Six fingers, also known as polydactyly, typically present as an extra digit on one hand or foot. It doesn't always look the same.
Appearance Variations
The appearance of a sixth finger varies considerably:
-
Fully formed digit: In some cases, the sixth finger is a fully formed digit, similar in structure to the other fingers, although it tends to be smaller. It might have a bone structure, joints, and even a nail. However, it often lacks the full range of motion and gripping ability of a typical finger.
-
Partially formed digit: Other times, the extra finger is only partially formed. This means it might be just a small nub of skin and soft tissue, lacking the typical bone structure and complete development of other fingers.
-
Location: The extra digit can appear on either side of the little finger or even in the middle of the hand. Its position influences its overall appearance and functionality.
-
Size and Shape: The size and shape of the extra digit are highly variable, ranging from small, rudimentary structures to digits almost identical in size and shape to the other fingers (but usually smaller, as noted in the provided reference).
Considerations
It's crucial to remember that polydactyly is a condition with a broad range of presentations. The appearance of a sixth finger is unique to each individual and can vary greatly depending on several factors.
The reference material mentions that a sixth finger is often smaller than other fingers and may lack the full functionality of a typical digit. It might even consist only of skin and soft tissue.
