Closed reduction guided by dynamic ultrasound in late-diagnosed hip dislocation.

The potential for dynamic ultrasound in the primary treatment of late-diagnosed congenital hip dislocation was assessed in 21 patients. The study showed that dynamic ultrasound was a useful technique in guiding closed reduction and for assessing the effects of positioning on the stability of children less than 2 years of age. In older children, however, this assessment was less reliable. Although dynamic ultrasound evaluation can be done without sedation, general anesthesia provides optimal conditions for such evaluation. The benefits of ultrasound are that it does not involve exposure to radiation, that the need for elaborate radiographic methods like arthrography and computed tomography is reduced, and that closed reduction is more reliably achieved when guided by direct visualization. Because a thorough knowledge of the dynamics of hip dislocation is essential, the ultrasound evaluation should be performed by orthopedic surgeons.

Earliest diagnosis of congenital dislocation of the hip by ultrasonography. Historical background and present state of Graf's method.

Since Graf in 1978 introduced sonography into examination of hip dysplasia and hip dislocation, we survey an experience of more than 38,000 infant hips. At the present sonography of the infant hip is a standard and superior to traditional diagnostic methods especially in infants under three months of age, if the following minimum requirements are fulfilled: 1. THEORETICAL AND PRACTICAL TRAINING OF THE METHOD: anatomic identification (landmarks, standard situation, standard plane), description and nomenclature of the sonographic hip types according to GRAF, measurement (bony roof angle "alpha", cartilage roof angle "beta"), dynamic examination, therapeutic consequences and follow-up, points of weakness and errors of measurement. 2. CERTAIN TECHNICAL STANDARDS OF THE ULTRASOUND INSTRUMENT: linear scanner, 5 MHZ (newborn: 7.5 MHZ). POSITIONING-DEVICE (patent: Fa Radl, A-8010 Graz-Austria) 3. SUFFICIENT DOCUMENTATION: projection similar to a ap-radiograph of the right hip, image scale never less than 1:1, black on white, two ultrasound scans per hip in the standard-plane. Suitable Systems: multiformat, dry copy, computer printout. Follow-up-studies have proved that in our region approximately five percent of hips under the age of three months require treatment, and that prognosis is better the earlier therapy is started. For this reason we recommend a sonographic screening of the newborn not later than six weeks of age.

The importance of sonography and radiography in diagnosis and treatment of congenital dislocation of the hip.

The advantages of the sonography of the hip joint in the diagnosis and treatment of hip dysplasia in 1992 "policlinic" children and 1100 newborns are discussed and compared with radiological methods. The treatment concept at the Orthopädische Universitätsklinik Bonn is described as well as its modification after introduction of the sonography in the hip dysplasia screening-examination. These results confirm the necessity of making an early diagnosis. The osteonecrosis of the hip as a complication of the treatment of hip dislocation is discussed.

Ultrasound examination for the early determination of dysplasia and congenital dislocation of neonatal hips.

Hip sonography enables an accurate and clinically relevant evaluation of hip maturation during the first days of human life. Experience has shown that an integration of hip sonography into neonatal screening programs is useful and necessary because clinical and even roentgenographic examination does not always establish a confirmed diagnosis of dysplasia.
