ABSTRACT
Ultrasonography was used to establish the diagnosis of transient hip synovitis and the onset of Legg-Calvé-Perthes disease. A total of 115 patients presenting with 119 painful hips and the preliminary diagnosis of transient hip synovitis were reviewed. Hip effusion, resulting in capsular distension, was documented accurately with ultrasound. In nine patients, capsular distension persisted longer than 6 weeks and was associated with the onset of Legg-Calvé-Perthes disease.

The effect of ultrasonographic screening and treatment with a Pavlik harness on the incidence of developmental dislocation of the hip has been studied retrospectively. Observations were made at three different consecutive periods; in the first, clinical screening was carried out, in the second, ultrasonography was added for children up to 3 months of age, and in the third ultrasonography was used within the first few days of birth. A significantly decreased dislocation rate was demonstrated in each group, suggesting that early ultrasonography was of value in the early detection of dislocation.

The possible influence of early harness treatment for hip dysplasia--a treatment made possible by hip sonography according to Graf--on the incidence of hip luxations was examined in an epidemiological study. In a region with 8,000 births per year three periods were investigated: the pre-ultrasonographic era with 19 luxations per year (2.2/1000), the introductory era with 11 (1.3/1000) and the last period with 6 luxations so far (0.8/1000). A diagnosis can now be made at an earlier time due to the possibility of viewing the hip with sonography, a fact which significantly reduces the amount of hip luxations (pre-ultrasonographic era versus screening era: P = 0.00002), verified by the significant decrease in open and closed reductions.
