Indeed, hand deformity involves abnormalities of bones and joints, tendons, skin and nails. Take the most common deformity of polydactyly as an example, if only the multiple fingers are removed, without rebuilding the stability of the finger joints or correcting the tilt of the joints, the child will definitely have symptoms such as unstable pinching and weakness of the fingers in the future, and the corresponding appearance will be unattractive and affect the physical and mental development of the child. In contrast, the bones and tendons of the fingers of children from a few months to a couple of years old are really small, and we are able to perform operations such as osteotomies with microscopic hand surgery instruments and miniature power systems. Therefore, we hope that parents will choose a physician with experience in pediatric orthopedics and related hand surgery to receive treatment, rather than rashly treating the child, which may affect subsequent treatment and leave lifelong regrets.
