Developmental dysplasia of the hip (DDH)
A free high-yield preview for the UKMLA Applied Knowledge Test. Below are the key points to recognise developmental dysplasia of the hip (ddh) — the full SA Note notes add investigations, management, complications and 10 practice questions.
Key high-yield points
- Female sex (4:1 female-to-male predominance - maternal hormones increase ligamentous laxity more in female fetuses)
- Breech presentation at or after 36 weeks gestation (regardless of final presentation at delivery or method of delivery - damage may occur before ECV/spontaneous version)
- Positive family history (first-degree relative with DDH)
- Firstborn child (less-stretched uterus, less room in utero)
Afro-Caribbean origin is NOT a risk factor for DDH - it is a favourite exam distractor. DDH is actually less common in people of African descent.
