Developmental Dysplasia of Hip (DDH) or Congenital Hip Dislocation (CDH)

Hip joint is a ball & socket type joint. Sometimes the hip joints of an infant do not develop properly during early stages of foetal development. It results in to the unstable hip since birth. A careful examination can detect it early and can be treated early with good results. If left untreated can results in serious joint problem with gait abnormality.

Normally, an orthopaedic surgeon diagnoses congenital hip dislocation by examining the child’s hips and legs carefully. Barlow and Ortolani test are to be performed to diagnose the status of hip. These tests are screening test.

Recently Ultrasound of hip gives us accurate status of hip dysplagia. Ultrasound is a non-invasive and safe mode of investigation with high accuracy rate. X-rays can be done to diagnose the DDH if age of child is old.

Treatment

Treatment is depending on age and status of hip. If child is younger than six months then closed reduction and pavlik harness is helpful or closed reduction and spica cast can be given for few weeks. If it fails then it require surgery by performing either open reduction or closed reduction followed by casting.
