Clinical Insights into Developmental Dysplasia of the Hip: Risk Factors and Findings from a Turkish Pediatric Study

Aim: Limited research exists regarding the connection between
developmental dysplasia of the hip (DDH) and risk factors
within the Turkish population. This study aimed to explore the
potential associations between DDH and various risk factors
among Turkish children.
Material and Method: The study involved analyzing the
medical records of 83 children born in or admitted to Aksaray
Training and Research Hospital, with clinical indications of
hip dislocation (HD). The study delved into the relationships
between DDH and risk factors such as age under 3 years, female
gender, twinning, being the first-born child, C-section delivery,
breech presentation, prematurity, positive family history, and
the presence of associated abnormalities.
Results: Within the study group, HD was confirmed in 74
children (89%) as Positive HD, whereas 9 children (11%) were
ruled out as Negative HD. Subsequently, 12 children (14.4%)
were excluded from the initially positive cases, as their
diagnosis was confirmed to be paralytic hip dislocation rather
than DDH. Ultimately, DDH was verified in 62 children (74.6%).
Statistical analyses using the Chi-square test (χ²) and odds
ratios (OR) revealed notable associations between DDH and
positive family history, female gender, age below 3 years, and
the presence of associated abnormalities. The corresponding
P values and OR were 0.00 (16.5), 0.002 (3.1), 0.005 (2.6), and
0.042 (1.9) respectively.
Conclusion: Positive family history, female gender, age under
3 years, and the presence of associated abnormalities were
associated with an approximate 16-fold, 3-fold, 2.5-fold, and
2-fold increased risk of DDH respectively.
