Developmental dysplasia of the hip (DDH)
- A spectrum of conditions related to hip development in infants & young children
- Results from abnormal development of the acetabulum and proximal femur
- Results in mechanical instability of the hip joint
- Left hip (3:1) vs Right
- Female sex (5:1)
- Breech presentation (20%)
- Family history of DDH
- Infants and young children with untreated hip dislocation rarely have pain or other limitations.
- Most affected children begin to walk and reach developmental milestones at the appropriate time.
- In cultures where tight swaddling with the lower limbs in extension is common, significantly higher rates of DDH have been reported.
- In South Australia 79% of those with DDH were tightly swaddled
- In Japan, when traditional swaddling was used, the incidence of DDH was 5%.
- A public campaign to switch to wrapping techniques encouraging hip flexion and abduction led to DDH rates falling to less than 0.4%.
