πΌ Uneven thigh creases in your baby β scary, or totally normal?
Newborn babies get referred for this reason quite regularly and the research is actually really reassuring.
A 20-year study of babies referred specifically for asymmetric skin creases found that less than 2% had actual hip dysplasia.
Asymmetric thigh folds show up in up to 70% of completely normal babies. They can simply reflect positioning, fat distribution, or just normal variation.
What actually raises concern for DDH:
π΄ Abnormal Ortolani or Barlow test
π΄ Unequal hip abduction
π΄ Positive Galeazzi sign (leg length difference)
π΄ Asymmetry in the groin or buttock β not just the thigh
Risk factors that change the picture: breech presentation, family history of DDH or foot deformities.
If the hip exam is normal and there are no risk factors β isolated thigh crease asymmetry alone is very unlikely to mean hip dysplasia.
As always β if youβre worried, talk to your doctor. π
