This type of defect would most likely require a prosthesis for function when the child is older. Perhaps occupational therapy would be helpful to teach him/her how to function in some areas but the baby will likely learn to be quite resourceful on its own when given opportunity to play as any other child would.
There are various potential causes for such deformity such as infection, chorionic villus sampling, amniotic bands and teratogens such as seizure medications.
Fortunately children are amazingly resilient and can achieve great results when challenged and encouraged.
I hope this helps. I am not aware of any surgical intervention that could correct the defect.
