promote fusion very well. Your surgeon might have a 98% fusion rate but there is no way to confirm this unless he has written a paper in a peer reviewed journal.
Normal fusion of the lumbar spine in my hands takes about five months.
I do not understand why he or she does not like pedicle screws. The posterior approach allows decompression of the nerve roots and much better fixation of the two levels. If he or she is comfortable with an ALIF, again there is nothing wrong with this technique but for the aforementioned issues.
There is no change in the “level of arthritis” from an anterior or posterior fusion of the lumbar spine.
The Titan spine implant is an interbody spacer device designed to have bone grow into it. I generally do not like metal devices as X-rays cannot determine if there is a solid fusion.
