Frequency of Reported Cases of Developmental Dysplasia of the Hip in Kurdistan Region/Iraq

Background and objectives: Geographical location and ethnicity have an impact on the incidence and prevalence of developmental dysplasia of the hip (DDH). In Iraq, particularly in the Kurdistan Region, this information is not yet widely available. The goals of this investigation were to estimate the incidence and prevalence of DDH, as well as the total number of reported cases. Methods: Three official national database sources in the Kurdistan Region of Iraq were used to gather data for this cross-sectional study. The statistics include population, live births, and the number of DDH cases recorded for each year and governorate individually. For each year, DDH cases were divided by live births to calculate the incidence per 1000 live births, and by population to calculate the prevalence per 1000 population. Results: The previous 25 years (1998–2022) had 44972 DDH instances documented. In the Kurdistan Region of Iraq, the average annual incidence of DDH patients was 18.2 instances per 1000 live births. Over the previous 25 years, the average number of DDH cases in the area was 4.65 per 1000 people. Conclusion: The Kurdistan area has had an average annual DDH incidence of 18.2 cases per 1000 live births during the past 25 years, with a frequency of 4.65 cases per 1000 persons. The Duhok Governorate was found to have the greatest frequency and prevalence.
