What is Symbrachydactyly?
Symbrachydactyly is a rare congenital defect of the hand characterized by short, underdeveloped and webbed fingers. The condition usually affects one hand, often the left and may affect boys as well as girls. There are different types of symbrachydactyly based on the severity of the condition. The fingers are sometimes so underdeveloped that they appear absent or as small stumps.
Causes of Symbrachydactyly
In most cases, the cause of symbrachydactyly is unknown and it does not seem to be hereditary. It is sometimes associated with a genetic syndrome called Poland syndrome in which the child also has underdevelopment of one side of the chest.
Symbrachydactyly is mostly identified at birth though it may also be noticed on prenatal ultrasound scanning. To evaluate the condition, your doctor will perform X-rays of your child’s hand.
Treatment for Symbrachydactyly
Treatment depends on the severity of the condition It may involve soft tissue correction to separate the fingers or surgery to lengthen the fingers and improve function. Surgery to separate the fingers may be performed when your child is 1-2 years old. A bone transplant may be required to lengthen the fingers if the condition is severe. Usually the bones of the toes are used. The goal of the procedure is to give your child the ability to hold or grasp objects. Additional procedures may be required as the child grows.
