Polydactyly, our treatment protocol is fixed. For floating thumb, we also have a set treatment plan. It is relatively simple if treated individually, but if a baby has both polydactyly and a floating thumb problem, how should it be treated? In such cases, we usually treat it in situ. What does that mean? It means that the baby’s polydactyly is preserved and not allowed to be discarded, and then it is used to reconstruct the missing metacarpal bone of the floating thumb. To achieve a more desirable surgical result, one, we need to carefully design the surgical plan, and two, we need to do a good job of post-operative functional exercises. We have done this surgery before, and when the baby came for a review not long ago, we found that he recovered well enough to write and hold small things, as well as to perform strong grasping and rotating movements. As a doctor, I think we have achieved the results of the treatment.
