I find it interesting that most children with an extra finger next to the pinky are not treated by a hand surgeon. The extra digits are routinely "tied- off" in the newborn nursery. Rarely these children may be treated in the pediatrician's office or at an orthopedic surgeon's office. And most of these kids do really well, although small signs of the extra digit remain years later. However, this treatment is best for the small extra digit and not the fully formed digit which requires a more formal surgery.
There is a huge variety in how the extra finger may appear- from quite small to normally sized. The position and development of the extra digit is also variable as noted in this excellent article in the medical literature.
|This child has a fully formed extra digit next to his pinky.|
|Smaller (and a bit swollen) extra finger.|
|Another type of extra digit, this time coming off the small finger closer to the nail.|
So, no matter whether the extra digits is "tied- off" in the newborn nursery, clipped in the clinic or treated with formal surgery, most patients do great.
