I’m not a doc, but I did work for an orthopaedic group that included a spine surgeon, and I have had two levels fused myself (L5-S1 in 2001, L4-L5 in 2004).
With that said, it took me about 6 months after each single-level fusion to feel normal again. I did not get back on a horse for about 8 months post op. I did not wear a brace after either surgery, but the posters above that stated you will have ZERO core muscles after this surgery… They’re absolutely correct.
This is a surgery where if you do not listen to your docs, and follow their instructions to the letter, you could potentially end up worse off than you are right now; especially if you start doing physical activity before you’re cleared by your doc (for said activity). And if you do fall off, whether it’s bucked off, or just falling from lack of muscle to stay balanced on your horse…
Let’s just say you really have to weigh the risk vs. benefit of riding. At 3 months, the risk is extremely high and the benefit is slim.
When the doc says you can start PT at 3 months - You will be surprised at how little you’ll be able to do at first. I was allowed to walk at first - THAT’S IT.
A 25 mile ride - Yes, eventually. But not 3 months post op. Set smaller, realistic goals. At 3 months post op, I attempted to curry my horse and found after a few minutes, my back muscles were in such spasm I ended up in bed for the next week.
Best wishes for your upcoming surgery & recovery. Sorry if I came across as blunt or harsh - but I am dealing with a possible third fusion due to possible herniated disc and/or a screw that migrated and is rubbing on the nerve root above the fusion. Waiting for a CT myelogram at the moment to see what’s going on & dealing with the frustration that is the health insurance industry.
If you need a listening ear, feel free to PM anytime. Again, best wishes.
