One relates to the success of the operation. This is the most important premise!
The second one is related to physical fitness. Young people, people with good health and mild illness may be faster, on the contrary, they will be slower.
Third, it is related to the treatment method. Western medicine can't cure this disease, but Chinese medicine can.
Fourth, it is related to the efficacy of the drugs used by doctors. This is the most important and critical factor. As far as I know, if other factors are excluded, patients with spinal fractures (including comminuted and compressive fractures) can start sideways in 5 days, sit up in bed in 7 days and walk on the ground in 9 days without surgery, and start functional recovery training in the best treatment period.
For more details, please visit this space. See the article, such as bed rest-a helpless move of spinal fracture. Treating spinal fracture is a unique skill of Chinese medicine, and it has little effect on refuting bone injury drugs. There are many cases of cure for reference, which I believe will inspire you.
I wish you a speedy recovery!
