It is generally assumed that congenital malformations affect 1-2% of all newborns, 10% of which are in the upper extremities.
The most common malformation in the upper limb region is polydactyly. In rare cases, it is combined with syndactyly (webbed fingers). When congenital malformations occur in several regions or organ systems, one speaks of a syndrome.
(Did you notice that the hand on the right has 6 fingers?)
Congenital Hand Deformities
A 4 year old boy who is followed up by the Pediatric Department for a complex Congenital Hand Deformity Syndrome after open heart surgery. was referred to the Hand Surgery Clinic because of a bilateral polydactyly. At the right hand there were 6 normally developed finger .At the left hand he presented with 7 fingers, a complex combination of Polydactyly (Duplication of the middle finger and small finger) and a function-impairing syndactyly between the thumb and index finger. As the thumb function was significantly impaired by the webbing with the index finger, global grip/hand function was poor. A treatment plan was drawn up, and discussed in detail with both parents. .
After syndactyly release of the thumb and index finger, the skeletal elements of the index finger were removed, however the skin was used to reconstruct the most important 1 st web space. The non-functional duplicate of the middle finger was removed and the functional duplicate centralized over the common 3rd metacarpal bone, thus reconstructing the normal arches of the hand.
The patient was discharged from hospital 2 days after surgery. Modern Hand Surgery always is combined with adequate hand therapy/physiotherapy. 5 weeks after complex hand surgery play Therapy was started. The patient shows a dramatically improved grip function because of the reconstructed thumb and an increasing use of his transposed middle finger.
