Incidence of Late-Diagnosed Developmental Dysplasia of the Hip-Dislocation in Colombia, 2010 to 2020

Among the spectrum of Developmental Dysplasia of the Hip (DDH), cases involving dislocation (DDH-dislocation) are not frequently examined in global epidemiological research. This ecological study estimates the incidence of late-diagnosed DDH-dislocation among Colombian children aged 3 months to 18 years, from 2010 to 2020. Data were drawn from the Individual Service Provision Records (SISPRO) and vital statistics provided by the National Administrative Department of Statistics (DANE). A total of 68 460 late-diagnosed DDH-dislocation cases were identified, with a female-to-male ratio of 2.2:1. Annual incidence ranged from 4.3 to 8.3 per 1000 live births. Elevated rates were concentrated in central <i>Cundiboyacense</i>, southern Santander, and the <i>Nariñense</i> Andean Massif regions. These findings underscore the need for a nationwide early detection program designed to reduce late diagnoses, especially in areas with higher incidence rates.
