Insights
Hip dysplasia is common, affecting 1 in 23 newborns. This condition is more prevalent in females and the left hip, with first-borns also at higher risk.
Area of Science:
- Pediatric Orthopedics
- Developmental Dysplasia of the Hip (DDH)
Context:
- Analysis of 40,243 births between 1981-1985.
- 1,747 cases of hip dysplasia, subluxation, or dislocation identified.
Purpose:
- To examine the frequency, sex distribution, affected hip, and birth order in hip dislocation.
- To highlight the importance of newborn screening for hip abnormalities.
Summary:
- Hip dislocation occurs in 4.3% of newborns in the study cohort.
- Females are disproportionately affected (5.3:1 ratio).
- The left hip is more commonly affected, and 50% of cases involve first-born children.
Impact:
- Emphasizes the need for thorough newborn examinations to detect hip dysplasia early.
- Provides epidemiological data on risk factors for hip dislocation.
- Informs clinical practice regarding screening protocols for developmental dysplasia of the hip.
Abstract:
During the period between 1981 to 1985, 40,243 children have been born. Among these children, 1,747 suffered from dysplasia, subluxation or dislocation of the hip. In this paper the following parameters are examined: frequency, sex, the hip affected and the order of birth. Dislocation of the hip is more frequent in females with a ratio of 5.3 to 1. The hip more frequently affected is the left. Fifty percent of the children affected are first-born. In this study we want to emphasize the importance of a thorough explanation of the newborn, due to the frequency of the affection and especially its greater frequency in female and its predominance in the left hip.
