The Numbers Game: What the Latest Meta-Analysis Tells Us About DDH in Infants
Developmental Dysplasia of the Hip (DDH) is a condition that has long puzzled the medical community. A recent systematic review and meta-analysis sheds light on its prevalence, especially among infants.

Prevalence of developmental dysplasia of the hip (DDH) in infants: a systematic review and meta-analysis by Zhongbin Tao et al. in 2023.
The Source Article's Abstract
To estimate the prevalence of developmental dysplasia of the hip (DDH) in infants with a systematic review and meta-analysis.
A literature search was conducted in April 2023, using databases such as Cochrane Library, PubMed, MEDLINE, CNKI, and SinoMed, without language restrictions. Eligible studies included cross-sectional studies reporting the prevalence of DDH among infants aged 0-12 months.
A total of 65 studies involving 3,451,682 infants were included in the meta-analysis. The pooled prevalence of DDH was 1.40% (95% CI: 0.86 to 2.28, I=100%), and prevalence of dysplasia, subluxation, and dislocation was 1.45% (95% CI: 0.93 to 2.24, I=97%), 0.37% (95% CI: 0.22 to 0.60, I=94%), and 0.21% (95% CI: 0.13 to 0.34, I=92%), respectively.
The prevalence of DDH among infants is approximately one in a 100, with girls being at higher risk. Though the prevalence of dysplasia has decreased, there is a slight upward trend in overall DDH. Therefore, routine screening for DDH in infants is recommended to prevent more serious developmental problems.

Girls vs Boys: A Gendered Look at DDH
The study reveals a startling gender gap in DDH prevalence. Girls are at a significantly higher risk, making gender a crucial factor in DDH screening.
This finding is not just a statistical anomaly; it has real-world implications for pediatric care and parental awareness.
Quality Over Quantity: Assessing the Studies
While the meta-analysis included a whopping 65 studies, not all were of high quality. This raises questions about the data’s reliability, although the sheer volume of the studies lends some weight to the findings.
Given the study’s impact, it’s crucial to scrutinize the quality of the included research.

What’s Next? The Implications of These Findings
The study’s findings are a call to action for routine screening for DDH, especially among girls. The data also serves as a baseline for future research and healthcare policies.
With DDH affecting nearly 1 in 100 infants, the study underscores the need for immediate and effective screening methods.
