I came across a short-fingered baby in my last clinic, and the parents asked comprehensive questions, which I’d like to share with you today. The baby was six months old and had exceptionally short fingers, with flesh but no bone in the finger area, and fortunately the metacarpals were all there. This is not a bad situation, we can help the baby to lengthen his fingers by turning up the metacarpal bones, so that he can do something with his hands in the future. Can I move my fingers after the metacarpals are turned up? The baby’s hand still has to have a little bit of strength. There are some stumps of the metacarpal tendon membrane and tendons in it, which we will leave in place during the surgery, and after the flip, we will suture them together and attach them. After the surgery, the child will have an overall ability to grasp, but the bending of the individual fingers will need to be trained slowly to obtain. Chen Jianghai, Department of Hand Surgery, Union Hospital of Tongji Medical College, Huazhong University of Science and Technology During surgery we will try to create extension and flexion of the baby’s affected hand as much as possible, and it’s very important that babies practice often after surgery. Will there be joints at the flipper after surgery? During the process of metacarpal reversal we will re-establish the joint for the baby so that it is cartilage facing the cartilage surface. After surgery the baby needs to exercise regularly so that the two cartilage surfaces can reach a more compatible state in the long term. How long does it take to recover after surgery? The recovery period after surgery takes almost three months, by this time the bone is basically stabilized, and after the Kirschner pin is removed, you can slowly start to move. Parents can help the baby to be passive in the beginning, and then slowly encourage the child to move on his/her own. You can give some things for the baby to play with, so that he has a little bit of grasping ability, things can not be too big, because if too big to grasp the baby does not want to play, parents mainly let the baby realize that the fingers can be used, he will be more and more willing to use. Can the metacarpal bone grow after it is turned over? How long does it take? The metacarpal bone can grow after reversal, and we have observed that it can grow back in about two years. What is the right age for short finger surgery? Firstly, the child should not be too old, because his ability to recover is not as good as that of a younger child. Secondly, the child should not be too young, like one or two months old, because he may not be able to meet the requirements of our surgery. We suggest that it is better to do the short finger surgery when the child is about one year old, at this time his metacarpal bone width generally meets the requirements of the surgery, and at the same time he can do better in the postoperative functional exercise, he can consciously grasp the activities, which is overall more advantageous.
