Patient's question:
What are the common symptoms of dwarfism?Doctor's answer:
Chondrodysplasia is the most common form of congenital dwarfism, a developmental anomaly characterized by defective endochondral ossification while membranous ossification remains normal. It is an autosomal dominant genetic disorder, with over 80% of cases being sporadic. The signs are already apparent at birth, with dwarfism being the most prominent feature. Typical cases exhibit asymmetry in body proportions, primarily short limbs, especially the arms and thighs, while the trunk remains relatively normal. The head is large, the face is wide, and the forehead and bilateral top of the head are broad. The middle finger and fourth finger are separated, forming a "V" shape, known as "trident hand." The lower limbs are bent, but intelligence is normal. The final adult height, according to statistics, ranges from 112 to 136 cm for males and 112 to 136 cm for females.
