This child has symbrachydactyly with a single digit (monodactyly type). The thumb tip is flexed and he cannot straighten it. His other extremity is normal. Overall, he functions well. The question that we discussed with the family is whether anything could be done to further improve his function. Note the small palm which is typical in symbrachydactyly.

Our team had discussions with the family and observed his function with activities. Given that the thumb would not extend, together we all decided to position the thumb in extension with a stiffening of the joint (like a fusion but given the bony immaturity, technically not a fusion). This more extended position should help with activities and will allow the patient to better use the hand for function.

The pins will be in place for about one month and then he will use a splint temporary. We look forward to this straightforward surgery improving function.
