Developmental Dysplasia of the Hip (DDH)

Question 1

What is developmental dysplasia of the hip?

Answer 1

DDH is abnormal development of the hip resulting in a shallow acetabulum (ball and socket join). Due to this shallow acetabulum, the pt experiences subluxation/ dislocation of the hip from the femur.

Question 2

What are common s/s of DDH?

Answer 2

-asymmetrical gluteal folds; this is known as the GALEAZZI SIGN
-positive ORTOLANI TEST- palpable clunk when knees bent 90 degrees are then abducted outwards
-positive BARLOW TEST- hip is popped out of socket with knees bent 90 degrees and adducted towards center

Question 3

What is treatment for DDH and is treatment time sensitive?

Answer 3

**Treatment for DDH has best results when started within first 2 months of life.

Pavlik Harnesses are used for pts less than 6 months of age and worn continuously for 3-5 months.

Spica Casts are used for older children or for children less than 6 months that did not have effective results with the Pavlik Harness.

–Traction may be used for kids with DDH if surgery is indicated. Similar to a spinal fusion, traction would be used pre-operatively to make any possible corrections that way first.
