I have had a two-level spinal fusion (l5-s1). What is the best way to avoid (or prolong) adjacent disc disease?

Not much . Accelerated adjacent segment degeneration is relatively common and concerns adverse effects following spinal fusion. It is believed that this accelerated degeneration is due in large part to increased mechanical stress on the adjacent motion segments. Stay in shape, do not gain weight.
Not Well understood. I agree with the other providers but the reality is that "adjacent level disc degeneration" is not well understood. The stress from fusion may accelerate this by about 3%/year. However even with patients who have disc replacement over fusion get this condition as do patient who have simple laminectomy. Thus, there is likely a genetic component to who develops this and who does not.
Fusion. I think the best ways to help minimize that risk are to stay active with low-impact activities such as swimming, cycling and to maintain good core strength. It is also important to avoid jobs that require a lot of repetitive heavy lifting as that will ultimately cause more "wear-and-tear" of your back.

After having a failed laminectomy w/ spinal fusion @ l5-s1, what can't they surgically fix the area?

Failed back syndrome. Failed back syndrome (FBS) can be caused by many different factors. Laminectomies, in particular, have been shown to result in spinal instability in biomechanical studies. Minimally invasive surgery (mis) can help obviate some of the complications associated with fbs. Unfortunately, there may not be a quick fix in your particular situation. I would obtain a formal consult from a spine specialist. Read more...
Lumbar fusion. Failed can mean alot of things. Is it that you are not happy with the results? Or is there still a problem that is operative, i.e. Adjacent level syndrome at the level above the fusion or did the fusion not take at l5/s1 and there is a nonunion. I'm sure that your spine surgeon has discussed this with you. Read more...
