When it comes to treatment it is important to differentiate a<unk>  that needs stability, more web width and function, or a<unk>  that needs to be replaced by the index finger. Severe<unk>  is best treated by pollicization of the index finger. Less severe<unk>  can be reconstructed by first web space release, ligament reconstruction and muscle or tendon transfer. It has been recommended that pollicization is performed before 12 months, but a long-term study of pollicizations performed between the age of 9 months and 16 years showed no differences in function related to age at operation. It is important to know that every reconstruction of the<unk>  never gives a normal<unk> , because there is always a decline of function. When a child has a good index finger, wrist and fore-arm the maximum strength of the<unk>  will be 50% after surgery in comparison with a normal<unk> . The less developed the index finger, wrist and fore-arm is, the less strength the reconstructed<unk>  will have after surgery.
