Hip dysplasia

Hip Dysplasia, also known as Developmental Hip Dysplasia (DDH) or congenital hip dysplasia, is a condition where the ball and socket part of the hip joint do not fit properly together in their normal position.

What is Hip Dysplasia?

The main cause is a combination of loose ligaments around the joint and abnormal growth or development. The severity of this condition can vary from mild dysplasia, to severe abnormal development where dislocation of the hip may occur.

As many as 1 in 6 full-term newborn babies have some form of hip instability at birth, and it tends to affect females more than males. However, it is not always present at birth, hence the ‘developmental’ part of the name. Risk factors for developing this condition include:

  • Incorrect swaddling techniques
  • Being a first born
  • Having family history of the condition
  • Breech positioning inside the womb

What are the signs and symptoms?

There are a wide variety of signs and symptoms for DDH. Depending on when you are diagnosed, you might experience:

  • Clicking or clunking when moving the hip
  • Uneven thigh or buttock skin creases
  • Uneven leg lengths
  • Weight-bearing to one side when sitting
  • Avoidance of weight bearing altogether
  • Limping or pain when walking
  • Walking on tip-toes on one side
  • Legs that are difficult to spread apart

What can be done about it?

Screening at birth, and in the weeks and months that follow, is the best way to reduce the risk of developing this condition, and its potential complications later in life. You should allow for your baby’s legs and hips to sit in their natural position where possible (i.e. knees bent and turned out at the hips). Try to avoid swaddling, as this restricts leg movement, and any car seats or carriers that bring your child’s legs in together at the knees.

In cases where Hip Dysplasia is present, there are a few different types of treatment, which include harnessing or bracing for milder cases, or surgical correction in more severe cases (i.e. dislocation).

One of the biggest side effects in adults is hip osteoarthritis, so from the teenage years and up, some cases may be considered for corrective surgery to avoid the risk of this developing later in life.
