CT scans are not typically used for diagnosis but may be used to confirm hip position after treatment. A CT scan shows detailed images of the hip and can help assess the three dimensional shape of the bones and joint. Computed tomography scan (also called a CT or CAT scan) - A diagnostic imaging procedure that uses a combination of x-rays and computer technology to produce cross-sectional images (often called slices), both horizontally and vertically, of the body.This is the standard test used to diagnose or monitor DDH after 6 months of age. X-ray - A diagnostic test which uses invisible electromagnetic energy beams to produce images of the hip joint.This tests uses no radiation and is best when for younger infants in whom most of the hip joint is still made of cartilage (<6 months of age) Ultrasound (also called sonography) - A diagnostic imaging technique which uses high-frequency sound waves and a computer to create images of the baby hip joint.However, DDH may not be discovered until later evaluations and not all hip dysplasia can be determined by physical examination alone. During the examination, the physician obtains a complete prenatal and birth history of the baby and asks if other family members are known to have DDH. Your baby's physician may make the diagnosis of developmental dysplasia of the hip with a clinical examination. The pediatrician or newborn specialist screens newborn babies in the hospital for this hip problem before they go home. During adulthood, residual shallowness in the hip socket is thought to be the number one cause of arthritis and therefore the most common reason for why an adult may require a hip replacement (artificial joint).ĭevelopmental dysplasia of the hip is sometimes noted at birth. Pain and leg length differences can develop during adolescence. Depending on the severity of hip dysplasia, a child may have a limp or “waddle” with walking or running. If unrecognized until later in life, children with DDH will still typically learn to walk at a normal age. A “clunk” felt with diaper changes or other positioning of the leg.The folds in the skin of the thigh or buttocks may appear uneven.The affected leg not spreading (abducting) as widely as the normal side.The leg that appears shorter on the side of the dislocated hip.Characteristic findings which raise a suspicion for DDH include: Hip dysplasia is painless during infancy and early childhood though it can cause pain and disability later in life if left untreated. Severe cases sometimes require surgery.The symptoms of hip dysplasia are often very subtle during the newborn period. Treatment for infants usually involves a soft brace that holds the ball portion of the joint firmly in its socket for several months while the bones develop. Ultrasound is also used to monitor treatment for hip dysplasia in infants. Ultrasound uses sound waves to create images of soft structures in the body, allowing a view of the baby’s hip joint and surrounding muscles, tendons, and ligaments that will show any “looseness” or dislocation. The definitive test for hip dysplasia in infants up to six months of age is a hip ultrasound. A child suspected of hip dysplasia will be referred to a pediatric orthopedist by his or her pediatrician. Hip dysplasia is most often diagnosed between six weeks and six months of age, though it can develop in children any time during their first year of life, and milder cases may be diagnosed much later. If left untreated, the condition can lead to arthritis or a hip labral tear (damage to the soft cartilage in the hip joint) in adolescence or adulthood. Babies born breech (feet-first) are at higher risk for hip dysplasia, as are girls and babies with a family history of the condition. According to the International Hip Dysplasia Institute, approximately one out of ten newborns will have some type of hip instability, and one out of every 100 infants will require treatment. Hip dysplasia-or misalignment of the bones or ligaments of the hip-is the most common developmental hip deformity in children. An ultrasound image of a baby's hip shows looseness or dislocation.
