    Dr. Corenman,

    I’m 5 weeks post XLIF with hardware L3-4. You mention cycling provided you do so in an upright position. Could you elaborate further on an acceptable position and duration, previously rode 3-4 hours daily prior to chronic nerve pain post car vs. bike accident. Currently walking 2 hours daily with no issues, but cycling is my passion. Don’t want a set back at this point. Thanks for any advice on this topic.

    My patients are allowed immediately to hop on a stationary bike (not flexed but upright) and start pedaling. Nothing hard but spinning is OK. Sweating is also OK as long as the dressing is off (normally at two weeks).

    I do not allow riding outside for 12 weeks to allow the fusion to mature and 16 weeks before climbing.

    Dr. Corenman,

    I have a follow up question regarding using a bike for exercise. Your patients resume riding outside at 12 weeks. Do you allow a more normal flexed position on the bike at that time? Sometimes a fall can occur,In your opinion would this bone be at more risk than others at this point? You say 16 weeks before climbing, is this due to the greater effort or the extra motion while standing? Thanks for your advice with this topic.

    I like the patient to change the stem length and height (shorter and higher) prior to their first adventure on the bike. I also prefer a mountain bike for initial riding on the street due to the impact absorption and reduced flexion of the lumbar spine. Yes-a fall can have impact on the fusion but at 4 months, the fusion should be more mature and able to tolerate a simple fall. Now a fall on a descent at 30mph is another story.

    Dr. Corenman, I have a question about exercise to promote bone growth of a lumbar fusion. I walked the first three months of recovery, now that I’ve resumed cycling 2-3 hours daily I’m thinking about discontinuing walking. Does the weight bearing aspect of walking promote more growth than cycling? I stand at least 30 min. of the cycling workout would this be sufficient or should I continue with the walking. Thanks for your advice on this topic.

    There is less loading on the lumbar spine from cycling vs. walking but after three months, bike path cycling on a full suspension mountain bike is recommended. It does not matter if the loading is low load vs. high load but I prefer cycling as a post fusion exercise.
