Although the developmental dysplasia of the hip (DDH) is well known to pediatric orthopedists, its etiology has still remained unknown and despite dedication of a vast majority of research, the results are still inadequate and confusing. The exact incidence of DDH and its relationship with known risk factors in Iran is still unknown. Here we represent the results of one year study on the incidence and related conditions of DDH.
Sonography was performed on the hip joints of 1073 full term healthy newborns at Imam Khomeini Hospital from March 2013 to March 2014. The results were classified according to Graf's classification. Pathologic hips were cross checked by the known risk factors for DDH.
A significant correlation was found between DDH and breech presentation (=0.000), torticollis (=0.004), metatarsus adductus (=0.024).
The incidence of DDH is significantly high in the studied group of neonates, suggesting reevaluation of current approach to DDH. The screening protocols need to be improved with the help of trained pediatricians and other health professions.
尽管小儿骨科医生对发育性髋关节发育不良（DDH）熟知已久，但其病因仍不明晰，尽管大量研究付出了努力，结果仍不充分且令人困惑。伊朗DDH的确切发病率及其与已知风险因素的关系仍不清楚。在此，我们展示了一项关于DDH发病率及相关情况的一年期研究结果。
2013年3月至2014年3月期间，对伊玛目霍梅尼医院1073名足月健康新生儿的髋关节进行了超声检查。结果根据格拉夫分类法进行分类。对病理性髋关节通过DDH的已知风险因素进行交叉核对。
发现DDH与臀位（=0.000）、斜颈（=0.004）、内收跖骨（=0.024）之间存在显著相关性。
在所研究的新生儿组中，DDH的发病率显著较高，这表明需要重新评估当前对DDH的处理方法。筛查方案需要在训练有素的儿科医生和其他卫生专业人员的帮助下加以改进。
