AIM Hip sonography is today considered to be the diagnostic standard tool for developmental dysplasia of the hip (DDH) diagnosis. In Germany special commissions control the quality of the sonograms according to checklists to keep the standard high and to avoid over- and under - treatment. This paper lists tips and tricks to avoid typical mistakes according(More)

Sonography of the hip in infants is being increasingly employed. This method of examination involves several specialist disciplines. The more widespread its use, the greater the likelihood of faulty diagnoses if one is not aware of its weak points. Faulty diagnoses are the order of the day if the method is employed by persons whose knowledge has not been(More)
OBJECTIVE Supine positioning of the patient taking into account - the demands of anesthesia in an emergency requiring intubation, - minimal time for sterile draping, - patient position can be adjusted by the assistants, - easier implant positioning due to the supine position. Reduction of operative trauma with earlier mobilization and shorter rehabilitation(More)

The purpose of the study is to clarify the access route that is most suitable in sonography of the infant hip for diagnosis of luxation and dysplasia. The process of luxation gives rise to deformation of the hyaline cartilaginous preformed part as well as the osseous acetabulum. These deformations are located in the superoposterior part of the acetabulum.(More)

Hip sonography in the "Graf technique" is an important tool to detect early DDH cases and dysplastic hips in the German speaking countries, although hip sonography is still controversially discussed in the English speaking countries. The reason may be different techniques with different classification and outcome. Exact anatomical identification,(More)

In Europe, the use of ultrasonography has become a routine procedure for the detection of hip dislocations and dysplasias; clinical and historical data alone are not fully reliable. Under the right conditions, ultrasonographic examination of the hip can reliably detect hip joints in need of treatment. Furthermore, results are reproducible without the use of(More)
Sir, This letter is to outline the position of representatives of the German-speaking countries, particularly from Austria, with regard to screening US for developmental hip dysplasia. This letter is in response to the recommendations on hip screening from the European Society of Paediatric Radiology (ESPR) task force on developmental hip dysplasia(More)
The author reports on hip-joint examinations in 16 000 infants, using sonography (age: 1 day up to 12-15 months). Particular attention is given to the classification of disturbances of maturation of the hip joint described. The use of angles and the possibility of making mistakes during measurement are demonstrated. The ultrasonographic traces are compared(More)
