Syndactyly refers to joined or “webbed” digits – in the hand, most often this refers to adjacent fingers which are grown together. Syndactyly is one of the most common variations on the basic growth pattern of the hand.

  • There are many different forms of syndactyly.
  • When the fingers are completely joined together, it is called “complete” syndactyly.
  • When the join involves only part of the sides of the fingers, it is referred to as “incomplete” syndactyly.
  • If the join between the fingers just involves the skin and flesh, it is described as “simple” (although it certainly isn’t).
  • If the bones are joined together, it is called “complex” syndactyly


Syndactyly occurs in the womb as a detour on the road to developing one thumb and four separate fingers on the hand. In the womb, the new hand starts out in the shape of a paddle, then splits into separate fingers. Sometimes the fingers don’t split apart enough, and webbed fingers result: syndactyly. Sometimes a extra split forms and extra fingers result: polydactyly. Syndactyly and polydactyly are about equally common disorders. Combinations of both can occur as well – webbed extra fingers. Why does a child have this? It is not due to anything the mother did during pregnancy – it just happens. Sometimes these problems are in the genes and can be passed down generation to generation, but many times there is simply no known explanation.

Physioline’s Treatment:-

A hand therapist can help with some problems before and after surgery, tailored to the individual problem and the temperament of the child. After surgery to separate fingers, a therapist can provide a special silicone rubber spacer, worn between the fingers while sleeping to help maintain the new web space during the healing process.
