Hip Dysplasia-Causes-Risk factors

Developmental Dislocation (Dysplasia) of the Hip (DDH)-Causes-Risk factors

DDH tends to run in families. It can be present in either hip and in any individual. It usually affects the left hip and is more common in:
 
  • Girls
  • Firstborn children
  • Babies born in the breech position (especially with feet up by the shoulders). The American Academy of Pediatrics now recommends ultrasound DDH screening of all female breech babies.
  • Family history of DDH (parents or siblings)
  • Oligohydramnios (low levels of amniotic fluid)

Clinical recommendation

Evidence rating

References

Risk factors for DDH should be identified in all children.

A careful physical examination is the basis for screening for DDH.

Ultrasonography should be ordered for infants six weeks to six months of age to clarify a clinical finding suggestive of DDH, assess a high-risk infant, and monitor DDH as it is observed or treated.

DDH = developmental dysplasia of the hip.

    
     

A = consistent, good-quality patient-oriented evidence; B = inconsistent or limited-quality patient-oriented evidence; C = consensus, disease-oriented evidence, usual practice, expert opinion, or case series. For information about the SORT evidence rating system, see page
