Can you have extra bones in hands?

Yes, it is possible to have extra bones in the hands. This condition is known as polydactyly and occurs when a person is born with more fingers or toes than normal. Polydactyly can be caused by genetic factors or environmental factors such as exposure to certain chemicals or medications during pregnancy. In most cases, extra bones in the hands are harmless and do not cause any pain or functional problems. However, in some cases, extra bones can interfere with the movement of the hands or cause pain, which may require surgery to remove the extra bone.
