[Use of ultrasound in the early diagnosis of the syndrome of congenital dysplasia of the hip joint.].
The early diagnosis and correct treatment of the syndrome "Dysplasia coxae congenita" (DCC) is one of the fundamental chapters of orthopaedic child care. The author evaluates a group of 150 children examined by sonography to assess the possible presence of the DCC syndrome during the first trimester of life. The sonographic examination was made in three time intervals defined in advance: 1st check-up during the first-second week after birth; 2nd check-up at the age of 6-7 weeks and 3rd check-up at the age of 13 - 14 weeks. During the final evaluation a relatively large number of pathological findings was found at the age of 1-2 weeks, roughly in one third of the 150 examined children. This number is, however, markedly influenced by the number of 2+ findings. Group 2+ appears to be in the investigated cohort of children a "transient of unstable" group with possible spontaneous deterioration or spontaneous improvement of the original finding. Spontaneous deterioration of the finding in four children from the originally not affected children is also interesting. Spontaneous dererioration or spontaneous improvement occured as a rule at the age of 6 - 7 weeks. From the submitted results its may be concluded that the DCC syndrome is rather the manifestation of a certain immaturity of the hip joint than a disease in the proper sense of the word. Disease in the classical sense when the child begins to walk and the character of the anatomical development of the hip joint does not correspond to the functional demands laid on the hip joint. Key words: sonography, syndrome of congenital dysplasia of the hip joint.
