The Epidemiology and Demographics of Hip Dysplasia
Figure 4
(a) The prevalence of DDH in the late 1970’s by age group in the Sámi living in northern Finland, Lake Inari region. The overall prevalence was 16.3; for those ≥60 years of age it was 60.2, and dropped to 3.5 for those 0–19 years of age. This has been attributed to a decrease in the practice of newborn swaddling using the gietka or komse. Data from Eriksson et al. [324]. (b) The marked decrease in DDH incidence in Japan after introduction of a nationwide educational program for both neonatal hip instability and hip dislocation after 3 months of age. For neonatal hip instability the data was taken from [84, 325] and for hip dislocation from [83–90].
