Still too busy to spend lots of time blogging... So, today I'll just post a couple of photos of a fairly well-known medical condition, often (but not always) associated with a specific genetic disorder.
Syndactyly is a condition where two or more digits (fingers, toes or both) are fused together. While not as crippling as lacking a limb or part of a limb, it impairs mobility and function to some extent.
Syndactyly can be simple or complex.
- In simple syndactyly, adjacent fingers or toes are joined by soft tissue.
- In complex syndactyly, the bones of adjacent digits are fused.
- In complete syndactyly, the skin is joined all the way to the tip of the finger
- In incomplete syndactyly, the skin is only joined part of the distance to the fingertip
And here are the pictures:

Above, you can see the fused fingers on the hand of a 27-month-old girl with Apert syndrome. The child also displayed other characteristic features of this disorder, including facial hypoplasia, mild exophthalmus (bulging eyes) and mental retardation. Her fingers were separated surgically using an abdominal skin graft.
And another one, showing the fused digits on a child's hands and feet:

On the X-rays, you can clearly see that the bones are fused, not just the soft tissues. I've always been mildly fascinated by the odd appearance of these limbs.
And a third photo. These hands and feet belong to a 1-year-old girl with Apert syndrome.
