FAQ
Frequently Asked Questions
Yes, that is one form it can take (amelia), but dysmelia also includes shortened, reduced, or malformed limbs, not just complete absence.
No. By definition, dysmelia is a congenital condition, meaning it is present at birth. Limb loss or damage later in life is not called dysmelia.
No. It is a very low-frequency, specialized medical term. Most people will never encounter or need to use it.
Dysmelia refers to deficiencies in limb formation. Polydactyly is the presence of extra fingers or toes, which is an excess, not a deficiency, and is often classified separately.
