Developmental dysplasia of the hip (DDH) is a common congenital problem affecting up to 3% of the the population. If untreated, DDH may lead to hip dislocation and premature osteoarthritis. Current DDH diagnosis is highly operator-dependent as it relies on 2D ultrasound. 3D ultrasound offers more complete, and potentially more reliable, imaging of infant hip geometry. However, it is unclear whether 3D ultrasound images, noisy with artifacts and reconstructed by proprietary algorithms from non-parallel beams, give accurate 3D shape information. We sought to validate the fidelity of acetabular surface models obtained by 3D ultrasound by comparison with those obtained concurrently from MRI. Read More

This technical innovation describes our institution’s standardized technique for palliative steroid injections in children with symptomatic neuromuscular hip dysplasia. Children with neuromuscular hip dysplasia are at risk for developing painful hip dislocation, which can dramatically affect their quality of life. Read More

Developmental dysplasia of the hip (DDH) is the designation given to a spectrum of structural changes in the developing hip. Ultrasound is the preferred imaging method for screening this condition in newborns and children under 1 year old. Pubofemoral distance (PFD) has been proposed as a new screening method for developmental dysplasia of the hip. The aim of this study is to assess the accuracy of PFD for developmental dysplasia of the hip using the Graf method as reference standard. Read More

Evaluating the alignment and blood flow in the femoral head in patients with congenital hip dysplasia following reduction is essential to the treatment of dysplastic hips. Current practice involves an immediate postoperative contrast enhanced MRI of the casted child to identify hips that may be at risk for avascular necrosis. Contrast enhanced ultrasound (CEUS) is an emerging imaging modality that is feasible to evaluate the perfusion of the cartilaginous proximal femoral epiphysis intraoperatively, after hip reduction and prior to spica casting. This educational exhibit describes the procedure of intraoperative CEUS of the hip from the sonographers’ perspective. Read More

Hip ultrasonography is now considered the main method for screening, diagnosing and monitoring the treatment of development dysplasia of hip (DDH) in children, considering the advantages of the method and the excellent characterization of the anatomical elements of the infant hip which, at this stage of life, consists largely of cartilage. In 1980, Reinhard Graf, an Austrian pediatric orthopedist published child hip study work from about 20,000 stillbirths. He evaluated and studied through hip ultrasound the hip joint and determined in a single coronal section the hip classification. The purpose of this article is to explain in a didactic and detailed way the method of Graf, focusing on the reference points for its realization and proper interpretation. Read More
