Abstract

Introduction: Congenital dislocation of the hip joint is a defect in which the upper end of the thighbone (femur) is not properly located in the acetabulum socket. The present study aimed at determining the incidence and risk factors of congenital dislocation of the hip joint in the term infants born in Amirol-Momenin (PBUH) Hospital in the city of Zabol in the year 2016. Methods: This is a descriptive-analytical study of a cross-sectional type conducted on all the infants born in Amirol-Momenin (PBUH) Hospital in the city of Zabol in 2016 as the investigated statistical population. The gathered data were described in SPSS 18 using frequency, percentage, mean, and standard deviation indices analyzed using Chi-square test. p < 0.05 was considered to be significant. Results: In this study, 1400 infants born in the department of obstetrics and gynecology of Amirol-Momenin (PBUH) Hospital in 2016 were investigated, of whom 32 infants were diagnosed with developmental dysplasia of the hip using ortolani and Barlow tests, hence an incidence rate of 2.3 or 23 cases in every 1000 live births. Conclusion: The results of the present study showed that the incidence of DDH in this region is higher than its general incidence rate, which could be due to a specific ethnicity, the high rate of birth-giving in families, and the special lifestyle of the region. On the other hand, given that instability has a higher incidence than complete dislocation or dislocatability, the infants with DDH in the present study may be diagnosed with joint instability after radiologic examination. © 2017, Pharmainfo Publications.
