What is dwarfism? It means to be short in stature. Typically the average height for someone with this condition is: four feet, ten inches or less. Because there are several different health conditions that are link to dwarfism so this condition is broken down into 2 catogories. Disproportionate dwarfism. If body size is disproportionate, some parts of the body are small, and others are of average size or above-average size. Disorders causing disproportionate dwarfism inhibit the development of bones. Proportionate dwarfism. A body is proportionately small if all parts of the body are small to the same degree and appear to be proportioned like a body of average stature. Medical conditions present at birth or appearing in early childhood limit overall growth and development. It is also important to note: that people with this condition find it more acceptable to be called a little person or short in stature. This does not include familial short stature — short height that's considered a normal variation with normal bone development. Symptoms Aside from the short stature other symptoms can vary. Disproportionate dwarfism Most people with dwarfism have disorders that cause disproportionately short stature. Usually, this means that a person has an average-size trunk and very short limbs, but some people may have a very short trunk and shortened (but disproportionately large) limbs. In these disorders, the head is disproportionately large compared with the body. Almost all people with disproportionate dwarfism have normal intellectual capacities. Rare exceptions are usually the result of a secondary factor, such as excess fluid around the brain (hydrocephalus). The most common cause of dwarfism is a disorder called achondroplasia, which causes disproportionately short stature. This disorder usually results in the following: An average-size trunk Short arms and legs, with particularly short upper arms and upper legs Short fingers, often with a wide separation between the middle and ring fingers Limited mobility at the elbows A disproportionately large head, with a prominent forehead and a flattened bridge of the nose Progressive development of bowed legs Progressive development of swayed lower back An adult height around 4 feet (122 cm) Another cause of disproportionate dwarfism is a rare disorder called spondyloepiphyseal dysplasia congenita (SEDC). Signs may include: A very short trunk A short neck Shortened arms and legs Average-size hands and feet Broad, rounded chest Slightly flattened cheekbones Opening in the roof of the mouth (cleft palate) Hip deformities that result in thighbones turning inward A foot that's twisted or out of shape Instability of the neck bones Progressive hunching curvature of the upper spine Progressive development of swayed lower back Vision and hearing problems Arthritis and problems with joint movement Adult height ranging from 3 feet (91 cm) to just over 4 feet (122 cm) Proportionate dwarfism Proportionate dwarfism results from medical conditions present at birth or appearing in early childhood that limit overall growth and development. So the head, trunk and limbs are all small, but they're proportionate to each other. Because these disorders affect overall growth, many of them result in poor development of one or more body systems. Growth hormone deficiency is a relatively common cause of proportionate dwarfism. It occurs when the pituitary gland fails to produce an adequate supply of growth hormone, which is essential for normal childhood growth. Signs include: Height below the third percentile on standard pediatric growth charts Growth rate slower than expected for age Delayed or no sexual development during the teen years When To See A Doctor Signs and symptoms of disproportionate dwarfism are often present at birth or in early infancy. Proportionate dwarfism may not be immediately apparent. This is when you should speak with your doctor. Causes: Most cases of this condition are caused by a genetic mutation, but some causes of this condition are unknown to the those in the medical field. But this mostly occurs by a random genetic mutation that happens either in the father’s sperm or the mother’s egg. Rather than it happening from their complete genetic makeup. Achondroplasia About 80 percent of people with achondroplasia are born to parents of average height. A person with achondroplasia and with two average-size parents received one mutated copy of the gene associated with the disorder and one normal copy of the gene. A person with the disorder may pass along either a mutated or normal copy to his or her own children. Turner syndrome Turner syndrome, a condition that affects only girls and women, results when a sex chromosome (the X chromosome) is missing or partially missing. A female inherits an X chromosome from each parent. A girl with Turner syndrome has only one fully functioning copy of the female sex chromosome rather than two. Growth hormone deficiency The cause of growth hormone deficiency can sometimes be traced to a genetic mutation or injury, but for most people with the disorder, no cause can be identified. Other causes Other causes of dwarfism include other genetic disorders, deficiencies in other hormones or poor nutrition. Sometimes the cause is unknown. Disproportionate dwarfism The characteristic features of the skull, spine and limbs shared by most forms of disproportionate dwarfism result in some common problems: Delays in motor skills development, such as sitting up, crawling and walking Frequent ear infections and risk of hearing loss Bowing of the legs Difficulty breathing during sleep (sleep apnea) Pressure on the spinal cord at the base of the skull Excess fluid around the brain (hydrocephalus) Crowded teeth Progressive severe hunching or swaying of the back with back pain or problems breathing Narrowing of the channel in the lower spine (spinal stenosis), resulting in pressure on the spinal cord and subsequent pain or numbness in the legs Arthritis Weight gain that can further complicate problems with joints and the spine and place pressure on nerves Proportionate dwarfism With proportionate dwarfism, problems in growth and development often result in complications with poorly developed organs. For example, heart problems that often occur with Turner syndrome can have a significant effect on health. An absence of sexual maturation associated with growth hormone deficiency or Turner syndrome affects both physical development and social functioning. Pregnancy with dwarfism Women with disproportionate dwarfism may develop respiratory problems during pregnancy. A C-section (cesarean delivery) is almost always necessary because the size and shape of the pelvis doesn't allow for successful vaginal delivery. Diagnosing Dwarfism Your pediatrician will likely examine a number of factors to assess your child's growth and determine whether he or she has a dwarfism-related disorder. In some cases, disproportionate dwarfism may be suspected during a prenatal ultrasound if very short limbs disproportionate to the trunk are noted. Diagnostic tests may include: Measurements: A regular part of a well-baby medical exam is the measurement of height, weight and head circumference. At each visit, your pediatrician will plot these measurements on a chart to show your child's current percentile ranking for each one. This is important for identifying abnormal growth, such as delayed growth or a disproportionately large head. If any trends in these charts are a concern, your pediatrician may make more-frequent measurements. Appearance: Many distinct facial and skeletal features are associated with each of several dwarfism disorders. Your child's appearance also may help your pediatrician to make a diagnosis. Imaging technology: Your doctor may order imaging studies, such as X-rays, because certain abnormalities of the skull and skeleton can indicate which disorder your child may have. Various imaging devices may also reveal delayed maturation of bones, as is the case in growth hormone deficiency. A magnetic resonance imaging (MRI) scan may reveal abnormalities of the pituitary gland or hypothalamus, both of which play a role in hormone function. Genetic tests: Genetic tests are available for many of the known causal genes of dwarfism-related disorders, but these tests often aren't necessary to make an accurate diagnosis. Your doctor is likely to suggest a test only to distinguish among possible diagnoses when other evidence is unclear or as a part of further family planning. If your pediatrician believes your daughter may have Turner syndrome, then a special lab test may be done that assesses the X chromosomes extracted from blood cells. Family history: Your pediatrician may take a history of stature in siblings, parents, grandparents or other relatives to help determine whether the average range of height in your family includes short stature. Hormone tests: Your doctor may order tests that assess levels of growth hormone or other hormones that are critical for childhood growth and development. Health care teMental health provider, such as a psychologist or psychiatrist Nervous system abnormalities specialist (neurologist) Dental specialist in correcting problems with teeth alignment (orthodontist) Developmental therapist, who specializes in therapy to help your child develop age-appropriate behaviors, social skills and interpersonal skills Occupational therapist, who specializes in therapy to develop everyday skills and to use adaptive products that help with everyday activities A number of disorders causing dwarfism can cause a variety of developmental problems and medical complications. Several specialists may be involved in screening for specific conditions, making diagnoses, recommending treatments and providing care. This team may evolve as your child's needs change, and your family doctor or pediatrician can coordinate the care. Specialists in your care team may include: Hormone disorder specialist (endocrinologist) Ear, nose and throat (ENT) specialist Specialist in skeletal disorders (orthopedist) Specialist in genetic disorders (medical geneticist) Heart specialist (cardiologist) Eye specialist (ophthalmologist) Mental health provider, such as a psychologist or psychiatrist Nervous system abnormalities specialist (neurologist) Dental specialist in correcting problems with teeth alignment (orthodontist) Developmental therapist, who specializes in therapy to help your child develop age-appropriate behaviors, social skills and interpersonal skills Occupational therapist, who specializes in therapy to develop everyday skills and to use adaptive products that help with everyday activities Treatment The goal of treatment is to maximize functioning and independence. Most dwarfism treatments don't increase stature but may correct or relieve problems caused by complications. Surgical treatments Surgical procedures that may correct problems in people with disproportionate dwarfism include: Correcting the direction in which bones are growing Stabilizing and correcting the shape of the spine Increasing the size of the opening in bones of the spine (vertebrae) to alleviate pressure on the spinal cord Placing a shunt to remove excess fluid around the brain (hydrocephalus), if it occurs Hormone therapy For individuals with dwarfism due to growth hormone deficiency, treatment with injections of a synthetic version of the hormone may increase final height. In most cases, children receive daily injections for several years until they reach a maximum adult height — often within the average adult range for their family. Treatment may continue throughout the teen years and early adulthood to ensure adult maturation, such as appropriate gain in muscle or fat. Some individuals may need lifelong therapy. The treatment may be supplemented with other related hormones if they are also deficient. Treatment for girls with Turner syndrome also requires estrogen and related hormone therapy in order for them to begin puberty and achieve adult sexual development. Estrogen replacement therapy usually continues throughout life until women with Turner syndrome reach the average age of menopause. Growth hormone supplementation for children with achondroplasia does not increase final adult height. Ongoing healthcare Regular checkups and ongoing care by a doctor familiar with dwarfism can improve quality of life. Because of the range of symptoms and complications, treatments are tailored to address problems as they occur, such as assessment and treatment for ear infections, spinal stenosis or sleep apnea. Adults with dwarfism should continue to be monitored and treated for problems that occur throughout life. Limb lengthening Some people with dwarfism choose to undergo surgery called extended limb lengthening. This procedure is controversial for many people with dwarfism because, as with all surgeries, there are risks. Waiting to decide about limb lengthening until the person with dwarfism is old enough to participate in the decision is recommended because of the emotional and physical stress involved with multiple procedures. Lifestyle and home remedies Talk with your pediatrician or a specialist about at-home care. Issues particularly critical for children with disproportionate dwarfism include: Car seats. Use an infant car seat with firm back and neck supports. Continue using a car seat in the rear-facing direction to the highest weight and height possible (and beyond the recommended age limit). Infant carriers and play equipment. Avoid infant devices — such as swings, umbrella strollers, carrying slings, jumper seats and backpack carriers — that don't support the neck or that curve the back into a C shape. Adequate head and neck support. Support your child's head and neck when he or she is seated by holding the head, neck and upper back in a safe and stable position. Padding can help to provide the right position and support. Complications. Monitor your child for signs of complications, such as ear infection or sleep apnea. Posture. Promote good posture by providing a pillow for the lower back and a footstool when your child is sitting. Healthy diet. Begin healthy-eating habits early to avoid later problems with weight gain. Healthy activities. Encourage participation in appropriate recreational activities, such as swimming or bicycling, but avoid sports that involve collision or impact, such as football, diving or gymnastics. Coping and support If your child has dwarfism, you can take a number of steps to help him or her cope with challenges and function independently: Seek help. The nonprofit organization Little People of America provides social support, information about disorders, advocacy opportunities and resources. Many people with dwarfism stay actively involved in this organization throughout their lives. Modify your home. Make changes to your home, such as putting specially designed extensions on light switches, installing lower handrails in stairways and replacing doorknobs with levers. The Little People of America website provides links to companies that sell adaptive products, such as size-appropriate furniture and everyday household tools. Provide personal adaptive tools. Everyday activities and self-care can be a problem with limited arm reach and problems with dexterity. The Little People of America website provides links to companies that sell adaptive personal products and clothing. An occupational therapist also may be able to recommend appropriate tools for home and school use. Talk to educators. Talk to school personnel about what dwarfism is, how it affects your child, what needs your child may have in the classroom and how the school can help meet those needs. Talk about teasing. Encourage your child to talk to you about his or her feelings, and practice responses to insensitive questions and teasing. If your child tells you that bullying occurs in school, seek help from your child's teacher, principal or the school guidance counselor and ask for a copy of the school's policy on bullying. Preparing for your appointment How you learn whether your child has dwarfism will depend on the degree to which it affects his or her development. Disproportionate dwarfism is usually apparent at birth or early in infancy. Proportionate dwarfism may not be diagnosed until later in childhood or the teenage years if your child isn't growing at an expected rate. Well-baby visits and annual checkups It's important to take your child to all regularly scheduled well-baby visits and annual appointments throughout childhood. These visits are an opportunity for your child's doctor to track growth, note delays in expected growth and identify other problems in physical development. Questions your child's doctor may ask include: What concerns do you have about your child's growth or development? How well does he or she eat? Is your child reaching certain milestones in development, such as rolling over, pushing up, sitting up, crawling, walking or speaking? Are other members of the family very short, or have others experienced growth delays? Do you have your child's height marked on a measuring chart that you brought with you? Do you have photographs of your child at various ages that you brought with you? Talking to your doctor about dwarfism If your family doctor or pediatrician believes that your child exhibits signs of dwarfism, you may want to discuss these questions: What diagnostic tests will be needed? When will we learn the results of the tests? What specialists will we need to see? How will you screen for disorders or complications that are commonly associated with the type of dwarfism affecting my child? How will you monitor my child's health and development? Can you suggest educational materials and local support services for dwarfism?
