At present, there are more than 200 kinds of technologies to treat the big foot bone in China, and the most common ones are traditional and minimally invasive. The traditional operation of removing the big foot bone requires osteotomy and fixation with steel nails, and the steel nails need to be taken out again after recovery, which is very harmful to the foot. At present, our patented micropore surgery for removing the big foot bone only opens two 2-3 cm micropores at the position of the bony process, removes the bony process, and resets the joint for bandaging and fixation. The recovery effect is good.
