I understand your concerns about big toe joint fusion and how it might impact your walking. I haven't had the procedure myself, but I've done some research and spoken to others who have undergone it.
Fusion is often recommended because it can provide long-term relief from pain and improve stability, especially when arthritis is advanced. While it's true that fusion will limit the movement of your toe joint, many people adjust their walking pattern over time. Some have reported that the initial adjustment period can lead to temporary discomfort in the knees, hips, or back, but physical therapy and proper footwear can help mitigate these issues.
In addition, some people find that nature meds supplements can support joint health and alleviate inflammation, though it's important to consult with your doctor before starting any supplements, especially when planning surgery.
It might also be worth discussing with your consultant if there are any specific exercises or supports you can use post-surgery to help with your gait. Hearing from others who have had the procedure and speaking with a physical therapist might also give you a clearer idea of what to expect.
