This ongoing care is important to identify any future problems that may occur, such as a recurrence of the dysplasia or early arthritis. grade 3: marked joint space narrowing, small osteophytes, some sclerosis. grade 2: definite joint space narrowing, defined osteophytes and some sclerosis, especially in the acetabular region. grade 1: possible joint space narrowing and subtle osteophytes. Depending on your child’s age, they may undergo imaging tests such as an ultrasound or X-ray to confirm the diagnosis and determine the severity of your child’s hip dysplasia.Īfter treatment for hip dysplasia, your child will continue to see their pediatric orthopaedic surgeon periodically to ensure their hips are developing properly. Different grading schemes are described for plain radiographs of the hip: grade 0: normal. Our pediatric orthopaedic surgeons will conduct a thorough history and physical exam. Differences greater than 1.5 mm between the two sides are considered abnormal. Our pediatric surgeons work with a team of nurses and specially trained pediatric staff who are up to date on the latest developments in the field and treat families from across the state who come to us for their children’s care.ĭetermining the Severity of Hip Dysplasia Referral to a Pediatric Orthopaedic Surgeonĭepending on the severity of your child’s condition, test results, and risk factors, they may be referred to a pediatric orthopaedic surgeon who has undergone special training and is skilled in treating children with musculoskeletal disorders like hip dysplasia. That’s because these risk factors or signs of hip dysplasia on their newborn screen may have mild cases that go undetected and progress as babies grow and toddlers begin to walk. If a child is older than 3 months or 13 weeks, then an alpha angle of 50-59 degrees is considered a sign of dysplasia, i.e type IIb. So an alpha angle of 56 degrees at the age of 7 weeks is called type IIa+, while at the age of 10 weeks it is called a type IIa. Babies with these risk factors are often referred for an ultrasound of their hips regardless of their screening exam results. A type IIa- hip is at risk to develop dysplasia. All of those discharged were subsequently X-rayed at 5. Using ultrasound to determine the depth and shape of the hip socket can accurately predict which infants with hip dysplasia will develop normal hip. The diagnosis of developmental hip dysplasia can be obvious but may sometimes be subtle, with a normally shaped femoral head and neck that simply lack sufficient coverage by the acetabulum. Any child with an ultrasound scan showing Graf -angles greater than 60° (Graf Type I) with the hip in joint were discharged from the clinic. Anyone can be born with hip dysplasia, but low levels of amniotic fluid in the womb during pregnancy, breech positioning, and a family history can increase your child’s chances of developing the condition. Between 19 in Nottingham, UK, out of a total population of 108,500 births, approximately 11,500 neonates were screened using ultrasound.
