Developmental Dysplasia of the Hip


Developmental dysplasia of the hip is a congenital condition where the hip is dislocated or unstable.

Causes are not clear but risk factors include:

  • Effect of the mother’s hormones especially relaxin
  • First child
  • Breech delivery
  • Heredity


  • Legs of different sizes
  • Abnormal gait
  • Uneven skin folds on the affected thigh
  • Hip joint that feels loose


  • Pavlik harness for babies younger than 6 months
  • Spica cast for older babies
  • Surgery to manipulate the hip bone in case of older babies who do not benefit from casting

Prevention is not possible but early detection can help in the treatment.
