Renowned pediatric orthopedists and geneticists at Nemours Children’s Hospital in Orlando provide comprehensive care for children with primordial dwarfism, a group of rare conditions that affect growth and development in the earliest stages (while in the womb). Children with primordial dwarfism are born smaller than average due to slow prenatal growth or intrauterine growth, and depending on the type of primordial dwarfism, have developmental features that may include small head size, prominent facial features (such as eyes and nose), spinal curvature (scoliosis) and rounding (kyphosis) and fine, sometimes sparse, hair.
At Nemours, our goal is to help children with all forms of skeletal dysplasia achieve the highest level of mobility, function and health possible. Here, you’ll find doctors, surgeons, counselors, nurses and staff who are uniquely qualified and share a strong commitment to your child’s long-term health and wellness. As a team, we work together to manage the physical, emotional and social complexities that come with this condition, and to provide maximum ability and freedom as your child grows and develops.
Expert Care for Children With Primordial Dwarfism in Central Florida
Primordial dwarfism is an extremely rare condition and only a handful of hospitals in the country treat children with this condition. At Nemours Children’s Hospital, we evaluate children with all types of primordial dwarfism — including Russell-Silver syndrome, Seckel syndrome, Meier-Gorlin syndrome and Majewski osteodysplastic primordial dwarfism (MOPD) types I and II — from a genetic and orthopedic perspective.
Primordial dwarfism is caused by a genetic change (or mutation) in two copies of specific genes (one from each parent) important for normal growth and development. The genetic mutation may differ depending on the type of primordial dwarfism. In Majewski osteodysplastic primordial dwarfism type II (MOPDII) for example, the pericentrin gene (PCNT) is involved.
Primordial dwarfism is a form of dwarfism marked by proportionately small stature. In addition to short stature, small head size, spinal deformities and prominent facial features, primordial dwarfism may also cause dislocated knees, hips and elbows, loose joints, delayed bone age and other skeletal abnormalities such as asymmetry (different size limbs) and deformities in the fingers and toes.
Infants and children with primordial dwarfism can have problems feeding, abnormalities of the skull and brain and early puberty. Your Nemours team of specialists will look for and assist in managing these symptoms.

Evaluating Primordial Dwarfism in Infants and Children
Primordial dwarfism can be diagnosed in utero, or while the baby is still in the womb. Your child’s evaluation for primordial dwarfism at Nemours Children’s Hospital will begin with a diagnostic appointment with one of our pediatric orthopedic experts in skeletal dysplasias. We can often make a diagnosis in our initial evaluation, but, depending on your child’s condition, we may recommend additional diagnostic testing and further evaluation with a geneticist.
Because of the complexity involved in making a firm diagnosis in some types of skeletal dysplasias, including primordial dwarfism, a great deal of information is collected at the initial visit, so it may take an hour or two to complete. During your visit, we’ll:
- obtain your child’s medical history and a three-generation family medical history
- review your child’s medical records and previously obtained X-rays
- perform a physical examination, including detailed measurements of your child’s joint motions (how much each joint can move) and the lengths of arm and leg bones
At Nemours Children’s Hospital we provide advanced testing to help us diagnose primordial dwarfism and develop an effective treatment plan based on your child’s specific needs. Tests may include:
- imaging: X-ray, ultrasound, CT (computed tomography) and MRI (magnetic resonance imaging)
- biochemical tests: determine levels of critical proteins in a sample of blood, urine or other fluid or tissue
- molecular tests: determine a child’s genetic makeup and confirm the clinical diagnosis
Treating Primordial Dwarfism
Skeletal dysplasias, including primordial dwarfism, are often associated with complex medical and surgical needs. At Nemours, we have an experienced team of health professionals and well-equipped facilities to provide convenient, comprehensive multispecialty care for your child and family.
While there is no cure or simple treatment for primordial dwarfism, in some case, surgical procedures may increase mobility and relieve (and prevent) related complications. We’ll work with your family to help you understand the available treatment options.
To help make the experience as comfortable as possible, we also provide emotional and psychosocial support and many other services for your child and family, including:
- social work
- Child Life services
- KidsTRACK care coordination
- mental health counseling
- patient and family education
- spiritual care
- support groups
A Hospital Designed by Families, for Families
At Nemours Children’s Hospital, family-centered care is at the heart of everything we do. In fact, families helped shape the unique amenities and convenient services that make our hospital like no other in the region.
You’ll feel right at home in one of our private patient rooms designed with input from families who know what it’s like to have a child in the hospital.
Our large, comfortable, single-patient rooms have sleeping accommodations for two parents, a private bathroom, wireless Internet access, connections for DVD players and game systems, and two flat-screen TVs.
Other in-room features include:
- full floor-to-ceiling windows for natural light
- refrigerator for family meals and snacks
- wardrobe storage for personal items and a hotel-style safe
- GetWellNetwork interactive television (uniquely based on your child’s age, medical condition and more) and allows your child to watch TV, surf the Web, check e-mail, play music and games, and learn about your Nemours health care team.
Our “hospital within a garden” setting features many places for you and your family to go for fresh air and relaxation, including a one-acre interactive sensory discovery garden or one of our rooftop gardens on the second and fourth floors.
We have many more comforts and amenities such as:
- complimentary valet and parking
- kid-friendly commons areas for siblings
- café and coffee shop
- nondenominational chapel
- concierge services
If your child needs medical imaging, we offer some of the area’s most advanced pediatric radiology services here on campus at Nemours
Our unique services include:
- interventional radiology: Our team of experts uses image guidance to diagnose and treat diseases and tumors throughout the body. Certain conditions that previously required open surgery can now be treated by Nemours pediatric interventional radiologists. We are very fortunate to have the only dual-trained pediatric diagnostic and interventional radiologist in the state.
- neuroradiological or cardiovascular imaging, and fetal MRI (magnetic resonance imaging): Our subspecialty-trained pediatric radiologists see children with complex conditions who require this highly specialized imaging.
- Central Florida’s only 256-slice Brilliance iCT Scanner: We are one of only a handful of children’s hospitals in the country to have this latest generation CAT (or CT) scanner that scans faster than most machines and produces excellent images in a much shorter time with much less radiation exposure for the child.
Our team of board-certified pediatric radiologists and pediatric radiologic technologists are experts in the safe medical imaging of children of every age, even newborns.
We have also pledged our commitment to the “Image Gently” campaign of the Alliance for Radiation Safety in Pediatric Imaging, which is increasing awareness of the opportunities to promote radiation protection in the imaging of children.
At Nemours, we want to hear your concerns and share with you everything we can about your child's condition and treatment. If English is not your first language, we'll make sure you understand what to expect — in your language.
