Polymelia is a rare condition where a baby is born with extra arms or legs. Key points: • The extra limbs can be fully formed or only partly developed. • It can happen because of problems during early development, genetic changes, or if twins don’t fully separate (the extra limb may come from a “parasitic twin”). • Doctors can often see it before birth using ultrasound or MRI. • Surgery is usually done in early childhood to remove the extra limb for better movement and appearance. #reelsfbシ #hig
