Last week, a mother brought a little boy to my clinic. The child had just entered the fifth grade and his right hand had a floating thumb, which made it very difficult for him to write. He used to try to write with his left hand, but he often made mistakes with his strokes. Later, he learned to write with his right hand, but because his thumb could not hold the pen, he usually relied on the clip to write, which had a certain impact on his learning. The parents were very distressed about their child’s difficulties, and they had been searching for a suitable surgical plan for their child for many years. The parents had learned about the bunionization of the finger and metatarsal reconstruction treatment plan, but after discussion, the family felt that it was not suitable, no matter after the operation, less fingers or from the foot knife to remove the bone, the cost for the child is quite large, parents can not bear to take the child to do the operation. Then the parents learned about hemi-metacarpal bone graft reconstruction on the Internet, and felt that this surgical option, which is performed only on the hand, would minimize the impact of the surgery, so they brought their child here. Many of the parents who brought their children to me basically said the same thing, because half-metacarpal bone graft reconstruction technique is to reconstruct the first metacarpal bone from the second metacarpal bone of the affected hand, the surgery will not add trauma to other parts of the child’s body, scars, or affect the function of the surgery, and the chance of bone resorption and necrosis of the surgery can be greatly reduced, so this is the more preferred of the various surgical options.
